Some Letcher County residents have been advised not to drink or bathe in their water because of a fuel spill in the North Fork of the Kentucky River, Letcher County Judge-Executive Jim Ward said Saturday evening.
State Division of Water and county officials were testing water between Mayking and Whitesburg, Ward said, and hadn't determined what was causing problems.
He said the spill smelled and looked like diesel fuel.
Any Letcher County residents on the city of Whitesburg's water supply, including residents of Cowan, Little Cowan, Dry Fork and Mayking, are under the advisory.
Never miss a local story.
Officials were distributing bottled water at the Cowan recycling center and at Whitesburg City Hall.
Any county customers outside those areas are served by a tie-in with the Knott County water system, a move that happened after a diesel spill by local company Childers Oil shut down the city water system for several days on the same weekend in February 2009.
