The company has made several steps over the years, including a cleanup of the main site. The lead liable party was International Paper Company. However, the CDDs have increased, possibly from finding their way into the water table.Īccording to Roll, the liable persons were notified in 1997, and have been working to right the site. Roll also explained that there has been what appears to be a decrease in contamination levels over the last few years amongst the plume area, when measurements have been compared from 20. ![]() The plume of contamination has a general motion northeast, away from the site, traversing with the natural movement of the groundwater. The Pentachlorophenol is now in the water table and has formed what they call a “plume,” which DEQ, and other parties, have been tracking. The latter is not very water soluble, but attaches tightly to soil particles and was tracked up and down roadways across the site, where the tests showed contamination on the surface along old roadways. The first of these is water soluble and has been carried by water deep into the water table and across the surface of the site. Pentachlorophenol and Chlorinated Dibenzo-p-Dioxins (CDDs). Roll explained that there were two main forms of contamination on the site. Roll also mentioned, “We believe that just driving vehicles back and forth across the facility tracked contaminants through the area.” He cited studies and numerous tests that have been done on the area. There were also several spills on the site, and run-off carried it into adjacent ditches and streams. Roll explained that the contamination was caused by the outdoor wood treatment in the main yard that allowed time for the treatment chemicals to drip onto the ground below treated wood and to seep below the soil. ![]() He then segued back to give background on the site and contamination. He explained that they are in the feasibility study phase, looking into what projects could be feasible on the current site. He has been dealing with the site for nearly 14 years, and started his presentation talking about the current state of the project. To speak for DEQ on the contamination was Environmental Project Manager for the site, Bob Roll.
