Radiochemistry

Groundwater is the sole source of water supply for many people in New Jersey. Large-scale groundwater pumpage, installation of sanitary- and storm-sewer systems, and frequent variations in precipitation all have significant effects on regional groundwater levels and aquifer storage. To properly manage this resource, a consistent dataset of hydrologic data available for water managers and scientist...

Elevated gross alpha-particle activity in groundwater has recently been documented from scattered areas in northern New Jersey. Initial data compilations indicate most of this alpha-particle activity is attributable to long-lived isotopes of U, and to a lesser extent, the long-lived progeny, Ra-226. The project will consist of three phases to be completed cooperatively between the USGS and NJDEP...

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.

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.
