PHOSPHATE

Phosphate was discovered in the Peace River Valley north of Punta Gorda in 1881. A ridge of phosphate runs through central of Florida (New Era). The easy access to the phosphate in Florida makes it one of the top phosphate producing areas in the world (Hey-Day).

 

Because Boca Grande Pass is the deepest natural pass in Florida, a port was developed on the south end of Gasparilla Island (Peace River Valley 1890s). Originally the phosphate was barged down from the Peace River Valley to Port Boca Grande and loaded onto schooners. By 1907, the CH&N railroad was brought in to be more efficient. For the next 67 years phosphate was shipped out of the state-of-the-art port by ships from all over the world with almost no disruption (Port Boca Grande is Built).

 

 

Phosphate is found in the cell walls of all living things and formed over millions of years as dead plankton and other small creatures sunk to the ocean floor and through various chemical reactions became phosphate (New Era). Phosphate is used for many things like  laundry detergents, fertilizers, and vitamins.  Phosphate released into the watershed through stormwater runoff causes harmful algae blooms (Uses).
