Arsenic in New Jersey Well Water

Naturally occurring arsenic may be found in well water in some parts of Hunterdon County, in NJ.

 
Arsenic occurs naturally in soil and bedrock in many parts of the country. It is a toxic element and is a known human carcinogen, proven to increase the risk of adverse health effects in people who drink water containing it. The major exposure is from drinking and cooking. There may also be some exposure during bathing, showering, brushing teeth, etc.
Hunterdon County, New Jersey is one of these areas. Residents using well water, especially in Alexandria Township, Kingwood Township, and Pittstown need to be aware of the health risks caused by arsenic groundwater contamination and their remediation options.
Research by the NJ Geological Survey (NJGS) indicates that arsenic in New Jersey well water is predominately naturally occurring.  This is due to natural rock formations that contain large reservoirs of this element.
Well water tested in these areas frequently exceeds the state of New Jersey’s recommended limits. As a result, when Arsenic 3 and Arsenic 5 contamination is found, remediation is needed. Arsenic does not degrade in groundwater, has no smell or taste, so your well water must be tested to determine levels of arsenic and other elements and the need for remediation.
