- More than 80% of U.S. dry cleaners rely on the solvent PCE
- (perchloroethylene), a chemical that is listed under the Clean
- Air Act as a hazardous air pollutant. Perc, as it is commonly
- known, can cause dizziness and headaches in workers, and some
- controversial studies link it to miscarriage and cancer. Perc
- is also fingered for contaminating underground water systems as
- well as apartments and restaurants adjacent to dry-cleaning
- establishments.
-
- About 40% to 45% of the estimated 500 million pounds of
- perc produced annually is used by cleaners. In an effort to
- reduce exposure to perc, the Environmental Protection Agency,
- in collaboration with trade groups, has launched a four-week
- test of a new cleaning method that eschews all chemical solvent
- and depends instead on biodegradable soaps along with heat,
- steam and pressing. The experiment uses clothing volunteered by
- government employees in Washington and New York City. First up
- was EPA chief William Reilly, who turned over his regulation
- blue suit.
