Coldwater Creek overview
based on 1997 Riverfront Times reporting by C.D. Stelzer
COLDWATER CREEK, which is next to the Airport Site, flows through a large section of North St. Louis County and has acted as a convenient vehicle to transport the toxic materials. So far, radioactive contaminants are known to have hitched a ride downstream more than seven miles, according to the DOE. And the migration is continuing. Tests conducted in late 1994 show stormwater runoff at the location still exceeding acceptable radiation levels set by the agency. Drinking-water intakes for the city of St. Louis are located several miles downstream from the site, on the Mississippi River at Chain of Rocks. The radioactive migration by way of groundwater has also been confirmed but is less well understood.
For years, the DOE claimed the waste presented no danger. But the scientific community, which has been moving much more slowly than the waste, has finally concluded that no safe level of radiation exposure exists. By the time this decision was made several years ago, it was also widely accepted that one direct effect of long-term exposure to low-level radiation is cancer.
The $8.3 million cleanup along Coldwater Creek is the first stage of the long-anticipated project. The initial phase involves removing at least 6,000 cubic yards of the contaminated soil to a licensed repository for low-level radioactive waste, located in Utah. The amount is only a small fraction of the contaminated materials that may ultimately be excavated and shipped from the site. The approximate completion date: 2004.
[Obviously, that deadline has long passed.]
