Water Quality Authority

Pima County Department of Environmental Quality ensures that facilities within Pima County comply with the many regulations pertaining to environmental multimedia. PDEQ gets this permitting and inspection authority from federal and state legislation and county ordinances. PDEQ also has entered into a delegation agreement with the Arizona Department of Environmental Quality (ADEQ).

PDEQ has permitting and inspection authority for those activities which have the potential to impact water quality (see table 1). Complaints related to these sources are also investigated. ADEQ has specifically reserved jurisdiction over the regulatory items also listed in Table 2.
