New Jersey WSC Archived Projects
Results of investigations since the early 1980s by Health Departments of eight counties in southern New Jersey, by the New Jersey Department of Environmental Protection (NJDEP), and by the U.S.Geological Survey (USGS) have determined that mercury concentrations in water tapped by about 500 domestic wells in more than 70 residential areas exceed the maximum contaminant level (MCL) of 2 mg/L. The wells are finished in the areally extensive unconfined Kirkwood-Cohansey aquifer system of New Jersey’s Coastal Plain.
START DATE: 01-JAN-2004
END DATE: 30-SEP-2005
PROJECT NUMBER: 2454BCK
STUDY OBJECTIVES:
- is the source of mercury a diffuse source, as no point sources have been conclusively identified;
- what is the dominant form of mercury at contaminant levels in groundwater;
- what are the processes and (or) mechanisms by which mercury is mobilized; and
- are similar occurrences likely in areas other than New Jersey?
STATEMENT OF PROBLEM:
Results of investigations since the early 1980s by Health Departments of eight counties in southern New Jersey, by the New Jersey Department of Environmental Protection (NJDEP), and by the U.S.Geological Survey (USGS) have determined that mercury concentrations in water tapped by about 500 domestic wells in more than 70 residential areas exceed the maximum contaminant level (MCL) of 2 mg/L. The wells are finished in the areally extensive unconfined Kirkwood-Cohansey aquifer system of New Jersey’s Coastal Plain; background concentrations of mercury in water from this system are less than 10 ng/L.
STRATEGY AND APPROACH:
Data from previous investigations of mercury in various media in New Jersey will be compiled and evaluated, and analyzed statistically.
