      One cost-effective and practical approach to clean up contaminated aquifers that is attracting increased attention is the application of SRMs for a long-term contaminant removal and transport control. Because SRM application for site remediation is an in situ and passive technology, the operational and maintenance cost can be significantly : Chih-Ming Kao, Yih-Terng Sheu, Jiun-Hau Ou, Wei-Han Lin. My areas of research interest include the development of in situ remediation technologies for treating contaminated groundwater, chemical oxidation of organic contaminants, impacts of in situ remediation on aquifer quality, and the integration of treatment technologies for optimized risk reduction. Current projects focus on developing novel approaches for treating recalcitrant compounds such.

Considerable effort by the academic community is being. Better success has been found with the removal of volatile LNAPLs due to higher gaseous diffusivities, propensity for aerobic biodegradation, and ease of pumping and handling large quantities of gas.

The rate and magnitude of DNAPL removal is dependent upon site-specific and technology-specific factors. Field results have demonstrated that the efficiency of DNAPL depletion often decays. technologies for cleaning up contaminated sites were wildly optimistic. Original estimates, inprojected an average Superfund cleanup cost of a mere million per site and assumed only around sites would require remediation.
