JACKSONVILLE, Fla. (AP) — An environmental group says water samples from an algae bloom in a northeast Florida river show toxin levels up to 100 times higher than what's considered safe by the World Health Organization.
The St. Johns Riverkeeper is warning people to stay away from the St. Johns River until the bloom dissipates.
The Florida Times-Union reports that Riverkeeper Lisa Rinaman outlined what she called "alarming levels" of microcystin algae toxin to the Jacksonville Waterways Commission this week.
Rinaman said she collected samples Monday along the Jacksonville University shoreline. She said toxin levels may have been particularly high near the shoreline, where algae clings to the top of the shallow water.
A St. Johns River Water Management District spokeswoman says the agency tracked algae blooms this summer without finding similar readings.
