A study released by the Environmental Working Group (EWG), found that a mix of pollutants in California drinking water could cause an estimated 15,500 additional cases of cancer over the course of a lifetime. While concerns about water quality and safety continue to grow, it is important to note that a number of California utilities are already implementing real-time, online monitoring to determine the presence of water-borne contaminants of concern and ensure drinking water safety at all times. AMS is helping these utilities to not only identify THM and trace metal contaminant threats, but also to diagnose critical treatment system performance once a solution has been put in place.
