California Water Service Cancels Do-Not-Drink Advisory in Palos Verdes Estates

TORRANCE, Calif.— California Water Service (Cal Water) has canceled its do-not-drink advisory for the 200 customers in a portion of its Palos Verdes water system, and it is safe for them to resume normal water use. The company had issued the precautionary advisory after a small storage tank serving a portion of the system was found to be compromised on Monday.

Residents of this area had been advised to not drink the water and to use bottled water for drinking and cooking due to a security breach at a tank that could have affected water quality. Cal Water has introduced an alternate source of high-quality water into the system and conducted field measurements, and all results to date indicate no evidence that water quality was compromised.

"Protecting our customers' health and safety is our top priority," said Dan Armendariz, District Manager. "We apologize for the inconvenience and are conducting a full investigation with the State's Division of Drinking Water and local law enforcement to ensure the water supply remains safe for our customers."
