Rising global temperatures are causing harmful algal blooms in the Great Lakes which can lead to the emergence of three toxins in the water, according to the past president of the International Ozone Association. Saad Jasim, an adjunct professor at the University of Windsor, is preparing for a new research project to prevent these toxins from entering the drinking water supply.
Quebec City is enforcing tighter water restrictions
"The challenge is not necessarily our water sources, but rather our ability to produce and deliver it, " said Marie-Josée Asselin, vice-president of the city's executive committee. "When everyone consumes water at the same time, this is when we put ourselves at risk in terms of distribution and production." Quebec City found that watering lawns has put the most pressure on its drinking water tanks in dry weather.
Water quality advisory issued for Nelson
A water quality advisory has been issued for Nelson during spring run-off conditions. The City of Nelson said in a statement Wednesday that increased levels of turbidity or suspended matter have been found in the drinking water supply. The water can still be consumed, but Interior Health recommends residents with compromised immune systems take precautions when drinking it, washing fruits and vegetables or brushing their teeth.
Water quality advisory issued for Horse Lake
The Cariboo Regional District has issued a water quality advisory, to the Horse Lake water users as a result of levels of manganese (Mn) in its drinking water supply. The quality of the drinking water has not changed, but the move is due to changed Canadian guidelines for drinking water. Health Canada established a new maximum acceptable concentration for manganese in drinking water of 0.12 mg/L. Historical water test results show that the wells in Horse lake have produced between 0.14 to 0.29 mg/L of manganese. These manganese levels vary per well and what time of year the tests were taken.
Metro Vancouver's drinking water pH and alkalinity to increase this spring
Through the use of “natural materials,” the alkalinity of Metro Vancouver’s water will be doubled to about 20 mg/L, expressed as calcium carbonate. The region’s water pH will increase from the existing target of 7.7 to a new target range of 8.3 to 8.5. Health Canada’s guidelines for safe drinking water quality stipulates a pH range from 7.0 to 10.5. During the water treatment process, the regional district already adjusts the pH as the untreated source water is naturally slightly acidic.
