Wastewater Hazards in Southwest Florida Spark Environmental Concerns Across the State and Beyond

Over the last week hundreds of millions of gallons of wastewater have spewed from a former fertilizer plant in Piney Point, Florida, which was abandoned in 2001 and taken over in 2006 by the Florida Department of Environmental Protection. The location is adjacent to Tampa Bay, a 400-square-mile body of water that separates Tampa, Clearwater and St. Petersburg and is full of fish, crabs, seagrass, dolphins, manatees and seabirds of every kind.

The state plans to close Piney Point, scientists are trying to forecast what comes next and environmentalists fear algal blooms and fish kills (also known as fish die-offs).

“There are hundreds if not thousands of these waste storage ponds in the United States and each one is a ticking time bomb,” says Villanova University’s Metin Duran, PhD, an expert on the biological processes of environmental engineering, including public health microbiology and biological processes for waste management.

“The last major disaster was in December 2008, when a 40-acre pond used by Tennessee Valley Authority for the coal-burning Kingston Fossil Plant collapsed. The aftermath included damage to the area’s ecosystem and lawsuits.”

Regulations regarding waste storage ponds are at the state level, and they aren’t very strict, says Dr. Duran. “Though there are strict design and groundwater monitoring requirements to ensure waste does not cause groundwater pollution, these waste impoundments are prone to have issues under extreme weather events, such as heavy rains. With the increased frequency of such events recently, there is a risk that more of such may fail.”

Dr. Duran adds that it can be difficult to predict short- and long-term effects of the Florida case, but the reported low-level radioactive contamination could cause major damage to aquatic life and properties—and that phosphorous and nitrogen would cause eutrophication in Tampa Bay as well.
