Arsenic in ground water of the United States
Entry ID: USGS_ARSENIC_H2O


Summary
Abstract: [From Arsenic in ground water of the United States, "http://water.usgs.gov/nawqa/trace/arsenic/"

Arsenic is a naturally occurring element in the environment. Arsenic in ground water is largely the result of minerals dissolving naturally from weathered rocks and soils. Several types of cancer have been linked to arsenic in water. The US Environmental Protection Agency is currently reviewing the maximum contaminant level of arsenic permitted in drinking water, and will likely lower it, as recommended last year by the National Research Council.

The USGS has developed a map that shows where and to what extent arsenic occurs in ground water across the country. Highest concentrations were found throughout the West and in parts of the Midwest and Northeast.
