Harmful algal blooms, or HABs, occur when there is too much growth of algae in water. Some (cyanobacteria, also referred to as blue-green algae) produce toxins that are dangerous for animal and human health, as well as a financial impact for drinking water treatment plants. (Reference: https://www.epa.gov/nutrientpollution/harmful-algal-blooms)
These blooms are a particular issue in the Great Lakes region of the United States in the late summer months. Several species of cyanobacteria can produce a variety of toxins including hepatotoxins and neurotoxins. In addition, some species can produce so-called taste and odor compounds that, though not toxic, can lead to drinking water customer complaints, and thus represent a considerable treatment objective.
Environmental water researchers use the HORIBA Aqualog to monitor fluorescence signatures of organic matter derived from HABs which can be an indicator of upcoming blooms. Click here to go to the Aqualog - Environmental Water Research Analyzer product page.
