Raccoon Creek Arsenic

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...

Phase II Trackdown of PCBs and PCDD/Fs in the Elizabeth River, New Jersey

Data collected during Phase I of the NJ Toxics Reduction Workplan for NY-NJ Harbor (NJTRWP) at the Elizabeth River head-of-tide sampling site (and in the downstream tidal Elizabeth River) show elevated levels for contaminants compared to other locations in the harbor. An additional NJTRWP Phase II study was conducted in July/August 2003 in an effort to determine if either of the two minor...

Particulate and Salt Distribution in the Harrison Reach of the Passaic River

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...

Nutrient Monitoring for TMDL's

The Federal Clean Water Act, Sections 303(d) and 305 (b) mandates that states develop a list of water bodies summarizing the state’s water quality and a sub list identifying impaired water bodies for which total maximum daily loads (TMDLs) may be necessary. The USGS will collect, analyze, and publish water quality and streamflow data during 12 events at 19 stream sites (8 in the Saddle River...

New Jersey Toxics Workplan for NY/NJ Harbor Estuary Studies - Toxic

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...

Determining Loads of Sediment and Chemicals-of-Concern at the Dundee Dam, Passaic River, Patterson, New Jersey

The NY/NJ CARP program attempted to determine the loads of dissolved and sediment bound contaminants of concern that entered the Newark Bay through the Passaic and Hackensack Rivers. Towards this goal, a sampling station was established on the Passaic River at the Passaic Valley Water Commission Plant located at Little Falls, NJ. The USGS recently proposed to the USEPA a sampling program to...

Aquifer Flow and Chemistry

Water-quality problems (radium, mercury) in southern NJ in the unconfined Kirkwood-Cohansey aquifer increase needs for high quality water from confined aquifers. The installation of borehole and observation wells throughout Southern NJ provides opportunity to study the chemical evolution of water in both aquifers and confining units.

Hydroacoustics and Technological advancements in Streamgaging

In the mid-1990s, a new technology emerged in the field of streamflow monitoring; the Acoustic Doppler Current Profiler (ADCP). It was originally developed for oceanographic work, but was adapted for inland streamflow measurements. This instrument has been transforming the U.S. Geological Survey (USGS) streamgaging program ever since.

Pesticides and Amphibian Pathogens in Natural and Created Wetlands in the New Jersey Pinelands

The New Jersey Water Science Center in collaboration with the New Jersey Pinelands Commission and Montclair University, conducted a 4 year study to assess the functional equivalency of ponds and stormwater basins in the New Jersey Pinelands by comparing indicators of hydrologic condition, water quality (including pesticides) and biological metrics (amphibian pathogens).

Barnegat Bay Restoration Science

The U.S. Geological Survey (USGS), in cooperation with the New Jersey Department of Environmental Protection (NJDEP) and other partners, is conducting an extensive, coordinated study of physical, chemical, and biological processes in the Barnegat Bay-Little Egg Harbor estuary.  The study integrates findings of teams from the USGS New Jersey Water Science Center and USGS Coastal and Marine...
