Whitesburg Mayor James Wiley Craft said residents were being patient Sunday as they remained under advisement not to bathe or drink the water.
The advisory issued Saturday to many Letcher County residents was the result of an apparent fuel spill in the North Fork of the Kentucky River. The county judge-executive said the spill smelled and looked like diesel fuel.
People served by Whitesburg's water supply, including residents of Cowan, Little Cowan, Dry Fork and Mayking, are under the advisory.
Water was being distributed over the weekend at the Cowan recycling center and Whitesburg City Hall. Craft said each resident was allowed six gallons of water per day. Businesses could also pick up water.
Craft said the State Division of Water was testing the water, but the cause of the spill had not been determined on Sunday.
"People in Whitesburg have always been patient," Craft said. "This is the third time we've had to shut this thing down, and they've been very gracious, very nice."
A diesel spill by Childers Oil shut down the city water system for several days in February 2009.
