In the last case, EPA is permitted to choose an MCL that balances the cost of treatment with the public health benefits. MCLs require monitoring, remediation, and public notice when standards are exceeded. As of 2019 EPA has issued 88 standards (78 MCLs and 10 Treatment Techniques) for microorganisms, chemicals and radionuclides.
88:(MCLG). MCLGs are non-enforceable public health goals. The legally enforced MCL is then set as close as possible to the MCLG. The MCL for a contaminant may be higher than the MCLG because of difficulties in measuring small quantities of a contaminant, a lack of available
