EPD's Inorganic Laboratory analyzes environmental samples for analyztes such as: Ammonia, Nitrate/Nitrite, Total Phosphorous, Nitrogen (TKN), Total Organic Carbon, Biochemical Oxygen Demand, Chemical Oxygen Demand, Turbidity, Color and Suspended Solids. These parameters give a general, overall view of Georgia's water quality. They are important in the monitoring of agricultural runoff to lakes and streams, pollution control plants, background monitoring as well as ensuring facilities are meeting their permitted discharge limits.
In addition, Nitrate/Nitrite, Sulfate, Cyanide, Phosphates and Total Organic Carbon are analyzed on Drinking Water samples throughout the state as part of the Safe Drinking Water Act. High nitrate (found in fertilizers) levels have been implicated in toxicity with infants. Sulfates and Organic Carbon can impart taste or odor to drinking water.
