Source: EPA National Primary Drinking Water Regulations

Where It Comes From

Natural deposits in rock and soil are the primary source. Also from erosion of natural deposits, runoff from orchards, and runoff from glass and electronics production waste.

Where It's Commonly Found

Groundwater in the western U.S., parts of New England, and the upper Midwest. Private wells in areas with naturally high arsenic geology are particularly at risk.

Approximately 2,200 community water systems have reported arsenic levels above EPA's MCL. An estimated 43 million Americans rely on domestic wells, many in areas with naturally elevated arsenic.
