What percentage of tests exceeded a level that could cause health effects?
Middle Island New York Residents: Based On Recent Testing, Here Are The Results:
1,4-dioxane Suspected Carcinogen:
Possible carcinogen that attacks the nasal cavity, kidney and liver. A clear liquid that dissolves in water and is used primarily as a manufacturing solvent, although it can also be found in personal care items such as soap. Of 1,062 tests nationwide that exceeded the level, 221, or 20 percent, were on Long Island. Prolonged exposure above the level could lead to one additional cancer case per 1
1,2,3-trichloropropane Volatile Organic Compound:
Used as an ingredient in paint, varnish remover, solvents and degreasing agents. Prolonged exposure above the level could lead to one additional cancer case per 1 million population.
PFOS Perfluorinated Chemicals:
Surfactant or emulsifier; used in fire-fighting foam, circuit board etching acids, alkaline cleaners, floor polish, and as a pesticide active ingredient for insect bait traps; U.S. manufacture of PFOS phased out in 2002; however, PFOS still generated incidentally. Prolonged exposure above the level could lead to adverse health effects
Chlorate Toxic Substance:
Can cause anemia and nervous system problems in children. Used as a disinfectant, it prevents the body from absorbing iodine, important to the normal functioning of the thyroid gland. Prolonged exposure above the level could lead to adverse health effects.
PFHxS Perfluorinated Chemicals:
11.5% 3 out of 26 samples Manmade chemical; used in products to make them stain, grease, heat and water resistant
PFHpA Perfluorinated Chemicals:
7.7% 2 out of 26 samples Manmade chemical; used in products to make them stain, grease, heat and water resistant
Hexavalent chromium Toxic Substance:
Used in chrome-plating, dyes, pigments, tanning leather and preserving wood, if inhaled it can cause lung cancer, stomach tumors and skin ulcers. The government is reviewing its toxicity in drinking water and has set no threshold for dangerous exposure. It was detected in 1,247 of 1,417 tests on Long Island.
HCFC-22 Volatile Organic Compound:
Used as a refrigerant, as a low-temperature solvent, and in fluorocarbon resins, especially tetrafluoroethylene polymers. It is chlorofluorocarbon and occurs as a gas.
