The EPA prohibits the use of phosphogypsum because of the radioactivity. An exception is made for phosphogypsum with an average concentration of less than 10 pCi/g radium which can be used as an agricultural amendment, but for no other use. Phosphogypsum in north Florida has 10 pCi/g radium. Central Florida phosphogypsum averages 26 pCi/g ...
Wallboard plants are sited in close proximity to power plants for access to raw material, with a considerable investment involved. Thus, FGD gypsum used for wallboard manufacture is a product rather than a waste or discarded material. This use and similar uses of CCR that meet product specifications would not be regulated under the final rule."

Also referred to as hydrous calcium sulfate (), gypsum is mined from deposits formed by ancient seabeds as a raw material for many different manufacturing, industrial, and agricultural uses. Over 80% of the gypsum mined is used in manufactured products such as drywall.
In Building Materials in Civil Engineering, 2011. Building Gypsum. Gypsum is an airhardening materials mainly consisting of calcium sulfate. And its products have many excellent characters, commonly used in construction. There are various kinds of gypsum binding materials, such as building gypsum, highstrength gypsum, anhydrite cement, and hightemperaturecalcined gypsum.
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
The material is then dewatered and processed; the end product is a consistent, finely divided powder. This process is known as flue gas desulfurization (FGD), and the gypsum produced is known as FGD gypsum. The term FGD gypsum is the name most often used by generators of the material.
