Problem: Lack of information about the concentration of dissolved organic compounds (DOCs) in the raw river influent for a potable water utility often resulted in excess chemical usage and need for numerous grab samples.

Situation: The utility processes 16 million gallons a day of water. Several neighboring towns rely on it for supply. Influent sources for the water utility include a river, deep and shallow wells, and a pumped-water storage reservoir. The versatility in source water options and resulting treatment strategies provide the staff with a process train that can be tailored to maximize efficiency in chemical use, while adapting to changing river conditions.
