Mercury Processes in GW
Project Title: Mercury Processes in GW
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.
