Have there been studies to assess radiation and other potential impacts from phosphate mining in communities where Mosaic operates?

Yes. The FDOH has monitored radiation levels on pre- and post-mined lands for 30 years. Their monitoring results indicate levels on post-mined lands are within naturally occurring radiation levels in soils.

Since the late 1970s, FIPR has also extensively studied and conducted research concerning radiation, waste disposal, air and water emissions associated with phosphate operations.

Most recently, there have been two independent studies by the FDOH and Hillsborough County Environmental Planning Commission (EPC) on radon emissions that may be associated with the Riverview facility’s phosophogypsum stacks (2010 and 2012-2014). Based on those studies, no elevated radon levels were observed, and FDOH concluded that the monitoring results “are generally low compared to background levels in most of the country.”
