Sources of Perchlorethylene 1

[Egor]

I am currently working with another gentleman and we are investigating a landfill site that has perchlorethylene (perc) as a contaminate. We are trying to identify what may have been the sources of the perc. We are familiar with drycleaners as a source. We also understand that it was used as a degreaser in maintenance areas.

But, we are wondering if anyone has a listing of other sources that would processes or otherwise use perc.

Would appreciate any help or comments.

According to the EPA:
The largest use for perchloroethylene is in dry cleaning and textile
operations, accounting for an estimated 60 percent of all perchloro-
ethylene use in the US in 1991. It is also used in the production
of chlorofluorocarbons; in vapor degreasing and metal cleaning
operations; in aerosol formulations; as a carrier for rubber
coatings, solvent soaps, printing inks, adhesives, sealants,
polishes, lubricants, and silicones; and as a solvent in various
consumer products, such as typewriter correction fluid and shoe
polishes.
Hope this helps.
