Gwen Graham says Florida needs a governor who will fight to protect clean water, unlike, she said, Gov. Rick Scott.
"When a sinkhole began dumping toxic water in Florida's aquifer, Rick Scott tried to cover it up. I worked with the press to expose the secret sinkhole and hold Scott accountable," she tweeted July 18.
Graham is one of five Democrats seeking the party's nomination in the Aug. 28 primary to replace Scott, who is term-limited and running for U.S. Senate.
Graham's tweet linked to a 2016 Politico article in which Graham, then a congresswoman, was quoted blasting the state over its handling of a sinkhole at Mosaic's Polk County phosphate plant.
Here's what Graham's tweet has a point about: Scott's administration, more specifically the Department of Environmental Protection, kept quiet about the sinkhole for weeks, later saying it didn't know it was a sinkhole.
But she went too far in stating that Scott himself "tried to cover it up." Her tweet also leaves out the actions Scott took once he did learn about the sinkhole.
The 45-foot-wide sinkhole opened underneath a gypsum stack at a Mosaic phosphate fertilizer plant, dumping at least 215 million gallons of contaminated water into the Floridan Aquifer over three weeks.
Mosaic workers became aware of the leak on Aug. 27, 2016, and notified the department on Aug. 28. State inspectors arrived within 24 hours. Their initial report didn't use the word "sinkhole," but "water loss incident."
Environmentalists and the media called for more transparency by the state government. But state law at the time did not require the department to inform the public about a spill into the aquifer if it had not spread off-site. DEP officials described their response to the spill as going "above and beyond the requirements of Florida law by working with Mosaic to notify the nearest adjacent homeowners who may want their drinking water wells tested."
Jon Steverson, DEP secretary at the time, said he didn't know it was a sinkhole, which was why he didn't tell Gov. Rick Scott about it until Sept. 16, 2016, the day after it hit the news.
"I knew at the time in late August that there was a water loss incident," Steverson told reporters weeks later. "I was not aware of the sinkhole until a much later point in time."
Not announcing the incident, which was allowed under the law at the time, is not the same as a "coverup," which could imply that state officials and Scott schemed to hide the information. Mosaic apologized for not notifying the public sooner.
Once Scott was notified, he took action during the next couple of weeks.
Responding to criticism from Graham at the time, Scott spokeswoman Jackie Schutz told the Tampa Bay Times that Scott had directed the DEP to expedite its investigation and asked the Florida Department of Health to work with the DEP to ensure drinking water was safe.
Scott initially defended his agency by saying state law didn't require the DEP to notify anyone unless the pollution left Mosaic's property.
"Within 24 hours after they (the DEP) were notified, they started the investigation,'' Scott said Sept. 22. "If somebody's done anything wrong, we're going to hold them accountable.''
But days later, Scott declared the law "outdated" and announced a temporary emergency rule that included 24-hour public notification requirements. He also vowed to propose legislation for the upcoming session that would make such a policy permanent.
"I am demanding any business, county or city government responsible for a pollution incident to immediately tell the public," Scott said. "That is common sense and our residents deserve that."
A judge later said that the Legislature would have to set such a rule change, and it did just that in 2017 when it unanimously passed a bill signed into law by Scott.
What was Graham's role? She spread the word about the sinkhole through statements to the media. Graham criticized the state's response, called for an investigation and filed public records requests to Scott's office and the environment protection department seeking electronic communications about the sinkhole.
Graham spokesman Matt Harringer didn't point to any evidence that Scott himself had covered up the sinkhole, as her tweet indicates, but said his administration did and that the buck stops with the governor.
"It is completely fair to use 'Rick Scott' and 'his administration' synonymously," Harringer said. "The governor is the ultimate head of the Department of Environmental Protection — and often takes credit for their actions."
Graham exaggerates by stating that Scott tried to cover up the sinkhole. News reports show that the head of the environmental protection department didn't inform Scott until the media reported about it, which happened about three weeks after the sinkhole started.
Graham's tweet went further than past statements about the issue by squarely blaming Scott. The jab does not account for actions he took after he learned about the sinkhole, including an emergency order to change the notification rule and calling for a permanent law change about public notification (which he signed).
