This week marked a major milestone: the completion of the TARP expansion and new PFAS treatment facilities at the Tucson Airport Remediation Project, better known as TARP.
This $25 million investment was supported through federal, state, and local collaboration and adds a new layer of protection for Tucson’s groundwater, helping address PFAS contamination and protect and restore this critical local resource.
This progress reflects years of partnership to keep Tucson's water safe and secure.
Thank you to Governor Katie Hobbs, Mayor Regina Romero, Arizona Department of Environmental Quality, U.S. EPA Pacific Southwest Region, our federal and state delegations, and especially the members of the Unified Community Advisory Board (UCAB), whose decades of advocacy and partnership have whose sustained leadership and partnership have helped guide this essential work.
