Pumping Optimization Model for Pump and Treat Systems Steve Baker: Umtanum Enterprises Flow and Transport by SSPA Data and Analysis by CHPRC
Background The Hanford Site is near the Columbia River in Washington State Nuclear Reactors were Operated to Produce Plutonium for Weapons Reactors Located Near the River for Cooling Water Access Operations Resulted in Significant Groundwater Contamination Pump and Treat Selected for Remediation Hexavalent Chrome Contamination a Major Concern
Pump and Treat Well Locations and Rates
Pumping Optimization Model: Scope This Presentation Deals With Analysis and Display Two Other Presentations Deal With Data and Design 15316: Development of a Groundwater Transport Simulation Tool for Remedial Process Optimization – Session : Innovative Use of Cr(VI) Plume Depictions and Pump-and-Treat Capture Analysis to Estimate Risks of Contaminant Discharge to Surface Water at Hanford Reactor Areas – Session 135
Pump and Treat System Design 3D Groundwater Flow &Transport Model Created to Support Design Many Simulations Required to Optimize Design 2D Equivalent-Property Model Derived From 3D Model 2D Model Linked to User Interface to Simplify Operation Combined System Called the “Pumping Optimization Model (POM)” Short POM Run Times Support Optimization
Pumping Optimization Functionality Two Major Components Graphical User Interface Flow and Transport System MODFLOW MT3D Support Utilities
