Posted by Olog-hai on Sat Jan 27 20:58:47 2007, in response to Re: California bans *perchloroethylene*—dry-cleaning businesses severely hurt, posted by orange blossom special on Thu Jan 25 23:58:02 2007. Ultimately, at least 550 gallons of TCE soaked into the ground, penetrating as deeply as 40 feet and spreading outward for nearly 40 acres. Experts think the pollution continues to expand an acre a year . . . (TCE) sinks relentlessly through the groundEh? Where do they get this noise from, "penetrating"? 550 gallons is ten drums. Perchloroethylene evaporates and is not miscible with water (it's a non-polar compound and would emulsify, rather than dissolve, with water in small amounts). The Environmental Protection Agency has determined that even five parts of TCE per billion gallons of water poses an unacceptable health risk -- an amount roughly equivalent to five drops of water in an Olympic-sized swimming pool Have they? I don't see that on the EPA's own fact page; ain't that funny. The only reference to "five PPBG of water" of contaminants has to do with the standards of the Arizona Department of Health Services, regarding well water (and all well water ought to be tested before being consumed as drinking water, no matter where you're living) . . . |
