Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...

The National Water Quality Inventory Report to Congress is a general report on water quality, providing overall information about the number of miles of streams and rivers and their aggregate condition. [65] The CWA requires states to adopt standards for each of the possible designated uses that they assign to their waters.

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]
Water quality laws govern the protection of water resources for human health and the environment. Water quality laws are legal standards or requirements governing water quality, that is, the concentrations of water pollutants in some regulated volume of water. Such standards are generally expressed as levels of a specific water pollutants ...
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).
WQBELs are based on ambient water quality standards. [22] Permit components NPDES permit components. All NPDES permits must contain the following five components: Cover page – indicates authorization for discharging and its locations; Effluent limits – limits used to control discharges through technology-based or water quality-based standards
