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

Scope of WorkforCharacterization 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

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/simultaneou
    sly 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
