  1. Draft Work Plans West Branch of the Grand Calumet River Indiana September 2002 prepared by Foster Wheeler Environmental Corporation for Grand Calumet River Restoration Fund Council

  2. Restoration Alternatives Development and Evaluation West Branch Grand Calumet River

  3. Results of Phase I Technical Memorandum Restoration Alternatives Development and Evaluation West Branch Grand Calumet River January 2002

  4. 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?

  5. 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

  6. 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

  7. Proposed Sampling

  8. Proposed Reach 1 Transects

  9. Proposed Reach 2 Transects

  10. Proposed Reach 3 Transects

  11. Proposed Reach 4 Transects

  12. Proposed Reach 5 Transects

  13. Proposed Reach 7 Transects

  14. 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

  15. Additional Sampling Activities • Fish Community and Tissue Sampling • Invertebrate Community • Date being collected for potential use in Human Health & Ecological Risk Assessment
