The Power of Information

National Drinking Water Database

Adirondack Airport Community - Constable, NY

Serves 90 people - Test data available: 2004-2008

This drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group (EWG) by the New York Department of Health- Bureau of Public Water Supply Protection. It is part of EWG's national database that includes 47,667 drinking water utilities and 20 million test results. Water utilities nationwide detected more than 300 pollutants between 2004 and 2009. More than half of these chemicals are unregulated, legal in any amount. Despite this widespread contamination, the federal government invests few resources to protecting rivers, reservoirs, and groundwater from pollution in the first place. The information below summarizes test results for this utility and lists potential health concerns.

This Drinking Water System
National Average
Exceed Health GuidelinesTests showing chemicals at concentrations above health guidelines established by federal and state health agencies. These guidelines are typically set at a levels that pose no significant health risk.
0 chemicals
Health Standard ExceedencesChemicals detected at concentrations above the legal limit, the Maximum Contaminant Level (MCLs) established by the U.S. EPA. Most MCLs are based on annual averages, so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance.
0 chemicals
Pollutants FoundThe total number of contaminants detected since 2004, according to data provided by the state water agency.
6 chemicals
Tests ConductedThe total number of number of water quality tests conducted by water utilities and recorded in data provided by the state water agency.

Testing History

-Tested      -Detected      -Over Health Guidelines      -Over Legal Limit*
NitrateNitrate enters drinking water sources from fertilizer runoff, leaching septic tanks, and erosion of natural deposits; it is also emitted by chemical, petrochemical and metal-finishing industries.1.44 ppm
1.6 ppm
10 ppm
10 ppm
DichlorodifluoromethaneDichlorodifluoromethane (Freon 12) is a chlorofluorocarbon refrigerant and aerosol spray propellant; it was banned under the Montreal Protocol as of 2000 because of its ozone-depleting properties.1.48 ppb
1.7 ppb
1000 ppb
Legal at any levelThis is the Federal Limit. State Limits may be lower.
MTBEMTBE (methyl tert-butyl ether) is a fuel additive that had been used as an octane enhancer in unleaded gasoline; it contaminates groundwater due to spillage or leakage at gas stations, and has been banned or scheduled for phaseout in most states.1.2 ppb
1.6 ppb
13 ppb
Legal at any levelThis is the Federal Limit. State Limits may be lower.
Barium (total)Barium is a mineral that enters drinking water through drilling and mining waste runoff, discharges from chemical industries and erosion of natural deposits.22 ppb
23 ppb
700 ppb
2000 ppb
CyanideCyanide is a chemical used in mining and steel/metal, plastic, and pesticide manufacturing; it is applied to roads as road salts, and small quantities occur naturally in some plants.1 ppb
2 ppb
80 ppb
200 ppb
Methyl ethyl ketoneMethyl ethyl ketone is a synthetic chemical used as a solvent for paints, coatings, adhesives, printing inks, and other industrial and consumer goods; it occurs naturally in some vegetation and forms during ozonation of drinking water. 10 ppb
10 ppb
4000 ppb
Legal at any levelThis is the Federal Limit. State Limits may be lower.
NOTE: Each dot in the above graph represents one month.
* Water utilities are noted as exceeding the legal limit if any test is above the maximum contaminant level (MCL). Most MCLs are based on annual averages so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance.

EPA Violation Summary

Violation CategoryNumber of Violations
(click see violations)

Information on violations is drawn directly from EPA's national violations database in the Agency's Safe Drinking Water Information System. Analyses by others have raised questions about the quality of the information in EPA's database. For the purposes of this investigation, EWG is not showing below or including in our analyses, those violations for individual water suppliers that occurred on days for which the total number of violations assigned by EPA to that water supplier was greater than 20. This criteria was based on common characteristics of incorrect violations data as identified by water utilities, from a review of EPA's violations data by several hundred utilities prior to the release of EWG's investigation.
