Identification of Perfluorinated Carboxylic Acids (PFCAs) in the Metedeconk River Watershed: Research Project Summary

In a 2009 statewide study of perfluoroalkyl compound (PFC) occurrence in public water supplies conducted by NJDEP, the concentration of the PFC compound perfluorooctanoic acid (PFOA) was higher in a drinking water intake along the South Branch Metedeconk River in Ocean County than in the other raw surface water sources tested. The Brick Township Municipal Utilities Authority (BTMUA), which relies on the Metedeconk River as its primary source of water supply, subsequently initiated a PFC source track down study in collaboration with the NJDEP Division of Science, Research, and Environmental Health. The data collected from a series of sampling events show that low levels of various PFCs are present in the study area and likely originate from a number of sources. However, BTMUA documented a localized area of high-level PFC contamination along the South Branch Metedeconk River in Lakewood Township. A groundwater contamination plume emanating from an industrial park on the south side of the river is suspected to be the principle source of PFCs observed in the Metedeconk River and the BTMUA intake samples. Groundwater PFOA levels were found to be as high as 70,000 ng/L in this area. While various PFCs were detected in water samples throughout the study area, and particularly in groundwater samples, PFOA is the primary contaminant of concern with respect to South Branch Metedeconk River water quality and the BTMUA water supply.

Northern New Jersey Radionuclide Investigation: Determination of Uranium, Radium and Radon in Ground Water with High Gross Alpha-Particle Activity, and Implications for Future Monitoring Efforts: Research Project Summary
(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Technology, 2008-03) Louis, Judy; Szabo, Zoltan; Spayd, Steven; Serfes, Mike; Carter, Gail
While a great deal is known about radioactivity in southern New Jersey ground water, the amounts of radioactivity in the ground water in Northern New Jersey ground water are not as well defined. The purpose of this study was to evaluate the presence of gross alpha, radium, uranium, and radon in ground water in the Highlands Physiographic Province. A total of 31 wells were targeted for sampling. The wells selected were known to have high levels of gross alpha-particle activity or were near wells that had previously been shown to have radiological problems.The ground water samples from the targeted wells were collected between June, 2007 and November, 2007.
A Reconnaissance of Contaminants of Emerging Concern in Wastewater and Sludge from Three Publicly Owned Treatment Works in New Jersey
(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Environmental Health, 2018-04-24) Louis, Judy; Lippincott, R. Lee; Goodrow, Sandra M.; Procopio, Nicholas
The character of wastewater, landfill leachate, and sludge taken from three New Jersey regions (Areas) has been assessed for multiple contaminants of emerging concern to determine the likelihood of occurrence in various types of developed areas. Regions were determined based on land use and the projected character of wastewater. The distinct areas of land use that were the aim of this study consisted of residential, commercial, industrial (including two areas with pharmaceutical processing), and hospital/retirement areas. Areas contained various subsewersheds represented by a sampling station that was characterized by the land use type. For example, Area X contained residential sewersheds, industrial sewersheds, and commercial sewersheds. The three Areas contained a total of twenty-six (26) sampling sites, with seventeen (17) of those sites representing various characteristics of the sewershed and the other samples taken of the influent, effluent, and sludge taken from each of the Area’s publicly owned treatment works (POTW). Landfill leachate from one location in each of the three Areas was also analyzed for a suite of compounds.
