Links to New Jersey ground-water data including hydrogeology with a geologic map and description of major aquifers, water levels including real-time data and drought levels, and water-quality information.
Links to reports for Pennsylvania on borehole geophysical studies, aquifer tests and properties, modeling, and hydrologic effects of an earthquake with links to MOC3D solute transport software package, program mission, and bibliography.
Explains why phosphorus is important, how it moves through the terrestrial water system, how we measure it, and what this means for people who need to manage or monitor human activities that produce it.
Study of the susceptibility and vulnerability of basin-fill aquifers in the region to ground-water contamination by synthesizing the information on ground-water quality conditions in 15 basins from previous studies.
In 1931, the USGS established a statewide network of wells in Pennsylvania to monitor water-level fluctuations. This network consists of 68 wells to monitor ground water conditions during droughts. Links to ground-water data, hydrographs, and levels.
