Application of Flow and Transport Optimization Codes to Groundwater Pump-and-Treat Systems
Abstract
This Environmental Security Technology Certification Program (ESTCP) project evaluated the benefits and utility of applying transport optimization algorithms, operable on desktop computers, versus a traditional trial-and-error approach. The focus was on groundwater pump-and- treat (P&T) systems. The transport optimization algorithms link mathematical optimization techniques with simulations of groundwater flow and contaminant transport to determine the best combination of well locations and pumping rates for a P&T system. These mathematical algorithms can contribute to long-term operating cost reduction and/or improved performance of these systems with respect to compliance objectives (e.g., achieve cleanup standards in less time). Remediation system evaluation (RSE) or remedial process optimization (RPO) provides a broad assessment of optimization for the remedial systems, including system goals and exit strategy, below-ground performance, above-ground performance, monitoring and reporting, and potential for alternate technology. The pumpage optimization (as demonstrated in this project) is a subset or a component of these more general optimization evaluations for cases where P&T is expected to be a major component moving forward. The pumpage optimization impacts subsurface aspects of the remedy (e.g., cleanup time and containment) and in some cases also impacts above-ground aspects (treatment plant size/flow rate and influent concentrations) and possible monitoring requirements.
