Pilot Region-Based Optimization Program for Fund-Lead Sites in EPA Region 3. Site Optimization Tracker: Crossley Farm Superfund Site Hereford and Washington Townships, Berks County, Pennsylvania:Final rept

摘要

Once hydraulic containment is established for the downgradient plume, source removal options should once again be considered. However, the optimization team cautions against expenditure on any source removal technology without a clear understanding of how the technology will hasten progress to site closure and without guarantees of performance from vendors. If the application of a technology will remove mass but not speed up site cleanup (because significant mass still remains as a continuing source of dissolved ground water impacts), then implementing that technology is of questionable value. Pilot testing should only be performed on aggressive source remediation technologies after an evaluation has been performed to determine that scale-up to full-scale implementation is feasible from a cost perspective.
