Thermal remediation methods include hot water flushing, steam flushing (SF), electrical resistance heating (ERH), and thermal conductive heating (TCH). To date, there has been little research conducted on thermal remediation in highly heterogeneous subsurface systems (e.g. Smithville fractured rock site), either at the lab or field scale, or with numerical modelling. Prediction of rate limited mass transfer associated with the removal of multicomponent nonaqueous phase liquids (NAPL) by thermal remediation, particularly NAPL containing both high and low volatility organic compounds is also not currently well understood.

热修复方法包括热水冲洗、蒸汽冲洗（SF）、电阻加热（ERH）和导热加热（TCH）。迄今为止，无论是在实验室还是现场规模，还是在数值模拟方面，对高度非均质地下系统（例如Smithville断裂岩石场地）的热修复进行的研究都很少。热修复法去除多组分非水相液体（NAPL）的速率有限传质预测，特别是同时含有高挥发性和低挥发性有机化合物的NAPL，目前还没有得到很好的理解。
