A sinkhole spanning 45 feet (13.7 meters) in diameter opened at a Mosaic Co phosphate fertilizer facility in Florida, leaking 215 million gallons of “slightly radioactive water,” a company spokesman said on Friday.
Mosaic said the monitoring system at its New Wales facility at Mulberry, Florida, showed a decline in water levels on Aug. 27 from the retention pond of a phosphogypsum stack, a hill of hazardous waste. Phosphogypsum is a radioactive byproduct resulting from the production of phosphate.
The Minnesota-based company immediately reported the incident to state and federal environmental authorities, Mosaic spokesman Ben Pratt said on Friday. But it did not otherwise report it publicly until posting information on its website on Thursday, he said.
The leaked water is enough to fill more than 300 Olympic swimming pools.
The nearly three-week gap between detecting the sinkhole and reporting it to the public is alarming, said Jacki Lopez, Florida director of the Center for Biological Diversity.
“It’s hard to trust them when they say ‘Don’t worry,’ when they’ve been keeping it secret for three weeks,” she said.
The sinkhole, located about 30 miles from Tampa, damaged the liner system at the base of the stack, causing the pond on top to drain. Seepage continued and the sinkhole reached Florida’s aquifer, Mosaic said on its website.
Specific environmental and health concerns are the release of uranium, radium and radon gas, Lopez said. Once contaminants reach the aquifer, which extends from central Florida to Georgia, they can potentially travel hundreds of miles, she said.
“We don’t know what the long-term effects will be,” said Lopez. “If I were living in this area, and I had well water, I would be worried about my health.”
Mosaic said it had increased monitoring and sampling of groundwater and found no offsite impact. It also said it pumped water out of the affected pond to reduce the volume of leakage.
The company said it is attempting to recover the water through production wells on site.
The incident has not interrupted operations at the facility.
Mosaic shares fell 1.7 percent, declining with other major fertilizer producers.
In 2015, Mosaic reached an $800 million settlement with U.S. regulators over its waste management practices at plants in Florida and Louisiana.
Take a look at this amazing resource I’ve just discovered, it’s Dr Elaine Inghams lessons on the soil food web, as well as creating your own composts and compost teas/extracts. The information contained hereinafter is often behind a paywall.
“Elaine Ingham, Chief Scientist at Rhodale Institute came to Hawi, Hawai’i in July 2012 to deliver a 5 day seminar dedicated to studying, understanding, and improving our soil biology to assist in ecologically sound agricultural practices. This is where I got my introduction to the microscope and learned much of it’s importance. This was some of the best 30 hours of class ever, and I often re-watch this epic series to refresh myself and discover more as I tune my own magnification of understanding this microscopic wonderland.” – Drake of Natural Farming Hawaii.

“Neem seed cake also reduce alkalinity in soil, as it produces organic acids on decomposition. Being totally natural, it is compatible with soil microbes, improves and rhizosphere microflora and hence ensures fertility of the soil. Neem Cake improves the organic matter content of the soil, helping improve soil texture, water holding capacity, and soil aeration for better root development.” – Wikipedia
There it is, another added benefit of the Neem Cake is its ability to create a favourable growing environment on the more alkaline soils. So not only are you getting an excellent source of organic nutrients and the “pest and disease resistance” it’s also working as a soil conditioner too.

Paul’s central premise is that habitats have immune systems, just like people, and mushroom forming fungi are the foundation of the foodwebs of land based organisms.
Our close evolutionary relationship to fungi can be the basis for novel pairings that lead to greater sustainability and immune enhancement. As we are now fully engaged in the 6th Major Extinction (“6 X”) on planet Earth, our biospheres are quickly changing, eroding the life support systems that have allowed humans to ascend. Unless we put into action policies and technologies that can cause a course correction in the very near future, species diversity will continue to plummet, with humans not only being the primary cause, but one of the victims.
Fungi, particularly mushrooms, offer some powerful, practical solutions, which can be put into practice now. Paul will discuss his groundbreaking research utilizing their cellular networks to create molecular bridges governing the evolution of sustainable habitats. The implications of his research are far-reaching and could spark a paradigm shift to a better future.
A biochar-based soil improver, enriched with species of mycorrhizal fungi, actinomyces bacteria and trace elements is helping to combat the root-knot nematode – significantly increasing yields for organic tomato growers in Portugal.
Biochar is a highly porous, high carbon form of charcoal used to improve soil nutrition, growing conditions and soil structure. It is made from any waste woody biomass that has been charred at a low temperature with a restricted supply of oxygen, a process called pyrolysis. This process results in a stable form of carbon that is removed from the atmospheric carbon cycle when added as a soil amendment.
“Where we have incorporated Carbon Gold Soil Improver in the very sandy soil at our Portuguese nursery we have seen a 7% yield increase and a lower level of nematode infestation than areas that were not treated.” – Paul Howlett, Head of Agronomy at Vitacress Tomatoes
Vitacress Tomatoes (formerly Wight Salads) trialled Soil Association and SKAL approved enriched biochar from UK biochar company, Carbon Gold, from June 2013 to April 2014 in order to improve the sandy soils at their Portuguese nursery. They applied 2kg per square meter to a 5 hectare trial plot taken to a depth of 30cm, analysing the outcomes against a 5 hectare control area with the same crop.
The increase in crop yield was significant. By week 24 they realised a 7% higher yield, (an additional 0.9kg per m2) compared to the 5ha control plot. This equated to an additional 2,600kg Piccolo Cherry on the Vine tomatoes.
In the Vitacress trial plots it became evident that the colonies of mycorrhizal fungi, using biochar as a refuge in the soil, were able strike out at parasitic Meloidogyne nematodes, enticing and devouring the microscopic pests and protecting the plant roots from attack.
Field investigations between 2002 and 2011 identified soil structural degradation to be widespread in SW England with 38% of the 3243 surveyed sites having sufficiently degraded soil structure to produce observable features of enhanced surface-water runoff within the landscape. Soil under arable crops often had high or severe levels of structural degradation. Late-harvested crops such as maize had the most damaged soil where 75% of sites were found to have degraded structure generating enhanced surface-water runoff. Soil erosion in these crops was found at over one in five sites. A tendency for the establishment of winter cereals in late autumn in the South West also often resulted in damaged soil where degraded structure and enhanced surface-water runoff were found in three of every five cereal fields. Remedial actions to improve soil structure are either not being undertaken or are being unsuccessfully used. Brown Sands, Brown Earths and loamy Stagnogley Soils were the most frequently damaged soils. The intensive use of well-drained, high quality sandy and coarse loamy soils has led to soil structural damage resulting in enhanced surface-water runoff from fields that should naturally absorb winter rain. Surface water pollution, localised flooding and reduced winter recharge rates to result from this damage. Chalk and limestone landscapes on the other hand show little evidence of serious soil structural degradation and <20% of fields in these landscapes generate enhanced runoff.
