TRENTON – Tainted groundwater poses risks to some private-well residences near a Superfund site in Warren County, the state has reported.
According to an assessment by the state Health and Senior Services Department, exposure to such chemicals as PCE and TCE at the Valley Groundwater Contamination site in Warren poses a risk to people who get their water from wells that lack filtration systems.
The Department said it is not a public health concern if the drinking water comes from either a public water supply or from private wells that have filtration systems.
However, there are health concerns relating to PCE (tetrachloroethylene) and TCE (trichloroethylene) exposure from private wells without filters, the Department said.
In the late 1970s, assessments of groundwater from two public water supply wells within the Pohatcong Valley found that the regional groundwater was contaminated with PCE and TCE, stemming from industrial facilities and commercial businesses operating within Washington Borough, the Department reported.
Investigations from 1984 through 2010 by the Warren County Health Department, the New Jersey Department of Environmental Protection and the federal Environmental Protection Agency indicated that domestic groundwater wells for a number of residences had PCE and/or TCE levels above the state drinking water standards.
