I am against the proposed change in guidance for issuing Cyanobacteria Bloom Recreational Advisories. The basis for the change relies on EPA 815-R-15-010, "Recommendations for Public Water Systems to Manage Cyanotoxins in Drinking Water June 2015", which has little to do with Recreational Water Quality. Drinking water quality is measured continuously while recreational water quality is measured at best once a month. The proposed change will delay the issuances of swimming advisories significantly, thereby putting the public at unnecessary increased risk.
