The Little Hocking Water Association (LHWA) today urged DuPont to immediately move forward with construction and operation of DuPont’s proposed carbon treatment facility to remove C8 from the LHWA water supply.

According to LHWA general manager Bob Griffin, “The U.S. EPA’s November 20, 2006 Consent Order setting an interim, emergency drinking water standard for C8, coupled with the Ohio EPA’s October 26, 2006 approval of the revised construction plans for the carbon treatment facility, should remove whatever final roadblock was preventing DuPont from constructing the proposed treatment system.” 

DuPont claims that the interim treatment plant project will reduce C8 contamination from the LHWA water supply to undetectable levels, although it is yet to be determined how well the carbon filtration system will work at the high levels of C8 discovered in the LHWA wellfield.   The November Consent Order requires DuPont to operate and maintain the carbon treatment system for LHWA until DuPont demonstrates to the satisfaction of the U.S. EPA that the source water in the system, prior to treatment by LHWA, contains less than 0.50 parts per billion of C8 for four consecutive quarters, or until the U.S. EPA determines that a different standard should apply to drinking water. DuPont agreed to the U.S. EPA order.

Griffin said that LHWA is ready and eager for DuPont to move forward on the construction of the carbon treatment plant so that it can begin operating as soon as possible in accordance with the U.S. EPA Consent Order and Ohio EPA-approved plans.

“It has been almost five years since we discovered that C8 was contaminating our water supply and exposing our customers to this chemical, which the U.S. EPA has determined may present ‘an imminent and substantial endangerment to human health’ at concentrations well below what is present in our water.  Construction of this facility is long overdue and should start immediately.   This interim treatment system needs to start operating as soon as possible so that we can evaluate how effectively it is going to perform in removing C8 from our water supply.”
