U.S. EPA on-site to remediate mercury found at 6211 Applegate Lane

August 29, 2023

There remains no risk to the general public; air monitoring continues

Professionals from the U.S. Environmental Protection Agency (EPA) returned to Louisville this week to safely remediate mercury found at 6211 Applegate Lane. The mercury was initially found inside and outside the home (within the fenced area) during EPA’s visit to Louisville the week of August 14, 2023. A final decision has not yet been made on the best and safest path forward to remediate the property at 6213 Applegate Lane.

“Both Applegate Lane houses remain secure and are under constant surveillance. Our administration continues to plan for a monitored and controlled burn of 6213 Applegate Lane,” said Mayor Craig Greenberg. “We will provide an updated timeline as soon as possible. We’re grateful to have our state and federal partners, including the U.S. EPA, as part of the Unified Command and we look forward to working with them to resolve this situation safely.”

EPA is coordinating with Kentucky Emergency Management and the Kentucky Department for Environmental Protection for on-site cleanup operations. The removal of the mercury is expected to take three days; restoration could take several weeks and is dependent on contractor schedules. A portion of Applegate Lane, adjacent to the home, will be restricted to local access only during the hours of the cleanup operations.

The property remains fenced, secured and under 24-hour surveillance by Louisville Metro Police.

Air monitoring performed by EPA and Louisville Metro determined the mercury concentrations inside the building are over EPA’s and Centers for Disease Control and Prevention’s (CDC) health risk levels. These elevated concentrations are limited to inside the building and do not present health risks to persons outside.

The cleanup operations at 6211 Applegate Lane will include the removal of the concrete driveway, removal of interior items like furniture and carpet, and cleaning the tile/linoleum flooring with a sulfur compound and special vacuum.

EPA will test surfaces and air for cleanup efficacy. The goal is for mercury detections to be below 1000 ng per cubic meter. EPA will continue the remove/test cycle until the indoor air meets the cleanup goal. Once that goal is met, restoration of carpet and concrete will begin.

Residents with general questions about potential health effects of mercury exposure should call Kentucky Poison Control at 1-800-222-1222.
