FORESTVILLE, N.Y. -- A boil water advisory is in effect for part of Chautauqua County. The county Health Department says routine water tests this week found potentially harmful bacteria in the water in the Village of Forestville.

Officials say residents should boil all water for one minute, and to cool it before using, or to use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice.

County health officials will continue to test the water through the holiday.
