Scientists Monitor Algae Bloom In St. Johns

Published June 13, 2008
Environmental scientists are monitoring algae blooms from Lake Harney in east-central Florida to Doctors Lake in Clay County, the St. Johns River Water Management District announced on Friday.

The staff regularly monitors algal growth in the river and routinely collect water and algae samples, but step up the testing for toxins when a bloom is observed.

Water District spokeswoman Teresa Monson said the bloom is not unusual for summer and early fall, when the St. Johns River typically exhibits its largest blooms. The algal growth results from excess nutrients -- nitrogen and phosphorus -- from fertilizer, wastewater and stormwater runoff, along with lots of sunlight and warm temperatures
