Blue-green algal blooms close reservoirs and threaten water supplies because they’re poisonous – and even deadly – to animals, humans and the environment. CSU Chemical and Biological Engineering Professor Brad Reisfeld is leading a U.S. Environmental Protection Agency grant to develop a low-cost, floating early warning system that could help stem illness and environmental threats from algal blooms. The $25,000 People, Prosperity and the Planet (P3) student design competition grant to CSU also includes Professors Steve Simske in Systems Engineering, and Ed Hall in the Department of Ecosystem Science and Sustainability, Warner College of Natural Resources.
