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 ...

In aqueous solutions (solutions of water), water gradually (over the course of hours) hydrolyzes polyphosphates into smaller phosphates and finally into ortho-phosphate, given enough water. Higher temperature or acidic conditions can speed up the hydrolysis reactions considerably.
The International Organization for Standardization (ISO) published [when?] regulation of water quality in the section of ICS 13.060, [57] ranging from water sampling, drinking water, industrial class water, sewage, and examination of water for chemical, physical or biological properties. ICS 91.140.60 covers the standards of water supply ...

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 ...
Enforcement of drinking water standards in small water systems is less consistent than enforcement in large systems. As of 2016 more than 3/4ths of small community water systems that were classified as having serious health violations by EPA still had the same violations three years later.
