Galloway Mathematical Models

The Galloway research team has developed and documented three computer programs for simulating flow and transport in the unsaturated zone that are available to the public.  These programs were funded by the Toxics Substances Hydrology Program. The computer codes are written in Fortran F77 and run on a variety of...

USGS assistance to USEPA on the remedial investigation and feasibility study of the Puchack well field Superfund site, Pennsauken, New Jersey

Puchak well field is located in Pennsauken Township, an area with significant pumpage from the Potomac-Raritan-Magothy aquifer system well fields owned by the City of Camden Water Department and the Merchantville-Pennsauken Water Commission. Ground water contamination from a chromium plume affecting the wells at the Puchak well field resulted in termination of the use of the well field for...

Unregulated Contaminants in WWTPs

Although the occurrence of OWCs in streams can be related in part to discharges from WWTPs it is uncertain whether the sources of these compounds are domestic waste, or waste from manufacturing or other commercial processes. Furthermore, it is unclear if different treatment processes may be more effective at removing OWCs than others. The primary objective of the study is to perform a...

Source Water Assessment for Program -- Vulnerability of Public Supply Wells and Surface Water Intakes in New Jersey to Chemicals of Concern

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...

SERDP project - VOC

Few studies have evaluated or compared contaminant mass removal by Pump-and-Treat (P&T), Monitored Natural Attenuation (MNA), or Enhanced Biodegradation (EB) in fractured-rock aquifers, partly because of the perceived hydrogeologic complexity, the lack of understanding of the processes controlling the migration and transformation of contaminants, and the lack of sufficient field data for...

Removal of Unregulated Organic Chemicals (UOC's) in Water Treatment Processes

Numerous organic chemicals are used every day for industrial, commercial and household purposes. Recent investigations have indicated that a number of these chemicals have found their way into many of the nation’s wastewater treatment facilities, receiving waters, aquifers and drinking water treatment facilities. This project will evaluate a variety of treatment processes (different design and...

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...

Processes Affecting the Natural Attenuation of Gasoline in Ground Water -- Galloway Township, New Jersey

Gasoline spills from leaking underground storage tanks is the most common mechanism of subsurface point source contamination. The U.S. Geological Survey's Toxic Substances Hydrology Program investigated the fate and transport of hydrocarbons in the unsaturated zone and shallow groundwater at a gasoline-spill site...

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...
