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 ...
A drinking water standard of 0.05 mg/L (equal to 50 parts per billion, or ppb) arsenic was originally established in the United States by the Public Health Service in 1942. After the passage of the Safe Drinking Water Act of 1974 (SDWA), the Environmental Protection Agency (EPA) was given the power to set the maximum contaminant levels (MCLs ...
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 ...
National standards for drinking water quality, as well as standards concerning sanitation and sewerage collection, are set by the Department of Health. [66] The Philippine Department of Environment and Natural Resources (DENR) is the lead ministry for implementing water sector legislation, [ 67 ] whereas the Department of Finance takes the lead ...
In 2008 the Vermont legislature revised statute "Title 10, Chapter 048: Groundwater Protection" saying "the groundwater resources of the State are held in trust for the public" and "the groundwater resources of the State shall be managed to minimize the risks of groundwater quality deterioration by regulating human activities that present risks ...
The standards specify either Maximum Contaminant Levels (MCLs) or Treatment Techniques (enforceable procedures). [7] The most recent major standard-setting rules include: Ground Water Rule (2006) [8] Long Term 2 Enhanced Surface Water Treatment Rule (2006) for control of Cryptosporidium and other pathogens. [9]
The US Environmental Protection Agency (EPA) has published water quality criteria for turbidity. [14] These criteria are scientific assessments of the effects of turbidity, which are used by states to develop water quality standards for water bodies. (States may also publish their own criteria.)
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).
