From 1980 to the fall of 1993, Tomco Wood-Preserving used the property to pressure-treat wood products intended for exterior construction. In 1999 the presence of arsenic and chromium impacts in surface and subsurface soils were identified. In 2000, on-site buildings were demolished and a fence was erected around the facility. The Voluntary Remediation Program (VRP) accepted the Tomco application in May 2001. The remediation consisted of excavation along with in-situ EnviroBlend® remediation. A total of 2,872 tons of arsenic-and-chromium-containing soil and 116 tons of debris were excavated as part of the source removal operation. After groundwater was sampled for four (4) consecutive quarters, it was determined that arsenic did not exceed acceptable risk levels, and subsequently, VRP issued formal closure to the site.
These case studies are examples of the extensive work EnviroBlend has completed across the United States. For more information on our project experience please contact us.
