Blue-green algae on the rise in St. John River, says UNB researcher

An associate professor of biology at the University of New Brunswick is warning residents about blue-green algae popping up along the St. John River this summer. Janice Lawrence says mats of cyanobacteria will probably start lifting off the river bottom and washing ashore any day now. "That's when they become dangerous," said Lawrence, who has been studying blue-green algae along the St. John River for the past three years.
