EPA's Webinar: Planning for and Responding to Cvanotoxins in
Recreational Waters
On June 20, the Office of Science and Technology hosted a webinar focusing on available tool
and approaches for assessing the risks and managing cyanobacteria and their toxins in
recreational waters. The webinar also included presentations on HABs monitoring and surveillance
efforts in New York State and a presentation on the lessons learned from the 2018 Microcystin
dogs poisoning in Stuart, Florida. Presentations and recording of the webinar are posted here.
10th US HABs Symposium
November 3-8, 2019 at Orange Beach, Alabama
The 10th US Harmful Algal Bloom Symposium website ("http://ushabs.com/') was recently updated
with the schedule that includes many exciting events, including five workshops, three plenaries,
four events targeted for early career scientists, three special sessions, many contributed sessions,
a stakeholder meeting, a town hall meeting, and several fun social events.
If you have not yet registered, please do so before the early bird deadline ("August 31, 2019") to
save some money. Abstract submissions and workshop registrations will be considered up to
August 31st or October 15th, respectively.
Travel grants for graduate students, postdocs, and managers are available to attend this meeting
(special thanks to the National Oceanic and Atmospheric Administration National Centers for
Coastal Ocean Science (NOAA/NCCOS). The deadline to apply is July 31, 2019. Learn more
about this opportunity at http://ushabs.com/lib/travel awards.pdf
The Early Career Workshop will be held on Sunday, 3 November 2019, from 4:00pm to 5:45pm.
All students, postdocs and early career scientists are encouraged to attend. The agenda is a
mixture of information exchange amongst participants through elevator speeches and discussions
with a panel of HABs scientists from diverse backgrounds. Please contact Molly Miller
("mmmiller@disl.org') if you have questions about this event.
Hotel Reservations: Don't forget to book your room at the beautiful Perdido Beach Resort as our

The Cyanobacteria Assessment Network mobile application ("CvAN app1) is free and
available for download on Google Play™. It is designed for use on Android™ devices
and is compatible with versions 4.2-8.0 (API levels 18-26). It is currently being
developed as a web-based app, which will be compatible with most devices.
