As analytical methods improve, it is being reported that researchers are finding low-levels of perchlorate nearly everywhere, which suggests it is part of the natural background.

Just because you can find two parts per quadrillion of dimethyl chickenwire in something doesn't make it mean anything.

The statement that perchlorate is being found nearly everywhere paraphrases a statement by Rebecca Renner of the American Chemical Society found at following link: Societyhttp://216.109.117.135/search/cache?p=atmospheric+processes+may+explain+perchlorate&tab=Web&ei=UTF-8&u=pubs.acs.org/subscribe/journals/esthag-a/39/i06/pdf/031505news.pdf&w=atmospheric+processes+may+explain+perchlorate&d=0198B80870&icp=1&.intl=us.

The point that infinitesimal parts of perchlorate are found in drinking water when it is generated in nature at that same level is problematic to say the least to continued perchlorate regulation and cleanups costing multiple billions of dollars. WL
