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 Workfor

Characterization of Roxana Marsh

Grand Calumet River Restoration Fund Council

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/simultaneously extracted metals, grain size

– Reporting Limits– QA/QC Requirements

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
