  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

  3. Scope of WorkforCharacterization of Roxana Marsh Grand Calumet River Restoration Fund Council August 2001

  4. 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

  5. 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

  6. 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

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

  8. Field and Laboratory Data Report Chemical, Physical and Toxicological Characterization of Roxana Marsh Grand Calumet River Basin East Chicago, Indiana September 2002

  9. PCB Levels
