Under the Safe Drinking Water Act (SDWA), EPA has set maximum contaminant levels (MCLs) to establish limits for certain substances in drinking water, including microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals, and radionuclides. The MCLs for radionuclides were calculated based on long-term, chronic exposures over the course of a lifetime 70 years. RadNet drinking water data should not be substituted for SDWA data because the analytical methodologies are not the same.
What federal standards exist that address radiation in drinking water?
