FORESTVILLE – Routine samples collected from the village water system this week showed potentially harmful bacteria, and as a precaution the Chautauqua County Health Department has asked all village water customers to boil all water for drinking and cooking.

Bring all water to a boil, let it boil for one minute, and let it cool before using, or use bottled water certified for sale by the state Department of Health, county health officials advised. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice.

One potentially harmful bacteria was found – “a lot of it” – Mayor Beth Bowker told The Buffalo News. “We just found some bad elements and think it was an anomaly ... so we’re erring on the side of caution.”

Bowker declined to name the bacteria. She said county health workers will come in on Thanksgiving to analyze the samples taken today.

Water testing was conducted Tuesday and today, and at this point health officials aren’t sure if a system-wide contamination exists or if the contamination was isolated to a single water tap sample. Results from samples taken today are expected to be available Thursday afternoon.
