DuPont faces more legal woes Tuesday after a lawsuit concerning a chemical used in the production of Teflon surfaces.

The civil suit surrounding C-8 comes from the Little Hocking Water Association, which serving 12,000 Washington and Athens County residents.

The timing comes on the exact date an agreement expired that had extended the time required to file a lawsuit.

When DuPont didn't extend the agreement, attorneys for the water association say they had no choice but to file.

The association is one of four in Ohio affected by the C-8 chemical used at the DuPont company.

The group has battled the chemical for four years, but Monday, the association filed a civil suit against the Teflon producer.

The association’s attorney David Altman says, "A water association doesn't operate on proving that someone’s injured. We operate on the principles of public health."

The lawsuit states DuPont has polluted Little Hocking's 45 acres of well fields.

It further states the association has spent hundreds of staff and professional hours planning for a new filtration plant, which DuPont promised to build.

Altman says, "More important than the money is the issue of getting DuPont to do the right thing by court order if they won't do it by agreeing...and that is to clean up the well field, provide alternate water."

Three other water associations on the Ohio side of the river have water filtration systems in place. The attorney for the Little Hocking Association says the circumstances there are actually much worse than the other water groups.

He says he hopes the lawsuit will speed up the process for a filtration system or alternate plan to go in place.

Altman says the lawsuit probably wouldn’t have been filed if the agreement had been extended. However, he adds he and his client have worked with DuPont in the past and will continue to do so to clear the water

DuPont did respond to the lawsuit Tuesday afternoon.

"We fail to see how the best interests of LHWA's customers are served by a lawsuit and more delays rather than having filtered water and a peace of mind."

It also says, it has been working for two and a half years on a filtration system that was to be installed at the sole cost of DuPont.
