March 31, 2023

The U.S. Army Corps of Engineers (USACE), St. Louis District, Formerly Utilized Sites Remedial Action Program (FUSRAP) continues to investigate Coldwater Creek (CWC), completing approximately 13 miles of the creek and collecting over 34,000 samples as of March 16. Currently, USACE is performing investigative sampling from Highway 367 to the Missouri River.

Each 1-mile section of the creek equals to 30 to 150 acres of the 10-year floodplain adjacent to the creek that needs investigation and sampling. The investigation includes 14.2 miles of the creek corridor (banks and sediments) and adjacent properties within the 10-year floodplain. Sampling is conducted at various depths between 0 to 10 feet below ground surface, depending on the target sample location, and may be deeper in order to reach native soil. 

Low-level radiological contamination has been found in isolated areas along the creekbanks and within the 10-year floodplain. The contamination found is typically below ground surface and doesn’t pose an immediate risk to the public in its current configuration. The FUSRAP team performs follow-up investigation on areas of CWC where contamination was found as well as delineation for remedial-design purposes.

After the initial investigation is completed, USACE sends preliminary status letters to property owner, informing the property owner of the status of the property.
