| JACKSONVILLE, Fla. -- The foam found floating in the St. Johns River has returned. It turns out that the foam never really went away, according to Riverkeeper Neil Armingeon. He got reports of the foam in July and August, but said it seemed to go away for a while. But more reports started pouring in for some areas along the river in November. Now, Armingeon said, the foam is back. In July, the state Department of Environmental Protection ruled that the foam did not contain cyanuric acid, a chemical that's normally used to clean swimming pools. DEP investigators remain unsure of what is causing the foam. |
