In January, GSI will be well represented at the 2017 Battelle Conference on Remediation and Management of Contaminated Sediments in New Orleans.

Heidi Blischke

Heidi will have a poster about the degradation of organophilic clay in a sediment cap 11 years after placement. Her co-authors are GSI’s Erin Carroll Hughes and Sarah Miller of the Oregon Department of Environmental Quality (DEQ).

Rod Struck

Rod had four abstracts accepted—one poster and three presentations—each on various aspects of his work with the Astoria Marine Construction Company (AMCCO), a marine shipbuilding and maintenance facility in Astoria, Oregon:

One platform talk will discuss successful approaches to expediting a remedial investigation and feasibility study (RI/FS). Rod’s co-authors are Heidi Blischke and Madi Novak and Phil Wiescher of Maul Foster Alongi, Inc.

Another talk will cover effective ways to integrate natural resource damage assessments early in the RI/FS process and expedite the project schedule. Co-authors include Heidi Blischke and Ron Gouget of Windward Environmental.

A third talk will explore using background sediment concentrations to support risk-based decisions during the expedited RI/FS. Rod’s co-authors are Heidi Blischke, Madi Novak, and Phil Wiescher.

Rod’s poster will share lessons learned from using incremental sampling methodology (ISM) to characterize river sediments during the expedited RI/FS. His co-authors are Heidi Blischke, Madi Novak, and Phil Wiescher.

Erin Carroll Hughes

Erin also was accepted for a poster and a presentation:

Her presentation, with co-authors Heidi Blischke and Sarah Miller of DEQ, explores long-term sediment cap effectiveness monitoring using various passive sampling devices at the McCormick and Baxter Superfund Site in the Willamette River in Portland, Oregon.

Erin’s poster assesses landfill remedy requirements through the evaluation of porewater concentrations and ex-situ porewater bioassays from the Tualatin River. Her co-authors are Heidi Blischke, Cindy Ryals (a former GSI employee who now works for the City of Portland), and Robert Williams of DEQ.
