Duquesne
The waterways in Duquesne are the Monongahela River, Nine Mile Run, and Thomson Run.
The City of Duquesne, incorporated in 1891, is characterized by its hills, floodplains and industry. Duquesne Works was an active steel mill in the 1900's with the largest blast furnace in the world. The Works produced steel rails in a twelve-furnace open hearth plant that continued to expand until its closing in 1984. It has since become a host for the Greater Pittsburgh Community Food Bank. The mill dumped extensive amounts of blast-furnace slag and waste into the nearby Nine Mile Run, which became the subject of U.S. Army Corps of Engineers restoration funds in the early 2000's. Thomson Run is considered ‘impaired’ by the PA Department of Environmental Protection, and it was found that the high metal content from Acid Mine Drainage harms aquatic life.
In case of an emergency (ex. major spill, threat to human and/or wildlife), call 911
