Arsenic is both naturally occurring and artificially produced, and the toxin is very dangerous since it often has no color, taste, or smell. This graphic breaks down how arsenic gets into drinking water supplies and how arsenic affects the U.S. on the state level.
California, Texas, Michigan, and Arizona top the list of U.S. states with public water systems in violation of the federal standard for arsenic. Joining these states are Arizona, New Mexico, Idaho, Nevada, and Illinois at the top of the list of states with more than 30,000 people potentially affected by high arsenic levels.
