Summary

Administrative Record Available for Time-Critical Removal Action

Contaminated Soils at Residential Yards and Child High-Use Areas

The U.S. Environmental Protection Agency (EPA) Region 7 has compiled the Administrative Record (AR) file for a Time-Critical Removal Action in Jasper County, Missouri, at the Oronogo-Duenweg Mining Belt National Priorities List (NPL) Superfund Site to clean up lead-contaminated, priority residential properties. 

The properties addressed through this removal action at the site are located within the Tri-State Mining District, where more than a hundred years of mining, milling, and smelting lead and zinc ore caused widespread contamination. Detailed site information, including ARs, are available on EPA’s Site Profile page.

ARs are official site files that contain technical documents about EPA’s response actions. EPA developed this AR to provide a clear understanding of the site actions. To view, please visit the link above (see Site Documents & Data, Administrative Records, and “Removal AR for Oronogo-Duenweg Mining Belt OU02, 03 2025”). If you do not have internet access, you can view these documents online at a local library, such as:

Lead is the main contaminant of concern at this site. It is a toxic metal that is harmful if inhaled or ingested and can pose serious health risks, particularly to children under 7 years old, as well as pregnant women and nursing mothers. For information on how to protect your family from lead hazards, visit EPA's fact sheet. 

Annual Childhood Lead Testing: EPA encourages parents and caregivers to have children under 7 years old tested for elevated blood lead levels annually. The only way to know if your child has an elevated blood lead level is to have his or her blood tested; lead-poisoned children do not always look or act sick.

Talk to your pediatrician, general physician, Jasper County Health Department (105 Lincoln St., Carthage, MO 64836; 417-358-3111); or other health care professionals about testing your child and to arrange for blood lead screening.

Contact EPA: If you have questions about this Time-Critical Removal Action, please contact On-Scene Coordinator Griff Hoffman at hoffman.griffith@epa.gov or 816-838-1758; or Community Involvement Coordinator Tanya Young at young.tanya@epa.gov or 816-799-3251.
