From 1964 to 1967, the Tri-City Disposal Company operated a 57-acre landfill at this 349-acre property in Shepherdsville, Bullitt County, Kentucky. 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 ground water 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 including lead, chromium, and mercury. Site soils indicated contamination with polychlorinated biphenyls (PCBs), heavy metals, creosote, and various organic compounds.
Approximately 1,600 people obtain drinking water from springs and wells within three 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.
Site Cleanup Plan
The cleanup plan for the Tri-City Disposal Company site covered two operable units (OUs): OU-1 (ground water) and OU-2 (additional measures to mitigate threats from contamination).
The Record of Decision (ROD) for OU-1 was issued in 1991. Major elements of the cleanup plan included:
- Institutional controls to restrict the potable use of ground water containing, or potentially containing, levels of contamination in excess of Maximum Contaminant Levels (MCLs) and non-zero Maximum Contaminant Level Goals (MCLGs).
- Continued provision of potable water to residents who previously used contaminated ground water as a source of potable water. Water will be supplied until EPA determines that the water is of sufficient and consistent quality for human consumption.
- Long-term monitoring of the ground water, surface water, sediment, and ecology. Since the on-site springs have been historically used for potable water, monitoring is proposed to ensure that contaminant levels remain below MCLs and non-zero MCLGs. If treatment of any of the on-site springs is determined to be necessary, it will be included in OU-1. Additional measures necessary to mitigate the threat to the environment will be implemented in OU-2.
- Surface soil sampling to assess whether the emergency removal action conducted near the Cox, Sr. Residence was effective. Additional sampling of sediments will be used to determine the extent of contamination and air sampling will be conducted to identify the source of PCB contamination detected in the remedial investigation.
- Treatment of the contaminated water in the Cox spring with a carbon adsorption system. The treated water will be discharged to the downstream tributary in accordance with National Pollutant Discharge Elimination System standards.
The ROD for OU-2 was issued in 1996. Based on the results of additional sampling, monitoring reports, and risk evaluation, the decision was made that no further remedial action is necessary at the site to ensure protection of human health and the environment.
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 off site.
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 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.
As part of long-term monitoring requirements, samples of the three affected springs are taken periodically to track the concentrations of the contaminants in the springs.
Site cleanup activities are being led primarily by potentially responsible parties (PRPs) with oversight by EPA.
In 1992, EPA issued the PRPs a Unilateral Administrative Order to fund and implement the Remedial Design and Remedial Action required by the OU-1 ROD.
EPA has conducted a range of community involvement activities at the Tri-City Disposal Company site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices and interviews.
The next FYR is due by 2013.
Cleanup activities will continue at the site until the concentrations of contaminants in certain impacted springs no longer exceed remedial goals.
