The Reilly Tar and Chemical operated a coal tar and wood processing plant on a 80 acre site from 1917 until plant closure in 1972. Reilly disposed of wastewater from the operation in a network of ditches which discharged into a swampy area south of the Reilly site. The contamination from these sources has migrated downward into the groundwater, contaminating the shallow aquifer underlying the site. Through multi-aquifer wells the contamination has entered deeper aquifers including the Prairie Duchien-Jordan aquifer. Ongoing pump and treat operations are not viewed as ecologically or economically sound long-term solutions. All parties agreed that programs to eliminate polluting materials at the source to speed the cleanup process and minimize the potential leakage of the pollutants into interconnected aquifers is desirable. In this connection, a study was completed to examine whether source materials can be eliminated by on site and/or in situ bioremediation. In order to engineer a bioremediation strategy which optimizes degradation rates it is extremely important to determine the rate limiting steps in the treatment process. The results of this study show that if sufficient oxygen can be provided, in situ bioremediation could be effective at reducing or eliminating offsite pollutant migration and effectively remove the sources of the groundwater contamination.
