September 21, 2016 Report

Our monitoring indicates that water released from the gyp stack remains onsite.

Water within the Floridan aquifer in the vicinity of the New Wales facility generally moves to the west, and at a slow pace – around 500 feet per month. Please note: In our original update, we cited that the flow of water within the aquifer was approximately 1,000 feet per month. But, based on further evaluation, the pace of groundwater movement is even slower than initially estimated. That pace allows us to recover water from the gyp stack in the aquifer by pumping it through our well as shown on the graphic below. That well is located west of the gyp stack and taps into the Floridan Aquifer.

Well Testing Update

As of today, Mosaic has scheduled or collected a total of 106 well water tests through Environmental Consulting & Technology, Inc. (ECT). These are being prioritized based on their proximity to the New Wales facility.

The samples will be analyzed for minerals and other parameters that are indicative of the type of water that was released as a result of the sinkhole. Most results will be available within a few days of sample collection.

Municipal systems are not included as part of the sampling that ECT will perform. Unlike private wells, municipal water systems already undergo frequent sampling pursuant to state or federal regulations.

As a reminder, Mosaic is offering free bottled water to those who request it, until they receive confirmation that their well water has not been impacted by the water from the gyp stack. The number to call for inquiries about testing or bottled water is 813-500-6575 .

Neighbors who have requested an alternative means of testing are encouraged to receive a water test at no cost from the Florida Department of Environmental Protection.
