Alarming Levels of Algal Toxins in St. Johns

Today, the St. Johns River Water Management District (SJRWMD) released the results from two algae samples recently taken from the St. Johns River at Doctors Lake Marina in Clay County. The test results from GreenWater Laboratories detected total microcystin toxin levels at 1120 and 4350 micrograms per liter, or more than 50 and 200 times higher than the recommended recreational exposure threshold of 20 micrograms per liter from the World Health Organization (WHO). Attached are the lab results.
