Water Quality Report - 2003

For the Year 2002

Our goal is to provide you with a safe and dependable supply of drinking water. This report is a snapshot

of the quality of water that we provided for January 1 through December 31, 2002. It also includes the date and results of any contaminants that we detected within the past five years tested less than once a year. Any contaminants detected within the past five years are listed along with the date of detection and concentration. This report is designed to inform you about the quality water and services we deliver to you every day.

Water Source Information

The source of your drinking water is:

Vermont Source Type: Gravel Screened well

EPA Source Type: Groundwater, non-purchased

Source Name: WELL 1

Location:

Vermont Source Type: Gravel Screened well

EPA Source Type: Groundwater, non-purchased

Source Name: WELL 2

Location:

Source Protection Plan: We have a source protection plan available from our office that provides more information such as potential sources of contamination. The Water Supply Division approved our source protection plan on: 7/23/96, and has accepted and recorded subsequent updates.

Our System's susceptibility to potential sources of contamination is: low due to two impeding layers of compacted till and clay that lie between the surface and the zone from which we draw our water.

Sources of Drinking Water and Contaminants

The sources of drinking water (both tap water and bottled water) include surface water (streams, lakes)

and ground water (wells, springs). As water travels over the land's surface or through the ground,

it dissolves naturally-occurring minerals. It also picks up substances resulting from the presence of animals and human activity. Some "contaminants" may be harmful. Others, such as iron and sulfur, are not harmful.

Public water systems treat water to remove contaminants, if any are present.

In order to ensure that your water is safe to drink, we test it regularly according to regulations established

by the U.S. Environmental Protection Agency and the State of Vermont. These regulations limit the

amount of various contaminants:

Microbial organisms (viruses and bacteria) may come from sewage treatment plants,
septic systems, agricultural livestock operations, and wildlife.
Inorganic chemicals (salts and metals) can be naturally-occurring or result from urban
storm water runoff, industrial or domestic wastewater discharges, or farming.
Synthetic Organic chemicals (pesticides and herbicides) may come from agriculture,
urban storm water runoff, residential uses, and careless disposal of household chemicals.
Volatile Organic chemicals (gasoline and solvents) may come from gas stations, urban
storm water runoff, septic systems, industrial process, and careless disposal of household chemicals.
Naturally occurring radioactivity

W A T E R Q U A L I T Y D A T A

The table below lists all the drinking water contaminants that we detected during the 2002 calendar year. It also includes the date and results of any contaminants that we detected within the past five years tested less than once a year. The presence of these contaminants in the water does not necessarily show that the water poses a health risk.

Terms and abbreviations - In this table you may find terms you might not be familiar with. To help you better understand these terms we have provided the following definitions:

· Maximum Contamination 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 Contamination 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.
- Secondary Maximum Contamination Level (SMCL): A secondary MCL is a non-health-related guideline used to assess the aesthetic qualities of water such as taste, odor, and color.
- 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 disinfectants in controlling microbial contaminants.
- Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in
  drinking water. Addition a disinfectant may help control microbial contaminants.
- Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other
  requirements which a water system must follow.
- 90^th Percentile: Ninety percent of the samples are below the action level. (Nine of ten sites sampled were
  at or below this level).
· Treatment Technique(TT): A process aimed to reduce the level of a contaminant in drinking water.
Parts per million (ppm) or Milligrams per liter (mg/l): (one penny in ten thousand dollars)
Parts per billion (ppb) or Micrograms per liter (lg/l): (one penny in ten million dollars)
Picocuries per liter(pCi/L): a measure of radioactivity in water

Violation(s) that occurred during the year

We had no violations occur during the year of 2002

Additional information

We maintain chlorine at approximately 0.2 ppm as a health precaution.

Manganese exceeds the SMCL. We add polyphosphate to sequester excess manganese.

We have increased the frequency of site inspections and are taking other action to further improve security.

We add fluoride to our water supply to promote public health through the prevention of tooth decay.

Health information regarding drinking water

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/CDC guidelines on appropriate means to lessen the

risk of infection by cryptosporidium and other microbiological contaminants are available from EPA's

Safe Drinking Water Hotline (1-800-426-4791).

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 the water

poses a health risk. More information about contaminants and potential health effects can be obtained by

calling the Safe Drinking Water Hotline.
