What Are the Risks at the Site?

At each site, EPA determines the possibility for human and ecological contact (i.e., exposure) with contaminants at the site. EPA determines if the site poses a risk to humans, and if so, identifies actions that can be taken to control any possible exposure to humans until site cleanup has been completed. Once complete, cleanup provides long-term human health and environmental protection at the site. (Superfund risk assessment process)

The most recent Five Year Review was published by EPA HQs in 2018.

Risks and pathways addressed by the cleanup include health risks from people ingesting or touching contamination in groundwater, soil, surface water and sediment. Contamination resulted from waste handling practices at the site. EPA has addressed surface water, soil and sediment contamination at the site. In 1980, the Kentucky Department of Hazardous Materials and Waste Management installed a gas collecting, venting and monitoring system at the landfill to address air contamination. EPA also installed air monitoring stations in the residential area next to the site.

In June 2013, EPA sampled gases in the soil between the landfill and the residential community. Results showed that gases were migrating off the site, indicating that the gas collection and venting system is ineffective. In June 2014, EPA conducted vapor intrusion sampling in 33 nearby homes to determine whether the gases are present in the homes. The results indicated that homes near the landfill were not impacted by vapors from the landfill. Methane does not currently appear to be a threat.

Because of the age of the existing wells and the need for more extensive groundwater data, KDEP installed five new groundwater monitoring wells in April 2014. The result of the sampling events since the installation of the wells are available from KDEP. The access road to the site is gated and No Trespassing signs, indicating the site’s Superfund status, are posted along the site borders.

Performance Measures

EPA uses performance measures to track environmental results at Superfund sites. If you have any questions or concerns about the measures at this site, please contact the site team members listed under Site Contacts.

Status at this
Superfund Site
What does this mean?
Human Exposure Under Control Yes Yes means assessments indicate that across the entire site:
  1. There are currently no unacceptable human exposure pathways; and
  2. EPA has determined the site is under control for human exposure.

No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.

Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
  1. Response to the contamination has not begun; or
  2. The response has begun, but it has not yet generated information sufficiently reliable to evaluate whether there are currently any unacceptable human exposure pathways at the site.
Groundwater Migration Under Control Yes

Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.

No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.

Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.

Construction Complete Yes

Yes means the physical construction of the cleanup is complete for the entire site.

No means either physical construction is not complete or actions are still needed to address contamination.

Sitewide Ready for Anticipated Use No Yes means:
  1. All cleanup goals affecting current and reasonably anticipated future land uses of the entire site have been achieved, so there are no unacceptable risks;
  2. All required land-use restrictions or other controls have been put in place; and
  3. The site has achieved Construction Complete status.

No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
