The six Canandaigua Lake water purveyors (the City of Canandaigua, the Village of Newark, the Village of Palmyra, the Village of Rushville, the Town of Gorham, and Bristol Harbour) are working alongside the Geneva District Office of the Health Department and the New York State Department of Health to monitor the public drinking water for the presence of toxins associated with harmful algal blooms. Samples of the public drinking water are routinely collected and sent to a State approved laboratory on a regular basis during the harmful algal bloom season to determine if toxins are present.
How to interpret these results. Raw water is water drawn from the lake before any treatment is applied. Finished water is the water after all required treatment has been applied and before the first customer.
Results are reported in micrograms per liter (ug/L). ND stands for not detected.
*On 9/11/19 it was discovered that the sample point previously being used for finished water was before full treatment (after filtration but before full disinfection contact time) had been applied. The sampling location was relocated to after full treatment and samples were collected from raw, true finished, and 3 points in distribution to ensure no lapse in monitoring.
