Short description: he objective of this project was to develop and test a methodology to periodically assess and optimize remediation and monitoring strategies at sites affected by DNAPL where remedies are in place. Methods were developed to model cost and performance of source zone and dissolved plume remediation technologies—including thermal treatment, chemical oxidation, enhanced bioremediation, and reactive barriers—and to optimize system operation and monitoring to meet user-defined cleanup criteria with minimum life-cycle cost, considering uncertainty in performance predictions using a stochastic optimization approach. The capability of the Stochastic Cost Optimization Toolkit (SCOToolkit) developed under SERDP Project ER-1611 was greatly extended in this project. The previous 2D contaminant transport model was rewritten to simulate 3D transport with steady-state groundwater flow along linear or curvilinear streamlines with multiple DNAPL sources.
