Advanced Treatment for 1,4-Dioxane in Tucson, Arizona
TrojanUV Solutions

The Tucson Water Advanced Oxidation Site in Pima County, Arizona, has been contaminated with volatile organic compounds (VOCs) since 1942. In 1981, unsafe levels of trichloroethylene (TCE) were found in municipal water wells, leading to the shutdown of eleven wells. The Tucson Airport Remediation Project (TARP) was established, and a groundwater treatment system was commissioned in 1994. However, 1,4-dioxane, a contaminant not easily removed by the existing system, was later detected. To address this, a UV Advanced Oxidation Process (UV AOP) was installed to effectively remove 1,4-dioxane.
