Surface Water
Surface Water
Streams, rivers, lakes and reservoirs - collectively referred to as surface water - are important natural resources. The NJWSC provides unbiased, timely, and relevant information, studies, and data about water resources of New Jersey.

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...
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...
Hydrologic Changes Winslow Township
The Kirkwood-Cohansey aquifer system underlies Winslow Township. Under natural conditions, water from the Kirkwood-Cohansey discharges to the perennial streams of the Great Egg Harbor River basin. This is referred to as the baseflow of the stream. Withdrawals by wells from the Kirkwood-Cohansey intercept ground water that would have discharged to a stream. In addition, if withdrawals are of...
Background Metals in Surface Water
Results of water-quality sampling in tributaries and major rivers of New Jersey have revealed that arsenic levels that exceed the human-health-based Surface Water Quality Standard (SWQS) are widespread. Exceedances of the mercury SWQS are prevalent, although less widespread than arsenic exceedances.
Stormwater Runoff TMDL for Aquatic Life
Biological impairment is but an indicator that some type of anthropogenic process has occurred resulting in aquatic assemblage degradation. The purpose of this proposal is to establish an applicable TMDL approach to address aquatic life impairments associated with stormwater runoff and hydrologic alteration for streams in New Jersey with the goal of improving river systems by reducing the impact...
Pinelands Kirkwood-Cohansey
The study examines the structure and function of the hydrologic system supporting Pinelands aquatic and wetland communities and the hydrologic and ecological response to groundwater-withdrawal stress. USGS components of the study focus on various aspects of the hydrologic system that controls groundwater and surface-water flow, depth of water in wetlands, and interactions between the groundwater...
Determination of Total Annual Nonpoint Source Pollution Loads to selected River Systems in New Jersey
Elevated levels of bacteria, nutrients, and suspended sediments exceeding MCLs is of concern for a number of New Jersey streams. Uncontrolled, non-point (NPS) pollution from increasing commercial and residential land development throughout the State is of special concern. For effective placement of appropriate best management practices (BMPs) and the establishment of TMDLs, water-resource managers...
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...
Incorporation Of Detailed, New Jersey Specific Hydrologic Information Into The Wetland Construction And Mitigation Planning Process - Develop work plan to design manual that incorporates NJ specific hydrologic information
The NJDEP is responsible for the review of proposals for wetlands mitigation and restoration submitted to the Wetland Mitigation Council. They have expressed concern that the failure of various wetland mitigation projects may be a result of problems with the hydrology of the sites. The goal of this project is to Assess the extent of hydrologic data and information that are used in typical wetland...
Evaluation of the changes in hydrology and ground- and surface-water quality in an urban wetlands as part of a wetlands restoration effort
Wetlands restoration projects have often been unsuccessful because the effects of changes in the hydrology and water quality on plant communities are poorly understood. The overall goal of the project is to evaluate the effects of the modification of the flow regime in an urban wetlands area on the hydrogeology, water quality, soil characteristics, and plant communities over a thee-year period...
Data Model of Stream Flows: Baseline Identification & Analysis for the Ecological Flow Goals
The recent 4-year joint USGS/NJDEP research project 'Ecological Flow Goals' has resulted in the New Jersey Hydrologic Assessment Tool (NJHAT). This analysis software determines streamflow characteristics and variability based on a daily hydrograph. The objectives of the project is to identify a series of baseline hydrographs for surface water gaging stations with greater than 20 years of flow...
Delaware Water Gap NPS
The primary threat to water quality and ecologic communities in the DEWA region is residential development. The five counties surrounding DEWA have experienced some of the most rapid residential development in the United States during the past several decades. This project will provide baseline data and an understanding of water-quality in streams entering the Delaware Water Gap NRA.
