What Is Chromium-6 in Water?

Chromium-6, also called hexavalent chromium, is a form of chromium that can enter water through industrial pollution, manufacturing waste, or natural deposits in the ground. It has received attention because high levels may pose health concerns.

Chromium-6 cannot usually be seen, smelled, or tasted, so water testing is the best way to know if it is present. Treatment options may include reverse osmosis systems or other specialized filtration equipment designed to reduce chromium in drinking water.
