  • WATER POLLUTANTS

    AND THEIR SOURCES

    WATER

    is a chemical substance with the chemical formula H2O. Its molecule

    contains one oxygen and two hydrogen atoms connected

    by covalent bonds.

    covers 70.9% of the Earth's surface, and is vital for all known forms

    of life.

    it is found mostly in oceans and other large water bodies, with 1.6% of

    water below ground in aquifers and 0.001% in the air as vapor,

    clouds (formed of solid and liquid water particles suspended in air),

    and precipitation.

    WATER CYCLE

    known scientifically as the hydrologic cycle

    refers to the continuous exchange of water within the hydrosphere,

    between the atmosphere, soil water, surface water, groundwater, and

    plants.

    Water moves perpetually through each of these regions in the water

    cycle consisting of following transfer processes:

  • 1. Evaporation from oceans and other water bodies into the air

    and transpiration from land plants and animals into air.

    2. Precipitation, from water vapor condensing from the air and

    falling to earth or ocean.

    3. Runoff from the land usually reaching the sea.

    Water pollution

    is the contamination of water bodies.

    Water pollution affects, plants, and organisms living in these bodies of

    water; and, in almost all cases the effect is damaging not only to

    individual species and populations, but also to the natural biological

    communities.

    Water pollution is a major global problem

    CATEGORIES OF WATER

    SURFACE WATER

    Water that are found on the surface of the earth.

    Seeps through the soil and ground and eventually becomes ground water.

    CLASSIFICATION OF SURFACE WATER POLLUTION

    POINT SOURCES

  • refers to contaminants that enter a waterway from a single, identifiable

    source, such as a pipe or ditch.

    The CWA definition of point source was amended in 1987 to include

    municipal storm sewer systems, as well as industrial storm water, such

    as from construction sites.

    NON-POINT

    SOURCES

    refers to diffuse contamination that does not originate from a single

    discrete source. NPS pollution is often the cumulative effect of small

    amounts of contaminants gathered from a large area.

    Instructions to identify the source of pollution

    Point Source Pollution

    Inspect major animal farm "factories" where there are large amounts of

    chicken coops, swineherds in cages and cows kept in pens.

    Tour your community's water treatment plant. Determine if the tests are

    appropriate to clean the water before it returns to the holding system.

    Think about what the water looks like when you go swimming. Consider

    whether you would want to enter the water you are inspecting.

    GROUND WATER

    Water that are found under ground.

  • CAUSES OF GROUND ACQUIFERS

    wide spectrum of chemicals

    pathogens

    elevated temperature

    PATHOGENS

    COLIFORM BACTERIA are a commonly used bacterial indicator of water

    pollution, although not an actual cause of disease.

    High levels of pathogens may result from inadequately

    treated sewage discharges. This can be caused by a sewage plant

    designed with less than secondary treatment (more typical in less-

    developed countries).

    CHEMICAL AND OTHER CONTAMINANTS

    Organic water pollutants

    Detergents

    Disinfection by-products found in chemically disinfected drinking water,

    such as chloroform

    Food processing waste, which can include oxygen-demanding substances,

    fats and grease

  • Insecticides and herbicides, a huge range of organohalides and

    other chemical compounds

    Petroleum hydrocarbons, including fuels (gasoline, diesel fuel, jet fuels,

    and fuel oil) and lubricants (motor oil), and fuel combustion by products,

    from storm water runoff

    Tree and bush debris from logging operations

    Volatile organic compounds (VOCs), such as industrial solvents, from

    improper storage. Chlorinated solvents, which are dense non-aqueous

    phase liquids (DNAPLs), may fall to the bottom of reservoirs, since they

    don't mix well with water and are denser.

    Various chemical compounds found in

    personal hygiene and cosmetic products

    Inorganic water pollutants

    Acidity caused by industrial discharges (especially sulfur

    dioxide from power plants)

    Ammonia from food processing waste

    Chemical waste as industrial by-products

    Fertilizers containing nutrients--nitrates and phosphates--which are

    found in storm water runoff from agriculture, as well as commercial and

    residential use

  • Heavy metals from motor vehicles (via urban storm water

    runoff) and acid mine drainage

    Silt (sediment) in runoff from construction sites, logging, slash and

    burn practices or land clearing sites

    Macroscopic pollution

    large visible items polluting the watermay be termed "floatables" in an

    urban storm water context, or marine debris when found on the open

    seas

    Trash or garbage (e.g. paper, plastic, or food waste) discarded by people

    on the ground, along with accidental or intentional dumping of rubbish,

    that are washed by rainfall into storm drains and eventually discharged

    into surface waters

    Nurdles, small ubiquitous waterborne plastic pellets

    Shipwrecks, large derelict ships

    Safeguarding our Groundwater Supply

    For example:

    leaking underground storage tanks can be replaced by tanks that will

    not corrode

  • landfills can be sited in locations where leachates will not contaminate

    underlying groundwater

    and the impacts of spills of hazardous materials reduced by restricting

    access to recharge areas.

    Thermal pollution

    is the rise or fall in the temperature of a natural body of water caused by

    human influence.

    unlike chemical pollution, results in a change in the physical properties

    of water.

    A common cause of thermal pollution is the use of water as a coolant by

    power plants and industrial manufacturers.

    can also be caused by the release of very cold water from the base

    of reservoirs into warmer rivers.

    SOURCES OF THERMAL POLLUTION

    Removal of trees along the shore line

    Power plants

    Dumping of waste warm water by nuclear plants.

    EFFECTS OF THERMAL POLLUTION IN WATER

  • Sudden and peroiodic increase in temperature producing a

    thermal effect

    Changed dissolved oxygen

    distribution of organisms among major and minor communities.

    Death of steno hermic animals

    Changes to reproductive powers and increased susceptibility to disease

    production of heat shock proteins for thermotolerance.

    Control of Thermal Pollution

    Construction of cooling ponds

    Construction of cooling towers for radiation.

    Use cogeneration where the heat is recycled

    MAJOR WATER POLLUTANTS

    Arsenic

  • is an odorless and tasteless semi-metal element. It finds its way into

    drinking water supplies from agricultural and industrial practices and

    natural deposits in the earth.

    It is associated with several health hazards such as thickening and

    discoloration of the skin, nausea, vomiting, stomachaches, diarrhea and

    even partial paralysis and blindness. In extreme cases it can even lead to

    cancer.

    Lead

    is also a pollutant that affects drinking water.

    Excessive lead can lead to delays in physical and mental development, as

    well as learning disabilities and poor attention spans amongst children.

    Contaminated Sediments

    Several contaminants affect the sediments in natural water sources. In

    some form or the other, they flow from virtually every human habitation,

    whether agricultural or urban. Some of the most problematic sources of

    contaminants are industrial and municipal waste discharges.

    Mercury

    gets into surface water through rocks, soil, industrial activities and

    wastewater treatment facilities.

    This metal is extremely dangerous for fish and the animals that eat them.

    Disinfectants

  • added to drinking water to protect it from microbial pathogens, which

    are also very dangerous pollutants.

    WATER QUALITY MANAGEMENT IN RIVERS AND LAKES

    WATER QUALITY MANAGEMENT IN RIVERS

    Water Quality Management

    - to control the discharge of pollutants so the water quality is at an

    acceptable level.

    Factors to consider for water quality management in rivers:

  • Nature of pollutants

    Unique characteristics of the individual river

    Important Characteristics

    Surrounding vegetation

    Climate of the region

    Mineral heritage of watershed

    Land use patterns

    Types of aquatic life in the river

    Effects of oxygen-demanding wastes on rivers

    Causes depletion of the dissolved oxygen in the water

    May endanger aquatic life

    Biochemical Oxygen Demand (BOD)

    Theoretical oxygen demand (ThOD) depends on chemical composition

    to know the amount of oxygen needed to oxidize a substance to carbon

    dioxide and water.

    Chemical Oxygen Demand (COD) contrast to ThOD

  • COD Test a test which uses a strong oxidizing agent mixed in the water

    sample and boiled.

    *The difference between the amount of oxidizing agent used at the

    beginning and that remaining at the end of the test is used to calculate

    the COD*

    Biochemical Oxygen Demand (BOD)

    BOD - the chemical procedure to determine the intake rate of dissolved

    oxygen by the microorganisms

    BOD Test most widely used method of measuring organ matter as well

    as measuring the change in dissolved oxygen concentration

    Aerobic decomposition the process in which the microorganisms uses

    oxygen as it consumes waste

    Ultimate BOD maximum oxygen consumption possible when waste has

    been completely degraded

    Biochemical Oxygen Demand (BOD)

    Method 1: Low BOD Levels (0 6 mg/L)

  • BOD is calculated from two separate dissolved oxygen measurements

    made using the Dissolved Oxygen Probe. The initial dissolved oxygen

    reading is taken at the sampling site using the procedures outlined in

    Test 5. Using a light-free sample bottle, a water sample is collected at the

    same site. The sample is transported back to the lab and incubated at

    20C for a total of five days. After five days, the incubated sample is

    tested for dissolved oxygen. The oxygen reading at the end of the five

    days is subtracted from the initial reading. The resulting value is the

    BOD level.

    Biochemical Oxygen Demand (BOD)

    Method 2: High BOD Levels (> 6 mg/L)

    This method is recommended when testing stagnant or polluted waters,

    in which all of the dissolved oxygen may be consumed before the end of

    the 5-day period. The initial dissolved oxygen test, sampling, storage and

    incubation, are performed in the same manner as found in Method 1.

    Differences for Method 2 are:

    Five water samples are collected.

    A sample is tested for dissolved oxygen every 24 hours for five days.

    If, before the fifth day, the dissolved oxygen concentration falls below

    2 mg/L, oxygen is added to the remaining samples by aeration.

    Add each bottles change in dissolved oxygen concentration to obtain

    the BOD value.

    Biochemical Oxygen Demand (BOD)

  • Nitrogen Oxidation

    Process of Oxidation:

    Nitrogenous oxygen consumption due to oxidation of nitrogen

    Carbonaceous oxygen consumption due to oxidation of carbon

    Nitrogen Oxidation

    *nitrogen is released as ammonia cation. This cation plus the ammonia

    released by industrial waste is oxidized to nitrate. The nitrate is then

    consumed by a special group of nitrifying bacteria.*

    DO Sag Curve

    DO (dissolved oxygen) determines the health of the river

    DO Sag Curve assess the ability of a river to absorb waste discharge

    *Rivers are able to self-purify itself and as long as DO Curve is group up,

    the river can still manage the waste discharge, but if it goes below the

    critical point, this may cause changes in the living plants or animals in

    the river.*

    DO Sag Curve

    Effects on Nutrient on Water Quality in Rivers

    Nutrients causes excessive plant growth

  • Nutrients are the following:

    Carbon be dissolved in water

    Nitrogen toxic to fish

    element for excessive growth of algae

    Phosphorus vital element for the growth of algae

    Trace elements treated in water facilities

    Effects on Nutrient on Water Quality in Rivers

    *When algae dies, it becomes an oxygen demanding material

    (pollutant).*

    LAKES

    All lakes gradually accumulate silt and organic materials they undergo a

    natural aging process known as EUTROPHICATION.

    OLIGOTROPHIC (few foods) characterized mainly by a low nutrient

    content and low plant productivity

    EUTROPHICATION - excessive addition of inorganic nutrients

    (usually of phosphorous and nitrogen), organic matter, and silt to lakes

    that causes a corresponding increase in biological productivity

  • - when eroded soil and silt from the land enter

    lakes in large quantities, they increase water-column turbidity and

    reduce water depths as these materials accumulate as sediments on the

    lake bottom

    Cultural Eutrophication - caused by human activities ( primarily

    urbanization)

    Natural Eutrophication - inevitable and takes many years to occur

    PROBLEM

    Overuse of Lakes - while aquatic recreational demands increase, the

    amount of the resource stays the samereservoirs and large lakes

    rarely are constructed any more

    SOLUTION

    Time Zoning - some uses are restricted to certain times of the day

    Space Zoning - different areas of the lake are designated for particular

    uses

    PROBLEM

    Exotic Species or Aquatic Nuisance Species (ANS) - such species often are

    better competitors and often drive out native species (include algae,

    plants, fish, and invertebrates)

    SOLUTION

  • ANS Education Programs - aimed at school children will educate the next

    generation of lake users about the dangers of invasive and exotic species

    IN-LAKE MANAGEMENT

    lake management must begin in the watershed, or drainage basin

    dredging can remove accumulations of sediments and their associated

    nutrients

    Fish can be stocked in the lake to create a more balanced fishery

    Water quality assessment

    For the period 2001 to 2005, the EMB monitored a total of 196 inland

    surface waters: 192 rivers and four lakes. Of the 196 monitored water

    bodies, only 127 met the required four sampling events and were

    included in the analysis. Data on the status of water quality contained in

    the EMB National Water Quality Status Report using each of the

    parameters mentioned earlier are presented below.

    Dissolved oxygen (DO)

    Dissolved oxygen (DO) is the amount of oxygen that is dissolved in water

    and is essential to healthy streams and lakes. Dissolved Oxygen is one of

    the water quality parameters used as an indication of how polluted the

    water is and how well the water can support aquatic plant and animal

    life. A higher dissolved oxygen level usually indicates better water

    quality. If dissolved oxygen levels are too low, some fish and other

    organisms may not be able to survive (Stevens Institute of Technology,

    The Global Water Sampling Project 2007).

  • Generally, the national standard for DO is 5 mg/L, except for water

    bodies classified as Class D and Class SD, with standards set at 3 mg/L

    and 2 mg/L, respectively (PEM, 2004).

    Low DO levels may be found in areas where organic material (dead plant

    and animal matter) is decaying, as bacteria require oxygen to

    decompose organic waste, thus, depleting the water of oxygen. Areas

    near sewage discharges sometimes have low DO levels due to this effect

    (Stevens Institute of Technology, The Global Water Sampling Project

    2007).

    Furthermore, low concentrations of DO, when combined with the

    presence of toxic substances may lead to stress responses in aquatic

    ecosystems because the toxicity of certain elements, such as zinc, lead

    and copper, is increased by low concentrations of dissolved oxygen

    (Enderlein et al., 1996).

    The EMB report on monitoring of DO levels shows that approximately 47

    percent of 127 water bodies are found to have good water quality and

    could be tapped as sources for water supply.

    Forty percent recorded fair water quality, which means that the water

    bodies partially comply with the designated water quality criteria but do

    not support its intended beneficial use in 50 to 97.99 percent of

    sampling instances.

    Thirteen percent, however, showed poor water quality. These include

    the four rivers in NCR San Juan River, Paraaque River, Navotas-

    Malabon-Tullahan-Tenejeros River, and Pasig River; Guadalupe River in

    Region VII; Meycauayan and Bocaue Rivers in Region III; and Calapan

    River in Region IV-B.

  • Data in the PEM 2004 issue states, however, that as of 2004, 15 rivers

    nationwide have dissolved-oxygen at or below zero, indicating that they

    are dead during the dry months. In addition, Environment Secretary

    Angelo Reyes also mentioned in a published news article early this year

    (2007) that as many as 50 of the 421 rivers in the country can be

    considered "biologically dead" (Gaylican, C, PDI, 2007).

    Biochemical oxygen demand (BOD)

    Biochemical oxygen demand, or BOD, measures the amount of oxygen

    consumed by microorganisms in decomposing organic matter in stream

    water. BOD parameter measures the organic strength of wastes in water;

    the greater the BOD, the greater the degree of organic pollution.

    BOD also directly affects the amount of dissolved oxygen in rivers and

    streams. The greater the BOD, the more rapidly oxygen is depleted in the

    stream. This means less oxygen is available to higher forms of aquatic

    life. The consequences of high BOD are similar as those for low dissolved

    oxygen: aquatic organisms become stressed, suffocate, and die.

    National standards for BOD vary from 1 to 15 mg/L based on beneficial

    water usage and classification.

    For this parameter, 47 percent of the 107 water bodies with at least four

    sampling events were found to show good water quality, 41 percent have

    fair water quality, while the remaining 12 percent have poor water

    quality with the highest BOD recorded at the downstream section of

    Bulua Creek in Region X. According to the report, this indicates high

    organic discharges from manufacturing facilities, runoff from livestock

    production, and discharges from households.

  • The EMB Report further mentions that there are three rivers that

    recorded zero percent compliance of all samples with the BOD criterion.

    Total suspended solids (TSS)

    TSS parameter measures the amount of undissolved solid particles in

    water such as level of siltation, decaying plant and animal matter, and

    domestic and industrial wastes. For water bodies used for water supply

    the standard for TSS is 25 mg/L for Class AA and 50 mg/L for Class A

    (EMB, 2006).

    Out of forty-six Class A/AA water bodies monitored for TSS, about 23

    percent have good water quality, 69 percent have fair water quality, and

    eight percent have high TSS levels, indicating poor water quality. Among

    those with poor water quality are: Pampanga River in Region III, Bicol

    River in Region V, and Iponan and Alubijid Rivers in Region X.

    According to EMB, the presence of a high percentage of TSS confirms the

    effects of sand and gravel quarrying activities and runoff from denuded

    forests and agricultural lands.

    Total dissolved solids (TDS)

    TDS is generally used as an aggregate indicator of the presence of a

    broad array of chemical contaminants. The primary sources of TDS in

    receiving waters are agricultural runoff, leaching of soil contamination,

    and point source water pollution from industrial or domestic sewage

    (EMB, 2006).

    For water bodies classified as Class AA, the standard for TDS levels is

    expected not to exceed 500 mg/L and 1,000 mg/L for both Class A and D

    waters.

  • Of the 30 monitored Class AA/A water bodies, three have two

    classifications; hence, a total of 33 classifications. About 55 percent have

    good TDS levels, which mean that these water bodies comply with set

    water quality criteria based on their intended beneficial use. Forty-two

    percent have fair TDS levels and only Marilao River has poor water

    quality, with annual average TDS levels ranging from 1,785 to 3,265

    mg/L.

    Heavy metals

    EMB reports that heavy metals are parameters included in monitoring

    activities only for receiving water bodies where mining, electroplating,

    tanning, and other similar activities are operating.

    Among inland surface waters, only Meycauayan, Bocaue, and Marilao

    Rivers have been monitored. Annual average monitoring results of

    Meycauayan River in 2001, 2003, and 2004 show an excess (based on

    minimum criteria and value) for chromium (2001), cadmium (2001),

    and lead (2004) (EMB, 2006).

    Monitoring results of Bocaue River indicate that the River met the

    criteria for chromium, copper, and cadmium. However, it showed high

    lead concentrations in all its sampling stations particularly during the

    dry season in 2004. The Marilao River showed similar excess (relative to

    existing standards) in lead and cadmium in its Class A and C waters.

    Potential sources of heavy metals are tanneries, electroplating, and

    other similar industries located in nearby areas.

  • The Marilao River was the subject of two Greenpeace reports in 1996

    (Lead Overload: Lead Battery Waste Trade and Recycling in the

    Philippines) and, again, in 2003 (Toxics Reloaded: Revisiting the Impacts

    of Lead Battery Waste Trade and Recycling in the Philippines) for lead

    contamination. Effluent samples taken from a discharge canal of the

    Philippine Recyclers, Incorporated (PRI) had lead levels of 190 ppm or

    3,800 times higher than the 0.05 ppm or mg/L standard set for lead in

    effluent from old and existing industries.

    Continuous monitoring of mercury and cyanide levels in rivers and

    creeks traversing Small Scale Mining Areas in some parts of Eastern

    Mindanao is being undertaken by the MGB and EMB. MGB Region XI

    reported in December 2003 that mercury levels were found to be

    beyond the 0.002 mg/L criterion in filtered water samples in some

    monitoring locations in Naboc River. Likewise, cyanide was detected in

    the mixing zone at Sitio Deptro, Upper Ulip (EMB, 2006).

    In October 2005, mine tailings from the operations of Lafayette

    Philippines Inc. spilled into creeks in Rapu Rapu Island causing massive

    fishkills in the receiving marine waters. On July 18, 2006 while on a test

    run that would eventually lead to the full resumption of its operations,

    another fishkill was reported. Greenpeace took samples of water from

    the Mirikpitik Creek in August 2006 and found cadmium, copper and

    zinc levels that were many hundreds of times higher than typical

    background concentrations (Lafayette causes pollution during 30-day

    trial run).

    The PEM 2003, on the other hand, reported that heavy metals and toxic

    pollutants from industrial sources were found to contribute to pollution

    in Metro Manila, Central Luzon, Southern Tagalog, Cebu and mining

    sources in the Cordillera Autonomous Region and CARAGA.

    State of Water Quality

  • Of the 19 rivers being monitored by EMB nationwide, 14 rivers showed

    improvement in BOD and DO level as of 2006 . However, only 8 of the 19

    rivers meet the standards for BOD and DO, namely: Imus river, Mogpog

    river, Malaguit river, Panique river, Anayan river, Iloilo river, Luyang

    river and Sapangdaku river. All the rivers in Metro Manila still exceed

    the criteria for DO/BOD

    Sources of Water Pollution

    Water Quality Management Efforts

  • The EMB and its regional offices continue to intensify its implementation

    of Sagip Ilog Program by closely monitoring the effluents of

    commercial firms and

    industries so that they conscientiously comply with tandards and at the

    same time also undertake river rehabilitation efforts

    In 2007, the EMB issued a total of 2,580 wastewater discharge permits

    and monitored a total of 2,568 firms nationwide. Effluents of those 1,190

    firms which have been identified to be potentially pollutive were tested

    and 308 firms were found to exceed the standards and were issued NOVs

    Legal framework for water governance in the Phils.

    1987 Constitution which mandates that all water resources belong to the

    State;

    Presidential Decree (PD) 1067 in 1976 or The Water Code of the

    Philippines;

    Republic Act (RA) 8041 in 1995 or The Water Crisis Act;

    Executive Order No. 364 in 1996, which created the Presidential Task

    Force on Water Resources Development and Management; and

    Clean Water Act in 2004

  • R.A. 9275 Clean Water Act (CWA) in 2004

    its innovations in water quality management, the Act and its IRR

    require integrated approach, stronger collaboration among

    stakeholders, and promotion of coownership of the water

    bodies.

    ADB warned that water availability in the Philippines could be

    "unsatisfactory" in eight of its 19 major river basins and in most major

    cities before 2025 (ADB, 2007);

    Local governance initiated on water quality management program

    (WQMP) and intervention reforms;

    Major Institutions involved in the Philippine Water Sector

    Policies and Laws on water quality management Program

    Some Local Community Policies and

    Regulations on Water Quality Management Program

    Some Water Quality Management Program

    Implemented by Government.

    Water Quality Management Program

    WQMP emanates from national policies and regulations;

  • Specific enforcement requirements are mandated through enactment of

    ordinances from provincial, municipal, or city governments;

    Programs and activities to control water pollution and protect water

    bodies are spearheaded by various government agencies,

    The Philippine National Standards for Drinking Water of 1993 outlines

    various parameters to be used in the analysis of drinking water quality;

    There are currently 56 bacteriological, physical, chemical, radiological,

    and biological parameters to be monitored.

    Source water and product water are subject to regular monitoring by the

    local health office.

    The national standards for drinking water contains 56 parameters that

    must be complied with.

    Only DOH-accredited laboratories are allowed to conduct water testing

    and analysis. The frequency of monitoring is as follows:

    Bacteriological quality -at least monthly

    Physical quality -at least every six (6) months

    Chemical quality -at least every six (6) months

    Biological quality -at least once a year

    Monitoring of radioactive contaminants shall be done only if there is

    significant input of radiation from the surrounding environment.

  • Parameters monitored (Physicochemical):

    dissolved oxygen (DO),

    biochemical oxygen demand (BOD),

    total suspended solids (TSS),

    total dissolved solids (TDS), and

    heavy metals

    DO, coliform, and heavy metals for coastal and marine waters; and

    biological parameters such as phytoplankton, zooplankton, and benthos

    were monitored in selected water bodies.

    Challenges in WQMP

    Strict Enforcement of Water Policies

    Enhance enforcement capability and capacity to immediately

    address deteriorating water bodies

    Promote compliance to all industries discharging to the Regions water

    bodies

    Strengthening of InterAgency Collaboration

  • Collaborate with other agencies like the Department of Health (DOH),

    Department of Public Works and Highways (DPWH), National Water

    Resources Board (NWRB), and LGUs in implementing WQMP

    Enhancement of Resources and Capabilities of Personnel

    Augment water quality management personnel (Currently, four

    fulltime personnel are incharge of monitoring more than 78,000

    industries and 84 water bodies.)

    Build capacity on water quality management through continuous

    training

    Increase budget allocation to meet the s water quality management

    targets

    Management of Domestic Wastes

    Enhance solid waste management program by providing support to the

    LGUs through capacity building programs

    Sustained Information, Education, and Communication (IEC) Campaign

    by Education Institutions

    Establish disclosure mechanism on water quality management issues

    Develop and publish IEC materials regularly

    Best Practices and Lessons Learned in WQMP

  • River Water Quality Managementcapacitated local farmers in

    understanding and performing water quality monitoring that was

    focused on drinking water quality and its impact to public health (World

    Bank, 2003).

    Lake Water Quality ManagementLaguna Lake is one of Southeast Asias

    largest inland water bodies. Since its establishment in 1966 through RA

    4850, the LLDA has been protecting and preserving the quality of the

    Lake as well as the 21 river systems that flow into it

    Food and WQMP Initiatives at MMSU

    regular food and water quality monitoring to special studies on

    analytical method formulation and/or validation and testing of

    substances to assess impacts on water pollution and food product

    development to help local entrepreneurs.

    initiative is being done to conduct current good manufacturing practices

    (cGMP) on food and water resources for crop production, dormitories,

    faculty houses and water refilling projects for MMSU and for food

    processors of vinegar/wine, local sausage and other local food products

    in the community.

    Implications

  • Clean Water Act of 2004 require appropriate planning processes,

    regulations, capital investments, and resources;

    It is evident that more actions and resources are needed to build on

    existing water quality management programs;

    Organizing Stakeholders

    Conclusion

    Major water quality challenges are felt to improve the quality of its

    surface, ground, and coastal waters;

    The government pursue aggressive strategic plans to address the

    seemingly decreasing trend of the quality of water bodies;

    The active involvement and participation of stakeholders is important in

    implementing WQMP;

    Recommendations

    Successful WQMP requires a strong communitybased effort with

    stakeholder involvement, good partnership building and collaborative

    decision making on best management practices;

    The challenge is to internalize the message that water is an important

    resource and that everyone has to play a role in the conservation and

    management of our water environment;
