This report evaluates data from sediment and benthic toxicity investigations conducted for the Lower Rouge River (LRR) in Detroit, Wayne County, Michigan. Specifically:

• Hot Spots 1 through 6 (HS-1 though HS-6; excluding HS-2)
• the Zug Island Channel
• the area near Outfall 2
• the area near Outfall 17
• the West Jefferson Street Bridge and O’Brien Creek

The primary goal of the sediment investigation was to gather additional sediment chemistry data and sediment toxicity data to further delineate the spatial extent and magnitude of sediment contamination impacting aquatic life within the LRR.
