TerraTherm Selected for ISTD Design and Implementation in Denmark

January 2006

TerraTherm and NIRAS were selected as specialty contractors for what is believed to be the worst chemical disposal site in Denmark, Cheminova Hoefde 42, a complex pesticide landfill in sand dunes at the shore of the North Sea. During the 1950s and 60s, thousands of drums containing wastes from the production of pesticides such as parathion, malathion, MCPP, and DDT were placed in a shallow, unlined disposal pits. For decades, contamination seeping from the pit known as "Hoefde 42" contaminated the shoreline and led to a total ban on fishing for seafood within tens of miles of the site - the locals regularly encountered hundreds of fish belly-up in the shallow fjords, and numerous fishermen and locals fell ill with contaminant-induced diseases. Now, the Danish EPA and Ringkoebing Amt (the local authority) have taken control of the disposal site and will be testing the most promising in-situ remediation methods. NIRAS and TerraTherm were awarded the contract for evaluating the thermal remediation options, including hot water circulation, steam injection, electrical resistance heating, and thermal conduction heating. Laboratory studies will be conducted in 2006. Pilot testing of the most promising methods is planned for 2007, followed by full-scale remediation.
