In addition to laws, criteria and systems discussed above, compliance with several standards play an important role in maintaining drinking water quality. These standards provide for development of criteria when none are available from the regulating body. For example, compliance with National Sanitation Foundation International/American National Standards Institute (NSF/ANSI) Standard 61, which addresses the potential for constituents to leach from components of drinking water systems into water moving toward the tap, is required under many state laws and regulations.
