ADEQ is holding this virtual meeting to discuss the Aquifer Water Quality Standards (AWQS) setting process. ADEQ is required by state law to propose AWQS when a new drinking water maximum contaminant level (MCL) is determined by the federal Environmental Protection Agency. 

This meeting will present our draft approach for either adopting drinking water MCLs as AWQS or developing alternative AWQS. We are planning to open a rulemaking docket to this end, pursuant to state law. The following seven MCLs are planned to be the scope of the future rulemaking docket(s):

• arsenic
• bromate
• chlorite
• microbiological contaminants
• haloacetic acids
• total trihalomethanes
• uranium
