• Groundwater Scenario 1: Baseline Controls and Existing Purge Well System.
• Groundwater Scenario 2: Baseline Controls, Existing Purge Well System, and Two Additional Pump and Treat Systems.
• Groundwater Scenario 3: Baseline Controls, Existing Purge Well System, and Two Dual-Phase Vapor Extraction Systems.
• Site Scenario 1: Capping of Surface Soil in Former Small Disposal Pile Exposure Area.
• Site Scenario 2: Daramend® Bioremediation of Surface Soil in Former Small Disposal Pile Exposure Area.
• Site Scenario 3: Consolidation of surface soil from Former Small Disposal Pile Exposure Area and Daramend® Bioremediation.
• Site Scenario 4: On-site Thermal Treatment of Surface Soil from the Former Small Disposal Pile Exposure Area.
• Site Scenario 5: Off-site Incineration of Surface Soil from the Former Small Disposal Pile Exposure Area.
