The Southwest Jefferson County Mining site is located in the southeastern portion of Missouri and is considered part of Missouri's "Old Lead Belt."
The Southwest Jefferson County Mines Superfund site has a signed Record of Decision for remedial action, but it does not currently address residential properties with lead concentrations between 200 to 399 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.
This Removal Action included the excavation and disposal of lead-contaminated soils from residential properties and followed procedures described in the Superfund Residential Lead Sites Handbook.
