Many types of algae can cause HABs in freshwater ecosystems. The most frequent and severe blooms typically are caused by cyanobacteria, the only freshwater “algae” with the potential for production of toxins that can adversely affect human health. USGS Texas Water Science Center (TXWSC) scientists studying HAB issues in water bodies throughout the United States, using a combination of traditional methods and emerging technologies. Visit the links below for more information on our data and science.
Cyanobacterial harmful algal blooms (CyanoHAB) pose a threat to human and aquatic ecosystem health and cause economic damage. Despite advances in scientific understanding of cyanobacteria and associated compounds, many unanswered questions remain about occurrence, environmental triggers for toxicity, and the ability to predict the timing, duration, and toxicity of CyanoHABs. By providing practical applications of cutting edge CyanoHAB research, USGS studies have advanced scientific understanding, enabling the development of approaches to help protect ecological and human health.
