Although chlorination has been an effective and cost‐efficient method of disinfecting drinking water, more stringent regulation of disinfectant byproducts may cause some small water systems to consider alternative disinfection methods or minimization of natural organic matter. Among the possible alternatives are treatment using ozone, chlorine dioxide, and ultraviolet radiation. The best alternative depends on each system's particular requirements. Each alternative will require commitments from the utility‐in terms of time and costs, including additional staff members and training. The process of determining if a system needs to consider disinfection methods other than chlorination, and which methods might be most effective, involves analysis of many factors. In addition to addressing these issues, the author provides an overview of how each of the alternative disinfectants fit into the treatment train.
