Contaminant Fate and Transport Studies in Fractured Sedimentary Rock Aquifers at the former Naval Air Warfare Center (NAWC), West Trenton, N.J.

Contaminants associated with industrial, airport, and other activities are present in groundwater in fractured-rock aquifers, posing long-term hazards to drinking-water supplies and ecosystems. The heterogeneous character of fractured rock challenges our understanding, monitoring, and remediation of such sites.

The New Jersey Water Quality Networks

The water quality of New Jersey's water bodies is monitored by the USGS New Jersey Water Science Center to characterize waters, identify trends over time, identify emerging problems, determine whether pollution control programs are working, help direct pollution control efforts to where they are most needed, and respond to emergencies such as floods and spills.

Long-term Water Monitoring Networks in New Jersey

The accurate, long-term monitoring networks of New Jersey Water Science Center provide valuable data in real-time and historical perspective to compare that data to.  The longer a monitoring location is in operation, the more valuable it becomes, since more statistical comparisons can be...

New Jersey Ambient Surface-Water-Quality Monitoring Network

The USGS New Jersey Water Science Center, in cooperation with the NJ Department of Environmental Protection (NJDEP), New Jersey Water Supply Authority, and the Delaware River Basin Commission, maintain the New Jersey Ambient Surface-Water-Quality Monitoring Network (ASWQMN) — a collection of monitoring stations on streams throughout New Jersey. Constituent concentration data from the ASWQMN...

Emerging Contaminants and their Effects on Fish and Frogs

The endocrine system in animals produce hormones to regulate essential life processes, such as metabolism, tissue function, reproduction, and development. A large group of natural and synthetic chemicals are known to disrupt endocrine function.   Examples include plant hormones, plastic components, flame retardants, surfactants, fragrances, pesticides, etc. Endocrine disrupting chemicals, or...

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).

A Field Method to Quantify Chlorinated Solvent Diffusion, Sorption, Abiotic and Biotic Degradation in Low-Permeability Zones

Strategic Environmental Research and Development Program project ER-2533


In chlorinated-solvent-contaminated fractured-sedimentary-rock aquifers, low-permeability (low-K) strata typically act as long-term or secondary sources of contamination to mobile groundwater in the high-permeability fractures. The fate of dissolved trichloroethene (TCE) in the low-K...
