Strategic Growth Project Update: Fluoride Fate and Transport

The geochemistry of fluoride and chemical reactions that control fluoride fate and transport in the natural environment have been widely studied and are well understood. Geochemical and reactive transport models using software like PHREEQC and Geochemists’ Workbench® are useful for evaluating processes affecting fluoride fate and transport in natural environments but have important limitations when

In 2022, we plan to expand our operations into Canada to

Are Your Fluoride Numbers Real?

Fluoride site-management decisions are informed by analytical results. Several factors, however, can affect the quality of results and cause analytical bias. Bias on reported groundwater fluoride concentrations may result from aspects of the sampling, handling, transport, preparation, and analysis stages of the sampling program. Fluoride is generally regarded as a conservative ion (i.e., persistently dissolved),
