Site Background:
The Tri-City Disposal Company operated a 57-acre landfill at this 349-acre property between 1964 and 1967. Highly volatile liquid wastes, lumber scraps, and fiberglass insulation materials from various Louisville area industries were disposed of at the landfill. A 1968 aerial photograph suggested that several hundred drums were buried and several others were stored above ground on the site. In 1987, the State determined that groundwater and soil samples from the site indicated organic compounds due to the landfill. Two springs were contaminated with volatile organic compounds. A tributary of the Brushy Fork Creek was contaminated with heavy metals such as lead, chromium, and mercury. Site soils indicated contamination with polychlorinated biphenyl, heavy metals, creosote and various organic compounds. Approximately 1,600 people obtain drinking water from springs and wells within 3 miles of the site. A portion of the site is used for agricultural purposes such as pastures and gardens. All surface drainage flows south where it enters the Brushy Fork Creek which supports livestock, agriculture and recreational activities.

Cleanup Progress: Construction Completed
EPA initiated an emergency response action at the site in 1988. Three area families were immediately provided an alternate water source. Drums of waste and contaminated soils were excavated and transported for proper disposal offsite. Following the completion of site studies, EPA selected a final cleanup strategy in 1991, and issued the potentially responsible parties (PRPs) a unilateral order to implement the Remedial Action (RA).   Remedial Design was accomplished in 1992, and construction of the remediation facilities was completed in June 1994.  Two affected springs are remediated concurrently using two systems of granular activated carbon adsorption beds.  The treated water is discharged back into the springs.  The third spring requiring attention is not treated due to low health risk posed by the water but it is enclosed in a chain link fence to limit access to the affected portion of the water.  Long-term monitoring of the site required as part of the cleanup is in progress.  Samples of the three affected springs are taken periodically to track the concentrations of the contaminants in the springs.
