Remediation Optimization
Application
Applications of Simulation/Modeling Optimization Technologies
Simulation optimization is the use of mathematical optimization techniques coupled with groundwater simulation models to determine optimal pumping locations and rates for plume containment and/or cleanup. There are two major categories, hydraulic optimization (based on groundwater flow models such as MODFLOW) and transport optimization (based on contaminant transport models such as MT3D).
Hydraulic Optimization
Hydraulic Optimization Demonstration for Groundwater Pump-and-Treat Systems
Hydraulic optimization allows all potential combinations of well rates as specific locations to be mathematically evaluated with respect to an objective function (e.g., minimize total pumping) and series of constraints (e.g., the plume must be contained). The hydraulic optimization code quickly determines the best set of well rates, such that the objective function is minimized and all constraints are satisfied. This project included a screening analysis to determine those sites that would most benefit from hydraulic optimization and demonstrated the use of hydraulic optimization software at multiple sites.

Transport Optimization
ESTCP Transport Optimization Demonstration Project
EPA co-sponsored this project with Environmental Security Technology Certification Program (ESTCP) and Naval Facilities Engineering Service Center (NFESC). The primary objective of the overall project is to demonstrate the cost benefit of applying transport optimization codes, which couple sophisticated optimization techniques (nonlinear programming) with simulations of groundwater solute transport. The demonstration project applied two transport optimization packages to three Department of Defense sites. Information regarding the objectives packages used, site models, and results are available.
