"The Welland River Reef Cleanup Project comprised the removal of two contaminated sediment deposits (reef formations) in the Welland River. It was undertaken by Atlas Specialty Steels (Atlas) of Welland, Ontario, a division of Sammi Atlas Inc. The reef formations were located in the Welland River in Welland, close to the Atlas plant and were primarily associated with two specific sewer outfalls, the McMaster Avenue and Atlas 42-in. outfalls. The reef materials consisted of industrial mill scale (granular, metallic particles) and solvent extractable contaminants (oil and grease) released by Atlas and other sources into the river over a period of 50 to 60 years, prior to the 1980s. In total 9833 m3 of reef materials were removed from the Welland River. The project also included the removal of approximately 1215 m3 of mixed coarse mill scale and sediments from the floodplain downstream from the Atlas 42-in. outfall"--Summary, volume 1, page [S-1].
