In May 2009, a BASF Plant in Hannibal, Missouri, United States, accidentally discharged chromium into the Mississippi River. The local Department of Natural Resources performed tests in December 2009 showing the chromium levels did not exceed regulatory safety limits. BASF worked with the Missouri Department of Natural Resources (MoDNR) to resolve questions regarding the elevated level of hexavalent chromium that was detected in the effluent from one of its permitted outfalls into the Mississippi River. The state department of health reviewed the test results and determined that the amounts found were well below recommended public health screening levels.Henley, Danny (12 February 2010).
