摘要： A heater for thermal conduction heating suitable for use in non-vertical heater wells for purposes of soil remediation. The heater includes a rigid bar to position a non-insulated heating element in the casing away from the interior surface of the casing.

摘要： A method and system to remediate soil containing PFAS compounds and organic carbon. Total organic carbon is reduced by heating the soil at a sufficient temperature and for a sufficient duration to reduce surface effects between the PFAS compounds and the organic carbon to permit evaporation and treatment of the PFAS compounds from the soil. A flexible helical heater is employed to heat the soil.
