Proposed Project Reaches and

Past Sample Points

Burton & Dorkin, 1994

Data Gap 1Bathymetric / Topographic Survey

• Establish Riverbed Topography & Core Sample Elevations

• Develop Remedial Alteratives & Establish Dredging / Capping Quantities

• Assess Potential Disposal Sites

• Evaluate Potential Access to River

• Aid in Preparation of Final Restoration Plans

Data Gap 2Need Engineering Base Drawings

• Historical Sampling Locations

• Proposed Sampling Locations

• Show Contaminated Sediment Sections

• Lay Out Preliminary Dredge / Capping Prisms & Materials

• Preliminary Locate & Lay Out Access Sites & Potential Disposal Areas

Data Gap 3 Transfer Sediment Core Data to Base Drawings

• Calculate (X,Y,Z) Sediment Core Data Locations Based on Bathymetric

Survey

• Place Data on Base Maps

Data Gap 4 Proposed Additional Core Boring,

Sediment Chemical / Physical Properties

• Between Indianapolis Blvd & White Oak

• Between White Oak & Columbia Ave.

• Between Columbia Ave. & Calumet Ave.

• Between Calumet Ave & Sohl Road

• Between Sohl Road & Hohman Ave.

• Between Railroad Bridge & State Line

Proposed Sampling

Data Gap 5Need Information on Access Sites

• Very Shallow Water

• Limited Access and Bank Stability for Equipment Insertion, Dewatering, Hauling

• Bridges have no Horizontal or Vertical Clearance for Equipment Movement from River Reach to River Reach

Data Gap 6Local Sources of Services & Material

• Information is needed on:– Local Labor– Dredging Equipment– Construction Equipment– Fleet Vehicles– Aggregate & Sand– Concrete– Related Services

What’s Next

• Do we Proceed with Phase 2?

• Do we do all proposed sampling or reduce number?

• Are all parameters identified?

• Should we do additional Toxicity Sampling?

• Do we obtain New Aerial Photos to develop topographic base maps or can we use some flown in 1994 or 1995?
