Annual Drinking Water Quality Report for 2005
Village of Hamilton Municipal Water System
3 Broad Street, Hamilton, New York
Public Water Supply ID# NY2602377


Introduction
To comply with State regulations, the Village of Hamilton, will be annually issuing a report describing the quality of your drinking water. The purpose of this report is to raise your understanding of drinking water and awareness of the need to protect our drinking water sources. Last year, your tap water met all State drinking water health standards. We are proud to report that our system did not violate a maximum contaminant level or any other water quality standard. This report provides an overview of last year’s water quality. Included are details about where your water comes from, what it contains, and how it compares to State standards.

If you have any questions about this report or concerning your drinking water, please contact Sean Graham, Director of Utilities and Public Works, at 315-824-1111 or Sarah Keith, Water Treatment Plant Operator, at 315-824-2120. We want you to be informed about your drinking water. If you want to learn more, please attend any of our regularly scheduled Municipal Utilities Commission meetings. The meetings are held on the second Tuesday of each month, at 4:00 P.M. at the Village of Hamilton Office Building.

Where does our water come from?
In general, 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 activities. Contaminants that may be present in source water include: microbial contaminants; inorganic contaminants; pesticides and herbicides; organic chemical contaminants; and radioactive contaminants. In order to ensure that tap water is safe to drink, the State and the EPA prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. The State Health Department’s and the FDA’s regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

Our water system serves approximately 4000 people through 873 service connections. Our water source is two drilled wells approximately 53 and 77 feet deep. The water is pumped from the wells and is immediately disinfected with sodium hypochlorite. Prior to being distributed your water is treated with fluoride, which helps fight tooth decay.

New York State Department of Health Source Water Assessment Program Summary:
The NYS DOH has completed a source water assessment for this system, based on available information. Possible and actual threats to this drinking water source were evaluated. The state source water assessment includes a susceptibility rating based on the risk posed by each potential source of contamination and how easily contaminants can move through the subsurface to the wells. The susceptibility rating is an estimate of the potential for contamination of the source water, it does not mean that water delivered to consumers, is or will be contaminated. See section “Are There Contaminants In Our Drinking Water?” for a list of contaminants that have been detected. The source water assessments provide resource managers with additional information for protecting source waters into the future.

The public water supply serving the Village of Hamilton is derived of two drilled wells. The source water assessment has rated these wells as having a medium–high susceptibility rating for industrial contaminants as well as a high susceptibility rating for industrial solvents, nitrates, and microbials. These ratings are due primarily to the close proximity of permitted discharge facilities (industrial/commercial facilities that discharge wastewater into the environment and are regulated by the state and or federal government) to the wells. Based on submitted data, the well field could be prone to flooding. Please note, while the source water assessment rates these wells as being susceptible to microbials, the water is disinfected to ensure that the finished water delivered into your home meets the New York State Drinking Water Standards for microbial contamination.

County and State Health Departments will use this information to direct future source water protection activities. These may include water quality monitoring, resource management, planning and education programs. If you should have any questions or would like to review the Source Water Assessment in our office please feel free to contact the Madison County Department of Health at (315) 366-2526.

Are there contaminants in our drinking water?
As the State regulations require, we routinely test your drinking water for numerous contaminants. These contaminants include: total coliform, turbidity, inorganic compounds, nitrate, nitrite, lead and copper, volatile organic compounds, disinfection by-products, radiological contaminants, and synthetic organic compounds. The table presented below depicts which compounds were detected in your drinking water. The State allows us to test for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representative, are more than one year old.

It should be noted that all drinking water, including bottled drinking water, may be reasonably 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 (800-426-4791) or the Madison County Department of Health Department at 315-366-2526

SEE Enclosed Detected Contaminants Table


Footnotes for Enclosed Detected Contaminants Table
1 – Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of water quality. High turbidity can hinder the effectiveness of disinfectants. Our highest single turbidity measurement for the year occurred on May 27, 2005 and was 0.53 NTU.
2 – The State considers 50 pci/l to be the level of concern for beta particles.
3 – Individuals on a moderately restricted sodium diet should not consume water having levels of sodium greater than 20 mg/l. Individuals on severely restricted sodium diets should not consume water having levels of sodium greater than 270 mg/l.
4 – The lead level presented represents the 90th percentile of the 41 sites. A percentile is a value on a scale of 100 that indicates the percent of a distribution that is equal to or below it. The 90th percentile is equal to or greater than 90% of the lead values detected at your water system. In this case, 41 samples were collected at your water system and the 90th percentile value was the 37th value (6.4 ppb). The action level for lead was exceeded at 1 of the 41 sites tested.
5 – The level presented represents the 90th percentile of the 41 samples collected. The action level for copper was not exceeded at any of the 41 sites tested.

Definitions:
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.
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 do not reflect the benefits of the use of disinfectants to control microbial contamination.
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.
Non-Detects (ND): Laboratory analysis indicates that the constituent is not present.
Nephelometric Turbidity Unit (NTU): A measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.
Milligrams per liter (mg/l): Corresponds to one part of liquid in one million parts of liquid (parts per million - ppm).
Micrograms per liter (ug/l): Corresponds to one part of liquid in one billion parts of liquid (parts per billion - ppb).
Nanograms per liter (ng/l): Corresponds to one part of liquid to one trillion parts of liquid (parts per trillion - ppt).
Picograms per liter (pg/l): Corresponds to one part per of liquid to one quadrillion parts of liquid (parts per quadrillion – ppq).
Picocuries per liter (pCi/L): A measure of the radioactivity in water.
Millirems per year (mrem/yr): A measure of radiation absorbed by the body.
Million Fibers per Liter (MFL): A measure of the presence of asbestos fibers that are longer than 10 micrometers.

What does this information mean?
As you can see by the table, our system had no violations. We have learned through our testing that some contaminants have been detected; however, these contaminants were detected below the level allowed by the State.

Is our water system meeting other rules that govern operations?
During 2005, our system was in compliance with applicable State drinking water operating, monitoring and reporting requirements.

Do I Need to Take Special Precautions?
Although our drinking water met or exceeded state and federal regulations, some people may be more vulnerable to disease causing microorganisms or pathogens 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 from their health care provider about their drinking water. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium, Giardia and other microbial pathogens are available from the Safe Drinking Water Hotline (800-426-4791).

Why Save Water and How to Avoid Wasting It?
Although our system has an adequate amount of water to meet present and future demands, there are a number of reasons why it is important to conserve water:
Saving water saves energy and some of the costs associated with both of these necessities of life;
Saving water reduces the cost of energy required to pump water and the need to construct costly new wells, pumping systems and water towers; and
Saving water lessens the strain on the water system during a dry spell or drought, helping to avoid severe water use restrictions so that essential fire fighting needs are met.
You can play a role in conserving water by becoming conscious of the amount of water your household is using, and by looking for ways to use less whenever you can. It is not hard to conserve water. Conservation tips include:
Automatic dishwashers use 15 gallons for every cycle, regardless of how many dishes are loaded. So get a run for your money and load it to capacity.
Turn off the tap when brushing your teeth.
Check every faucet in your home for leaks. Just a slow drip can waste 15 to 20 gallons a day. Fix it up and you can save almost 6,000 gallons per year.
Check your toilets for leaks by putting a few drops of food coloring in the tank, watch for a few minutes to see if the color shows up in the bowl. It is not uncommon to lose up to 100 gallons a day from one of these otherwise invisible toilet leaks. Fix it and you save more than 30,000 gallons a year.

Closing
Thank you for allowing us to continue to provide your family with quality drinking water this year. In order to maintain a safe and dependable water supply we sometimes need to make improvements that will benefit all of our customers.
