[email protected] Abstract The Pittsburgh District has been authorized by Section 312 of the Water Resources Development Act of 1990 to remove and remediate contaminated sediments present within the Mahoning River that flows through the City of Youngstown and surrounding communities in Mahoning and Trumbull Counties, Ohio. The lower Mahoning River is one of the most heavily contaminated rivers in the United States. For much of the 20th Century, the river was used by numerous steel and related industries as a water supply source as well as an unregulated sewer to dump tons of waste materials. Since the downturn of the local steel industry in the 1980’s and 1990’s, water quality within the lower Mahoning River began to improve, but past industrial contamination has persisted within sediments deposited along the banks and river bottom.
