Changes in Water Levels and Storage in the High Plains Aquifer, Predevelopment to 2007 [ More info] Summarizes changes in water levels and drainable water in storage in the High Plains aquifer from predevelopment (before about 1950) to 2007.
Changes in water levels and storage in the High Plains Aquifer, predevelopment to 2009 [ More info] Summarizes graphically the areas where water levels have dropped, and by how much, in this extensive underground water reservoir that covers several states in the mid-continent.
Edwards Aquifer online resources [ More info] Recharge and discharge summaries and other data, aeromagnetic survey map, and publications on Edwards Aquifer, Texas.
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.
High Plains aquifer resources and information [ More info] Links to reports, bibliographies, and other information on the High Plains aquifer.
Land subsidence and aquifer-system compaction in the Tucson Active Management Area, south-central Arizona, 1987-2005 [ More info] Results of ground-surface monitoring and borehole water table measurements document subsidence of the land surface correlative with changes in the ground water.
Major aquifers in New Jersey [ More info] Geologic description of the principal coastal and non-coastal aquifers in New Jersey and relationship to water quality and water supply.
Nutrients National Synthesis Project: nutrients in rivers, streams, and aquifers in the United States [ More info] This Nutrients National Synthesis Project site on the U.S. study of nutrients, especially nitrogen and phosphorus, as contaminants in high concentrations links to an overview, study team, featured reports, publications, and national datasets.
Principal aquifers can contribute radium to sources of drinking water under certain geochemical conditions [ More info] Knowledge of the geochemical processes controlling radium occurrence in groundwater may help water-resource managers anticipate and minimize human exposure to this cancer-causing element.
Redox Conditions in Selected Principal Aquifers of the United States [ More info] Summarizes measurements of ground-water chemistry that affect the vulnerability of aquifers to contamination. Data are from aquifers throughout the conterminous US and Alaska.
