To comply with State regulations the Development Authority of the North Country 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, we conducted tests for total coliform, total trihalomethanes and haloacetic acids. 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 The Development Authority of the North Country, 661-3210. We want you to be informed about your drinking water.


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 the Villages of Chaumont, Dexter and Brownville, the Towns of Cape Vincent, Lyme and Brownville and the General Brown School. Our water source is the Saint Lawrence River. Attached is a copy of the Annual Water Quality Report as supplied by the Village of Cape Vincent. The Village of Cape Vincent supplies water to the Town of Cape Vincent’s water storage tank. Located in the Town of Cape Vincent’s Pump Station are two 100 horsepower pumps, which pump water through a 12-inch ductile iron pipeline to the Limenck Pump Station. At that point a 10-inch ductile iron pipeline continues to the Village of Brownville. The water is rechlorinated as it leaves both the Town of Cape Vincent and Limerick Pump Stations prior to distribution.


As the State regulations require, we routinely test your drinking water for numerous contaminants. These contaminants include: total coliform, total trihalomethanes and haloacetic acids. It should be noted that all drinking water, including bottled drinking waters 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 New York State Health Department at 785-2277.

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,

Milligrams per liter (mg/l): Corresponds to one part of liquid in one million parts of liquid (parts per million ppm).

Micrograms per liter (112/1): Corresponds to one part of liquid in one billion parts of liquid (parts per billion – ppb).


We have learned through our testing that some contaminants have been detected; however, these contaminants were detected below the level allowed by the State.
