The parameter typically tested to check for organics in water quality is nitrate levels. Nitrates are a common indicator of organic pollution in water systems, particularly from agricultural runoff or wastewater discharge. High concentrations of nitrates can signal the presence of organic matter, as they are a product of the breakdown of organic materials in the presence of nitrogen. Monitoring nitrate levels helps assess the overall quality of water and potential impacts on ecosystems and human health.

While iron concentration, chlorine residual, and flow rates are important water quality parameters, they do not specifically indicate the presence of organic substances. Iron concentration relates more to mineral content and can affect taste and color rather than serve as a direct measure of organic material. Chlorine residual is used primarily to ensure water disinfection, while flow rates provide information on the volume of water moving through a system but do not indicate organic contamination.
