Florissant, MO  (KTRS)  Efforts continue to gather information on potential health risks linked to Coldwater Creek in north county.

The Agency for Toxic Substances and Disease Registry held a second open house on Monday at the Jamestown Bluff Branch of the St. Louis County Public Library in Florissant, where residents had the opportunity to meet with scientists and ask questions. Barbara Gaston has lived in the area for the last thirty years. “It’s taken these folks forty years. They know it’s there. Why are we talking about this when we need to talk about cleaning it up.”

Diana Runge says she survived stage four bladder cancer and there’s no history of that type of cancer in her family. Now she’s concerned about her children’s health. “My sons grew up in the parks, playing in the parks, playing at my grandfather’s farm. I was raised here and my one son has M.S.”

Spencer Williams a toxicoligist and regional director for the agency, explains where they are in this process, which could take as long as two years for a final evaluation. “We’ve gathered data and our group back at headquarters in Atlanta are examining that data and we’re starting to build our unstanding of what people may have been exposed to in the past and the present and whether that might be an issue in the future.”

Last year the U.S. Army Corps of Engineers confirmed finding radioactive contamination near north county homes. Another open house is planned for next month.
