William Cretens, President and CEO of IAI, has recently had two technical papers published. The papers each present a case study of the Ashtabula River Remediation project, in which the geotextile tube (Geotube®) dewatering process was used to dispose of hydraulically dredged contaminated river sediment. The two papers were originally presented at national conferences in February 2009.
Bill presented his paper, Ashtabula River Remediation Combines Contaminated Sediment Removal with Navigational Dredging with co-author Paul Olander of J.F. Brennan Company at the Fifth International Conference on Remediation of Contaminated Sediments in Jacksonville, Florida on Feb. 4, 2009. (Mark Binsfeld of J.F. Brennan Company also co-authored the paper.) This paper highlights Phase II of the Ashtabula River Remediation project, which removed contaminated sediment from the Ashtabula River to restore depth in the federally-authorized navigation channel and was published in the conference proceedings.
Bill’s second paper about the project, Geotextile Tube Dewatering Technology Utilized on Massive Scale in Ashtabula River Remediation was presented at the GeoSynthetics 2009 conference in Salt Lake City, Utah on Feb. 26, 2009 and was published in the conference proceedings. This paper focuses on the challenges of dewatering more than 600,000 cubic yards of contaminated sediments in geotextile tubes (Geotube® containers) and how the remediation team accomplished this task successfully.
