Union Carbide Corporation was responsible for the Remedial Design/Remedial Action after the proper remediation techniques were recommended, and funded the cleanup efforts almost entirely (EPA 1988).Following its pre-design activities UCC also agreed to evaluate the results of its remedial actions and to improve the system if evaluations deemed it necessary (UCC 2003). An initial phase of groundwater and soil sampling took place in 1991 and was followed by a study to determine remediation costs and whether or not a thermal desorption treatment would be viable (UCC 2003).The results of this study lead to changes in the remediation plans which determined a Parkway well field would be used for groundwater treatment, rather than relying on a process where groundwater would be treated directly beneath the Reich Farm site and then transported up gradient from the site (UCC 2003).This change was the result of the EPA’s conclusion that groundwater contamination extended to a Parkway well field located one mile south of the Reich Farm Superfund site (UCC 2003).Another change to the plan was the decision to ultimately use the treated water from this Parkway well field as a municipal water supply, rather than transporting it back into the ground water supply up gradient (UCC 2003).
