Breccia-pipe uranium mining in northern Arizona; estimate of resources and assessment of historical effects [More info]: Estimates of uranium resources affected by land withdrawal, effects of previous breccia-pipe mining, water-chemistry data for streams and springs, and potential biological pathways of exposure to uranium and associated contaminants.
Groundwater quality in the Colorado River basins, California [More info]: Five trace elements with human-health concerns were detected at high concentrations: arsenic, boron, fluoride, molybdenum, and strontium. Chromium was detected at moderate concentrations.
Groundwater quality in the Indian Wells Valley, California [More info]: Five trace elements with human-health concerns were detected at high concentrations: arsenic, boron, molybdenum, strontium, and vanadium. Chromium and fluoride were detected at moderate concentrations.
Groundwater quality in the Madera and Chowchilla subbasins of the San Joaquin Valley, California [More info]: Uranium, arsenic, and nitrate were the inorganic constituents that were most frequently detected at high concentrations, mostly in shallower wells. High and moderate concentrations of arsenic were detected in deeper wells.
