EPA's Recommended Recreational Ambient Water Quality
Criteria or Swimming Advisories for Cvanotoxins
On May 22nd, the EPA issued recommended concentrations for
microcystins and cylindrospermopsin at or below which human health is
protected while swimming or participating in other recreational
activities in and on the water. States, territories, and authorized tribes
can consider adopting these recommended criteria into their water
quality standards and using them for Clean Water Act purposes.
Alternatively, they can use these same values as the basis of swimming
advisories for public notification purposes at recreational waters. The
recommended criteria or swimming advisories are based on peer-
reviewed, published science and methods. For more information on
these recommendations go to https://www.eDa.aov/wac/recreational-
water-aualitv-criteria-and-methods
HABs Infoaraphics
EPA also published new
infographics that state and local
governments can use to
communicate basic information
about HABs to the public. The
infographics highlight how a HAB
may affect both people and
animals, and provide information
concerning how to identify and
respond to a potential bloom.
Downloadable and printable
versions are for two versions: a
more detailed poster for display
and another as an abbreviated
handout.

s EPA's Webinar: Planning for and Responding to HABs in Coastal Waters
On May 23rd, the Office of Water, Office of Science and Technology, hosted a webinar focusing on
HABs in coastal waters. Presentations included an overview of guidance on the control of biotoxins in
seafood, monitoring for early warning, and mitigation options for marine HABs. Additionally, The
Florida Department of Health presented on the public health implications of marine HABs in Florida.
Presentations and recording of the webinar are posted here.

Blooms, Beach Closures and Health Advisories* May 2019
* Include blooms, cautions, warnings, public health advisories, closings and detections over the State's
threshold, due to the presence of algae, toxins or both. This is not a comprehensive list, and many
blooms may have not been reported or are not actively monitored.
