Re PGampErsquos Report Under Ordering Paragraph 1b Amended Cleanup and Abatement Order No R6V-2011-0005A1

Dear Mr Singer Pacific Gas and Electric (PGampE) submits the following report in compliance with Ordering Paragraph 1b of Amended Cleanup and Abatement Order No R6V-2011-0005A1 (the ldquoOrderrdquo) issued October 11 2011 for the Hinkley Compressor Station PGampE has for many years acknowledged with genuine regret its responsibility for chromium contamination in the Hinkley community PGampE is committed to working cooperatively with the Lahontan Regional Board to expeditiously clean up groundwater contamination resulting from PGampErsquos historical operations at the Hinkley Compressor Station We share the mutual goal of ensuring safe reliable drinking water for the residents of Hinkley to ease their concerns for community health and well-being PGampE will continue to work diligently to gather the data required to comply with the Order however we have concerns that some of the Order provisions set infeasible technical and timing requirements for bottled water and permanent whole-house replacement water In addition as we previously advised you in our comment letter on the draft CAO PGampE believes that the CAO requirements are not supported by state law and PGampE has serious concerns that the CAO as written sets a troubling precedent for determination of replacement water in cases of groundwater contamination that has implications for water providers and consumers statewide To that end today PGampE submitted a petition and request for emergency stay to the State Water Resources Control Board While this petition is pending State Board action PGampE will continue to honor our commitment to provide safe drinking water to the community through our voluntary bottled water program and will work to comply with the CAO to the extent feasible using current tools and technologies including aggressively testing whole-house water technologies and report out on our progress to the Lahontan Regional Board and to the Hinkley community PGampE is also continuing our work with the Hinkley community to establish an independent panel of technical experts to advise them on technical and other matters of community interest

Mr Harold J Singer October 25 2011 Page 2 Ordering Paragraph 1a Requirements Ordering Paragraph 1a requires that PGampE supply interim uninterrupted replacement water service (ie bottled water or equivalent) to all those served by domestic and community wells in the affected area where those wells are determined to be ldquoimpactedrdquo For purposes of this report PGampE has relied upon the Order definition of ldquoimpacted wellsrdquo as including domestic or community wells in the affected area containing more than 31 microgL hexavalent chromium or more than 32 microgL total chromium We also believe this is in conformance with guidance you provided to Ms Tracy Egoscue of Paul Hastings LLC in an e-mail exchange concerning this requirement Copies of those e-mails are attached as Exhibit 1 to this report Ordering Paragraph 1b Requirements Order Paragraph 1b requires PGampE to submit a report to the Water Board listing all properties that have been provided interim uninterrupted water service which includes the following items

Addresses for each of the properties Well numbers Identification of the bottled water service providing the water Information on the quantity of bottled water being provided Evidence of any refusal of bottled water by a property owner who had been offered

interim uninterrupted water supply and Documentation to show that the interim water supply meets state primary and secondary

drinking water standards and hexavalent chromium levels of less than 002 microgL or the final maximum contaminant level once that standard is adopted by the California Department of Public Health (footnote 1 to paragraph 1b provides that ldquohellipfor the purposes of this standard drinking water must test below the reporting limit of 006 microgL due to the limitation of laboratory analysis of low levels of chromiumrdquo)

Documentation of Properties Provided Interim Uninterrupted Water Service Table 1 below reports the property owner name property address well number identification of the bottled water provider and information concerning the quantity of water delivered for each of the twelve properties for which PGampE is currently providing interim replacement water supply Please note that the quantities provided to each home may vary substantially from week to week as requested by the residents

Hexavalent chromium using EPA Method 2186 at a method reporting limit (MRL) of 006 microgL

Results from the analysis of the 5-gallon and 05-liter bottles are provided in Exhibits 6a and b respectively The results show that the interim water supply meets all Title 22 standards for measured constituents

Hexavalent chromium was not detected at an MRL of 006 microgL for both bottles of water Total chromium was not detected at a MRL of 10 microgL

Concentrations of all measured constituents (ie inorganic and organic contaminants

radionuclides disinfection by-products) meet Title 22 primary and secondary standards Although these results are considered final results by the analytical laboratory PGampE is undertaking an independent validation of the data to provide an additional level of review consistent with its practice for data collected under the Hinkley groundwater remediation project We will provide the results of that validation effort to the Water Board upon completion Advanced Technology Laboratories and Truesdail Laboratories Testing Samples of one 05-liter and one 5-gallon bottle of water from Culligan of Barstow were also provided to Advanced Technologies Laboratories (ATL) in Las Vegas Nevada and to Truesdail Laboratories in Tustin California on October 19 2011 Both are California-certified analytical laboratories The laboratories were asked to perform analyses for differing suites of analytes that taken together constitute the same suite of constituents analyzed for by MWH Final laboratory results for the hexavalent chromium analysis (performed by ATL) have been provided verbally by the laboratory Hexavalent chromium was detected in the sample from the 5-gallon container at a concentration of 008 microgL and was not detected in the 05-liter bottle sample at the method reporting limit of 006 microgL Culligan date and time stamps indicate that the ATL 5-gallon sample was bottled within two minutes of the 5-gallon sample analyzed by MWH PGampE will provide the Water Board a copy of the full reports from both laboratories as they are received As with the MWH results PGampE will perform an independent validation of the laboratory results and will forward the results of that validation to the Water Board as well ________________________________________

Culligan of Barstow ndash Water Quality Reports

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

IntroductionAt United Packaging Group LLC our goal is to deliver the highest quality beverage products through our professionally trained staff and Certified Quality Control programs We require that every product produced at United Packaging Group exceed many federal state and industry standards This is to ensure that every bottle delivered to our customers will have the highest quality and superior taste We have confidence in our on-going efforts to provide products of the highest possible quality and taste

The Food and Drug Administration (FDA) regulates tap water as provided by water utilities Under the Safe Drinking Water Act standards of quality enacted by the FDA for bottled water at a minimum must be as protective of the public health as EPArsquos Primary Drinking Water Standards (known as Maximum Contaminant Levels) for tap water Bottled water is required to be tested for the same parameters as tap water but the standards are in many cases stricter than for tap water Consumer safety is our primary objective in producing bottled water products for our customers

Types of Products Produced by United Packaging GroupUnited Packaging Group offers the following bottled water types in 100 recyclable single serve containers Purified Drinking Water Spring Drinking Water Purified Drinking Water with minerals and Flavored Water Beverages

Water Sources Utilized by United Packaging GroupUnited Packaging Group utilizes two sources of water for our bottled water products The first is the City of Colton Water Department The Colton Water Department provides water from one of the largest potable aquifers in the State of California therefore 100 of the Citys water comes from protected deepwater wells The water in these aquifers begins as rain and snow high up in our local mountains and it remains underground until we bring it to the surface Layers of solid rock and clay provide an impervious protective cover for the aquifer water The second source of water which gets labeled ldquospring waterrdquo must come from protected spring sources which are highly monitored and tested before being transported to our facility Both of our source waters are constantly tested to ensure that they are of the highest possible quality

Water ProcessingTreatmentBottled water products manufactured by United Packaging Group are safeguarded for your protection in two ways The first includes source protection and monitoring preformed by the City of Colton Water District and regulated by the EPArsquos (Environmental Protection Agency) Safe Drinking Water Act The second form of protection comes by the following in-process treatments which remove any potential chemical and or microbiological contaminants

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Reverse OsmosisThe reverse osmosis process removes much of the salt and or minerals in the source water and works by forcing water through semi permeable membranes at high pressure to force water against the natural osmotic gradient producing salt and mineral free water This ldquopurified waterrdquo is then extracted for bottling The byproduct a concentrated form of minerals and salts is then rejected as waste and disposed of

For United Packaging Groups ldquopurified drinking water with mineralsrdquo a very small amount of high quality minerals are added back into the purified water for improved hydration and taste Our ldquopurified drinking water with mineralsrdquo remains a Sodium Free product

Micron FiltrationMultiple types of filtration are used including carbon filtration micron filtration and particulate filtration to remove sediment and suspend particles These filters are pharmaceutical grade and are designed to remove particles as small as 02 micron in diameter

UV Light DisinfectionOur Ultraviolet disinfection consists of a purely physical chemical-free process UV-C radiation in particular with a wavelength in the 240 to 280 nanometers range attacks the vital DNA of any potential bacteriadirectly The radiation initiates a photochemical reaction that destroys the genetic information contained in the DNA The potential bacteria lose their reproductive capability and are destroyed Even potential parasites such as Cryptosporidia or Giardia which are extremely resistant to chemical disinfectants are efficiently destroyed with UV Light Disinfection

Ozone DisinfectionAll of our bottled water products are treated with Ozone prior to being bottled This is the final step to the highest level of purification We use ozone instead of chlorine because it leaves no residual and it quickly dissipates without imparting any odor or taste to the products Ozone is oxygen (O3) which is then bubbled through the water just before it is bottled into a clean sanitized container Within a few hours after the bottles have been filled and capped the ozone dissipates or converts back into the same form of oxygen we breath (O2)

Other notable processing and control measures

Spring Source Monitoring and ReceivingThe Spring Water utilized by United Packaging Group is collected using state-of-the-art equipment to prevent the chance of contamination and preserve the waterrsquos natural mineral content and taste Spring water

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

is transported to our facility in food quality sanitary stainless steel tankers and is then offloaded by trained Quality Assurance personnel Prior to transferring water to indoor storage tanks our QA personnel performs sample testing for signs of contamination All source waters are pumped through 100 food grade stainless steel piping

Bottling ProceduresBottling is performed under very controlled conditions using state-of-the-art equipment Bottles and caps are sourced through pre-approved vendors providing only the highest quality materials available All sourced materials are monitored and tested to meet internal standards All product waters are monitored during the filling and capping process to prevent contamination Each bottle is then given a specific code which identifies the date time of production andtype of water as well as the identification of the manufacturing plant

Water Quality TestingOur in-house laboratory is equipped with water testing machinery and staffed with trained experienced personnel Testing is performed daily on all of our water products in accordance with State and Federal regulatory standards We test for organic chemicals and inorganic chemicals as regulated by the FDA and the California Department of Public Heath No Contaminants were found above MCL were detected in 2009 There have been no violations of any FDA Standards of Quality we have not been required to test for any unregulated substances by the FDA or the State of California and no exemptions or variances have been granted by the California Department of Public Heath

Statement of Quality The standard (statement) of quality for bottled water is the highest level of a contaminant that is allowed in a container of bottled water as established by the United States Food and Drug Administration (FDA) and the California Department of Public Health

Statements

Drinking water including bottled water may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that water poses a health risk More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration Food and Cosmetic Hotline (1-888-723-3366)

For more information on FDA recalls httpwwwfdagovopacom7alertshtml

Some persons may be more vulnerable to contaminants in drinking water than the general population Immuno-compromised persons including but not limited to persons with cancer who are undergoing chemotherapy persons who have undergone organ transplants persons with HIVAIDS or other immune system disorders some elderly persons and infants can be particularly at risk from infections These persons should seek advice about drinking water from their health care providers The United States Environmental Protection Agency and the federal Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791)

The sources of bottled water include rivers lakes streams ponds reservoirs springs and wells As water naturally travels over the surface of the land or through the ground it can pick up naturally occurring substances as well as substances that are present due to animal and human activity Substances that may be present in the source water include any of the following(1) Inorganic substances including but not limited to salt sand metals that can be naturally occurring or result from farming urban storm water runoff industrial or domestic wastewater discharges or oil and gas production (2) Pesticides and herbicides that may come from a variety of sources including but not limited to agriculture urban storm water runoff and residential uses(3) Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations urban storm water runoff agricultural application and septic systems(4) Microbial organisms that may come from wildlife agricultural livestock

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

operations sewage treatment plants and septic systems(5) Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities

In order to ensure that bottled water is safe to drink the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

IntroductionAt United Packaging Group LLC our goal is to deliver the highest quality beverage products through our professionally trained staff and Certified Quality Control programs We require that every product produced at United Packaging Group exceed many federal state and industry standards This is to ensure that every bottle delivered to our customers will have the highest quality and superior taste We have confidence in our on-going efforts to provide products of the highest possible quality and taste

The Food and Drug Administration (FDA) regulates tap water as provided by water utilities Under the Safe Drinking Water Act standards of quality enacted by the FDA for bottled water at a minimum must be as protective of the public health as EPArsquos Primary Drinking Water Standards (known as Maximum Contaminant Levels) for tap water Bottled water is required to be tested for the same parameters as tap water but the standards are in many cases stricter than for tap water Consumer safety is our primary objective in producing bottled water products for our customers

Types of Products Produced by United Packaging GroupUnited Packaging Group offers the following bottled water types in 100 recyclable single serve containers Purified Drinking Water Spring Drinking Water Purified Drinking Water with minerals and Flavored Water Beverages

Water Sources Utilized by United Packaging GroupUnited Packaging Group utilizes two sources of water for our bottled water products The first is the City of Colton Water Department The Colton Water Department provides water from one of the largest potable aquifers in the State of California therefore 100 of the Citys water comes from protected deepwater wells The water in these aquifers begins as rain and snow high up in our local mountains and it remains underground until we bring it to the surface Layers of solid rock and clay provide an impervious protective cover for the aquifer water The second source of water which gets labeled ldquospring waterrdquo must come from protected spring sources which are highly monitored and tested before being transported to our facility Both of our source waters are constantly tested to ensure that they are of the highest possible quality

Water ProcessingTreatmentBottled water products manufactured by United Packaging Group are safeguarded for your protection in two ways The first includes source protection and monitoring preformed by the City of Colton Water District and regulated by the EPArsquos (Environmental Protection Agency) Safe Drinking Water Act The second form of protection comes by the following in-process treatments which remove any potential chemical and or microbiological contaminants

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Reverse OsmosisThe reverse osmosis process removes much of the salt and or minerals in the source water and works by forcing water through semi permeable membranes at high pressure to force water against the natural osmotic gradient producing salt and mineral free water This ldquopurified waterrdquo is then extracted for bottling The byproduct a concentrated form of minerals and salts is then rejected as waste and disposed of

For United Packaging Groups ldquopurified drinking water with mineralsrdquo a very small amount of high quality minerals are added back into the purified water for improved hydration and taste Our ldquopurified drinking water with mineralsrdquo remains a Sodium Free product

Micron FiltrationMultiple types of filtration are used including carbon filtration micron filtration and particulate filtration to remove sediment and suspend particles These filters are pharmaceutical grade and are designed to remove particles as small as 02 micron in diameter

UV Light DisinfectionOur Ultraviolet disinfection consists of a purely physical chemical-free process UV-C radiation in particular with a wavelength in the 240 to 280 nanometers range attacks the vital DNA of any potential bacteriadirectly The radiation initiates a photochemical reaction that destroys the genetic information contained in the DNA The potential bacteria lose their reproductive capability and are destroyed Even potential parasites such as Cryptosporidia or Giardia which are extremely resistant to chemical disinfectants are efficiently destroyed with UV Light Disinfection

Ozone DisinfectionAll of our bottled water products are treated with Ozone prior to being bottled This is the final step to the highest level of purification We use ozone instead of chlorine because it leaves no residual and it quickly dissipates without imparting any odor or taste to the products Ozone is oxygen (O3) which is then bubbled through the water just before it is bottled into a clean sanitized container Within a few hours after the bottles have been filled and capped the ozone dissipates or converts back into the same form of oxygen we breath (O2)

Other notable processing and control measures

Spring Source Monitoring and ReceivingThe Spring Water utilized by United Packaging Group is collected using state-of-the-art equipment to prevent the chance of contamination and preserve the waterrsquos natural mineral content and taste Spring water

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

is transported to our facility in food quality sanitary stainless steel tankers and is then offloaded by trained Quality Assurance personnel Prior to transferring water to indoor storage tanks our QA personnel performs sample testing for signs of contamination All source waters are pumped through 100 food grade stainless steel piping

Bottling ProceduresBottling is performed under very controlled conditions using state-of-the-art equipment Bottles and caps are sourced through pre-approved vendors providing only the highest quality materials available All sourced materials are monitored and tested to meet internal standards All product waters are monitored during the filling and capping process to prevent contamination Each bottle is then given a specific code which identifies the date time of production andtype of water as well as the identification of the manufacturing plant

Water Quality TestingOur in-house laboratory is equipped with water testing machinery and staffed with trained experienced personnel Testing is performed daily on all of our water products in accordance with State and Federal regulatory standards We test for organic chemicals and inorganic chemicals as regulated by the FDA and the California Department of Public Heath No Contaminants were found above MCL were detected in 2009 There have been no violations of any FDA Standards of Quality we have not been required to test for any unregulated substances by the FDA or the State of California and no exemptions or variances have been granted by the California Department of Public Heath

Statement of Quality The standard (statement) of quality for bottled water is the highest level of a contaminant that is allowed in a container of bottled water as established by the United States Food and Drug Administration (FDA) and the California Department of Public Health

Statements

Drinking water including bottled water may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that water poses a health risk More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration Food and Cosmetic Hotline (1-888-723-3366)

Some persons may be more vulnerable to contaminants in drinking water than the general population Immuno-compromised persons including but not limited to persons with cancer who are undergoing chemotherapy persons who have undergone organ transplants persons with HIVAIDS or other immune system disorders some elderly persons and infants can be particularly at risk from infections These persons should seek advice about drinking water from their health care providers The United States Environmental Protection Agency and the federal Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791)

The sources of bottled water include rivers lakes streams ponds reservoirs springs and wells As water naturally travels over the surface of the land or through the ground it can pick up naturally occurring substances as well as substances that are present due to animal and human activity Substances that may be present in the source water include any of the following(1) Inorganic substances including but not limited to salt sand metals that can be naturally occurring or result from farming urban storm water runoff industrial or domestic wastewater discharges or oil and gas production (2) Pesticides and herbicides that may come from a variety of sources including but not limited to agriculture urban storm water runoff and residential uses(3) Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations urban storm water runoff agricultural application and septic systems(4) Microbial organisms that may come from wildlife agricultural livestock

operations sewage treatment plants and septic systems(5) Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities

In order to ensure that bottled water is safe to drink the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

IntroductionAt United Packaging Group LLC our goal is to deliver the highest quality beverage products through our professionally trained staff and Certified Quality Control programs We require that every product produced at United Packaging Group exceed many federal state and industry standards This is to ensure that every bottle delivered to our customers will have the highest quality and superior taste We have confidence in our on-going efforts to provide products of the highest possible quality and taste

The Food and Drug Administration (FDA) regulates tap water as provided by water utilities Under the Safe Drinking Water Act standards of quality enacted by the FDA for bottled water at a minimum must be as protective of the public health as EPArsquos Primary Drinking Water Standards (known as Maximum Contaminant Levels) for tap water Bottled water is required to be tested for the same parameters as tap water but the standards are in many cases stricter than for tap water Consumer safety is our primary objective in producing bottled water products for our customers

Types of Products Produced by United Packaging GroupUnited Packaging Group offers the following bottled water types in 100 recyclable single serve containers Purified Drinking Water Spring Drinking Water Purified Drinking Water with minerals and Flavored Water Beverages

Water Sources Utilized by United Packaging GroupUnited Packaging Group utilizes two sources of water for our bottled water products The first is the City of Colton Water Department The Colton Water Department provides water from one of the largest potable aquifers in the State of California therefore 100 of the Citys water comes from protected deepwater wells The water in these aquifers begins as rain and snow high up in our local mountains and it remains underground until we bring it to the surface Layers of solid rock and clay provide an impervious protective cover for the aquifer water The second source of water which gets labeled ldquospring waterrdquo must come from protected spring sources which are highly monitored and tested before being transported to our facility Both of our source waters are constantly tested to ensure that they are of the highest possible quality

Water ProcessingTreatmentBottled water products manufactured by United Packaging Group are safeguarded for your protection in two ways The first includes source protection and monitoring preformed by the City of Colton Water District and regulated by the EPArsquos (Environmental Protection Agency) Safe Drinking Water Act The second form of protection comes by the following in-process treatments which remove any potential chemical and or microbiological contaminants

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Reverse OsmosisThe reverse osmosis process removes much of the salt and or minerals in the source water and works by forcing water through semi permeable membranes at high pressure to force water against the natural osmotic gradient producing salt and mineral free water This ldquopurified waterrdquo is then extracted for bottling The byproduct a concentrated form of minerals and salts is then rejected as waste and disposed of

For United Packaging Groups ldquopurified drinking water with mineralsrdquo a very small amount of high quality minerals are added back into the purified water for improved hydration and taste Our ldquopurified drinking water with mineralsrdquo remains a Sodium Free product

Micron FiltrationMultiple types of filtration are used including carbon filtration micron filtration and particulate filtration to remove sediment and suspend particles These filters are pharmaceutical grade and are designed to remove particles as small as 02 micron in diameter

UV Light DisinfectionOur Ultraviolet disinfection consists of a purely physical chemical-free process UV-C radiation in particular with a wavelength in the 240 to 280 nanometers range attacks the vital DNA of any potential bacteriadirectly The radiation initiates a photochemical reaction that destroys the genetic information contained in the DNA The potential bacteria lose their reproductive capability and are destroyed Even potential parasites such as Cryptosporidia or Giardia which are extremely resistant to chemical disinfectants are efficiently destroyed with UV Light Disinfection

Ozone DisinfectionAll of our bottled water products are treated with Ozone prior to being bottled This is the final step to the highest level of purification We use ozone instead of chlorine because it leaves no residual and it quickly dissipates without imparting any odor or taste to the products Ozone is oxygen (O3) which is then bubbled through the water just before it is bottled into a clean sanitized container Within a few hours after the bottles have been filled and capped the ozone dissipates or converts back into the same form of oxygen we breath (O2)

Other notable processing and control measures

Spring Source Monitoring and ReceivingThe Spring Water utilized by United Packaging Group is collected using state-of-the-art equipment to prevent the chance of contamination and preserve the waterrsquos natural mineral content and taste Spring water

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

is transported to our facility in food quality sanitary stainless steel tankers and is then offloaded by trained Quality Assurance personnel Prior to transferring water to indoor storage tanks our QA personnel performs sample testing for signs of contamination All source waters are pumped through 100 food grade stainless steel piping

Bottling ProceduresBottling is performed under very controlled conditions using state-of-the-art equipment Bottles and caps are sourced through pre-approved vendors providing only the highest quality materials available All sourced materials are monitored and tested to meet internal standards All product waters are monitored during the filling and capping process to prevent contamination Each bottle is then given a specific code which identifies the date time of production andtype of water as well as the identification of the manufacturing plant

Water Quality TestingOur in-house laboratory is equipped with water testing machinery and staffed with trained experienced personnel Testing is performed daily on all of our water products in accordance with State and Federal regulatory standards We test for organic chemicals and inorganic chemicals as regulated by the FDA and the California Department of Public Heath No Contaminants were found above MCL were detected in 2009 There have been no violations of any FDA Standards of Quality we have not been required to test for any unregulated substances by the FDA or the State of California and no exemptions or variances have been granted by the California Department of Public Heath

Definitions and Statements Required by California Law

Public Health Goal (PHG) The level of a contaminant in drinking water below which there is no known or expected risk to health PHGrsquos are health-protective goals set by the California Environmental Protection Agency

Maximum Contaminant Level (MCL) The highest level of a contaminant that is allowed in drinking water established by the US Environmental Protection Agency (EPA) or the California Department of Public Health

Primary Drinking Water Standards (PDWS) MCLrsquos for contaminants established by the US Environmental Protection Agency (EPA) or the California Department of Public Health that affect health along with their monitoring and reporting requirements and water treatment requirements

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Statement of Quality The standard (statement) of quality for bottled water is the highest level of a contaminant that is allowed in a container of bottled water as established by the United States Food and Drug Administration (FDA) and the California Department of Public Health

Statements

Drinking water including bottled water may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that water poses a health risk More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration Food and Cosmetic Hotline (1-888-723-3366)

For more information on FDA recalls httpwwwfdagovopacom7alertshtml

Some persons may be more vulnerable to contaminants in drinking water than the general population Immuno-compromised persons including but not limited to persons with cancer who are undergoing chemotherapy persons who have undergone organ transplants persons with HIVAIDS or other immune system disorders some elderly persons and infants can be particularly at risk from infections These persons should seek advice about drinking water from their health care providers The United States Environmental Protection Agency and the federal Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791)

The sources of bottled water include rivers lakes streams ponds reservoirs springs and wells As water naturally travels over the surface of the land or through the ground it can pick up naturally occurring substances as well as substances that are present due to animal and human activity Substances that may be present in the source water include any of the following(1) Inorganic substances including but not limited to salt sand metals that can be naturally occurring or result from farming urban storm water runoff industrial or domestic wastewater discharges or oil and gas production (2) Pesticides and herbicides that may come from a variety of sources including but not limited to agriculture urban storm water runoff and residential uses(3) Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations urban storm water runoff agricultural application and septic systems(4) Microbial organisms that may come from wildlife agricultural livestock

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

operations sewage treatment plants and septic systems(5) Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities

In order to ensure that bottled water is safe to drink the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

IntroductionAt United Packaging Group LLC our goal is to deliver the highest quality beverage products through our professionally trained staff and Certified Quality Control programs We require that every product produced at United Packaging Group exceed many federal state and industry standards This is to ensure that every bottle delivered to our customers will have the highest quality and superior taste We have confidence in our on-going efforts to provide products of the highest possible quality and taste

The Food and Drug Administration (FDA) regulates tap water as provided by water utilities Under the Safe Drinking Water Act standards of quality enacted by the FDA for bottled water at a minimum must be as protective of the public health as EPArsquos Primary Drinking Water Standards (known as Maximum Contaminant Levels) for tap water Bottled water is required to be tested for the same parameters as tap water but the standards are in many cases stricter than for tap water Consumer safety is our primary objective in producing bottled water products for our customers

Types of Products Produced by United Packaging GroupUnited Packaging Group offers the following bottled water types in 100 recyclable single serve containers Purified Drinking Water Spring Drinking Water Purified Drinking Water with minerals and Flavored Water Beverages

Water Sources Utilized by United Packaging GroupUnited Packaging Group utilizes two sources of water for our bottled water products The first is the City of Colton Water Department The Colton Water Department provides water from one of the largest potable aquifers in the State of California therefore 100 of the Citys water comes from protected deepwater wells The water in these aquifers begins as rain and snow high up in our local mountains and it remains underground until we bring it to the surface Layers of solid rock and clay provide an impervious protective cover for the aquifer water The second source of water which gets labeled ldquospring waterrdquo must come from protected spring sources which are highly monitored and tested before being transported to our facility Both of our source waters are constantly tested to ensure that they are of the highest possible quality

Water ProcessingTreatmentBottled water products manufactured by United Packaging Group are safeguarded for your protection in two ways The first includes source protection and monitoring preformed by the City of Colton Water District and regulated by the EPArsquos (Environmental Protection Agency) Safe Drinking Water Act The second form of protection comes by the following in-process treatments which remove any potential chemical and or microbiological contaminants

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Reverse OsmosisThe reverse osmosis process removes much of the salt and or minerals in the source water and works by forcing water through semi permeable membranes at high pressure to force water against the natural osmotic gradient producing salt and mineral free water This ldquopurified waterrdquo is then extracted for bottling The byproduct a concentrated form of minerals and salts is then rejected as waste and disposed of

For United Packaging Groups ldquopurified drinking water with mineralsrdquo a very small amount of high quality minerals are added back into the purified water for improved hydration and taste Our ldquopurified drinking water with mineralsrdquo remains a Sodium Free product

Micron FiltrationMultiple types of filtration are used including carbon filtration micron filtration and particulate filtration to remove sediment and suspend particles These filters are pharmaceutical grade and are designed to remove particles as small as 02 micron in diameter

UV Light DisinfectionOur Ultraviolet disinfection consists of a purely physical chemical-free process UV-C radiation in particular with a wavelength in the 240 to 280 nanometers range attacks the vital DNA of any potential bacteriadirectly The radiation initiates a photochemical reaction that destroys the genetic information contained in the DNA The potential bacteria lose their reproductive capability and are destroyed Even potential parasites such as Cryptosporidia or Giardia which are extremely resistant to chemical disinfectants are efficiently destroyed with UV Light Disinfection

Ozone DisinfectionAll of our bottled water products are treated with Ozone prior to being bottled This is the final step to the highest level of purification We use ozone instead of chlorine because it leaves no residual and it quickly dissipates without imparting any odor or taste to the products Ozone is oxygen (O3) which is then bubbled through the water just before it is bottled into a clean sanitized container Within a few hours after the bottles have been filled and capped the ozone dissipates or converts back into the same form of oxygen we breath (O2)

Other notable processing and control measures

Spring Source Monitoring and ReceivingThe Spring Water utilized by United Packaging Group is collected using state-of-the-art equipment to prevent the chance of contamination and preserve the waterrsquos natural mineral content and taste Spring water

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

is transported to our facility in food quality sanitary stainless steel tankers and is then offloaded by trained Quality Assurance personnel Prior to transferring water to indoor storage tanks our QA personnel performs sample testing for signs of contamination All source waters are pumped through 100 food grade stainless steel piping

Bottling ProceduresBottling is performed under very controlled conditions using state-of-the-art equipment Bottles and caps are sourced through pre-approved vendors providing only the highest quality materials available All sourced materials are monitored and tested to meet internal standards All product waters are monitored during the filling and capping process to prevent contamination Each bottle is then given a specific code which identifies the date time of production andtype of water as well as the identification of the manufacturing plant

Water Quality TestingOur in-house laboratory is equipped with water testing machinery and staffed with trained experienced personnel Testing is performed daily on all of our water products in accordance with State and Federal regulatory standards We test for organic chemicals and inorganic chemicals as regulated by the FDA and the California Department of Public Heath No Contaminants were found above MCL were detected in 2009 There have been no violations of any FDA Standards of Quality we have not been required to test for any unregulated substances by the FDA or the State of California and no exemptions or variances have been granted by the California Department of Public Heath

Definitions and Statements Required by California Law

Public Health Goal (PHG) The level of a contaminant in drinking water below which there is no known or expected risk to health PHGrsquos are health-protective goals set by the California Environmental Protection Agency

Maximum Contaminant Level (MCL) The highest level of a contaminant that is allowed in drinking water established by the US Environmental Protection Agency (EPA) or the California Department of Public Health

Primary Drinking Water Standards (PDWS) MCLrsquos for contaminants established by the US Environmental Protection Agency (EPA) or the California Department of Public Health that affect health along with their monitoring and reporting requirements and water treatment requirements

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Statement of Quality The standard (statement) of quality for bottled water is the highest level of a contaminant that is allowed in a container of bottled water as established by the United States Food and Drug Administration (FDA) and the California Department of Public Health

Statements

Drinking water including bottled water may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that water poses a health risk More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration Food and Cosmetic Hotline (1-888-723-3366)

For more information on FDA recalls httpwwwfdagovopacom7alertshtml

Some persons may be more vulnerable to contaminants in drinking water than the general population Immuno-compromised persons including but not limited to persons with cancer who are undergoing chemotherapy persons who have undergone organ transplants persons with HIVAIDS or other immune system disorders some elderly persons and infants can be particularly at risk from infections These persons should seek advice about drinking water from their health care providers The United States Environmental Protection Agency and the federal Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791)

The sources of bottled water include rivers lakes streams ponds reservoirs springs and wells As water naturally travels over the surface of the land or through the ground it can pick up naturally occurring substances as well as substances that are present due to animal and human activity Substances that may be present in the source water include any of the following(1) Inorganic substances including but not limited to salt sand metals that can be naturally occurring or result from farming urban storm water runoff industrial or domestic wastewater discharges or oil and gas production (2) Pesticides and herbicides that may come from a variety of sources including but not limited to agriculture urban storm water runoff and residential uses(3) Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations urban storm water runoff agricultural application and septic systems(4) Microbial organisms that may come from wildlife agricultural livestock

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

operations sewage treatment plants and septic systems(5) Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities

In order to ensure that bottled water is safe to drink the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies

Reverse OsmosisThe reverse osmosis process removes much of the salt and or minerals in the source water and works by forcing water through semi permeable membranes at high pressure to force water against the natural osmotic gradient producing salt and mineral free water This ldquopurified waterrdquo is then extracted for bottling The byproduct a concentrated form of minerals and salts is then rejected as waste and disposed of

For United Packaging Groups ldquopurified drinking water with mineralsrdquo a very small amount of high quality minerals are added back into the purified water for improved hydration and taste Our ldquopurified drinking water with mineralsrdquo remains a Sodium Free product

Micron FiltrationMultiple types of filtration are used including carbon filtration micron filtration and particulate filtration to remove sediment and suspend particles These filters are pharmaceutical grade and are designed to remove particles as small as 02 micron in diameter

UV Light DisinfectionOur Ultraviolet disinfection consists of a purely physical chemical-free process UV-C radiation in particular with a wavelength in the 240 to 280 nanometers range attacks the vital DNA of any potential bacteriadirectly The radiation initiates a photochemical reaction that destroys the genetic information contained in the DNA The potential bacteria lose their reproductive capability and are destroyed Even potential parasites such as Cryptosporidia or Giardia which are extremely resistant to chemical disinfectants are efficiently destroyed with UV Light Disinfection

Ozone DisinfectionAll of our bottled water products are treated with Ozone prior to being bottled This is the final step to the highest level of purification We use ozone instead of chlorine because it leaves no residual and it quickly dissipates without imparting any odor or taste to the products Ozone is oxygen (O3) which is then bubbled through the water just before it is bottled into a clean sanitized container Within a few hours after the bottles have been filled and capped the ozone dissipates or converts back into the same form of oxygen we breath (O2)

Other notable processing and control measures

Spring Source Monitoring and ReceivingThe Spring Water utilized by United Packaging Group is collected using state-of-the-art equipment to prevent the chance of contamination and preserve the waterrsquos natural mineral content and taste Spring water

is transported to our facility in food quality sanitary stainless steel tankers and is then offloaded by trained Quality Assurance personnel Prior to transferring water to indoor storage tanks our QA personnel performs sample testing for signs of contamination All source waters are pumped through 100 food grade stainless steel piping

Bottling ProceduresBottling is performed under very controlled conditions using state-of-the-art equipment Bottles and caps are sourced through pre-approved vendors providing only the highest quality materials available All sourced materials are monitored and tested to meet internal standards All product waters are monitored during the filling and capping process to prevent contamination Each bottle is then given a specific code which identifies the date time of production andtype of water as well as the identification of the manufacturing plant

Water Quality TestingOur in-house laboratory is equipped with water testing machinery and staffed with trained experienced personnel Testing is performed daily on all of our water products in accordance with State and Federal regulatory standards We test for organic chemicals and inorganic chemicals as regulated by the FDA and the California Department of Public Heath No Contaminants were found above MCL were detected in 2009 There have been no violations of any FDA Standards of Quality we have not been required to test for any unregulated substances by the FDA or the State of California and no exemptions or variances have been granted by the California Department of Public Heath

Definitions and Statements Required by California Law

Public Health Goal (PHG) The level of a contaminant in drinking water below which there is no known or expected risk to health PHGrsquos are health-protective goals set by the California Environmental Protection Agency

Maximum Contaminant Level (MCL) The highest level of a contaminant that is allowed in drinking water established by the US Environmental Protection Agency (EPA) or the California Department of Public Health

Primary Drinking Water Standards (PDWS) MCLrsquos for contaminants established by the US Environmental Protection Agency (EPA) or the California Department of Public Health that affect health along with their monitoring and reporting requirements and water treatment requirements

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Statement of Quality The standard (statement) of quality for bottled water is the highest level of a contaminant that is allowed in a container of bottled water as established by the United States Food and Drug Administration (FDA) and the California Department of Public Health

Statements

Drinking water including bottled water may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that water poses a health risk More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration Food and Cosmetic Hotline (1-888-723-3366)

For more information on FDA recalls httpwwwfdagovopacom7alertshtml

Some persons may be more vulnerable to contaminants in drinking water than the general population Immuno-compromised persons including but not limited to persons with cancer who are undergoing chemotherapy persons who have undergone organ transplants persons with HIVAIDS or other immune system disorders some elderly persons and infants can be particularly at risk from infections These persons should seek advice about drinking water from their health care providers The United States Environmental Protection Agency and the federal Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791)

The sources of bottled water include rivers lakes streams ponds reservoirs springs and wells As water naturally travels over the surface of the land or through the ground it can pick up naturally occurring substances as well as substances that are present due to animal and human activity Substances that may be present in the source water include any of the following(1) Inorganic substances including but not limited to salt sand metals that can be naturally occurring or result from farming urban storm water runoff industrial or domestic wastewater discharges or oil and gas production (2) Pesticides and herbicides that may come from a variety of sources including but not limited to agriculture urban storm water runoff and residential uses(3) Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations urban storm water runoff agricultural application and septic systems(4) Microbial organisms that may come from wildlife agricultural livestock

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

operations sewage treatment plants and septic systems(5) Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities

In order to ensure that bottled water is safe to drink the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies

is transported to our facility in food quality sanitary stainless steel tankers and is then offloaded by trained Quality Assurance personnel Prior to transferring water to indoor storage tanks our QA personnel performs sample testing for signs of contamination All source waters are pumped through 100 food grade stainless steel piping

Bottling ProceduresBottling is performed under very controlled conditions using state-of-the-art equipment Bottles and caps are sourced through pre-approved vendors providing only the highest quality materials available All sourced materials are monitored and tested to meet internal standards All product waters are monitored during the filling and capping process to prevent contamination Each bottle is then given a specific code which identifies the date time of production andtype of water as well as the identification of the manufacturing plant

Water Quality TestingOur in-house laboratory is equipped with water testing machinery and staffed with trained experienced personnel Testing is performed daily on all of our water products in accordance with State and Federal regulatory standards We test for organic chemicals and inorganic chemicals as regulated by the FDA and the California Department of Public Heath No Contaminants were found above MCL were detected in 2009 There have been no violations of any FDA Standards of Quality we have not been required to test for any unregulated substances by the FDA or the State of California and no exemptions or variances have been granted by the California Department of Public Heath

Please call (951)340-440 or visit wwwunitedpackaginggroupcom for a water quality analysis

Definitions and Statements Required by California Law

Public Health Goal (PHG) The level of a contaminant in drinking water below which there is no known or expected risk to health PHGrsquos are health-protective goals set by the California Environmental Protection Agency

Maximum Contaminant Level (MCL) The highest level of a contaminant that is allowed in drinking water established by the US Environmental Protection Agency (EPA) or the California Department of Public Health

Primary Drinking Water Standards (PDWS) MCLrsquos for contaminants established by the US Environmental Protection Agency (EPA) or the California Department of Public Health that affect health along with their monitoring and reporting requirements and water treatment requirements

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Statement of Quality The standard (statement) of quality for bottled water is the highest level of a contaminant that is allowed in a container of bottled water as established by the United States Food and Drug Administration (FDA) and the California Department of Public Health

Statements

Drinking water including bottled water may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that water poses a health risk More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration Food and Cosmetic Hotline (1-888-723-3366)

For more information on FDA recalls httpwwwfdagovopacom7alertshtml

Some persons may be more vulnerable to contaminants in drinking water than the general population Immuno-compromised persons including but not limited to persons with cancer who are undergoing chemotherapy persons who have undergone organ transplants persons with HIVAIDS or other immune system disorders some elderly persons and infants can be particularly at risk from infections These persons should seek advice about drinking water from their health care providers The United States Environmental Protection Agency and the federal Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791)

The sources of bottled water include rivers lakes streams ponds reservoirs springs and wells As water naturally travels over the surface of the land or through the ground it can pick up naturally occurring substances as well as substances that are present due to animal and human activity Substances that may be present in the source water include any of the following(1) Inorganic substances including but not limited to salt sand metals that can be naturally occurring or result from farming urban storm water runoff industrial or domestic wastewater discharges or oil and gas production (2) Pesticides and herbicides that may come from a variety of sources including but not limited to agriculture urban storm water runoff and residential uses(3) Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations urban storm water runoff agricultural application and septic systems(4) Microbial organisms that may come from wildlife agricultural livestock

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

operations sewage treatment plants and septic systems(5) Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities

In order to ensure that bottled water is safe to drink the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

Statement of Quality The standard (statement) of quality for bottled water is the highest level of a contaminant that is allowed in a container of bottled water as established by the United States Food and Drug Administration (FDA) and the California Department of Public Health

Statements

Drinking water including bottled water may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that water poses a health risk More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration Food and Cosmetic Hotline (1-888-723-3366)

For more information on FDA recalls httpwwwfdagovopacom7alertshtml

Some persons may be more vulnerable to contaminants in drinking water than the general population Immuno-compromised persons including but not limited to persons with cancer who are undergoing chemotherapy persons who have undergone organ transplants persons with HIVAIDS or other immune system disorders some elderly persons and infants can be particularly at risk from infections These persons should seek advice about drinking water from their health care providers The United States Environmental Protection Agency and the federal Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791)

The sources of bottled water include rivers lakes streams ponds reservoirs springs and wells As water naturally travels over the surface of the land or through the ground it can pick up naturally occurring substances as well as substances that are present due to animal and human activity Substances that may be present in the source water include any of the following(1) Inorganic substances including but not limited to salt sand metals that can be naturally occurring or result from farming urban storm water runoff industrial or domestic wastewater discharges or oil and gas production (2) Pesticides and herbicides that may come from a variety of sources including but not limited to agriculture urban storm water runoff and residential uses(3) Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations urban storm water runoff agricultural application and septic systems(4) Microbial organisms that may come from wildlife agricultural livestock

United Packaging Group LLCrsquos Bottled Water Quality Report1601 E Steel Rd Colton CA 91761

operations sewage treatment plants and septic systems(5) Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities

In order to ensure that bottled water is safe to drink the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies
