Uranium Testing Results in Public Water

Uranium is a naturally and commonly occurring radioactive element. Because uranium is found everywhere in small amounts, people always take it into the body from the air, water, food, and soil. In most areas of the United States, low levels of uranium are found in the drinking water. Higher levels may be found in areas with elevated levels of naturally occurring uranium in rocks and soil. The maximum contaminant level (MCL) for uranium in drinking water is 30 mcg/L.
