Arsenic and Drinking Water
The Arsenic and Drinking Water fact sheet provides key information about what arsenic is, where it comes from, and why it may be found in private wells. It outlines the health risks of long-term exposure to arsenic, including increased risk of certain cancers and other health problems, and emphasizes that arsenic has no taste, color, or smell so regular testing is the only reliable way to detect it. The fact sheet explains the drinking water standards for arsenic and offers guidance for well users on when and how to test for arsenic, how to interpret test results, and what actions to take if levels exceed health-based guidelines. It outlines specific everyday uses, like drinking, cooking, and bathing and clearly states whether these actions are safe based on the level of arsenic in the water. It also introduces effective treatment technologies for reducing or removing arsenic for public drinking water systems and private wells with a reminder that boiling water does not remove arsenic.
