EPA R7 is conducting a Time-Critical Removal Action at the Oronogo-Duenweg Mining Belt site (Site) near Joplin, Jasper County, Missouri, starting in June 2024. This response action will address up to thirty (30) residential properties referred to the U.S. Environmental Protection Agency by the Missouri Department of Health and Senior Services (MDHSS). An assessment of these properties performed by the EPA Remedial Program in FY2023  identified elevated lead soil concentrations and confirmed the presence of sensitive populations.

The Site is divided into five Operable Units (OUs) for cleanup activities. The Time-Critical Removal Action will take place administratively within OU3 of the Site. The objective of this removal action is to reduce the risk and/or prevent the exposure of sensitive populations through inhalation, dermal contact, and/or ingestion to lead and/or other heavy metals present in the soil at the Site. The removal / risk reduction actions will involve the excavation and removal of lead-contaminated soil exceeding the RML of 200 mg/kg, and outreach activities (education and EBL testing) conducted by the local health department.
