Algal Bloom Sampling Results
Sampling Schedule
DEP reviews citizen reports of algal blooms received via the online reporting form or hotline and coordinates with other agencies who are also sampling – SFWMD, SWFWMD, FWC and Lee County – to determine the sampling team to respond based on the location of the bloom relative to the sampling schedule for that day. Additional entities have reached out to offer sampling support and are added to the schedule as needed.
The department, water management districts and FWC routinely survey and sample locations in South Florida, and are prepared to collect samples if algae is present.
