CHEMetrics Phosphate (ortho) Test Kits

Phosphorus occurs naturally in rock formations in the earth’s crust, usually as phosphate. 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.
