Piney Point Monitoring
Jump to UpdatesWhat is Piney Point?
- Piney Point is the site of a former phosphate processing plant located on 676 acres of land in northern Manatee County, Florida near the coastline of lower Tampa Bay.
- First built in 1966, the plant produced fertilizer for decades until it was abandoned in 2001, leaving in place phosphogypsum stacks holding millions of gallons of wastewater.
- Phosphogypsum is a byproduct of the phosphate mining process and can be toxic to both humans and the environment.
- An emergency release of contaminated water from the aging stacks into Tampa Bay has occurred numerous times over the years. Nuisance and harmful algal blooms have usually followed these events.
Regional Response and Monitoring Plan
- From March 30th to April 9th, 2021 approximately 215 million gallons of wastewater from Piney Point were released into Tampa Bay.
- The Tampa Bay Estuary Program mobilized a coordinated environmental monitoring response to understand conditions immediately prior to, during, and after the onset of the discharges to Lower Tampa Bay.
- Partners throughout the region are modelling the plume trajectory and collecting water quality, benthic, seagrass, and fisheries monitoring data in an effort to monitor Tampa Bay’s response to this event.
