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.

Estimation of Low-flow Statistics for Ungaged Stream Sites on New Jersey Streams
To protect existing water supplies, to plan for future water supplies, and to protect and enhance the aquatic ecology, the NJDEP and USGS, through cooperative agreements, have been developing tools and strategies that can assist in allocating the water resources of the state among competing needs. One such tool is the New Jersey Hydroecological Assessment Tool (NJHAT) that can calculate 171 flow...
Allocation Analysis
Development of water supply is a dynamic condition, and demand areas may shift, or quality or quantity concerns may change in a former study area. This program will address the need of the N.J. Department of Environmental Protection (NJDEP) to understand the possible effects of proposed or planned withdrawals within these previously studied areas. The general objective of this program is to...
EPA biofuels and drinking water supplies
The US EPA Office of Research and Development is carrying out a comprehensive evaluation of the potential impacts on water quality and water supply resulting from the increased use of biofuels. Contamination resulting from releases of biofuel from underground storage tanks may impact ground water that is available for municipal water supply. This concern is greatest for regions of the country that...
Development of Reconstructed Streamflows at Stream Gaging Stations and Ungaged Sites in the Passaic and Hackensack River Basins , Water years 1922-2007, Phase 1
Since 1922, there have been significant human related changes in the Passaic and Hackensack River Basins including significant hydrologic modifications as a result of water supply development and land use changes that impact the runoff characteristics of these watersheds. Since the goal of the NJDEP modeling effort is to determine the safe yield of the major water supply systems under present day...
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...
Water Budget analysis for Water Supply Planning
In the New Jersey Coastal Plain, where confined aquifers provide over 200 million gallons per day, effective water resource planning and management under increasingly complex circumstances requires a current and improving understanding of the limitations of the available water from confined aquifers, the interconnections between confined and unconfined aquifers, and the sources of flow to critical...
Update the NJWaTr database for Years 2000 through 2007
Water Resource planning requires a source of reliable, relevant, easily accessible data. Multiple NJDEP agencies are involved with regulation and data collection with regard to the State's water resources. These programs include land use, water quality, water supply, and wildlife. The USGS NJ WSC has been asked to update the NJWaTr database structure to accommodate new data requirements and to...
NJ Highlands Water Resources Assessment
The water resources assessment of the New Jersey Highlands Region will be accomplished through a comprehensive hydrologic analysis of subwatersheds at the HUC-14 scale. The overall objective of this project is to assist the New Jersey Highlands Council in the development of the Regional Master Plan by providing the hydrologic data and interpretation necessary for a comprehensive assessment of...
Manasquan River Water Budget
The County of Monmouth recently purchased a parcel of land in a rapidly urbanizing area of Monmouth County, New Jersey. The Monmouth County Park System (MCPS) in partnership with the Manasquan River Watershed Association (MRWA) plans to return the land to a more natural state and has received funding from the New Jersey State Wetlands Mitigation Council for a stream restoration project on an...
Streamflow characteristics and the basis for ecological flow goals
The population increase and the associated development have necessitated an increase in the withdrawals of both surface and groundwater to meet water-supply demands, have increased the amount of wastewater discharged from treatment facilities, and have increased the amount of impervious surface area and resulting stormwater flows. Since streamflow can be influenced by both human activities and...
Northeast Water Supply
The NJDEP is conducting a Water Supply Assessment of Northeast NJ and would like the District to help in that assessment, provide modeling tools to project flows, and provide technical assistance. The goals of this project are associated with water supply within the region.
