Habitat Characterization/Sediment

Thickness

• Evaluation of potential reference areas

– Grassy Creek just downstream of Elm Street

in Perrysburg, Ohio

– Amolsch Creek downstream of Dustin Road in

Oregon

• Qualitative evaluation of land use and

habitat character

• Sediment thickness – on-going

Duck and Otter Creeks Data Gap

Investigation – Next Steps

• Analytical, toxicological and biological data

should all be in by end of the year

• EPA’s contractor is building a database of

the results

– Includes data validation/usability evaluation

Duck and Otter Creek Industrial Partners

will:

– Evaluate the data and

– Prepare draft report of investigation

Next Steps

• Chemical and toxicological results –

January 2011

• Data validation/usability assessment

• Report – spring 2011

• Determine where to go from there

• Additional sampling spring 2011 likely
