Contamination fouling drinking water in parts of Marana and near Davis-Monthan Air Force Base in Tucson is due for separate cleanups soon.
The cleanups will dramatically lower concentrations of what health authorities say are excessive levels of a family of chemicals that have been known to be in the city’s and town’s groundwater supplies since 2016.
In Tucson, the Arizona Department of Environmental Quality will start constructing in the spring and start operating in the summer a pilot treatment plant to remove PFAS compounds from wells just north of Davis-Monthan. The wells lie in the city’s central wellfield, long Tucson Water’s most important groundwater source.
