MARICOPA, AZ — A precautionary boil water advisory for Global Water Resources customers in the city of Maricopa has been lifted after follow-up testing found no E. coli in the water samples.
Global Water Resources announced the cancellation Thursday, October 8, at 2 p.m., saying repeat test results came back negative for E. coli.
The advisory was issued Wednesday after two preliminary water tests indicated the tap water could be contaminated with the bacteria.
Global Water collected additional water samples on October 7 and sent them to a third-party laboratory for testing. Those repeat tests did not detect E. coli.
Is Maricopa tap water safe to use?
Global Water says customers no longer need to boil tap water before drinking it, cooking, making ice, brushing their teeth or washing dishes.
The utility also says customers do not need to take any special precautions with household or business water filtration systems, although they should continue following manufacturers' instructions.
According to Global Water, Arizona Department of Environmental Quality regulations do not require customers or the utility to take any further action following the advisory's cancellation.
