Analysis of Mercury Species in New Jersey Ground water Using Inductively Coupled Plasma - Mass Spectrometry and Gas Chromatography: Research Project Summary
(Trenton, N.J. : New Jersey Department of Environmental Protection and Energy, Division of Science and Research, 1993-06) Murphy, Eileen A.; Dooley, John; Windom, Herbert L.; Smith, Ralph G. Jr.
Water samples from 78 private potable wells in southern NJ were collected for mercury analysis in 1991-1992. The wells are located in Atlantic, Burlington, Camden, Cape Map and Ocean Counties. Total mercury concentrations varied from 1 ng/L to over 36 Fg/L. The dominant form in which mercury occurred in the wells sampled was inorganic, although monomethylmercury was present in some wells comprising up to 8% of the total mercury in one ground-water sample. Mercury analyses performed using the EPA Method 245.1 should be interpreted with caution. While this method is generally suited for analyzing waters having elevated mercury concentrations (total mercury levels above 2000 ng/L or 2 µg/L), it is less sensitive and even inadequate for characterizing background mercury levels.
Arsenic and Mercury in Residential Well Water from Readington and Raritan Townships, Hunterdon County, New Jersey: Research Project Summary
(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Technology, 2002-07) Murphy, Eileen A.
In October 2000, well water testing for arsenic and mercury was offered to residents living in Readington and Raritan Townships in Hunterdon County, New Jersey. The goal was to generate data on levels of these contaminants in groundwater used for drinking water in the area. Previous testing showed that this part of the state may have potentially elevated levels of arsenic in well water due to leaching from certain arsenic-rich geologic formations. Two hundred thirty-eight wells were sampled. Three quarters of the well water samples contained arsenic levels below 5 μg/L (micrograms per liter). A quarter of the samples were above 5 μg/L, with 3% of wells containing arsenic levels above 10 μg/L. The highest arsenic level observed in this study was 35 μg/L. Few water samples had detectable levels of mercury, and of those where mercury was detected, the levels were trace.

Evaluation of Chemical and Physical Characteristics of Water Treatment Residuals Before and After a Freeze-Thaw Cycle: Research Project Summary
(Trenton, N.J. : Department of Environmental Protection and Energy, Division of Science and Research, 1994-03) Murphy, Eileen A.; Dempsey, Brian; DeWolfe, James; Lunetta, Mark; Elias, Steven
The effects of natural freeze/thawing on the chemical and physical characteristics of eight NJ water treatment residuals were investigated in relation to trace metal leaching. Field and laboratory studies indicate that leaching of metals from residuals which have undergone a freeze/thaw cycle is considerably less than raw residuals. Furthermore, freeze-thawed residuals mixed with NJ soils leached metals less than raw residuals mixed with soils. The freeze/thaw residuals-soil mixtures, in most cases, exhibited leaching characteristics similar to those of the soils alone.
Lead in New Jersey School Drinking Water: Results of a Monitoring Study: Research Project Summary
(Trenton, N.J. : Department of Environmental Protection and Energy, Division of Science and Research, 1993-05) Murphy, Eileen A.
In 1990 and 1991, water samples from 100 drinking water fountains in 50 school buildings were collected and analyzed for lead, copper, hardness, alkalinity, pH, and temperature. Fountains were sampled first thing in the morning, after flushing the fountain for 10 minutes, and just before the first lunch break at the school.
Nitrate in Drinking Water Wells in New Jersey: Burlington, Gloucester, Mercer, Ocean, and Salem Counties: Research Project Summary
(Trenton, N.J. : Department of Environmental Protection and Energy, Division of Science and Research, 1998-03) Murphy, Eileen A.
Drinking water wells throughout Burlington, Gloucester, Mercer, Ocean and Salem Counties, New Jersey were sampled for levels of nitrate during the spring and summer of 1990 and 1991. Highest nitrate concentrations were found in water from shallow wells (less than 100 ft.), within 50 ft. of a septic tank, near land to which fertilizer had been applied, and within 1/4 mile of an agricultural area, sod farm or golf course.

Sources of Lead in Homes Served by Private Wells in Hunterdon County, NJ: Research Project Summary
(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Technology, 2006-11) Murphy, Eileen A.; Hall, Gene
Lead is one of the inorganic constituents required for testing in New Jersey’s Private Well Testing Act. During the first two years of this new law, elevated lead levels in private well water were reported to the state. A study was initiated with researchers at Rutgers University to identify the source(s) of the lead in these private well water samples. The results of this study, conducted in Hunterdon County, indicate that plumbing is responsible for the lead in the water samples. Specifically, plumbing associated with the holding tanks appears to be the primary source of lead in the water samples collected.
