Drinking Water Fact Sheet: Arsenic

Arsenic is a poisonous heavy metal, and exposure to it can occur through inhalation, dermal contact and ingestion. Most exposure, however, occurs through consumption of arsenic-contaminated food and water. Contamination of drinking water supplies with arsenic can occur by runoff of arsenical pesticides, dissolution of natural mineral deposits, atmospheric deposition, industrial releases, or improperly disposed chemicals.
