This story is misleading at best. The reporter called me Friday, asking whether sodium permanganate, used to chemically oxidize TCE, could create hexavalent chromium. Permanganate is made from manganate and sodium, elements. Chromium is an element. TCE does not have chromium in it. You cannot turn lead into gold. The only way that hexavalent chromium could be "created" is if it were mobilized by the chemical reaction (if, for example, trivalent chromium becomes hexavalent chromium during the chemical reaction - the latter is more toxic and mobile than the former). This was explained to the reporter, but she apparently stuck to her story.

It is a balancing act. By cleaning up vast amounts of the hazardous chemical trichloroethylene, which can evaporate into the air around homes and schools near the site, it could create trace amounts of a known carcinogen, hexavalent chromium. State officials overseeing the project being carried out by a firm hired by Wyle say that cleanup method will not be used unless they can minimize any public health risk. In preliminary tests, they found that hexavalent chromium -- also called chromium VI -- was created in the groundwater but had not traveled offsite. ...
