GALVESTON, Texas A boil-water notice was issued Tuesday for all residents of Galveston Island after a water sample tested positive for E. coli bacteria.

The sample was taken during routine testing. Following TCEQ procedures, the area was re-sampled again on Monday. Of those three samples, one tested positive for indicator bacteria not E. coli. However, state law required Galveston officials to issue the boil-water notice after the second round of tests.

To have a test result come back positive for e coli is extremely rare, in fact talking to some of our staff who have been here many years (they ve) never seen a result come back positive for E. coli in Galveston. We re talking decades, said Alicia Cahill with the city of Galveston.

All residents of the island, including those in Jamaica Beach and Pelican Island, are required to boil all water for human and animal consumption or use bottled water until further notice.

Galveston officials will continue to test water samples over the next 24 hours and lift the boil-water order once all samples meet state and federal standards for potable drinking water.

A formal announcement will be made with the boil-water notice is lifted.

Officials test drinking water samples in Galveston from 32 different sites twice monthly. They said it s highly irregular for samples to fail, and even more rare for a sample to test positive for E. coli.
