Warning about tap water lifted

A state-mandated warning urging Downey residents to boil their tap water has ended, four days after officials announced that coliform bacteria had been detected in the water supply.

The order had been lifted for most of the city Sunday, but a small area in southeast Downey wasn’t cleared until late Monday evening, said Stefan Cajina of the state Department of Public Health.

The source of the bacteria has not been determined, and city, county and state health officials are studying the test results that led to the state’s order to see if the findings were erroneous, Cajina said. The order was taken as a precautionary measure, said Downey Mayor Pro Tem Mario Guerra.
