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.
A valve failed in a research well, causing an uncontrolled eruption of steam and hot water. Video program shows technical problems encountered in controlling and capping the well.
Map of New Jersey showing the locations of all well sites where ground water-quality data exists in the USGS National Water Information System (NWIS) database.
National Water Information System (NWIS) real-time data on selected ground water sites, ground water level data, site inventory of wells, test holes, drains, springs and excavations and ground water-quality data for the United States.
Links to maps of New Jersey showing nitrate levels, pesticides, Total Volatile Organic Compounds (VOCs), and radium in wells and land use of the 1970s.
Project summary, photos of logging truck, and bibliographies on log interpretation techniques and instrumentation to record geophysical data in wells and test holes for studying ground water hydraulics and evaluate waste disposal sites.
Site to locate most recent or archive reports for end-of-the-month hydrologic conditions with descriptions, data, charts, and maps giving an overview of water conditions during the month for the state of New York.
Describes and provides examples of impacts of human-induced land subsidence resulting from the extraction of subsurface water, including aquifer-system compaction, drainage of organic soils, dissolution and collapse of susceptible rocks.
Describes cooperation of the USGS office in Las Vegas, Nevada, with the Department of Energy to address environmental and scientific issues at the Nevada Test Site and vicinity with links to project information.
Description of the studies of the ground water system in the Yakima River Basin and how it interacts with rivers and streams in the basin. Includes links to project status, datasets, maps, project summaries, news releases and bibliographies.
