The Jurupa Community Services District has lifted a drinking water warning after tests cleared the water supply for any remaining presence of E. Coli in Riverside County. On Wednesday, a water sample “detected E. coli at a water source before disinfection, not in the distribution system,” district officials said. “The water source was removed from the system.” On Sept. 27, a Drinking Water Warning was issued for parts of Jurupa Valley. Those in affected areas were encouraged to boil water before consuming. There were also stations where water bottles were being handed out for free. … Crews worked to disinfect and flush out the water systems. After water quality test samples taken on Thursday and Friday came back negative for contaminants, the Drinking Water Warning was lifted on Saturday night.
