Groundwater

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 data collected under the PWTA Program represents the most extensive body of analytical results collected from private wells in New Jersey. Increasing demands for the analysis of this data, from both a public health perspective and as a tool for evaluating the groundwater quality of sources supplying small domestic wells, require the DEP to restructure the existing data system.

The USEPA wants USGS to evaluate available hydrogeologic and groundwater-quality data to determine if there is sufficient data to develop a model to estimate contributing area of water to the wells. The goals of this project are to determine if available data is sufficient to develop a groundwater flow model to estimate contributing area of water to wells and to determine what data needs to be...

Radium is a radioactive element that can have negative effects on humans upon consumption. The research objectives are designed to obtain information regarding the fate of Ra from entry into the water well through passage through the treatment system and ultimate disposal.

Results of investigations since the early 1980s by Health Departments of eight counties in southern New Jersey, by the New Jersey Department of Environmental Protection (NJDEP), and by the U.S.Geological Survey (USGS) have determined that mercury concentrations in water tapped by about 500 domestic wells in more than 70 residential areas exceed the maximum contaminant level (MCL) of 2 mg/L. The...

Groundwater withdrawals in the New Jersey (NJ) Coastal Plain, as well as other parts of the Northern Atlantic Coastal Plain, have increased significantly with the increase in population in recent decades. Future water-supply demands will cause a continuing increase in groundwater withdrawals. The objective of this study is to determine the relationship between changes in base-flow and groundwater...

A new Federal statute adopted by the New Jersey Department of Environmental Protection (NJDEP) concerning Source Water Assessment Program requires NJDEP to conduct assessments on the vulnerability of public supply wells (community and noncommunity) and surface water intakes to 84 contaminants of concern. These contaminants include pathogens, inorganics, nutrients, pesticides, volatile organic...

The problem of fecal coliform bacterial contamination in an anti-degradation stream requires characterization of possible source, additional contaminants, and the potential rate of mobility. This synoptic study will investigate water quality from an additional surface water site and up to 7 groundwater sites in addition to ongoing fixed-station surface-water monitoring during selected seasonal...

This project will provide demonstration and validation of the RCDM diffusion sampler for monitoring groundwater at DoD sites.

The widespread occurrence of naturally occurring radionuclides in principal aquifers of New Jersey and the considerable reliance of the dense population on groundwater resources for drinking water have made extensive research necessary to define the aquifers or portions of aquifers most vulnerable to such contamination. The project will consist of three phases to be completed cooperatively between...

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.

Competition for new water allocations and efforts to protect existing diversion rights have become contentious issued in the Ramapo River Basin.
