WECHU warns of blue-green algae bloom

The Windsor-Essex County Health Unit (WECHU) is issuing a precautionary notice to residents based on initial laboratory results of a blue-green algae bloom in the region. WECHU reports the bloom is in the Ruscom River in the area of Trepanier Road and Lakeshore Road 129, in between St. Joachim and Comber. While initial chemical analysis does not show the presence of Microcystin related toxins within the samples collected, toxicity may increase due to the algae identified in the bloom. The health unit said residents on the municipal drinking water system can continue to drink the water. Routine water testing is done by the municipal water treatment plant and at this time there are no concerns. 'As a reminder, wind and water conditions may move the blue-green algae bloom towards other areas. Residents and visitors are urged to take a cautious approach and protect themselves, their children, and their pets from potential health risks,' says Dr. Aloosh, Medical Officer of Health. Residents that use wells or cisterns that draw water directly from the Ruscom River in the area of Trepanier Road and Lakeshore Road 129 (such as private cottages with wells) are advised not to drink the water unless they are routinely testing for microcystins using a licensed lab and results show levels less than 1.5 ppb. What is blue-green algae? Blue-green algae (cyanobacteria) are microscopic organisms that occur naturally in freshwater lakes, ponds, rivers and streams in the late summer and early fall. They are usually present in low numbers but can rapidly increase in warm, shallow, undisturbed surface water that gets a lot of sun. When this happens, they can form blooms that discolour the water or produce floating scum on the surface of the water. These blooms can make the water appear bluish-green, can form solid looking clumps, and may contain toxins, called microcystins, that can be dangerous to human and animal health. Contact with microcystins can produce negative health effects in humans such as skin and eye irritations and if ingested can lead to headaches, fever, diarrhea, abdominal pain, nausea, and vomiting.

Heat warning continues with WECHU offering guidance

As the extreme heat continues to grip the region, Windsor's top doctor is urging residents to take care of themselves. Windsor-Essex County Health Unit (WECHU) Medical Officer of Health, Dr. Mehdi Aloosh said it's important to drink water and keep hydrated and stay in shaded areas. 'If they don't have air conditioning in their house, people can go into malls, community centres, libraries, to keep themselves safe from the hot weather,' said Dr. Aloosh. He said to watch for signs of heat stroke in yourself and others. 'Thirst, lightheadedness, it starts with cramping, and then some of the fogginess in thinking,' said Dr. Aloosh. Dr. Aloosh said it's important to regularly apply sunscreen when outside. 'The generally recommendation is that when you are out, and even if you are not under the sun, you need to use that even if it's a cloudy day,' he said. Environment Canada has issued a heat warning. The weather service said showers and thunderstorms are expected to move through on Monday, ending the extreme heat and humidity by Monday evening. - Written by Dustin Coffman and Meagan Delaurier/AM800 News.
