This article discusses an effort by the township of North Shore in Northern Ontario, to explore treatment options for high levels of trihalomethanes (THMs). Based on results of a field study experiment in which aeration reduced THMs by 68 percent, the utility conducted a full‐scale pilot study on the effects of aeration on reducing THMs in the clearwell and ultimately the distribution system. Equipment and the experimental approach are discussed, along with results and study limitations including sample collection procedures, water and air temperatures, organics in the water, and clearwell ventilation.
