The City of Vienna will officially go back on its own water today at 10 a.m.

Vienna Mayor Randy Rapp said the carbon filters put in place this summer by Chemours are working as expected, prompting the move to disconnect the City of Vienna from the City of Parkersburg’s water system.

”We received our lab results (Monday) morning at 9:15 a.m. showing the carbon filters are working perfectly,” he said ”We now have non-detectable levels of C8 in our water system.”

The city hooked into the Parkersburg Utility Board system over the summer after the U.S. Environmental Protection Agency established a health advisory for long-term exposure to C8, also called PFOA, of 0.07 parts per billion, lowered from the 0.4 ppb short-term health advisory set in 2009.

C8, an unregulated chemical by the EPA which was used to make Teflon at the former DuPont Washington Works, now Chemours, is a suspected carcinogen and has been linked, in a study, to six diseases in humans — kidney cancer, testicular cancer, ulcerative colitis, thyroid disease, pregnancy induced hypertension including preeclampsia and hypercholesterolemia — and was the subject of a class action lawsuit settled in 2005. A science panel established by the settlement of a lawsuit against the company studied the health data of 70,000 residents in the region.

Most of Vienna’s wells originally showed concentrations of C8 greater than 0.1 ppb.

The City of Parkersburg stepped in to help the City of Vienna in May. The connection with Parkersburg served about a third of Vienna water customers from 23rd Street south, which covered the bulk of commercial customers in the city.

Parkersburg Mayor Jimmy Colombo said they were glad to be able to help.

”We are proud the city was able to step up and help our neighbors,” he said.

The connections will be left in place in case something happens in the future where either city would need assistance like this again.
