Safe Levels of Uranium in Drinking Water

The US EPA sets the standards for public drinking water.These standards are known as the Safe Drinking Water Limits.The limits for many chemicals and contaminants are health-based limits calculated by assuming that a person drinks 2 liters of water a day for 70 years.The safe limits are known as Maximum Contamination Limits or MCL’s.EPA considers water above the MCL as being unsafe.The MCL for uranium in public drinking water is 30 micrograms per liter (30 ug/L).It is important to note that the MCL for uranium was established because of its toxicity as a heavy metal, not as a result of its radioactivity.
