Phosphate (PO43-) is a polyatomic anion of phosphorus and oxygen. For the Beaver Run Project, phosphate is detected and quantified by suppressed anion chromatography. Our current limit of detection is xx ppm, and our current limit of quantitation is xx ppm.

Sources of Phosphates

"Phosphates enter waterways from human and animal waste, phosphorus rich bedrock, laundry, cleaning, industrial effluents, and fertilizer runoff."[1]

In uncontaminated water, the typical level of phosphate is around 0.01-0.03 ppm. If levels are increased above this, phosphate can start to overstimulate plant growth and death rates. In addition, plants cannot decay quickly enough as new plants grow, and the detritus at the bottom of the water body can start to build up over time, causing a host of problems. The general threshold value for this type of problem is >0.1 ppm phosphate.[1]
