New Wales Water Loss Incident

Well Water Monitoring Remains a Priority

Confirming that the lost process water has not impacted offsite drinking water wells remains a priority for Mosaic Fertilizer since the sinkhole occurred last fall. Private drinking water wells can naturally vary in water quality for a variety of reasons, but our well sampling program is in place to analyze parameters and constituents that would be indicative of the lost process water, consisting of:

• pH;
• Conductivity;
• Turbidity;
• Sodium;
• Sulfate;
• Total Dissolved Solids (TDS);
• Fluoride; and
• Gross Alpha.

To date, nearly 1,800 samples continue to show no impacts from the sinkhole.

In general, laboratory water sample results evaluate the concentration of a certain constituent in the volume of water sampled. They typically are reported to well owners as milligrams per liter (mg/L) or micrograms per liter (µg/L).

Soil sampling is not part of this monitoring program. By way of background, soil samples evaluate the concentration of a given constituent in a specified amount of soil sampled. Those results typically are reported as milligrams per kilogram (mg/kg) or micrograms per kilogram (µg/kg).

As specified in the consent order with FDEP, we will continue well water monitoring efforts through calendar year 2018.
