1. Roxana Marsh Characterization by Jim Smith, Ph.D., IDEM & Dan Sparks, U.S. FWS

2. Roxana Marsh Characterization Purpose - To determine the chemical, physical and toxicological characteristics... Goals - Collect data of sufficient quality and quantity to: –Determine if Remediation is required; –If Remediation is required, have sufficient data to make decisions on scope and extent; –Develop Restoration Plan for Marsh

4. Scope of Work for Characterization of Roxana Marsh Grand Calumet River Restoration Fund Council August 2001

5. Roxana Marsh Characterization Review of Previous Sampling and Analyses HNTB, 1989,1991 - probes of marsh give rough estimate of sediment depth and volume; URS Greiner Woodward Clyde, 1999 - Surface & Core samples for Chemistry & Toxicity

7. Sampling Surficial and Core Sample - maxium of 60 samples from up to 20 locations Utility Survey to identify pipelines, utilities Field Sampling & Analyses Plan –Sampling, Health & Safety, Quality Assurance/Quality Control

8. Characterization - Horizontal & Vertical Control - Chemical Analyses –Analyses for PCBs, Organochlorine Pesticides, PAHs, Mercury, Metals, Oil & Grease, Total Organic Carbon, Acid volatile sulfides/simultaneously extracted metals, grain size –Reporting Limits –QA/QC Requirements

9. Characterization - Toxicity Analysis –28-day survival and growth test using Hyalella azteca (or other appropriate organism) –USGS, BRD Columbia, Mo - Data Validation - Reports, Schedules, Coordination
