The Ogallala Ground Water Contamination Superfund site was identified in 1989 through municipal well sampling. Tetrachloroethene (PCE), a solvent commonly used in dry cleaner operations, was the primary ground water target chemical of concern (COC) that was identified for remediation purposes. A comprehensive remedial investigation (RI) was conducted in 1995 and 1996. Additional investigations were also conducted following completion of the RI to define the plume.
