Motorola, Inc., Siemens Corp. and GlaxoSmithKline will collectively pay a $500,000 civil penalty for system failures that led to the release of trichloroethylene (TCE) into the public drinking water system in Scottsdale, Ariz. A quantity of TCE exceeding contamination limits was released from the Miller Road Treatment Facility on two separate occasions, in October 2007 and January 2008. According to the Justice Department, the companies “failed to properly treat groundwater for TCE at the site and further failed to alert proper authorities about the release despite being under an agreement to do both.”
