Information on Total Organic Carbon:

Total Organic Carbon (TOC) Organic matter plays a major role in aquatic systems. It affects biogeochemical processes, nutrient cycling, biological availability,chemical transport and interactions. It also has direct implications in the planning of wastewater treatment and drinking water treatment. Organic matter content is typically measured as total organic carbon and dissolved organic carbon, which are essential components of the carbon cycle.
