An undated photo from the 1980s, of two teenagers stepping on rocks and wooden planks on Coldwater Creek. The photo is from a scrapbook kept by Sandy Delcoure, who lived on Willow Creek in Florissant and donated the scrapbook to the Kay Drey Mallinckrodt Collection (State Historical Society of Missouri, Kay Drey Mallinckrodt Collection, 1943-2006).
Federal officials plan to post warning signs along a contaminated suburban St. Louis creek where generations of children were exposed to radioactive material.
Coldwater Creek , which winds between homes and parks in St. Louis County for 14 miles before meeting the Missouri River, is plagued with nuclear waste left over from World War II. For decades, families had no idea the danger it posed to the children who played along its banks and swam in its waters.
More than six years ago, a federal study found residents who live near the creek or regularly came in contact with its waters faced a higher risk of certain cancers.
