Advanced Techniques for Monitoring Changes in NOM and Controlling DBPs under Dynamic Weather Conditions

This project developed an effective on-line monitoring strategy and response system to detect changes in the character and amount of NOM and its associated DBP precursor concentration that occurs (1) during current operating conditions, (2) during extreme weather events, and (3) under future climate change scenarios. The project evaluated the ability of advanced on-line instrumentation utilizing UV absorbance spectral derivative measurements to detect changes in the concentration and characteristics of NOM associated with increased DBP formation potential.
