COLUMBIA — Organic matter in nine out of 14 of Columbia's wells is contributing to the formation of a carcinogen in the city's drinking water, a new study by MU researcher Enos C. Innis has found. The study was funded by Columbia Water and Light in response to elevated levels of trihalomethanes, which are carcinogenic, reported in the city's drinking water in 2007.
