Ann Arbor Controls Trihalomethanes
Many water treatment plants in the United States were not initially designed to control the formation of trihalomethanes as by‐products of existing disinfection practices. New methods were needed to meet the National Interim Primary Drinking Water Regulations for total trihalomethanes (TTHMs), so many water purveyors began modifying existing treatment processes. The city of Ann Arbor, Mich., experimented with a variety of disinfection schemes using chlorine and chloramines. Anhydrous ammonia, added to the raw water after prechlorination, reduced TTHM concentrations to required levels.
