The Safe Drinking Water Act requires the US EPA to set standards for drinking water quality in public water systems (entities that provide water for human consumption to at least 25 people for at least 60 days a year). [3] Enforcement of the standards is mostly carried out by state health agencies. [4]
Maximum contaminant levels (MCLs) are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality. [ 1 ] [ 2 ] An MCL is the legal threshold limit on the amount of a substance that is allowed in public water systems under the Safe Drinking Water Act (SDWA).
Another study, a population study this time by Kessing et al., [51] showed a negative correlation between Alzheimer's disease deaths and the presence of lithium in drinking water. [48] Areas with increased lithium in their drinking water showed less dementia overall in their population. [48]
Water designated for human consumption as drinking water may be subject to specific drinking water quality standards. In the United States, for example, such standards have been developed by EPA under the Safe Drinking Water Act, [14] are mandatory for public water systems, [15] and are enforced via a comprehensive monitoring and correction ...
