enforceable drinking water standards that are protective of public health to the extent feasible with current technology.
(MCLs). Under the authority of the Safe Drinking Water Act, the U.S. EPA sets MCLs for groundwater. The National Primary Drinking Water Regulations (40 CFR 141) specify MCLs for radionuclide contaminants in drinking water. For all radionuclides, the combined dose to an individual from water consumption should not exceed 4 mrem/yr to the whole body or any internal organ.
The maximum permissible level of a contaminant in water that is delivered to a user of a public water system.
Maximum Contaminant Levels (MCLs) - Legally enforeable drinking water standards required by the Safe Drinking Water Act.
MCLs are legal drinking water quality standards defined by the Safe Drinking Water Act. MCLs represent contaminant concentrations in drinking water that someone could be exposed to on a daily basis over a life time without adverse health effects.
Legally enforceable drinking water standards required by the Safe Drinking Water Act. Standards set by the Environmental Protection Agency establish the maximum permissible concentration of selected contaminants in public water supplies. Contaminants are included on the list if they pose a public health risk. For example, 10 ppm is the MCL for nitrate-nitrogen (NO³-N).

The maximum allowable level of a contaminant that federal or state regulations allow in a public water system. If the MCL is exceeded, the water system must treat the water so that it meets the MCL.
MCLs represent contaminant concentrations in drinking water that EPA deems protective of public health (considering the availability and economics of water treatment technology) over a lifetime (70 years) at an exposure rate of 2 liters of water per day.
