Major aquifers in New Jersey

The Coastal Plain is the largest physiographic province in New Jersey. It lies southeast of the Fall Line, where it intersects the Piedmont province in a series of falls along river courses. The geology of the Coastal Plain is characterized by unconsolidated sand, gravel, silt, and clay thickening seaward from a featheredge at the Fall Line to more than 6,500 feet (ft) thick in southern Cape...

Flood Characteristics of New Jersey Streams - Proposal

Federal, state and local agencies need flood-peak data for zoning, building permitting, and flood protection. Flood data needed are high-water elevations, flood discharges, and flood-frequency information. Stankowski in 1974 developed equations relating peak discharge to basin characteristics. Forty-six percent more station years of flood data are now available for analysis. Much of the...

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.

Mercury Processes in Groundwater

Results of investigations since the early 1980s by Health Departments of eight counties in southern New Jersey, by the New Jersey Department of Environmental Protection (NJDEP), and by the U.S.Geological Survey (USGS) have determined that mercury concentrations in water tapped by about 500 domestic wells in more than 70 residential areas exceed the maximum contaminant level (MCL) of 2 mg/L....

Critical area analysis

The development of groundwater in the New Jersey Coastal Plain has occurred primarily near large population centers, creating large regional cones of depression in several of the New Jersey Coastal Plain aquifers. Continued decline of water levels in the confined aquifers poses the threat of serious adverse effects to the water supply in some areas, including the depletion of groundwater...

Coastal Plain Aquifer Synoptic - Chloride Network

Chloride concentrations in groundwater are measured in select wells on a 5-year cycle, as an early warning indicator of saltwater intrusion, and for the definition of the 250 mg/L chloride concentration line within the principal aquifers of the New Jersey Coastal Plain.

Long Island-New Jersey (LINJ) Coastal Drainages Study Overview

The mission of the U.S. Geological Survey (USGS) is to assess the quantity and quality of the earth resources of the Nation and to provide information that will assist resource managers and policymakers at Federal, State, and local levels in making sound decisions. Assessment of water-quality conditions and trends is an important part of this overall mission.

Long Island-New Jersey (LINJ) Coastal Drainages Study

The Long Island-New Jersey (LINJ) coastal drainages NAWQA study is one of the 1994 set and is coordinated from our West Trenton, NJ office. Tasks for the first two years, 1994-95, included staffing, developing a liaison process, analyzing existing data, and designing a data collection program that started in 1996. These planning activities lead to the study design for 3 years of intensive data...

Investigation of Groundwater Conditions and Related Potential Threats to Water Supply and Surface-Water Resources in the Atlantic Coastal Watersheds of South-Central New Jersey

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...

Coastal Plain Aquifer Synoptic

Groundwater withdrawals from the Coastal Plain aquifers of New Jersey have increased steadily since 1900. Because water levels are directly a function of groundwater withdrawals a need exists for the evaluation of potentiometric surfaces with respect to the distribution of water use.

Investigations and Technical Assistance to the Joint Base McGuire-Dix-Lakehurst, New Jersey, in Assessing the Distribution and Transport of Perfluorinated Compounds in Groundwater and Surface Water

The USGS New Jersey Water Science Center is providing technical hydrologic assistance to the U.S. Air Force Civil Engineer Center (AFCEC) at Joint Base McGuire-Dix-Lakehurst (JBMDL) in New Jersey, regarding contamination issues associated with perfluorinated compounds, such as perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and other perfluoroalkyl substances (PFAS) in...

Water Levels in the Ten Major Confined Aquifers of the New Jersey Coastal Plain

The Coastal Plain aquifers of New Jersey provide an important source of water for more than 3.5 million people. The USGS, in cooperation with the New Jersey Department of Environmental Protection, has been measuring water levels in the confined aquifers of the New Jersey Coastal Plain every five years beginning in 1978.  Persistent, regionally extensive cones of depression are present in Ocean...
