JACKSONVILLE, Fla. -- Another wave of green slime has hit the St. Johns River. The fall season outbreak is now raising concerns.
Thousands if not millions of green specks filled two small glass bottles collected by St. Johns Riverkeeper Lisa Rinaman on Monday.
"It's not worse than I've seen it before, but it's more persistent," said Rinaman.
Rinaman said it has been an ongoing problem throughout the summer but now that summer is over, the green slime should be, too.
"We're really concerned to see it this consistent this late in the season," said Rinaman. "We have a nutrient pollution problem in the St. Johns River."
According to Rinaman, the algal bloom is a symptom of that pollution. Rinaman said the algae can emit toxins that are harmful to humans and it can take up most of the oxygen in the river, which can kill marine life.
"The general rule of thumb is stay away from it, don't touch it, definitely don't drink it and don't swim in it," said Rinaman.
Once Rinaman is finished collecting samples from different areas of the St. Johns River, they'll be sent to be tested in a lab in Palatka.
