EPA Region 7 referred this site to the Missouri Department of Natural Resources (MoDNR) in 2008 with a decision of no further remedial action planned, following a Resource Conservation Recovery Act (RCRA) closure investigation. MoDNR's Environmental Remediation Program was made aware of the potential threat to health in children and adults occupying the site in August of 2022, and immediately requested the EPA Region 7's assistance in assessing the site for a Removal Action to address Pentachlorophenol (PCP)-contaminated soils and liquids at the site in concentrations exceeding the residential risk management level of 100 ppm.
EPA conducted field sampling activities in November 2022. EPA collected surface soils in the proximity of former wood treating operations and representative samples of a sawdust and wood shavings waste pile. Liquid samples were taken from a storage tank found on the property. Water and sediment samples were taken from standing water found on the site, an adjacent spring, and a neighboring creek that flows to the east of the site.
EPA oversaw the removal of 1,500 gallons of liquid containing roughly 3.3% PCP, 74% diesel fuel, and 22.7% water, and the removal of 4,000 tons of PCP-contaminated soil.
There are currently no further EPA actions warranted at this time.
