Abstract

The U.S. Geological Survey analyzed trace metal concentrations in tap water from domestic wells in newly constructed homes in Berkeley Township, Ocean County and Galloway Township, Atlantic County, N. J. The potable water distribution systems in all of the homes sampled are constructed primarily of copper with lead-based solder points. Home water treatment is used in Berkeley Township but not in Galloway Township. Tap water was collected after the water had been standing in the pipes overnight. In Berkeley, 6 to 11 samples exceeded both the U.S. Environmental Protection Agency 's primary drinking water regulation (DWR) for lead (50 microgram/L) and the secondary drinking water regulation (SDWR) for copper (1,000 microgram/L). In Galloway, 12 of 14 samples exceeded the DWR for lead and 13 of 14 exceeded the SDWR for copper. After collecting the standing-water samples, the water was left running for 15 minutes and a second sample was collected. None of the running-water samples exceeded the regulations for lead or copper. Available data suggest a correlation between the residence time of soft, acidic groundwater in new home plumbing systems and elevated trace-metal concentrations in drinking water derived from domestic wells within the New Jersey Coastal Plain.
