Hexavalent chromium is rather famous as toxins go. Commonly inhaled by unsafe arc-welding, the chemical was made infamous by the investigation of Erin Brockovich, who found the substance had infiltrated the groundwater of Hinkley, Calif. The European Union, and Canada both passed tougher regulations for its control in recent years to match those of the U.S.; the United States is currently updating the chemical's entry in its Integrated Risk Information System (IRIS).
The comment period was extended at the behest of the American Chemistry Council (ACC). The draft assessment was prepared by the National Center for Environmental Assessment (NCEA) within the EPA Office of Research and Development (ORD). After public review and comment, an EPA contractor will convene an expert panel for independent external peer review of this draft assessment. Public comments submitted during the public comment period will be provided to the external peer reviewers before the panel meeting and considered by the EPA in the disposition of public comments. Public comments received after the public comment period closes will not be submitted to the external peer reviewers and will only be considered by the EPA if time permits.
Remediation of water and soil contaminated by hexavalent chromium was the topic of a feature article in PE's August 2007 edition.
