Focazio Arsenic in Ground-Water Resources of the United States. (... a concise 4-page Fact Sheet about the occurrence and concentrations of arsenic in ground water in the United States. The data behind this overview was collected by the United States Geological Survey [USGS]; as the document states--the USGS has collected and analyzed arsenic in potable [drinkable] water from 18,850 wells in 595 counties across the United States during the past two decades. The publication of this Fact Sheet was spurred by the recommendation of the National Research Council [of the United States] in 1999 to lower the current maximum contaminant level [MCL] allowed for arsenic in drinking water of 50 µg/L [micrograms per liter], citing risks for developing bladder and other cancers. Other keywords and phrases -- cancer, groundwater, human health, naturally occurring, public and private water supply, skin, standards, toxic -- from the text of the Fact Sheet; please see the bibliography) United States Department of the Interior, United States Geological Survey USGS Fact Sheet 063-00 (May 2000): 4 pages (in PDF). **The complete text of the Fact Sheet is currently available through the Web site of the United States Geological Survey (the report is available in portable document format [PDF--which requires the Adobe Acrobat Reader in order to be viewed] and in HTML).** Subcommittee on Arsenic in Drinking Water, National Research Council [of the United States] Arsenic in Drinking Water. (... in 1996, EPA's [the United States Environmental Protection Agency] Office of Water requested that the National Research Council [NRC] independently review the arsenic toxicity data base and evaluate the scientific validity of EPA's 1988 risk assessment for arsenic in drinking water in the United States. That charge lead to this detailed report one of whose recommendations was that on the basis of its review of epidemiological findings, experimental data on the mode of action of arsenic, and available information on the variations in human susceptibility, it is the subcommittee's consensus that the current EPA MCL [maximum contaminant level] for arsenic in drinking water of 50 µg/L [micrograms per liter] does not achieve EPA's goal for public-health protection and, therefore, requires downward revision as promptly as possible. Subsequently, during the last year of the administration of President Bill Clinton, the EPA did make recommendations for a new lower maximum contaminant level [MCL] for arsenic in drinking water. Other keywords and phrases -- cancer, concentration, contaminants, ground water, groundwater, human health, inorganic, naturally occurring, organic, public drinking water supplies, skin, standards, surface water, toxic -- from the Executive Summary of the report) National Academy Press (1999): 330 pages. **The complete text of this book is currently available through the Web site of National Academy Press -- look for the Open Book icon** How to find the above journals, magazines, and other publications?
