ADEQ's Southern Regional Office (SRO) in Tucson serves Cochise, Graham, Greenlee, Pima, Santa Cruz and Yuma counties.
Responsible for a portion of agency programs, the SRO coordinates ADEQ's activities to protect public health and the environment along the Arizona-Mexico border, conducts inspections and complaint investigations of permitted and non-permitted air pollution sources, water and wastewater facilities, responds to emergencies that threaten public health and the environment and processes open burn permit applications.
Some Water Quality Assurance Revolving Fund (WQARF) sites in southern Arizona are governed and funded by the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), also known as Superfund. Sites that pose the greatest potential threat to human health and the environment are put on the National Priorities List (NPL). There are eight NPL Superfund sites in the Tucson area. In addition to the NPL and the WQARF Registry sites, the Superfund Programs Section also provides state review and oversight at one Department of Defense (DoD) site.
The SRO also monitors and tests public drinking water systems to ensure safe, potable water supplies, inspects the construction and operation of wastewater treatment facilities and on-site systems, oversees the investigation and cleanup of contaminated soil and groundwater Superfund sites and supports ADEQ's groundwater monitoring, sourcewater assessments and water quality permitting activities.
Two Community Liaisons support SRO. The Southeast Arizona Community Liaison offers assistance to Cochise, Graham, Greenlee and Santa Cruz counties, and the Southwest Arizona Community Liaison offers assistance to La Paz and Yuma counties. They conduct broad outreach within the regions they serve and may assist/educate the regulated community and general public on ADEQ requirements and services.

U.S. EPA EMPACT Project Partner
ADEQ is partnering with the Tucson Water Department, the the University of Arizona and several Pima County agencies, businesses and organizations to provide citizens near real-time information about the quality of their drinking water. This effort is made possible by an Environmental Monitoring for Public Access and Community Tracking (EMPACT) grant from the U.S. Environmental Protection Agency.
ADEQ regulates Arizona public drinking water systems, such as Tucson Water, under the federal Safe Drinking Water Act. The Act requires the U.S. EPA to set drinking water quality standards and monitoring requirements to protect public health. Public water systems are responsible for complying with all state and federal requirements, including sampling, reporting and paying for all water quality analyses. ADEQ's Water Quality Compliance Section implements the requirements of the Safe Drinking Water Act by reviewing water quality monitoring data, inspecting public water systems and initiating enforcement actions when necessary.
ADEQ's role as a partner in the EMPACT project is to verify Tucson Water's compliance with federal and state drinking water regulations as stated in the Safe Drinking Water Act and the Arizona Administrative Code.
