Determining Loads of Sediment and Chemicals-of-Concern at the Dundee Dam, Passaic River, Patterson, New Jersey
The NY/NJ CARP program attempted to determine the loads of dissolved and sediment bound contaminants of concern that entered the Newark Bay through the Passaic and Hackensack Rivers. Towards this goal, a sampling station was established on the Passaic River at the Passaic Valley Water Commission Plant located at Little Falls, NJ. The USGS recently proposed to the USEPA a sampling program to...
So. New Jersey Radionuclides Septic System Interactions
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.
Passaic River Basin Flow Model
NJDEP, in cooperation with the Passaic TMDL Work Group, has determined that riverine water quality modeling of phosphorus and nitrogen in the Passaic River basin will be required to support several TMDL efforts underway. Water quality in the Passaic River basin is affected by complex river system hydraulics, groundwater-surface water interactions, non-point source runoff from mixed land uses and...
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 in Galloway Township, New Jersey.
Toxics Hydrology Program - Unsaturated Zone Processes and Shallow Groundwater Quality
The Unsaturated Zone is a critical, yet poorly-understood part of the hydrologic cycle. Although it controls the flux of water and chemicals between land surface and the water table, the data necessary to evaluate transport, storage, and reactions occurring within the unsaturated zone are not routinely collected. The unsaturated zone, although often considered a black box, is a fundamental part of...
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 computer systems, including mainframe and personal computers, with only minor...
