The U.S. Army Corps of Engineers' Formerly Utilized Sites Remedial Action Program (FUSRAP) is currently remediating properties adjacent to Coldwater Creek from upstream to downstream. In 1998, USACE removed contamination from Coldwater Creek to support the City of Florissant’s upgrade of the St. Denis Bridge over the creek. In 2005, contamination in CWC was removed as part of the cleanup at SLAPS.
