Harmful Algal Bloom
Large blue-green algae (BGA) blooms create a number of public safety issues. All BGA can cause skin rashes and some produce specific toxins that can affect internal organs and nervous systems of both humans and animals. Response to this issue during the 2010-2011 timeframe includes, for instance, the state of Kansas developing a BGA policy that adopted the World Health Organization (WHO) “Guidelines for Safe Recreational Water Environments.” Those guidelines use cell counts of toxin producing BGA to recommend specific actions, from issuing Health Advisories and Warnings, to lake closures.

- Under ANSRP, the work unit, Harmful Algal Bloom indicator estimation in small inland waterbodies: Remote sensing-based software tools to assist with USACE water quality monitoring (FY19-21), was developed to produce and expand satellite image-based tools for estimating water quality indicators of HABs in support of USACE water quality monitoring needs. The tools accommodate a broad range of skills and needs across USACE and include the following:

Harmful algal blooms occur in fresh water when aquatic microorganisms, called cyanobacteria, grow rapidly and sometimes release toxins that are dangerous to humans and aquatic life. Such events can compromise drinking water reservoirs, disrupt recreation, shut down fisheries, and kill fish, birds and other aquatic species. Scientists agree that these events are happening more often and in more diverse locations and through 2018 WRDA authority, ERDC has implemented a five-year research program to deliver scalable technologies to detect, prevent and manage harmful algal blooms. We are joined on this podcast by EL's Dr. Jen Seiter-Moser, technical director overseeing Civil Works Environmental Engineering and Sciences, and Molly Reif, Geospatial Data Analysis team lead, as we delve into why ERDC is studying this issue, the scope of our harmful algal bloom research, a specific project that uses remote sensing to detect the presence of blooms, and ways ERDC is leveraging cross-disciplinary expertise to discover solutions for harmful algal blooms.
