PROVIDENCE, R.I. (AP) — Several local elected officials are criticizing the Kent County Water Authority over how long it took to notify the public about potentially contaminated drinking water.

A boil-water advisory that will last at least three days is affecting about 25,000 residential and business customers.

Test results from a storage tank in West Warwick were positive Sunday for the presence of E. coli, a form of bacteria from human and animal waste.

The Providence Journal reports that mayors and city managers in some communities were surprised, if not dismayed, at receiving no direct notice at all.

Warwick Mayor Scott Avedisian said he is not happy with the way it was handled, and Gov. Lincoln Chafee said there's always room for improvement.

Timothy Brown, the authority's general manager, said notification was well within the required 24-hour period.
