DEEPWATER, N.J. (AP) — DuPont says it has found chemical residues from a Teflon ingredient in groundwater near its Chambers Works plant.

The traces of the chemical PFOA were found in nine wells around the plant in Deepwater, N.J. The concentrations ranged as high as 35 times the alert level established last year by New Jersey regulators.

Plant manager Bland Dickey said in a statement Tuesday that the company was committed to minimizing PFOA releases and was making good progress toward eliminating use of the material. DuPont has committed to eliminate use of PFOA by no later than 2015.

DuPont has stated that there is no evidence of health threats from PFOA, but a federal advisory panel recommended classifying it as a probable carcinogen.
