From abstract: This report describes a study of coastal processes along the Atlantic Coast from Sea Bright to Ocean Township, New Jersey. Predictive tools were developed and a data analysis made to assist in evaluation and implementation of comprehensive shore protection plans for this highly utilized stretch of coastline.
This report describes the results of a computer model simulation of the Potomac-Raritan-Magothy aquifer system in New Jersey to see "the effects of supplementing ground water from the Delaware River. It includes tables.
From abstract: A digital model was used to simulate the response of the Potomac-Raritan-Magothy aquifer system to pumping stresses during the 18-year period, 1956-73. The model was used to compute projected potentiometric heads and trends to the year 2000. Three sets of conditions were simulated: (1) no increase in ground-water extractions, (2) continued growth in ground-water extractions at the rate of 3 percent annually, and (3) continued growth in ground-water extractions at the rate of 3 percent annually, in conjunction with the activation of a freshwater head barrier in the fresh-salty water transition zone.
From abstract: The U.S. Geological Survey maintains a saltwater monitoring network in New Jersey to document and evaluate the movement of saline water into freshwater aquifers that serve as sources of water supply. This report delineates areas in the Coastal Plain where existing or potential saltwater intrusion exists.
From purpose and scope: The purpose of this report is to document and evaluate water levels and changes in water levels in the major artesian aquifers of the New Jersey Coastal Plain. Fundamental data for ground-water investigations and management are provided.
Tabulated data presenting the results of field measurements and elemental analyses for ground water, stream water, and stream sediment samples taken from data collection sites in the state of New Jersey. Neutron activation analyses are given for U, Br, Cl, F, Mn, Na, Al, V, and Dy in ground water and stream water, and for U, Th, Hf, Ce, Fe, Mn, Na, Sc, -Ti, V, Al, Dy, Eu, La, Sm, Yb, and Lu in sediments (see pages 29-41 of report).
From abstract: "A thunderstorm during the evening of August 31 and the morning of September 1, 1978, caused flooding in a small area of South-central New Jersey. Maximum peaks of record occurred on the Upper Crosswicks Creek basin in the vicinity of Fort Dix, Wrightstown, and New Egypt. At New Egypt, high water crest elevations for Crosswicks Creek were approximately four feet higher than the previous maximum recorded on August 28, 1971.

Purpose and scope: The purpose of this study is to assess the impact of the development of Winslow Crossing on water resources., including the quantity and quality of streamflow, the quality of ground water, and water levels of the aquifer. Streamflow and water-quality data were collected for 7 years at four sites on the tributaries and the main stem of the Great Egg Harbor River. Water-quality data were also collected at an additional four surface-water sites. Water levels were recorded at four observation wells. These wells were sampled periodically for water-quality analysis. Samples were also taken from the main production well for Winslow Crossing.
Water-quality data collected in the upper Oyster Creek drainage basin indicate that the stream has excellent water quality except for a persistently low pH. The mean concentrations of the major inorganic ions were all less than 6.0 mg/L. Mean concentrations of total nitrogen and total phosphorus were 0.15 mg/L and 0.01 mg/L, respectively. Dissolved oxygen averaged 8.7 mg/L and 81 percent saturation. Low pH levels are typical of streams draining cedar swamps. In Oyster Creek, the pH tended to decrease downstream due to chemical and biological processes. The pH levels in swamps were one-half unit or more lower than the pH levels in the adjacent stream. Sharp declines in stream pH were noted during runoff periods as the result of the mixing of poorly-buffered stream water with more highly acidic water from surrounding swamp areas. The quality of ground water within the study area was similar to the quality of stream flow, except for higher iron and ammonia-nitrogen concentrations and a higher pH range of 4.9-6.5. Precipitation represented a major source of many chemical constituents in the ground- and surface-waters of Oyster Creek basin.
