Harmful Algal Blooms (HABs)

Cyanotoxins from harmful algal blooms (HABs) are occurring with increasing frequency in drinking water sources and negatively impacting drinking water treatment facilities throughout the US. These treatment facilities face a difficult task of not only removing the toxins but doing so in a safe and cost-effective way.

Harmful Algal Blooms (HABs) Websites

Wisconsin, Indiana, Oregon and Ohio each have algae websites that provide information, fact sheets, and resources for the public about possible high levels of blue-green algae and the potential health effects of Cyanobacteria.
