Dear valued JEA Water Customer:

JEA is pleased to send you the 2012 edition of the Water Quality Report and Water Conservation Guide.

This annual report, which utilities are required by federal regulation to distribute to all of their water

customers, provides a comprehensive view of what is in your drinking water. The report details the results

of our state-regulated water quality monitoring program.This comprehensive program involves the

collection and analysis of 25,000 water samples taken throughout the year to ensure that your water

supply is safe to drink. I encourage you to take a few minutes and look at the information presented in

the following pages.

Our community is very fortunate that its water source is the Floridan aquifer, located 800 to 1,200 feet

below the lands surface, and highly protected by a thick layer of clay which prevents chemicals from

entering the aquifer. Because the water is already so clean, it requires minimal treatment before leaving

the water plant and entering the distribution system. Most of the elements which are found in our

drinking water, and noted in this report, occur naturally in the aquifer at very low levels. Lead or copper

found in drinking water does not come from the JEA system, but rather from contact with householdplumbing fixtures.

Water conservation is a key component to delay the potential need for the development of far more

expensive drinking water sources. Not only will conservation protect the water quality of the aquifer, it will

also help to lower your bill. Check the back of this report for water conservation facts and helpful tips.

After more than three years of studies, in May of 2011, JEA received a 20-year renewal of our

Consumptive Use Permit from the St. Johns River Water Management District. JEA demonstrated that the

amount of water that we will withdrawal from the aquifer will have minimal impact to the quality of our

water resource. JEA will continue to work with our customers and State and Federal regulatory agencies

to ensure the protection of our water supply. We hope you find this report useful. If you would likeadditional copies of this report, they are available at JEA branches, public libraries and electronically

online on jea.com.

Sincerely

Your water source is the Floridan aquifer, which is one of the major sources of groundwater in the United

States. This highly productive aquifer system underlies all of Florida, southern Georgia, and small parts of

adjacent Alabama and South Carolinaa total area of about 100,000 square miles. Our abundant, fresh, clean

water supply is obtained by drilling wells deep into the aquifer. The water is then pumped to large water

reservoirs where it is aerated, chlorinated for disinfection, and then distributed via pumping stations to you and

other customers. In 2011 the Florida Department of Environmental Protection (FDEP) performed Source Water

Assessments on our systems. These assessments were conducted to

provide information about any potential sources of contamination in

the vicinity of our wells.The number of potential sources and

susceptibility level of contamination identified for all wells in our

systems are shown in the table below. Potential sources of

contamination indentified could include landfills, above and

underground fuel storage tanks, dry cleaning facilities, and wastewater

disposal areas. The assessment results are available on the FDEP

Source Water Assessment and Protection Program website at

www.dep.state.fl.us/swapp.

JEA customers within all of Duval County and parts of St. Johns County are located within either our Major Grid or

our small, hydraulically independent Mayport system. The Major Grid is comprised of 26 water treatment plants

(WTPs) and two storage and repump facilities that are fully interconnected. This system is supported by 115 active

wells and 64.5 million gallons of storage. These WTPs provide water to our customers through a water distribution

system consisting of approximately 4,058 miles of water distribution mains ranging from two inches to 36 inches

in diameter.The separate system in Mayport has two wells, 30,000 gallons of storage and three miles of water

distribution mains.

Our Nassau customers are provided water by the Lofton Oaks Grid consisting of six wells with 1.39 million gallons

of storage and 107 miles of distribution mains. Customers within the remaining parts of St. Johns County are provided water by the Ponte Vedra Grid (three wells

with 0.5 million gallons of storage and 31 miles of distribution mains), the Ponce de Leon Grid (four wells with 0.51 million gallons of storage and 13 miles of

distribution mains), and the Marsh Harbor and Palm Valley water systems (through an interconnection with St. Johns County Utility Department). JEA owns and

operates the Marsh Harbor and Palm Valley distribution systems.

These tables list the Total Hardness at eachWater Treatment Plant. These values are theaverage of the hardness from each of thewells servicing the plant, and were sampledin October December 2011.

What is Hard Water? Water is describedas hard when it contains high levels of

dissolved mineralsprimarily calcium and magnesium. These are naturally occurringsoluble compounds that are present in the aquifer.

Is it harmful? Hard water is not a health risk. Calcium and magnesium are bothimportant to human health and are commonly taken as supplements or as antacids.

Remove it with vinegar! Hard water leaves spots on dishes and windows, and abuildup of scale on plumbing fixtures and coffee pots. These can easily be dissolvedwith white distilled (common household) vinegar: Use vinegar in your dishwasher as a rinse-agent . Run it through a brewing cycle in your coffee pot then rinse

thoroughly . Soak faucets overnight in vinegar to remove corrosion.

To ensure the safety of our drinking water supply, JEA conducts a comprehensive monitoring program.We collect

samples from a citywide system of sample taps or faucets and then test them for more than 100 bacteriological

and chemical components. JEA also has in place a state-of-the-art operations network that can instantaneously

report areas of low pressure, and monitor and control chlorine.These improvements enable us to better monitor

our system and offer you an uninterrupted supply of fresh water.

WHY AM I GETTING A WATER QUALITY REPORT?

The Annual Water Quality Report (or Consumer Confidence Report) is intended for all customers of community

systems.This is an EPA requirement under the 1996 Safe Drinking Water Act Amendments and it is required that every customer receive this report by mail.

IMPORTANT INFORMATION ABOUT THE DATA IN THIS BOOKLET

JEA routinely monitors for contaminants in our drinking water according to federal and state laws, rules, and regulations. Except where indicated otherwise, this

report is based on the results of our monitoring for the period of January 1 to December 31, 2011.As authorized and approved by the Environmental Protection

Agency, the state has reduced monitoring for certain requirements to less than once per year because the concentrations of these contaminants are not expected to

vary significantly from year to year.Some of our data, though representative, is more than one year old.

The results consist of a listing of all contaminants detected in our drinking water during the sample period. Out of more than 100 contaminants for which JEA routinely

test, only those that have been detected appear in the tables.

WHY ARE THERE SO MANY CONTAMINANTS IN MY DRINKING WATER?

Actually, most of the contaminants present in our drinking water occur naturally in the aquifer or are picked up by the water as it travels over the surface o

land or through the ground. Lead and copper contaminants can occur from household plumbing fixtures.

CROSS CONNECTION CONTROL

JEA ensures the safety of the public drinking water through the Cross Connection Control Program. Cross connections occur anywhere the public water supply

connected to potentially contaminated water sources including commercial process water, irrigation and fire sprinkler systems, swimming pools and alternativ

water sources such as wells, reclaimed water and ponds. Under certain circumstances, potentially contaminated water may backflow from a customers

premise into the public water supply. By requiring the installation and annual inspection of backflow preventers on customer water connections, this vital

program protects the public water supply from possible contamination.

Our Cross Connection Control Programs goal is to prevent backflow, and the program is necessary to protect the health of our customers by keeping the wate

safe. For more information concerning this program, visit our Web site at

https://www.jea.com/Manage_My_Account/Forms_and_Policies/Commercial_Customers/Cross-Connection_Control.aspx.

IMPORTANT HEALTH INFORMATION

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised

persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with

HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections.These

people should seek advice about drinking water from their health care providers. EPA and CDC guidelines on appropriate

means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the EPAs Safe Drinking Water Hotline at 1-800-426-4791.

CONTAMINANT SOURCE INFORMATION

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of

the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the

presence of animals or from human activity. Contaminants that may be present in source water include:

(A) Microbial contaminants such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

(B) Inorganic contaminants such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater

discharges, oil and gas production, mining, or farming.

(C) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.

(D) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can

also come from gas stations, urban stormwater runoff, and septic systems.

(E) Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, EPA prescribes regulations, that limit the amount of certain contaminants in water provided by public water systems. Food and

Drug Administration (FDA) regulations establish limits for contaminants in bottled water that must provide the same protection for public health. Drinking water, including bottle

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 EPAs Safe Drinking Water Hotline 1-800-426-4791.

TERMS AND ABBREVIATIONS

In the data tables you will find many terms and abbreviations that may not be familiar. To help you better understand these terms, weve provided the following definitions

Action Le vel (AL) the concentration of a contaminant, which if exceeded, triggers treatment or other requirements that a water system must follow.

Initial Distribution System Evaluation (IDSE) The IDSE is a one-time study conducted by water systems to identify distribution system locations with high

concentrations of trihalomethanes (THMs) and haloacetic acids (HAAs) in order to select compliance monitoring locations for the Stage 2 Disinfection Byproducts Rule

(DBPR).

Maximum Contaminant Level (MCL) the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the

best available treatment technology.

Maximum Contaminant Level Goal (MCLG) the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a

margin of safety.

Maximum Residual Disinfectant Level (MRDL) the highest level of a disinfectant allowed in drinking water.There is convincing evidence that addition of a

disinfectant is necessary for control of microbial contaminants.

Maximum Residual Disinfectant Level Goal (MRDLG) the level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs donot reflect the benefits of the use of disinfectants to control microbial contaminants.

Non-Detect (ND) means not detected and indicates that the substance was not found by laboratory analysis.

Parts per billion (ppb) or Micrograms per liter (g/L) one part by weight of analyte to 1 billion parts by weight of the water sample.

Parts per million (ppm) or Milligrams per liter (mg/L) one part by weight of analyte to 1 million parts by weight of the water sample.

Picocuries per Liter (pCi/L) a measure of radioactivity in water.

Variances and Exemptions: State or EPA permission not to meet an MCL or a treatment technique under certain conditions.

NOTE: MCLs are set at stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink two liters of

water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect.

The following is general information and much of it does not necessarily pertain to JEA-supplied drinking water becauseof our deep-well, groundwater source.

ALL SYSTEMS If present,elevated levels of lead can cause serious health problems,especially for pregnant women and

young children. Lead in drinking water is primarily from materials and components associated with service lines and hom

plumbing. JEA is responsible for providing high quality drinking water,but cannot control the variety of materials used in

plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead

exposure by flushing your tap for 30 seconds to two minutes before using water for drinking or cooking. If you are

concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing

methods,and steps you can take to minimize exposure is available from EPAs Safe DrinkingWater Hotline,

1-800-426-4791, or at http://www.epa.gov/safewater/lead.

LOFTON OAKS GRID: Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other potentially harmful bacteria may be

present. Coliforms were found in more samples than allowed during the month of September and this was a warning of potential problems. Repeat sampling was initiated

and the results were satisfactory.The areas were flushed and adequate chlorine was maintained.

JEA has in place an Annual Water Resource Master Plan for all water resources. Included in this plan arestrategic capital improvements over the next 20 years which will support additional capacity for growth, reduce

costs, protect natural resources and provide increased reliability

while continuing to supply clean, safe water to our customers.

Planned improvements to the north and west portions of the

service area include a new regional water treatment plant

(Northwest Regional) and the expansion of two existing smaller

plants (Westlake and West Nassau). Several new major

transmission system piping improvements ranging from 16 to 36-

inches in size are planned to support

projected growth and to increase reliability.

In the south and east portion of the service area, JEA plans to construct two additional regional water

treatment facilities (Greenland and RiverTown). Several new major transmission system piping improvements ranging from 16 to 30-inches in size are

planned to support projected growth and to increase reliability.

In 2010, JEA began implementing the recommendation to construct additional transmission improvements outlined in the Total Water Management Plan.

Facilities planned are 36-inch, 30-inch, and 24-inch dedicated transmission mains to transport up to 24 million gallons per day from west to east across the

St. Johns River. The construction of this river crossing project is scheduled for completion by 2014.

As water from our current source of supply, the Floridan aquifer, becomes more limited, JEA is investigating the feasibility and expense of utilizing other

potential sources of water supply. JEA is committed to conservation and the use of reclaimed water to reduce how much water may be needed from these

more expensive alternative water supplies.

JEA MAJOR GRID VARIANCE: The St. Johns Forrest WTP has two pairs of wells (Floridan and shallow) which

are pumped simultaneously to blend the water to reduce sulfates that are naturally occurring in the Floridan

aquifer in northern St. Johns County. The St. Johns River Water Management District has reduced the use ofshallow wells due to the impacts on surrounding wetlands. EPA and available health data indicates that chroni

exposure to low levels of sulfates is not harmful to health.The current MCL for sulfate is 250 mg/L and is base

on aesthetic effects (i.e. taste and odor).The variance is in effect until such time that a sulfate level of 500

mg/L is either exceeded or FDEP adopts a primary MCL for sulfates that is more restrictive than 500 mg/L.

Why is there chlorine in my water?

Chlorine is required by the EPA to be maintained throughout public drinking

water distribution systems in order to protect health. Chlorination of

drinking water, used to kill or inactivate harmful organisms which can cause

diseases, has been called the most significant health advance of the 20th

century. Millions of people, mostly children, die each year in developing

countries due to diseases that could be prevented by the chlorination of

drinking water. JEA monitors over 300 separate locations throughout the

water distribution system each month to ensure the proper minimum

health-protecting levels of chlorine are maintained.

Tap Water vs. Bottled Water

You do not need to buy bottled water for health reasons since our drinking

water meets all federal and State drinking water standards. Bottled water

costs up to 1,000 times more per gallon than tap water, and is often more

expensive than todays high-priced gasoline on a per gallon basis. Bottled

water is not necessarily safer as it is not as well regulated since FDA

requirements for bottled water are not as stringent as EPAs for publicdrinking water systems. Additionally, nationwide, just 15% of the tens of

billions of bottles consumed each year are recycled, adding significantly

to the waste stream, as well as requiring millions of barrels of oil to

produce. As an alternative to purchasing bottled water, use a reusable

bottle and fill it with JEA tap water.

Why does my water have a

rotten egg odor?

The rotten egg odor in water is

hydrogen sulfide and is produced

by bacteria that break down

naturally-occurring sulfate in the

water. These bacteria usually

thrive in the warm environment of

hot water heaters. Increasing the water

temperature to 160 degrees Fahrenheit for several hours will kill the

bacteria in the water heater. Then the water heater should be well flushed

before using again to supply the house. Be sure to turn the temperature

back down too!

Should I install home water treatment equipment?

Since the water we deliver to you meets all federal and State drinking water

standards, the decision to install a point-of-use (POU) or point-of-entry

(POE) home water treatment device is a personal one. If you are concernedwith the aesthetic qualities of your water, such as taste, odor, and hardness,

you might consider a home treatment unit. These systems can cost

thousands of dollars, so before investing in a costly unit, make sure that the

system you intend to purchase can address your needs. Additionally, it

should be certified by NSF International, the Water Quality Association, or

Underwriters Laboratories, Inc. to ensure that the manufacturers

performance claims are tested and validated. Finally, be sure to follow the

directions for cleaning and maintaining the system in order to prevent the

growth of potentially harmful bacteria.

WaterSense is a partnership program

sponsored by the U.S. Environmental

Protection Agency. A product or service

with the WaterSense label is backed by

independent testing and certification.Products that bear the WaterSense

label meet all the

criteria in EPAs

specifications for

water efficiency

and performance,

so you can feel

confident that the

product is water efficient and works

well.WaterSense is partnering with

utilities (including JEA), water districts,

manufacturers, certified irrigation

professionals and others to encourage

more efficient water use.

It may come as a surprise that washing a load

of dishes in the dishwasher uses less water than

doing the same number of dishes by hand.

(Dishwashers also do a better job of killing

germs, because they use hotter water than you

would normally use if washing by hand.) For

each cycle, an ENERGY STAR qualified

dishwasher model uses about four gallons of

water; a non-qualified model uses about six

gallons.

Washing dishes with a dishwasher is more

efficient than washing them by hand, and an

ENERGY STAR qualified dishwasher is even

more efficient. Compared with washing dishes by hand, you

can save 5,000 gallons of water, $40 in

utility costs, and 230 hours of your time annually by using an ENERGY STAR qualified dishwasher. An ENERGY STAR qualified dishwasher uses one-third less water and at least 41 percent less energy

than a non-qualified model. By replacing a pre-1994 dishwasher with an ENERGY STAR qualified dishwasher, you can save at

least $30 in annual utility costs.

We Floridians love our pools.To keep

from having to use more water than

necessary to fill them, correct any leaks

or service problems as they occur -do

not allow problems with your pool to

linger. Properly maintain your pool tomaximize the useful life of the water.

Maintaining a proper chemical balance

will keep the water clear, clean and

safe, and regularly cleaning out debris

will keep it enticing on a hot day.With

proper maintenance, pools seldom

require draining. Be sure to consult a

Showering is one of the leading ways we use water

in the home, accounting for nearly 17 percent of

residential indoor water use, or about 30 gallons per

household per day.

The average household could save more than 2,300

gallons per year by installing high-performance showerheads.And since these water savings will reducedemands on water heaters, households will also save energy. In fact, a household could save 300

kilowatt hours of electricity annually, enough to power its television use for about a year.

Standard showerheads use 2.5 gallons of water per minute (gpm). High-performance showerheads that

earn the WaterSense label must demonstrate that they use no more than 2.0 gpm. The WaterSense

label also ensures that these products provide a satisfactory shower that is equal to or better than

conventional showerheads on the market.

Finding Leaks

Check the number or dial on your water meter,

then dont flush the toilet, run the faucet, or use

any water for two hours. At the end of the two

hours, check the water meter again. If the meter

does not read exactly the same, you probably

have a leak. Walk through your house listening

for running toilets and looking for drips.

Toilets

Find out if

your toilet is

leaking

silently by

placing a

drop of food

coloring in

the toilettank. If color

shows up in

the toilet

bowl after 15 minutes without flushing, you have

a leak. Many toilet leaks are caused because the

flapper is decayed or broken. You can easily

replace this inexpensive part of your toilet. If the

problem is not just an old flapper and your

family has to replace a leaky toilet, look for one

with the WaterSense label to save both water

and money on your familys water and sewer bill.

Faucets

Time how often

your faucet

drips. A leaky

faucet that drips

at the rate of

one drip per

second can

waste more than

3,000 gallons in

a year! The

washers and

gaskets that

hold your faucet

together can wear down

and cause drips.These parts usually can be

replaced easily and inexpensively.

Showerheads

Showerheads can also get old and leak, even

when the water is not on. A showerhead that

drops just 10 drips in a minute wastes more

than 500 gallons per year. Most leaky

showerheads can be fixed by making sure theyre

screwed in tight. Wrapping the showerhead in

pipe tape, a special tape available at hardware

stores, and using a wrench to tighten it will help.

Outdoors

Check your garden hose for leaks where it

connects to the side of the house. If it leaks

when the hose is turned on, make sure the hose

is screwed in tight. If that doesnt work, you may

need to replace the nylon or rubber hose washer

or wrap the spigot in pipe tape. If you have a

sprinkler system that waters your lawn, check the

system each spring before turning it on to make

sure the sprinklers were not broken during the

winter or have sprung any leaks.

Information from JEA, ENERGY STAR,WaterSense,

EnergyIdeas Clearinghouse and Iowa Energy

Center.

Faucets account for more than 15 percent of indoor household water use.

While turning off the faucet while brushing your teeth or washing dishes is

one way to save, there are also energy efficient products to reduce the

amount of water used when the tap is turned on. For instance, high-performance sink faucets can reduce a sinks water flow by 30 percent or

more without sacrificing performance. Or for just a few dollars, a small

screen device called a faucet aerator can be screwed onto the tip of your

faucetit adds air into the water stream so you can use less water to was

your hands or brush your teeth without noticing a difference in water flow.

Installing these faucets and faucet accessories can help the average

household save more than 500 gallons of water each year.And since youd

be using less water, the demand for electricity to heat the water is reduced

as well, helping you lower both your water and electric bills.
