Public health officials issue water warning after E. Coli discovered in Jurupa Valley water source

Public health officials have issued a drinking water warning to Jurupa Valley residents after a positive case of E. Coli was discovered at a local water source. 
The warning remained in effect through the weekend but was lifted on Monday afternoon after tests found that there were no traces in the water.
The positive test sample of the fecal indicator was found on Wednesday, according to the Jurupa Community Services District. Authorities say that the sample was found before disinfection took place and it was subsequently removed from the water system.

More than 1,000 cases of bottled water were distributed on Friday afternoon. More water is available for pickup over the weekend at four locations, including:
