Phosphogypsum is a leftover from processing phosphate, which is part of making fertilizer. ... “Most of the naturally-occurring uranium, thorium and radium found in phosphate rock ends up in this waste,” the Environmental Protection Agency says.2The Florida Department of Environmental Protection says the water in the pond is primarily saltwater mixed with wastewater and stormwater. It has elevated levels of phosphorous and nitrogen and is acidic, but does not appear to be toxic. It is not radioactive.
A mandatory evacuation order near a leaking Florida wastewater reservoir near Tampa Bay that affected more than 300 homes and additional businesses was lifted Tuesday.www.google.com
Do you have a link to any article that says heavy metals are present in large quantities in the leaking pond? I couldn’t find one in a quick search.
What’s a phosphogypsum stack? Where does water come in? These questions and more, answered.
Phosphogypsum has plenty of other heavy metals as well that you wouldn’t want in the food you’re eating. Even many of the refined fertilizers themselves have more heavy metal content remaining than you would want on a food crop, or in the place the fish you eat live.
As far as I know the “acidity” of the water would make the heavy metals more soluble, meaning they’d be goin along where the water goes. This article isn’t specifically related to the matter at hand but examines heavy metal in varying ph water.
“The highest concentrations of the analysed elements were observed in acidic environment. For most metals, except for lead, an increase in the pH of the solution caused a decrease in their concentration.”
