Plume Characterization Characterization <strong>of</strong> plume assumed to be complete • Seasonality known • Hydrology is known • Significant COCs known • Source areas known MAROS reveals broad trends; individual data points less significant 24
Uses Delaunay Triangulation Well Redundancy and Sufficiency Analysis Delaunay Method: - Eliminate “redundant” wells OR - Add wells in areas with high concentration uncertainty Source Zone Tail Zone KEY POINT: Does estimated concentration change if well is removed? 25
