NEWTON COUNTY MINE TAILINGS

MO | EPA ID MOD981507585

Human exposure is NOT currently under control

About this site’s exposure pathways: As of April 2025, the Newton County Mine Tailings Superfund site is considered 'Current Human Exposure Not Under Control' because recreational users and residents of the mine waste areas and impacted surface water can be exposed through direct contact to lead, zinc, and cadmium contaminated soils and sediments. The planned activities to address these pathways are the continuation of ongoing remediation of contaminated soils and sediments. Several EPA and PRP performed removal and remedial actions have been completed throughout the site. Remedial actions began in 2014 in the Granby sub-district. Previous and ongoing removal actions completed the residential and groundwater actions. Ongoing work is being conducted throughout the Granby, Spring City/Spurgeon, and Wentworth sub-districts, with future efforts planned for additional sub-districts. Human Exposure is expected to be under control by December 31, 2030, with Long-Term Human Health Protection estimated to be achieved by the same date.
