What’s Next • Do we Proceed with Phase 2? • Do we do all proposed sampling or reduce number? • Are all parameters identified? • Should we do additional Toxicity Sampling? • Do we obtain New Aerial Photos to develop topographic base maps or can we use some flown in 1994 or 1995?
Sampling and Analysis • Sediment Chemicals of Concern • PCB Aroclors & Congeners • Organochlorine Pesticides • Semivolatile Organics • Metals (RCRA) • Oil & Grease • Total Organic Carbon • Acid Volatile Sulfides - Simultaneously Extracted Metals
Sampling and Analysis • Utility Survey • Establish Horizontal & Vertical Controls • Bathymetry Survey • Topographic Survey • Sediment Geotechnical Sampling • Grain Size; Atterburg Limits; Specific Gravity; Moisture Content/Bulk Density; Triaxial Shear;Consolidation; Direct Shear; Column Settling; Elutriate Test; Modified Elutriate Test
Sampling and Analysis • Surface Water Testing • for use in Column Settling and Elutriate Tests • 4 samples tested for: PCBs; Organochlorine Pesticides; Semivolatile Organics; RCRA Metals; Dissolved and Total Organic Carbon; Total Suspended Solids • Bioassay Testing • 42 (+) samples analyzed by USGS
Additional Sampling Activities • Fish Community and Tissue Sampling • Invertebrate Community • Date being collected for potential use in Human Health & Ecological Risk Assessment
