FREDONIA – The Chautauqua County Health Department advises residents to boil tap water and limit their water use while repairs are being made to the village water plant’s treatment system.

The orders are expected to remain in effect until at least Saturday.

Health officials issued a boil water advisory Wednesday morning after a failure in a chemical feed pump at the plant caused the water to become cloudy.

Water plant operators then switched sources to keep additional substandard water from entering the system, drawing from the village’s storage tanks and opening a connection to the City of Dunkirk’s supply.

The volume of water from those sources is limited, however, and residents are urged to cut their water usage in half by limiting showers, shutting off running toilets and avoiding the use of washing machines and dishwashers.

All Fredonia Central School activities Wednesday night were canceled to save water.
