From 1947 to 1967, TCE was used in vapor degreasers for
automotive manufacturing. The name of the facility has changed several
times, but is now known as Dura Automotive Manufacturing Plant (Dura).
Through various improper disposal methods, TCE has nw contaminated the
groundwater in and around Mancelona, MI. The contaminated plume stretches
from the Dura plant to the Schuss Mountain/Shanty Creek Resort area, covering
a distance of roughly six miles. The plume has also streched to a width
of 1.25 miles at the leading edge. The first investigation for groundwater
contamination was conducted by the U.S. Environmental Protection Agency
(EPA) in 1986. The TCE concentration was found to be 830 micrograms per
liter (ug/L) or more than 160 times the maximum contaminate level (MCL)
set by EPA at 5 ppb. (1ug/L equals 1 ppb)
