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

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

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
