Emerging Contaminants

Arsenic concentrations in the waters of Raccoon Creek commonly exceed the New Jersey Surface Water Quality Standard (SWQS) of 0.017. It is currently not known how much of the arsenic measured in streamwater and in bed sediments is contributed by stormwater runoff. Runoff also can contribute trace metals such as cadmium, copper, lead, and zinc, and nutrients to streams; these contaminants typically...

The USGS in cooperation with the USEPA, the Passaic Valley Water Supply Commission (PVWC) and the New Jersey American Water Company initiated a pilot EWS. The objectives of this collaborative effort are to lay the ground work for developing an EWS field site at an operating water utility by deploying an array of water quality sensors to characterize baseline water quality variability at the intake...

As a result of the New Jersey Department of Environmental Protection Toxic Sediment Reduction Program, contaminated sediment in the Lower Passaic River has been identified as being an environmental problem that will require a substantial investment in a clean-up program. To aid in assessing the impact of proposed dredging of contaminated sediments from the Passaic River, the US Geological Survey...

Newark Bay and Hudson River are important port terminals in the northeast United States. These waterways require constant remedial dredging to keep them open for shipping. The sediments in these harbors, however, are known to be contaminated with polychlorinated biphenyl's (PCB's), dioxins/furans, poly-aromatic hydrocarbons (PAH's), metals, and other compounds. In order to reduce future need for...

The U.S. Army Corps of Engineers (USACE) has been tasked by the U.S. Environmental Protection Agency (USEPA) with assessing the economic and technical viability of specific remediation enhancements at the Lipari Landfill Superfund Site (Lipari) located in Mantua Township, NJ. This work includes determining the source of current groundwater contamination in aquifers underlying the landfill and...

Distribution system EWS would, in the most optimal case, detect contamination events quickly and with very low rates of false positive and negative reports. The objectives of this collaborative effort between the EPA/NHSRC.

The goal of this project is to assist EPA in hydrogeologic investigations and perform a groundwater flow assessment in the Pohatcong Valley area to determine probable source of contamination of wells.

The primary threat to water quality and ecologic communities in the DEWA region is residential development. The five counties surrounding DEWA have experienced some of the most rapid residential development in the United States during the past several decades. This project will provide baseline data and an understanding of water-quality in streams entering the Delaware Water Gap NRA.

NAWQA is a program from the USGS that addresses the goals of that status of surface-water and groundwater, provide understanding of human impact, and to support local, state, and federal agencies with aforementioned data.
