Steam injection for in-situ remediation of DNAPLs in low permeability media
- Univ. of Toronto (Canada)
The potential for remediation of dense, nonaqueous phase liquid (DNAPL) contamination by steam injection is investigated, including the advantages and disadvantages of the technology. The primary advantage is the significant enhancement of removal rates through steam distillation. The disadvantages are related to the lack of field experience with the technology and difficulties related to steam override and channeling in heterogeneous soils. The problems related to steam injection in low permeability fractured clay are examined, and removal times and costs are postulated for a hypothetical DNAPL contamination scenario. It is concluded that steam injection has significant potential for remediation of DNAPL in fractured clay soils, but there is significant uncertainty in predictions of the performance of steam injection in these soils. 13 refs., 4 figs., 1 tab.
