Algae are essential to life on earth. They are an important food and energy source and can capture carbon dioxide. However, excess algae and cyanobacteria in aquatic environments are undesirable and can wreak havoc on ecosystems, recreational activities, economies, and public drinking water systems.
Algae have long been known to produce objectionable taste and odor compounds in surface waters and drinking water. Many water treatment plants are also challenged by filter clogging diatoms. Yet, more recently, we’ve become aware of the risk that harmful algal blooms, including photosynthetic cyanobacteria, may pose to human and animal health through the production of algal toxins.
Prevention of HABs may be the most effective way to avoid the production of algal toxins and taste and odor compounds. However, HAB management requires a holistic One Water approach to water supply management. Key management strategies include:
Understanding and predicting the impacts of climate change is also an important element of a One Water control strategy. Our One Water approach brings together subject matter experts across the water cycle to collaboratively find HAB solutions to sustain and utilize water resources.
Our modeling group has been at the forefront of developing and applying mathematical models to address the impacts of pollutant discharges on water quality and ecosystem health.
We provide two open-source models that are available to the modeling community.
