Partnering companies purchased a 19-acre parcel in Ashtabula Township for a Sediment Consolidation Facility to store contaminated sediments from the riverbed, and the facility was completed in 2006. State and federal agencies dredged the Ashtabula River between 2006 and 2011, removing over 700,000 cubic yards of contaminated sediment, reopening the river for commercial shipping and recreational boating, and pumping the material into a specially designed landfill where it was isolated from the environment. Restoration of the Ashtabula River began in 2008, creating about 2,500 feet of fish shelves and a total of 10.5 acres of river, wetland, and upland habitat for mammals, birds, and fish. With funding from the U.S. EPA, U.S. ACE, industry, and the State of Ohio, approximately 700,000 cubic yards of contaminated sediment were removed from the river between 2006 and 2008 and pumped uphill through a 2.5 mile pipeline to an upland sediment containment facility and into geotextile tubes that separated contaminated sediment from slurry water, as the Hash-tah-buh-lah River returned toward its former glory as a river of many fish.
