New plant to remove carcinogen from water 1,4-dioxane remains on south side despite city's cleanup of TCE, TCA Tony Davis Arizona Daily Star July 7, 2011Tucson hopes to start construction next year on a $10 million plant to clean up another cancer-causing chemical from south-side groundwater, more than 15 years after authorities began cleanup of TCE and TCA from that aquifer.
This time authorities are targeting 1,4-dioxane, which has not been removed from the groundwater as the other solvents were being cleaned up.
Treated water containing low amounts of that carcinogen has been delivered for years to homes and businesses in a wide area of Tucson (see map, Page A4). Federal officials say the health risk from drinking that water is "exceedingly low," but the compound is significantly more toxic than previously believed.
City officials hope to get reimbursed for money needed to build and to operate the plant - pegged at another $250,000 annually - by the Air Force. It was Air Force contractors who dumped the polluting solvents into the groundwater starting more than a half-century ago.
