‘Blue-green algae (has been) detected in very small quantities upstream from the Decew water treatment plant.’

Niagara, Ontario – Niagara Region is taking steps to address the presence of blue-green algae detected in very small quantities upstream from the water treatment plant intake at Decew Water Treatment Plant. Although the algae itself is harmless, it has the potential to produce toxins that are harmful at high concentrations.
While no toxins have been detected at this time, testing for toxins in these algae will continue daily. Tests conducted have shown that there is no toxin in the water at the treatment plant, nor upstream from it. Therefore, there is no risk to the public’s health.
The Region’s Public Works and Public Health departments are working with the Ministry of Environment and Climate Change to monitor and prevent any potential future risk to the public.
Water treatment processes have been adjusted to remove algae that might enter the water distribution system. Water is being tested daily. The Decew Water Treatment Plant supplies drinking water to St. Catharines and areas of Thorold, Lincoln, and Niagara-on-the-Lake.
Blue-green algae occurs naturally during periods of prolonged hot weather in fresh water lakes, ponds, rivers and streams in summer and early fall.
Niagara Region will continue to monitor the situation and should any changes occur will notify the public accordingly.
