Island residents might not be familiar with the term harmful algae blooms (HAB), but the bouts of lyngbya and red tide that have plagued the area are all too common. The National Oceanic and Atmospheric Administration (NOAA) defines the blooms as “simple photosynthetic organisms that live in the sea and freshwater that grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals and birds.”
On Friday, July 23, Suncoast Waterkeeper and Tampa Bay Waterkeeper held a public forum at the Bradenton Yacht Club to inform area residents of the threat these blooms pose and help them understand what causes them and what we need to do to address the problem.
The program began with an introduction by Suncoast Waterkeeper Chair Joe McClash and Founder Justin Bloom. The forum included presentations by Ed Sherwood, the executive director of the Tampa Bay Estuary Program, and Dave Tomasko, the executive director of the Sarasota Bay Estuary Program. Both Sherwood and Tomasko pointed to the intentional release of over 200 million gallons of waste “process” water from the Piney Point facility in Manatee County this spring as the likely cause of the devastating bloom that has killed millions of fish in upper Tampa Bay in the last month. This event was the first of its kind since 1971, when millions of gallons of partially treated sewage and wastewater were routinely being discharged into the bay.
Both Sherwood and Tomasko are seasoned scientists and also have intimate firsthand experience on local waters. Sherwood came up through the ranks at the TBEP to become its executive director in 2018 after serving as the program scientist since 2008. Sherwood is responsible for maintaining TBEP’s partnerships and continuing the bay’s science-based restoration and recovery strategies. He holds a Bachelor of Science degree in marine biology from the University of West Florida and a Master of Science degree in marine fisheries and ecology from the University of Florida. Tomasko has more than 30 years of experience on local waters. He holds a doctorate in biology from the University of South Florida, a Master of Science degree in marine biology from the Florida Institute of Technology and a Bachelor of Science degree in biology from Old Dominion University. Tomasko was also the first-ever SBEP program scientist.
A sold-out audience of more than 100 participants crowded the Yacht Club’s dining room, where they enjoyed coffee, tea and a continental breakfast during the event. Hundreds more joined via Google Meets and a Facebook Live broadcast. The presentation was also filmed by Carl Shelton of Manatee Educational Television and will be available to the public soon. Interested parties can view the Facebook Live broadcast at Suncoast Waterkeepers Facebook page.
Each presentation included supporting graphics and data that emphasized the concerns of both scientists. While there are obviously nuances and the science is constantly unfolding, a few facts really drove home the seriousness of our water quality issues. The main takeaway for this reporter was the fact that between 1980 and 2017, water quality and seagrass coverage improved significantly in Tampa Bay and Sarasota Bay. Since 2017, all those almost 40 years of gains have been lost and there are concerns that both bays could soon go the way of the Indian River Lagoon, once described as “one of the most biodiverse estuaries in the Northern Hemisphere.” That ecological treasure has collapsed and “since 2009, 58% of the seagrass in the lagoon system has disappeared, choked off from sunlight as a result of an over-saturation of nutrients in the water,” according to the St. Johns River Water Management District.
This catastrophic collapse has led to the unprecedented death of more than 841 manatees between Jan. 1 and July 2, breaking the previous record of 830 that died in 2013 because of an outbreak of toxic red tide. Dr. Tomasko explained that most of the deaths have been by drowning due to malnutrition from the lack of the seagrasses they depend on. Both scientists fear that we are perilously close to the same thing happening here if we don’t act fast. Despite the alarming statistics, Dr. Tomasko was optimistic that we could still turn this around. That will take the involvement of all stakeholders in the region from plumbers and electricians to developers, builders and – most importantly – our elected officials. While it’s easy to blame our leaders for our water quality ills, it’s important to remember that this is a shared responsibility. We the voters elected the politicians that are responsible for protecting these valuable resources. It’s critical that we do a better job vetting the leaders we choose. The future we leave for our children, grandchildren and all future generations depend on it.
