C8 found in wastewater, air at DuPont's Circleville plant

Associated Press

CIRCLEVILLE, Ohio - State officials have found a chemical used to make Teflon in wastewater from DuPont's Circleville plant that trickles into the Scioto River, according to documents obtained by a newspaper.

Tests from one holding pond at the plant that drains into the river showed levels of C8 at 8.1 to 9.8 parts per billion, according to Ohio EPA records obtained by The Columbus Dispatch.

Another holding pond that doesn't run into the river had levels of the chemical, also known as ammonium perfluorooctanoate, ranging from 9.4 to 13.2 parts per billion.

One part per billion is the equivalent of 50 drops of water in an Olympic-sized pool. DuPont conducted the wastewater tests in July and October 2004.

C8 also was found in the air around those plants, but it was not clear how much because those records were not released.

The health effects of drinking water contaminated with the chemical have not been determined, but a panel of scientists from the U.S. Environmental Protection Agency said in June the chemical should be considered a likely cancer risk.

DuPont is paying for health tests of up to 80,000 Ohio and West Virginia residents where the chemical was discovered in drinking water as part of a settlement of a class-action lawsuit. The company says it uses less of the chemical at the Circleville plant than at the other facilities.

The company also has tested for C8 in wells used for drinking water in surrounding Pickaway County and nearby Ross County. The Pickaway tests didn't uncover C8 contamination, and Ross County is still awaiting results of tests done there six weeks ago, officials said.

Rob Banerjee, manager of the Circleville plant, said on Wednesday that the company started collecting wastewater and incinerating it in December to prevent the chemical from getting into the drinking water.

He said the chemical was not detectable in samples collected about two months ago upstream and downstream from plant.
