Summary:.Harmful Algal Blooms (HABs) are increasingly impacting aquatic systems, reducing provided ecological services and requiring expensive engineered solutions. HABs, particularly those dominated by cyanobacteria (cyanoHABs) are a public health, ecologic, and economic concern. Characteristically, cyanoHABs produce large amounts of biomass and have the potential for producing taste and odor compounds and potent cyanotoxins. Cyanotoxins are now under review for regulation on the Contaminant Candidate List 3. The primary objective of this project is to develop empirical relationships between algal community composition, toxicity, and cyanotoxin concentrations with temporally dense data. This information can be used by water quality managers to optimize responses to cyanobacterial blooms and their toxins. Lopez et al. noted the following in the Interagency Working Group on Harmful Algal Blooms, Hypoxia, and Human Health of the Joint Subcommittee on Ocean Science and Technology's report,

"An ideal monitoring system would allow for real-time, highly automated, accurate bloom detection that in the short run could provide early warning of impending toxic events and will lead to better predictive capability in the long run.”

This project will use currently available water quality monitoring technologies to collect high frequency data on algal population dynamics at the division level, whole-organism responses to cyanoHABs and their toxins, and abiotic parameters that influence bloom occurrence and cyanotoxin production. These data will form the basis of data driven predictive models to achieve the goal of a ``real-time, highly automated, accurate bloom detection'' system.

Presenter: Dr. H. Joel Allen U.S. Environmental Protection Agency

Joel Allen earned his Master and Ph.D. of Environmental Science degree from the University of North Texas and is employed by the U.S. Environmental Protection Agency, Office of Research and Development. Dr. Allen’s research interests lie in the application of technology to toxicological methodologies enabling continuous, on-line monitoring of water quality using biosentinels. While at the U.S. Environmental Protection Agency’s National Risk Management Research Laboratory, he has developed and evaluated on-line toxicity monitors as well as performed research on environmental endocrine disruption and nanoparticle toxicity. Dr. Allen worked with EPA regional partners in the design and implementation of the Upper Mississippi Water Quality Monitoring Network, an effort to digitally monitor water quality using technologically sophisticated approaches. Current research includes development of temporally dense data sets for assessing trends and impacts of source water quality on drinking water processes with particular emphasis on harmful algal blooms.
