The nonprofit agency operating Tucson International Airport will soon start work on a detailed investigation of the extent of groundwater contamination by potentially cancer-causing PFAS compounds that were historically used on its property. The investigation is due to a new agreement the Tucson Airport Authority signed with the U.S. Environmental Protection Agency. Its purpose will be “to determine the nature and extent of contamination and any threat to the public health, welfare, or the environment caused by any release or threatened release of PFAS hazardous substances, pollutants, or contaminants” from airport property, the agreement says. The agreement also commits the authority to conduct a feasibility study after the investigation to determine the best cleanup options if warranted. The agreement will be carried out under the federal Superfund program in which toxic waste sites are cleaned up under EPA’s oversight.
