The Union Pacific Railroad (UPRR) Tie Treating Plant is located southwest of Laramie, Wyoming. Wood preserving agents used by UPRR or its contractor included: zinc chloride, a creosote oil and asphalt-based petroleum/residuum oil mixture, PCP. Process wastes were disposed of in the Laramie Waste Collection ponds. Currently, 140 acres are contaminated. The contamination ranges from soil saturated with free oil to ground water containing dissolved contaminants. The selected interim source control remedy is a Contaminant Isolation System which includes: realignment of the Laramie River channel; a soil-bentonite slurry barrier wall constructed through the alluvium and bedrock around the contaminated areas; a reverse-gradient ground water draining and pumping system; an activated carbon water treatment plant. The treated water will be discharged to the Laramie River under the authority of an NPDES permit issued and administered by the State of Wyoming; and ground water monitoring.
