After a five-month intensive investigation of toxic air
pollution in the Rubidoux area of Western Riverside County, AQMD has
identified TXI Riverside Cement as the source of elevated levels of the
cancer-causing chemical hexavalent chromium in the Rubidoux area. As a
result, AQMD will take aggressive action to reduce the hexavalent
chromium emissions from Riverside Cement and lower the risk levels in the
community around the facility.
