BT Kemi Efterbehandling
In Calgary, Canada, Dr Bruce McGee had never heard of Sweden’s first environmental scandal caused by BT Kemi. Now his patented IT-DSP-system will help clean the contaminated soil in Teckomatorp – and soon this choice of technique will make the village more known for high temperature in situ remediation than the 1970’s scandal.
“That is really beautiful, isn’t it!?” Dr Bruce McGee, President and CEO of Canadian McMillan-McGee Corporation, admires the 235 heater wells, 26 extraction wells, six temperature wells and eleven vent wells that have been installed as part of the in situ thermal treatmentsystem.
Come spring the contaminated soil is to be heated to 300 degrees Celsius and phenoxy alkanoic acids, chlorophenols and chlorocresoles will vaporize to be collected in a treatment system above ground level. This isn’t the first time Dr McGee’s Inductive Thermal Dynamic Stripping Process (IT-DSP) is used for in situ remediation – but the high temperatures needed is almost unique.
“I only know of four or five other high temp-projects in the world. This is really something special and the world is already talking about the BT Kemi remediation in Teckomatorp” says Dr McGee.
For a couple of days in early December Dr Bruce McGee visited Teckomatorp to test three of the heaters and to collect data for the upcoming remediation.
McMillan-McGee is the partner of contractor Geoserve, and the patented IT-DSP in situ technique is Dr McGee’s invention. This technique is what makes the high temperature remediation possible.
“Contaminated soil can be found all over the world and the thoughts on how to remediate these areas vary from country to country. I am really happy that Sweden is choosing thermal in situ remediation where it is best suited.”
Other countries and remediation projects are looking to see what Teckomatorp and the BT Kemi-project is doing to clean its contaminated soil. Among these are the projects working with the Bhopal gas tragedy in India and the military airfields of Vietnam contaminated by Agent Orange. Dr Bruce McGee is also spreading the word.
“I will tell anyone who wants to listen about what happened – and is happening – in Teckomatorp. Because the thing I love more than a good story is a great ending. And we are hoping to contribute with that.”
