Water Availability and Use
Water Availability and Use
Water is vital to the sustainability of human communities, as well as aquatic, riparian, and wetland ecosystems. To aid our understanding of these needs, the NJWSC provides data and analyses of the resources that affect long-term sustainability of water supplies.

Investigation of Potential Threats to Water Supply from the Potomac-Raritan-Magothy Aquifer System in Salem and Eastern Gloucester Counties, New Jersey
Growth in Salem and western Gloucester Counties has spurred interest in additional withdrawal from the PRM. Several deleterious consequences of additional withdrawals are possible. The goals of this project were to determine and estimate additional pumpage from the PRM aquifer, determine the effects of additional pumpage, and determine areas and their associated timeframes of saltwater intrusion.
Development of Field Site To Support Implementation and Testing of Early Warning System
Distribution system EWS would, in the most optimal case, detect contamination events quickly and with very low rates of false positive and negative reports. The objectives of this collaborative effort between the EPA/NHSRC.
Ecologically Relevant Hydrologic Indices for a Baseline Period of Record for Selected Stream Gages in New Jersey
The hydroecological integrity assessment process (HIP) has been fully developed for the State of New Jersey (NJHIP). The New Jersey Department of Environmental Protection is in the process of applying ecologically relevant ecological flow goals (ERHI's) from the NJHIP to current and future regulation of New Jersey streams. It is the goal of NJDEP to evaluate potential impacts of a proposed water...
SWAP Susceptibility Application
As part of the New Jersey Source Water Assessment Program, the U.S. Geological Survey previously developed models to determine the susceptibility of surface water intakes and groundwater supply wells used for public supply. Applying these models presently requires a substantial data-processing effort involving many manual steps. An adaptable, automated process is needed so that NJDEP can update...
Statistics for Statewide Water Capacity Analysis
The New Jersey Department of Environmental Protection (NJDEP) is undertaking an update of the Statewide Water-Supply Master Plan for New Jersey. As part of this process, the water supply planners want to perform an assessment of the potential water capacity of the surficial aquifers of the state. The approach that they envision is to examine the low streamflow statistics for each Hydrologic Unit...
Domestic Well Database
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.
Swartswood Lake
The USGS will collect monthly water quality and quantity data from Neldon's Brook and Indian Brook in support of the Swartswood Lake and Watershed Association's (SWLA) development of a regional storm water management plan (RSWMP).
Development of an Early Warning System for Drinking Water Safety and Security
The USGS will assist in the development of a prototype and multipurpose Early Warning System (EWS) for drinking water safety and security from intentional and accidental spills that utilizes real time monitoring.
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...
Water Budgets and GIS-Based Ground-Water Availability Analysis for the Delaware River Basin
The purpose of this project was to provide a basin-wide vision for long-range goals and provide direction for guiding future water-resource management to the Delaware River Basin Commission (DRBC) for updating its comprehensive plan. A systematic approach was developed for evaluating existing and future water withdrawals relating to available supply and environmental requirements.
Lake Hopatcong Water Budget
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
Future Water Supply for Cape May County
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...
