New monitoring devices for algae will be placed in three different bodies of water on Prince Edward Island this summer as part of a trial project to enhance the understanding of blue-green algae blooms. Kyle Knysh, a surface water biologist in the province, mentioned that blue-green algae, also known as cyanobacteria, has been identified in various locations on the island in recent times.
The three trackers will be situated at MacLures Dam in Murray River, Parsons Creek in Stanhope, and Point Deroche Pond near Blooming Point. The main objective of these trackers is to analyze the frequency and duration of blooming conditions. Additionally, they can serve as tools to monitor potential high levels of the bacteria for public health purposes.
According to the environmental health division of P.E.I., toxins from blue-green algae can have adverse effects on both human and animal health. Exposure can occur through contact with or ingestion of contaminated water. Potential health impacts include mild issues like skin and eye irritation, stomach problems, and in rare cases, more severe illnesses. The public is advised to steer clear of water with visible blue-green algae blooms, adhere to local health advisories, and keep children and pets away from affected areas.
Knysh highlighted environmental concerns associated with blue-green algae blooms, stating that large blooms can generate abundant organic matter that sinks to the bottom of water bodies, further reducing oxygen levels in certain systems. Climate change, warmer temperatures, nutrient availability, and water column stability are factors contributing to the proliferation of blue-green algae. These factors can interact in various ways to create favorable conditions for algae growth.
In recent years, blue-green algae has been detected in more water bodies on P.E.I. Knysh mentioned that at Parson’s Creek, high levels of blue-green algae persisted until the water froze over. The new algal tracker to be deployed in that location is hoped to provide insights into the reasons for the elevated bacteria levels compared to other nearby water bodies. Visible indicators of blue-green algae include water that appears scummy, resembling pea soup or spilled green paint.
Individuals suspecting blooming conditions can contact P.E.I.’s Land and Environment Department for investigation.
