Algal Bloom Response Team

To ensure the health and safety of our state’s residents and visitors, the Florida Department of Environmental Protection is committed to keeping Floridians updated  on current algal blooms and how the state is responding to protect human health, water quality and the environment.
DEP, the five water management districts (WMDs), the Florida Department of Health (DOH), the Florida Fish and Wildlife Conservation Commission (FWC) and the Florida Department of Agriculture and Consumer Services (DACS) all work together to respond to algal blooms, each with a specific role. This “bloom response team” coordinates activities based upon the nature of the bloom event.
The algal bloom response team takes all algal blooms seriously and all federal, state and local agencies will continue to respond as quickly and efficiently as possible to both observed and reported algal blooms to ensure the health and safety of Floridians, visitors and our natural resources.

Monitoring and Testing

DEP and Florida’s water management districts frequently monitor Florida’s water quality, and routinely collect algal bloom samples as soon as they are observed as part of this effort. In addition, staff can be deployed to take additional samples in response to reported blooms – whether from a citizen, other response team agencies or other sources.
