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...
DRBC Assistance
USGS will provide technical support to the Delaware River Basin Commission in preparation of the State of the Estuary / State of the Basin Technical reports during calendar years 2010 and 2011.
Cumberland County Ground Water
Ground water is an important source of water supply and has a critical role in maintaining the health of aquatic freshwater and estuarine ecosystems in the Delaware Bay and Atlantic Coastal drainage basins of southeast New Jersey, including the Lower Maurice River and Cohansey Rive. In the coming years, the need for water supply is expected to grow and the priority of maintaining dependent...
Assistance to DODEC Facilities in NJ
The objective of this project is to provide technical support to U.S. Department of Defense (Army, Navy, Air Force). The choice of sites requiring USGS technical assistance will be made in consultation with base/facility personnel.
Penobscot Indian Nation Database
A database was developed by the USGS for the Penobscot Indian Nation (PIN) in 1999 to store water-quality and associated data. A data-entry application in MS Access was also provided. The resulting database and data-entry application are referred to as the Penobscot Indian Nation Environmental (PINE) database. For FY11 the USGS has been requested for development assistance to further improve the...
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...
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...
Refinements of the Data-Collection Workflow and Use of the Penobscot Indian Nation Environmental (Pine) Database
A database was developed by the USGS for the Penobscot Indian Nation (PIN) in 2000 to store water-quality and associated data. A data-entry application in MS Access was also provided. The resulting database and data-entry application are referred to as the Penobscot Indian Nation Environmental (PINE) database.
Pilot for Long Term Daily Hydrograph Development for the Ecological Flow Goals
To use NJHAT at ungaged sites, an analytical tool is required that can develop a long-term daily hydrograph at these sites. The objectives of the project is to pilot the use of TOPMODEL and DHI software to produce long-term hydrographs at gaged sites and to show that one or both of these models could be used to produce long-term hydrographs at ungaged sites with sufficient accuracy for use with...
Hydrogeologic Framework of CDE Superfund Site, South Plainfield, NJ
The US Environmental Protection Agency (USEPA) in cooperation with the US Geological Survey (USGS) has developed a work plan to investigate the hydrogeologic framework of the Cornell-Dubilier Electronics Superfund Site (CDE) in South Plainfield, New Jersey. The objective is to collect and analyze a suite of borehole geophysics data from selected offsite monitoring wells in conjunction with...
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...
