Denver (AP) A wildlife refuge at the Rocky Mountain Arsenal will reopen to the public on June 14 after a cleanup at a spot where a chemical weapon was detected last year.
Health and Environment Officials said Monday that excavation work has been completed and groundwater monitoring wells have been installed in a part of the arsenal used to dispose chemical agents. That area will remain closed to the public.
The part of the arsenal that is now a wildlife refuge was closed last October after A World War I-era chemical weapon called Lewisite was detected.
The Army manufactured chemical weapons at the 27-square-mile arsenal. Shell oil produced pesticides and other chemicals there until 1982. The arsenal became a superfund site in 1987, and congress decided to turn it into a national wildlife refuge in the 1990s.
