Doe Run Water Treatment Program

During construction of a new industrial wastewater treatment plant for The Doe Run Company, Kienlen placed 2,100 cubic yards of structural concrete, installed 33 tons of clarifier equipment, and 600 pieces of miscellaneous metals. Doe Run operates mines throughout southeast Missouri that produce lead, copper, and zinc. The Environmental Protection Agency (EPA) issued a consent order for the treatment of mine runoff and waste at the site, which required the new plant to be constructed under a very aggressive schedule.
