occurs naturally in rock formations in the earth's crust, usually as phosphate. Of high nutritive value to plants and animals, phosphates are used in fertilizers and as animal feed supplements. They are also used in the manufacture of industrial chemicals and pharmaceuticals and as detergent builders. High phosphate concentrations in surface waters may indicate fertilizer runoff, domestic waste discharge, or the presence of industrial effluents or detergents. Although phosphates from these sources are usually poly-phosphates or organically bound, all will degrade to "ortho" or reactive phosphates with time. If high phosphate concentrations persist, algae and other aquatic plant life will flourish eventually causing decreased dissolved oxygen levels in the water due to the accelerated decay of organic matter. Phosphate measurement is used to control scale and corrosion inhibitor levels in boilers and cooling towers. ( http://www.chemetrics.com/)

Can enter lakes, streams, and other sources of surface water through runoff when manure is surface applied in close proximity to them. Phosphorus is tightly held in most soils and does not leach in significant quantities, but soils do have a limit as to the amount of phosphorus they can absorb and retain. If this amount is exceeded, the excess phosphorus will leach and can contaminate groundwater and eventually surface water. The chances of phosphorus leaching increases with long-term overapplication of manure or the application on sandy soils with low organic matter content or on soils with high water tables. However, most phosphorus entering surface water comes from direct runoff and from runoff in the form of soil erosion.
