Addition of powdered chalk
or finely ground limestone of commercial
technical grade calcium carbonate will react with the solution to
plus calcium carbonate. This process removes the fluoride and
the phosphate from
the solution. The water coming off after one or two treatments
drinkable (but I wouldn't recommend it). The solid
fluorapatite can be buried.
Fluorapatite is a common mineral in our western hills.
