Reduce public health issues

Cyanotoxins: Many species of cyanobacteria (blue-green algae) produce very potent intra-cellular toxins. Not all blue-green algae possess toxins, but bloom-forming species are typically capable of producing neurotoxins, hepatotoxins, and/or dermatoxins. When these toxic blooms dominate the algal community, the rest of the lake biota suffers and biodiversity diminishes. Unfortunately, lake biota can also include humans and pets, and reported instances of severe illness and death from both groups have been attributed to accidental consumption of toxic blue-green algae. Although animal illness and deaths have been reported worldwide since the late 1800s, it has only been since around the late 1990s that the drinking water industry and the general public have begun to really appreciate the importance of cyanotoxins to public health. Controlling toxic blue-green algae, therefore, and not necessarily the edible non-blue-green algae, is really the critical lake management issue.

Coliform bacteria: Coliform bacteria (e.g., Escherichia coli) dwell in the gastrointestinal tract of warm blooded animals, and get into surface waters through their excretions. Excessive fecal coliform concentrations often close recreational waters during summer months. Limited coliform data collected at several recreational lakes where SolarBees are installed for blue-green algae control indicate some reductions when compared to prior years. SolarBee circulation greatly enhances the volume of water exposed to surface irradiation from the sun. Coliform bacteria are susceptible ultraviolet radiation, so reported decreases in coliform counts are reasonable. Although a formal, systematic study has not yet been completed, reports from lakes with SolarBees have been sufficiently consistent that some reductions in coliform counts should be a reasonably anticipated benefit from SolarBee circulation.
