Blue-green Algae Toxin Detected in Village of Rushville Water Above Health Advisory Level
Bottled water available free at the Rushville and Middlesex Fire Depts.; schools will be open with provided water

The New York State Department of Health recommends that all consumers served by the Village of Rushville’s Public Water Supply, including customers in the Middlesex Water District, use an alternate source of water for drinking, cooking, making infant formula, making ice, and preparing food and beverages until further notice. The water is acceptable for other household uses, such as bathing, washing hands, washing dishes, flushing toilets, and cleaning. Boiling water and in-home treatment will not remove the blue-green algae or their toxins.

Samples collected by the Village of Rushville Public Water Supply show a blue-green algae toxin called Microcystin was detected in the drinking water delivered to consumers. Microcystin entered the supply due to blue-green algae blooms occurring in Canandaigua Lake, which is the source water for the Village of Rushville’s Public Water Supply. 

Sampling collected on Tuesday, Oct. 9 returned results of 0.66 micrograms per liter of Microcystin in finished water. This level is higher than the U.S. Environmental Protection Agency’s 10-day Health Advisory level of 0.3 micrograms per liter of Microcystins for bottle fed infants and children under 6 years old. For individuals not included in that group, the EPA’s health advisory level is 1.6 microgams per liter. However, out of an abundance of caution, the state is recommending all consumers do not consume water at this time. Confirmatory samples are being collected and tested at the Wadsworth Center, the NYSDOH’s public health laboratory.

The Village of Rushville’s Public Water Supply is working with the N.Y.S. Department of Health and Ontario and Yates counties to provide bottled water for residents while the advisory remains in effect. We will notify consumers immediately when the Health Advisory is discontinued and the water is suitable for all household uses.

Rushville Mayor John Sawers says free bottled water for drinking will be available at the Rushville and Middlesex Fire Departments. Supply is limited to five gallons per family. Schools will be open, says Sawers. Bulk water is being provided to the schools served by the Rushville water system, mainly for the cafeteria to continue to operate; and bottled water will be provided for students, faculty, and staff.
