Groundwater Surface Water Interactions

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...

Effective management of the Lake Hopatcong watershed requires a basic understanding of a water budget. This was done by measuring outflow by gaging outflow, measuring inflows by collecting discharge measurements at selected inflows and precipitation, and measuring areas of GW inflow and outflow by comparing groundwater level to lake stage

Use of the potable and ecological water supply of Cape May County has exceeded the safe yield of the groundwater and surface water in an undesirable number of areas of peninsular Cape May. Depressed water levels and salt-water supply has significantly withdrawal, and anthropogenic contamination of the groundwater supply has significantly reduced the long-term viability of the supply. The goal of...

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

Anticipated growth in the coastal watersheds of Ocean County, New Jersey has heightened concerns about the future availability of water supply and potential effects of human activities on fluvial and estuarine resources. The overall objectives for the project are to develop an improved hydrologic database and analytical tools for resource management and to apply these tools to improve the present...

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...

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...

The research site is located approximately 15 miles northwest of Atlantic City, New Jersey.
