Enhancing or restoring ecosystem services in oxygen stressed water bodies – exploring potential applications for a novel aeration device

Many bodies of water are facing a decline in concentrations of oxygen in the water. This is mainly because human activities have increased the amount of nutrients and organic matter entering these water bodies, which in turn fuels microbial activity that consumes available oxygen. When oxygen levels drop, the health of the ecosystem suffers, and the important services these environments provide can be lost or diminished.
Our research will test a new aeration technology developed by E M Fluids, Inc. This device is designed to add oxygen back into the water, potentially helping lakes and wetlands recover their natural balance. Specifically, we will study how aeration affects:
• The release of methane, a powerful greenhouse gas, from wetlands and lakes.
• The survival in surface water of faecal bacteria, which can pose health risks.
• The amount of algae and harmful cyanobacteria in lakes and reservoirs.
Through this work, we aim to find out whether E M Fluids’ new device can be a practical tool for restoring water quality, reducing greenhouse gas emissions, and protecting public health. The results will help identify new application opportunities for this technology to benefit aquatic environments.
