Florida is the center of phosphate mega-mining in the United States and one of a small handful of globally significant phosphate strip mine locations. At the turn of the twenty-first century, Florida extracted about 75 percent of the nation’s phosphate and 25 percent of all global phosphate rock mining. The sheer scale of the impact of this extraction on the Floridian Peninsula is immense: in 1999, 300,000 acres of land strip mined. This is one percent of the state’s surface area and is a sixteen-year-old statistic.
Stops water runoff and erosion: Gypsum improves water infiltration rates into soils and also the hydraulic conductivity of the soil. The use of gypsum can decrease wind and water erosion of soil.

Florida Phosphate Industry Refusing To Accept Safety Standard In its 2006 report, the U.S. Agency for Toxic Substances and Disease Registry stated the federal government has relied upon the ”five picocuries” per gram (radiation/mass) of soil standard at many sites and listed some in Pennsylvania, New Mexico, New York and Michigan as examples. These areas produce little phosphate rock relatively to Florida. However, Florida officials considered the threshold to be ”overly conservative,” the federal agency’s report noted.
Improves low-solute irrigation water: Gypsum is used to increase the solute concentration of low-solute water used for irrigation. Irrigation water from rivers that no longer have sources of leachable salts either penetrates poorly into soil or causes soil particles to degrade which results in low-water penetration. The problem can be corrected with surface-applied gypsum or application to the irrigation water.
GRG is also versatile in terms of available finishes. Gypsum elements can be painted with flat latex, or they can be crafted to have a wood grain texture or look like copper, aged bronze, or sandstone. Glass Fiber Reinforced Gypsum is fire resistant: Gypsum, one of the main ingredients in GRG, is a mineral that will not burn.
