Red Tide Status Report May 26, 2021

Current Conditions
A patchy bloom of the red tide organism, Karenia brevis, persists in Southwest Florida, where it was detected in 57 samples over the past week. Bloom concentrations (>100,000 cells/liter) were observed in one sample from Manatee County, five samples from Lee County, and five samples from Collier County. K. brevis was also observed at background concentrations in one sample from Northwest Florida. Additional details are provided below.

In Southwest Florida over the past week, K. brevis was observed at very low concentrations in Pinellas County (in one sample), background to low concentrations in Hillsborough County (in five samples), background to medium concentrations in Manatee County (in 15 samples), background to very low concentrations in Sarasota County (in 9 samples), very low and low concentrations in Charlotte County (in two samples), background to high concentrations in Lee County (in 17 samples), and low to high concentrations in Collier County (in eight samples). Samples collected offshore of Monroe County did not contain red tide.

In Northwest Florida over the past week, K. brevis was observed at background concentrations in Escambia County.

Along the Florida East Coast over the past week, K. brevis was not observed.

Fish Kills
In Southwest Florida over the past week, fish kills suspected to be related to red tide were reported in Manatee, Lee, and Collier counties.

Respiratory Irritation
Respiratory irritation suspected to be related to red tide was reported over the past week in Southwest Florida in Lee County.

Piney Point Report May 26, 2021

Florida Department of Environmental Protection (DEP) staff continues its oversight of the progress being made onsite with water treatment efforts through innovative technologies, along with the monitoring of the success of the sand placement repair in the NGS-South compartment.

Key status updates and response activities:

DEP has been managing water within the lined storage basins onsite to safely control water levels, respond to rainfall events and support water treatment.

Approximately 190 million gallons are held within the NGS-South compartment. Pond level readings are expected to fluctuate due to a host of factors, including wind and associated wave activity in the pond.

DEP continues to monitor and sample surrounding waterways following previous discharges. DEP’s interactive water quality dashboard details sampling locations and corresponding results to evaluate any environmental impact. Results will continue to be posted as soon as they are available.

DEP is also working collaboratively with the Tampa Bay Estuary Program (TBEP) and local governments to cover more area and collect more data. For a comprehensive view of all sampling in Tampa Bay related to Piney Point, visit TBEP’s interactive water quality dashboard
