California Utility Takes Proactive Approach to THM Control in 12-MG Underground Tank

San Jose, CA

San Jose Water carries out a thorough and sophisticated water quality monitoring program to protect public health. In February 2014, these programs alerted management to a significant new threat to drinking water quality: disinfection byproducts (DBPs). While their water system remained in compliance, managers at San Jose Water wanted to eliminate the risk of a future operational exceedance in the summer of 2014 – when THM levels were expected to be highest.
