Facility would remove chemical left from south-side TCE cleanup
City facing major new expense to treat water

Changing federal standards for a chemical left behind after the cleanup of TCE and TCA from south-side groundwater could force the city - and water customers - to spend millions of dollars on a new treatment plant.

Removing trichloroethylene, or TCE, and trichloroethane, or TCA, from groundwater leaves behind a chemical called 1,4 dioxane, which was used to prevent the breakdown of TCA.

Although the massive federal Superfund site on the south side is able to strip out the TCE and TCA, the 1,4 dioxane does not evaporate and stays in the water.
