Sources of Perchlorethylene

Sources of Perchlorethylene

Sources of Perchlorethylene

(OP)
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.

RE: Sources of Perchlorethylene

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.
