PUBLIC HEALTH ASSESSMENT

RUBBERTOWN INDUSTRIAL AREA
JEFFERSON COUNTY, KENTUCKY



CONCLUSIONS

On the basis of available information, ATSDR concludes that the Rubbertown industrial area poses an indeterminate public health hazard. ATSDR cannot draw conclusions about air and soil contamination because the representativeness of available data are uncertain and the length of time people may have been exposed to detected contaminants is unknown.

While exposures to dioxin contaminated sediment and fish may have occurred in the past, the site-specific exposures are not likely to result in adverse health effects. Because of the absence of current exposures to surface water, sediment, fish and groundwater, these media are not of health concern.


RECOMMENDATIONS

  1. Evaluate air data from the air toxics sampling and other site-related environmental projects when the data become available.

  2. Expand soil characterization to include metals (especially lead), organic compounds, and polycyclic aromatic hydrocarbons.

  3. Continue to educate the public (including local public health officials and the local medical community) of the ongoing health assessment efforts related to the Rubbertown site.

PUBLIC HEALTH ACTIONS

The actions described in this section are designed to ensure that this public health assessment identifies public health hazards and provides a description of current and planned activities to mitigate and prevent exposures.

A. Actions Implemented

Various community and government initiatives have been initiated to address environmental health concerns in West Louisville. The West County Community Task Force (WCCTF), established by the Jefferson County Division of Environmental Health and Protection, includes residents, industry representatives, and local government agencies. The mission of the task force is to identify and address community environmental concerns and environmental health concerns (WCCTF, undated). EPA Region 4 has initiated a Community-Based Environmental Protection (CBEP) program in West Louisville. Through this program, EPA Region 4 will work with the West Louisville community to "facilitate a reduction in human health and ecological risks, improve environmental conditions and enhance the community's quality of life" (EPA, 1998). ATSDR has participated in meetings with both the WCCTF and the EPA to assist in addressing community and environmental concerns.

B. Actions Planned

Air toxics monitoring is scheduled to begin soon in West Louisville. The budget recently passed by the Kentucky General Assembly for the fiscal year beginning July 1 includes funding for a collaborative monitoring effort to be conducted by the JCAPCD, the city of Louisville, the University of Louisville, and the WCCTF. Project leaders hope to begin monitoring sometime during the winter of 1998-1999 (Barnett, 1998). In addition, a key component of the EPA CBEP program will be an air toxics monitoring study beginning in the summer of 1999 (ATSDR, 1998). Also, the city of Louisville will be conducting a "Metro Parks Lake and Pond Dioxin Study", funded by the Kentucky General Assembly. This investigation will involve analysis of fish and sediment samples collected from 10 city park lakes over a 2-year period, beginning in September 1998. This effort is designed to compare and evaluate dioxin concentrations, and to provide this information in a report to the WCCTF. The city has also been directly involved in follow-up investigation at Chickasaw Lake to further monitor for the presence of dioxins in fish tissue and sediments originally discovered in 1995. ATSDR will continue to participate in meetings with both the WCCTF and the EPA to assist in addressing community and environmental concerns. ATSDR will evaluate additional environmental data for public health significance when the data become available and provide all interested parties with a report of the agency's findings.
