This is near our old supernate disposal ponds. We removed these ponds in 1980's, but ground water contamination continues. We have some water wells for process use with 60 PPB levels of C-8, and site drinking water well has 0.5-1.1 PPB C-8 in it. So we have very big problem here at Parkersburg. The above numbers are estimates, because final numbers are being sent to me. I will send them to you when I get them. There is some confusion due to lab error and new laboratory.
