SUSTAINABLE COMBINATION HEATING: AN INNOVATIVE APPROACH FOR IN SITU THERMAL REMEDIATION IN CHALLENGING LITHOLOGY
Dablow, J., M. Dawes, G. Mackey, D. Nelson, J. Baldock, and K. Schnell.
RemTech 2018: 10-12 October, Banff, Alberta, Canada. 22 slides, 2018
Two sites, one in California and one in Switzerland, were remedied using a combination of in situ thermal remediation technologies to mitigate source zone impacts in lithologies where relatively low-permeability silts and clays are underlain by high permeability sands and gravels. At the Switzerland site a mixture of high boiling point compounds leached from a landfill was treated via thermal conductive heating and steam enhanced extraction (SEE) to achieve stringent concentration-based remedial goals. The estimated total mass removed in Switzerland was ~6,200 kg, of which ~75% comprised TCE and o-DCB. At the California site, a combination of electrical resistance heating and SEE was applied in November 2017 at a former manufacturing site contaminated by chlorinated solvents. Remedial goals were met in May 2018.
