On the morning of one of the hottest days of the year, the City of San Fernando celebrated returning to its water wells after two years of importing water from the Metropolitan Water District of Southern California (MWD). The city purchased water from MWD after nearing unsafe levels of nitrates in the city’s wells, which required them to be shut down. … After years of water treatment implementation in some contaminated wells, the City of San Fernando officially turned off the connection to MWD on March 8, marking a return to using its well water system.
