Coastal Plain Aquifer Synoptic - Chloride Network

Chloride concentrations in groundwater are measured in select wells on a 5-year cycle, as an early warning indicator of saltwater intrusion, and for the definition of the 250 mg/L chloride concentration line within the principal aquifers of the New Jersey Coastal Plain.

Region 1: North Atlantic-Appalachian PFAS Capability Team

Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic emerging contaminants. Some PFAS have been voluntarily phased out, as exposure has been linked to adverse human health effects.

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.

Coastal Plain Aquifer Synoptic

Groundwater withdrawals from the Coastal Plain aquifers of New Jersey have increased steadily since 1900. Because water levels are directly a function of groundwater withdrawals a need exists for the evaluation of potentiometric surfaces with respect to the distribution of water use.

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...

Point and Nonpoint Sources of Endocrine Disrupting Compounds and the Potential effects on Fish and Frogs in the New Jersey Pinelands

Scientists from the NJ WSC, Leetown Science Center and New Jersey Pinelands Commission recently initiated a 4 year study designed to characterize the point and non-point sources of endocrine disrupting compound (EDCs) and their potential effects on fish and frogs in the NJ Pinelands.
