The chemical, physical, and biological characteristics of water, usually in respect to its suitability for a particular purpose.
Geochemistry of the Arbuckle-Simpson Aquifer [ More info] Describes the geographic extent, quality, origin, and dynamic character of this aquifer located in south central Oklahoma.
Geologic framework and process of the Lake Pontchartrain Basin [ More info] Field methods, topics of investigation, shoreline changes, publications, and satellite imagery related to geologic and hydrologic processes affecting Lake Pontchartrain and adjacent lakes which form a large estuary in the Gulf Coast region.
Georgia's Stream-Water-Quality Monitoring Network, 2006 [ More info] USGS stream-water-quality monitoring network for Georgia represents an aggregation of smaller networks and individual monitoring stations, with map and link to data.
Great Lakes issues [ More info] Water resources problems of the Great Lakes including water use, bacterial contamination on beaches, status of water resources, and ground water flow.
Ground-water data for the Nation [ More info] 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.
Ground-water flow and other computer simulations for Utah [ More info] Identifies computer models in USGS publications developed to study ground water for many areas of Utah.
Ground-water monitoring for pesticides in Wyoming [ More info] Sampling program to determine if pesticides are present in ground water, in accordance with Wyoming's Generic State Management Plan for Pesticides in Ground Water (SMP).
Groundwater Quality in the Central Eastside San Joaquin Valley, California [ More info] Summary of a detailed study in this agricultural area.
Groundwater Quality in the Kern County Subbasin, California [ More info] Arsenic was the trace element most frequently present at high concentrations here. High concentrations of arsenic result from the interaction of groundwater with naturally occurring minerals.
Groundwater Quality in the Southeast San Joaquin Valley, California [ More info] Arsenic and nitrate are the constituents found most commonly at high concentrations in the primary aquifers. Arsenic comes from natural sources and is affected by pH and dissolved oxygen.
