"A dangerous chemical used in dry cleaning is being phased out in California, but state regulators say we may still have to live with a toxic legacy for years to come."
"In this Assignment 7 report we take a closer look at the problem leaching into soil and drinking water around the state. At Crystal Cleaning Center in San Mateo, owner Lynnette Waterson uses a chemical called perchloroethylene, or PERC, to clean the toughest stains.
'It is the favorite solvent because of how well it cleans,' said Watterson.
Watterson owns what is likely the last PERC washing machine sold in California. She says if cleaners handle PERC correctly, it is safe. But this method of dry cleaning is on the way out. "
