IMPORT ANT REASONS FOR CHANGING
CURRENT STRATEGY
• Field Testing of Small Amounts of Site \Vaste will not
Provide Information that is more Useful than Bench-Scale
Testing
• Costs of T\\'O Field Tests \Vould be Extremely High
• It is Necessary to Examine Other Detoxification
Technologies
• Current Approach Would not Provide Sufficient Detailed
Information
• A Much Stronger Case for Funding can be Made by
Spending Money on More Thorough Site Investigation
and Remedy Design
KEY STEPS OF RECOMMENDED
ALTERNATIVE STRATEGY
• Detailed Evaluation of Detoxification Technologies and
Vendors
• Initiate Site Investigation
• Design Soil/Waste Removal Plan/Select Vendor
• Issue Feasibility Study Report
• Invite Vendors to Conduct Bench-Scale Treatability Tests
• Science Advisors Evaluate Test Results and Select/Rank
Vendors
KEY STEPS OF RECOMMENDED
ALTERNATIVE STRATEGY
(Continued)
• Finalize Site Investigation Report
• Working Group Meeting with Highest Ranked Vendors
• Best Technology Vendor Selected/Pre-Qualified for Actual
Cleanup
• Selected Vendor -is Hired as Design Contractor (Under
Current Funding)
• Remedy Selection and Remedial Design Report
• Report used as the Basis for Working Group/DEHNR
formally Proposing the Landfill Detoxification Project to
the State Legislature to Obtain Funding
SITE INVESTIGATION GOALS
• Establish Condition of Liner
• Bedrock Condition and Topography
• Transmissivity of Weathered Rock Zone
• Direction of Ground'\\·ater Flo"'
• Identification of Contaminant Plume
• Types and Amounts of Contaminated Media Reguiring
Clean-Up
SITE INVESTIGATION ACTIVITIES
• Collection of Samples to Conform with Permit
Requirements
• Analyze Existing Data
• Develop and Implement Field Sampling and Testing Plan
• Non-Intrusive Testing (Geophysics)
• Soil Borings
• Installation of Additional Monitoring Wells
• Collection of Additional Surface Water and Sediment
Samples
