2008 Legler System Annual Drinking Water Quality Report

For water tested in the year 2007

We are pleased to present this year’s Annual Drinking Water Quality Report. This report is designed to inform you about the quality of water and services we deliver. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts made to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. If you are a property owner and have tenants living in Jackson, we ask that you please forward this water quality report to them.

Where does your drinking water come from?

Our source water comes from aquifers deep within the ground. Our primary source of water is located in the middle Raritan formation. Well number 1 is 960 ft. deep and well number 3 is over 1700 ft. deep. These aquifers will provide the Legler water system with an abundant supply of good, clean water for many years to come.

Recent improvements: The Legler water system has recently installed a new pump and motor for well 1.


In the event of a water or wastewater emergency, the Authority can be contacted by telephone 24-hours a day. Please call 732-928-2222 to report an emergency.

Where do contaminants come from?

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:

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

· Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm          water runoff, industrial or domestic wastewater discharges, oil and gas production,mining, or farming.

· Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water          runoff, and residential uses.

· Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of          industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff,          and septic systems.

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


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 provider. EPA / CDC guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants, along with more information about contaminants and potential health effects, can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline at 1-800-426-4791.

In this table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms, we have provided the following definitions.

Parts per million (ppm): or Milligrams per liter (mg/l) One part per million corresponds to one-minute in two years or a single penny in $10,000.

Parts per billion (ppb): or Micrograms per liter (ug/l) One part per billion corresponds to one-minute in 2,000 years or a single penny in $10,000,000.

Picocuries per liter (pCi/L): Picocuries per liter is a measure of the radioactivity in water.

Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

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 (MCLGs): 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.

The state allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently.

Waivers: The Safe Drinking Water Act regulations allow monitoring waivers to reduce or eliminate the monitoring requirements for asbestos, volatile organic chemicals, and synthetic organic chemicals. Our system received monitoring waivers for synthetic organic chemicals in 1995.

The New Jersey Department of Environmental Protection (NJDEP) has completed and issued the Source Water Assessment Report and Summary for this public water system, which is available at or by contacting the NJDEP, Bureau of Safe Drinking Water at 609-292-5550.

Jackson Township MUA - Legler System - PWSID # 1511012

Jackson Township MUA - Legler System is a public community water system consisting of 2 wells, 0 wells under the influence of surface water, 0 surface water intakes, 0 purchased ground water source, and 0 purchased surface water sources.

This system’s source water comes from the following aquifers and/or surface water bodies: lower Potomac-Raritan-Magothy aquifer, upper Potomac-Raritan-Magothy aquifer.

This system purchases water from the following water system(s) (if applicable): None

Susceptibility Ratings for Jackson Township MUA - Legler System Sources

The table below illustrates the susceptibility ratings for the seven-contaminant categories (and radon) for each source in the system. The table provides the number of wells and intakes that rated high (H), medium (M), or low (L) for each contaminant category. For susceptibility ratings of purchased water, refer to the specific water system’s source water assessment report.

The seven-contaminants categories are defined at the bottom of this page. The NJDEP considered all surface water highly susceptible to pathogens; therefore, all intakes received a high rating for the pathogen category. For the purpose of Source Water Assessment Program, radionuclides are more of a concern for ground water than surface water. As a result, surface water intakes’ susceptibility to radionuclides was not determined and they all received a low rating.

If a system is rated highly susceptible for a contaminant category, it does not mean a customer is or will be consuming contaminated water. This rating reflects the potential for contamination of source water, not the existence of contamination. Public water systems are required to monitor for regulated contaminants and to install treatment if any contaminants are detected at frequencies and concentrations above allowable levels. As a result of the assessments, the NJDEP may customize (change existing) monitoring schedules based on the susceptibility ratings.

-Pathogens: Disease-causing organisms such as bacteria and viruses. Common sources are animal and fecal wastes.

-Nutrients: Compounds, minerals and elements that aid growth, that are both naturally occurring, and man-made. Examples include nitrogen and phosphorus.

-Volatile Organic Compounds: Man-made chemicals used as solvents, degreasers, and gasoline components. Examples include benzene, methyl tertiary butyl ether (MTBE), and vinyl chloride.

-Pesticides: Man-made chemicals used to control pests, weeds and fungus. Common sources include land application manufacturing centers of pesticides. Examples include herbicides such as atrazine, and insecticides such as chlordane.

-Inorganics: Mineral based compounds that are both naturally occurring and man-made. Examples include arsenic, asbestos, copper lead, and nitrate.

-Radionuclides: Radioactive substances that are both naturally occurring and man-made. Examples include radium and uranium.

-Radon: Colorless, odorless, cancer-causing gas that occurs naturally in the environment. For more information go to or call (800) 648-0394.

-Disinfection Byproduct Precusors: A common source is naturally occurring organic matter in surface water. Disinfection byproducts are formed when the disinfectants (usually chlorine) used to kill pathogens react with dissolved organic material (for example leaves) present in surface water.


In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

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 EPA’s Safe Drinking Water Hotline at 1-800-426-4791.

As you can see by the table, our system had no violations. We’re proud that your drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some constituents have been detected. The EPA has determined that your water is safe at these levels. In addition to the constituents listed herein, the Authority regularly tests for over 80 additional potential contaminants.

If you have any questions about this report or concerning your water utility, please contact David Harpell, Executive Director at 732-928-2222. We want our valued customers to be informed about their water quality. If you want to learn more, please attend any of our regularly scheduled MUA meetings at the MUA’s administrative office, 135 Manhattan Street. Meetings are held on the fourth Thursday of each month at 5:30 p.m.. You may also visit us on the web at

Special Considerations

Regarding Children, Pregnant Women,

Nursing Mothers, and Others

Children may receive a slightly higher amount of a conta- minant present in the water than do adults, on a body weight basis, because they may drink a greater amount of water per pound of body weight than do adults. For this reason, reproductive or developmental effects are used for calculating a drinking water standard if these effects occur at lower levels than other health effects of concern. If there is insufficient toxicity information for a chemical (for example, lack of data on reproductive or development effects), an extra uncertainty factor may be incorporated into the calculation of the drinking water standard, thus making the standard more stringent, to account for additional uncertainties regarding these effects. In the cases of lead and nitrate, effects on infants and children are health endpoints upon which the standards are based.

Nitrate: Nitrate in drinking water at levels above 10ppm is a health risk for infants of less than six-months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider.

Lead: Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home plumbing. If you are concerned about elevated lead levels in your home water, you may wish to have your water tested and flush your tap for 30-seconds to 2-minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline at 1-800-426-4791.

Secondary Contaminants

Secondary contaminants are characteristics that affect the taste, odor and appearance of drinking water quality. These aesthetic qualities are monitored and reported to the DEP once in each three-year compliance period.

Daily testing is done at each treatment plant to adjust for the proper pH (between 6.5-8.5) and chlorine levels in the finished water supply. Iron and Manganese tests are performed several times each day.
