St. Petersburg

About 50,000 gallons of partially-treated sewage overflowed Wednesday from a water treatment plant in south St. Petersburg.

The south side of St. Petersburg - best known among locals as "Midtown" -- is a predominantly African-American area with a high rate of poverty.

A federal investigation into St. Petersburg’s sewage releases has been closed.

On a typical spring day, when it hasn't rained in a while, about 7 million gallons of raw sewage flows into St. Petersburg's southwest water treatment plant.

You wouldn't think that a region that prides itself on outdoor activities and sunshine would have problems with air pollution. But Tampa Bay had some of the dirtiest air in the state in 2015.

The report came from the advocacy group Environment Florida. It says in 2015, Tampa Bay experienced 56 dirty air pollution days. The region - which is swept with sea breezes from the Gulf of Mexico and Tampa Bay - was the worst area in the state in 2015 for both soot and smog.

More than 100 million gallons of wastewater flowed onto St. Petersburg's streets and into Tampa Bay when Tropical Storms Colin and Hermine hit last year. The city is proposing drilling six new injection wells to make sure that doesn't happen again. 

A massive sinkhole under a phosphate plant in Central Florida is dumping millions of gallons of contaminated water into the ground. West in Tampa, that city’s mayor is facing questions about his handling of a sewage spill into the bay. And in North Florida, a fight over a proposed wastewater pipeline, has surrounding counties picking sides.
