Indicator Profile of Arsenic in Private Wells

Why Is This Important?

Arsenic is a naturally-occurring element in the earth's crust, and trace amounts can be found in geologic formations and aquifers in parts of New Jersey. Arsenic may also be found in soils as a result of past use of arsenic-containing pesticides and wood preservatives.

Arsenic has been classified by the U.S. Environmental Protection Agency (USEPA) as a known human carcinogen. Ingestion of large amounts of inorganic arsenic is associated with increased risk of several types of cancer, including skin, lung, liver, kidney and urinary bladder. Other potential effects of ingesting large amounts of arsenic include diarrhea, thickening and/or discoloration of the skin, diabetes, and heart disease.
