Lead was likely distributed throughout Viburnum during decades of mining, milling, and transporting of lead ores and concentrates. The site is in the city of Viburnum in southeastern Missouri. It is part of what is commonly known as the "New Lead Belt Mining District," or the "Viburnum Trend," where lead production began around 1960.
In December 2021, the EPA issued a Unilateral Administrative Order (UAO) to Doe Run Resources Corporation to conduct lead cleanups at residential properties at the Viburnum Trend Lead Haul Roads site. Currently, the selected cleanup level specified in the UAO and associated project documents is 400 parts per million (ppm) and does not address lead-contaminated yard cells above the EPA revised Removal Action Level of 200 ppm and below the UAO cleanup goal of 400 ppm.
This Removal Action will address residential properties referred to the Removal Program in August 2024 by EPA Region 7's Remedial Program due to the presence of lead between 200 and 399 parts per million (ppm) and the potential for lead exposure to a sensitive population at the residence.
The planned Removal Actions will include the excavation and disposal of lead-contaminated soils from residential properties and will follow procedures described in the Superfund Residential Lead Sites Handbook.
