Nitrate Monitoring Helps With Decision Making To Optimize Well Blending

A water utility in New York State that provides groundwater to residents from hundreds of wells in a rural area required real-time monitoring to ensure that nitrate levels are maintained in compliance with the drinking water regulations. Some of the wells in the region have high nitrate concentrations while others do not. The water utility manages this situation by blending waters from clean wells with nitrate contaminated wells to ensure that the finished product water has nitrate levels well below the regulatory limit of 10 mg/L NO₃ as N.
