ADEQ: Standards

Surface water quality standards are one of the cornerstones of the Clean Water Act. These standards define the water quality goals for Arizona streams and lakes. The standards also provide the basis for a water quality-based approach to controlling discharges of pollutants to surface waters.

Triennial Review of Surface Water Quality Standards
ADEQ's proposed revisions to the surface water quality standards were published in the Arizona Administrative Register on April 4, 2008. The Notice of Proposed Rulemaking is available for downloading from the Office of the Secretary of State .

ADEQ has scheduled two public meetings to receive public comments on the proposed rules:
