Guidance Document Change: The Guidance for Cyanobacteria Bloom Recreational Advisory Management requires revision for the Harmful Algal Bloom (HAB) response season, beginning in April 2025. The proposed revision includes the DEQ and VDH staff recommendations, which allow for more extensive and targeted monitoring of algal toxins in recreational freshwater areas during a HAB, and for using toxin data alone for recreational advisory determinations. These recommendations are based on a review of current processes for HAB monitoring and managing recreational HAB advisories, final recommendations from the U.S. Environmental Protection Agency (EPA) on protecting human health risks from incidental ingestion while recreating in freshwaters, data collected from Virginia HAB investigations with paired cell counts and toxin assays, and budget and staff efficiencies. This approach is supported by both VDH and DEQ agency secretaries.

HBA Advisory Protocol for Lake Anna
 

We have property at Lake Anna and enjoy living here.  However, over the past several years, more and more HAB advisories have been issued for certain parts of the Lake with recommendations to curtail water activities for individuals and pets.  We appreciate those HAB early warnings, however, the new protocol will delay advisories if "cell counts" no longer trigger warnings of HAB at an early stage.  Visual observations and testing for toxins is also important.  Rather than a proactive approach to public health, this new protocol would be reactive and we would potentially have very late advisories for HAB.  Not only is HAB a health risk, but it is important that there be continued funding for mitigation of HAB for those living here and visiting the Lake.  As the media learns about HAB at the Lake and it becomes known around VA, DC and MD, fewer people will be interested in coming to the lake or even living here.  They will simple go elsewhere to spend their money.  Consequently, it is imperative there be continued efforts to eliminate, mitigate, and have appropriate protocols for HAB.  Thank you for your attention to this important issue.
