The Effects of Septic Pollution on Biodiversity
by Paige Jessup, Climate Change Resiliency Intern The loss of biodiversity in freshwater and terrestrial ecosystems has been a growing issue for freshwater communities. Run-off from improperly installed or unmaintained septic systems are one of the ways that untreated wastewater gets into freshwater bodies. Things like cracks in the tank can also cause nutrients from the wastewater to leach into the soil, which can lead to highly undesirable changes in local ecosystem structure and ... Read More
Hidden Dangers: How Could your Septic System be Affecting Water Quality

If you live in an area that is connected to a municipal sewer system, the water that is ... Read More
History of Cyanobacteria (Blue-Green Algae) in Canadian Waters
by Paige Jessup, Climate Change Resiliency Intern Cyanobacteria, or “blue-green algae”, are one of the old living organisms on earth, evolving from a group of microbes approximately 2.7 billion years ago. Cyanobacteria are thought to be the cause of one of Earth's mass extinctions called “The Great Oxygenation Event” which took place between 2.4-2.1 billion years ago and wiped out almost all life on earth (Aiyer, 2022). Cyanobacteria survived this extinction and eventually went through a ... Read More
The Consequences of Cyanobacteria on Freshwater Ecosystems
by Paige Jessup, Climate Change Resiliency Intern Cyanobacteria, also known as blue-green algae, is one of the oldest living organisms on earth and are generally unicellular. These organisms are photosynthetic and require sunlight, water, and nutrients such as nitrogen and phosphorus to reproduce. Due to current land use practices along Canada's shorelines, humans are opening up these organisms to these perfect conditions they need to reproduce each year and also to reproduce earlier in the ...
