First Quarter 2017 Well Samplings for Residents in Four Mile Radius to Start Shortly
Environmental Consulting & Technology, Inc. (ECT) soon will contact residents that live within a four miles radius of the sinkhole, and who previously had their drinking water well sampled, to schedule their first quarterly well test for 2017.
ECT is scheduling these samples and will test the drinking water wells as described in the consent order.

Safety is an Integral Part of Remediation
At Mosaic Fertilizer, we believe employee safety is a core value. In fact, we have an ambitious vision: the relentless pursuit of an injury-free workplace. Because of our commitment to safety, we have a strong safety culture and a strong safety record.
All job sites have their own unique hazards and risks, and working to remediate the sinkhole while conducting routine operations adds additional complexity to the jobsite. The heightened amount of activity at the facility warrants an even greater emphasis on safety.
Early on, we established a safe zone around the sinkhole to specify a perimeter for personnel and equipment. The perimeter allows Mosaic Fertilizer employees and its contractors to work near the sinkhole safely.
Our new access roads from the base to the top of the gypstack integrate safety features. They are equipped with various traffic caution signs, and have been built wide enough and strong enough to support vehicle traffic and heavy equipment.
We recently installed sensing equipment to monitor movements or vibrations in and around the gypstack, if they were to occur.
And we’re making new investments in technology to protect our teams against certain weather risks. We’re installing a new detection system to provide earlier notice when lightning is in the area.
We have established detailed safety standards, like wearing reflective and protective equipment. These standards are in addition to any general safety standards that our contractors bring to a worksite.
Activities on the gypstack are subject to a Job Safety Analysis (JSA). The JSAs outline the hazards involved with those tasks and specify steps to mitigate those hazards.
As part of our focus on safety, we have emergency response protocols and train our teams to use them.
Finally, safety is not a one person job. We all have a responsibility to look out for one another. We have procedures to stop work in the event that unsafe events or practices are observed.
The sustainability of every organization begins with the health and safety of its people. We will continue to remediate the sinkhole with safety as a core consideration.

New Wales Community Well Sampling Progress as of 1/11/17
This map provides an at-a-glance view of community well sampling progress associated with the water loss incident (WLI) at New Wales. Per the legend:
- Blue dots are representative of individuals and/or households who have requested well tests.
- Green dots signify well test results that show no impacts from the New Wales WLI.
- Purple dots stand for well test results that show no impacts from the New Wales WLI, but not all results meet quality standards; one well beyond range not shown.
- To date, well tests show no impacts from Mosaic.
Well tests by ECT, the third party company coordinating and collecting samples, are being performed in accordance with the Florida Department of Environmental Protection’s (FDEP) Standard Operating Procedures.

Remediation Update #7
This post focuses on grouting preparations and the management of recovered water.
Assembly of the onsite batch plant, where grout will be produced before being injected, is nearly complete. The colored mounds shown are raw materials, including sand and pea gravel, which will be used as ingredients to prepare the grout. The equipment will be tested to ensure the grout meets specifications before grout injection begins.
Management of Recovered Water
Mosaic Fertilizer is undertaking additional steps to manage recovered water from the sinkhole, including the construction of a system to treat recovered water. The first phase of the treatment system was commissioned in late December and the second phase is expected to be complete in February 2017. The system treats impacted water collected from the recovery well by ultrafiltration and reverse osmosis. The system operation will complement Mosaic Fertilizer’s existing water management practices. Water recovered or treated may be put into productive use or routed to our onsite water management system, after which it may be directed to our permitted outfall. Our discharge has been and remains subject to rigorous water quality standards as described in our discharge permit.

Remediation Update #6
This post focuses on the progress made at the gypstack.
Mosaic Fertilizer completed drilling the P-4B recovery well, and after it commences operation, it will replace P-4 as the primary recovery well. Additionally, Mosaic Fertilizer started drilling the P-5 recovery well which will provide additional recovery capacity if needed.
Piezometers and other monitoring equipment were installed in the gypstack.
