This article reports on a situation in Dustin, a small community in rural Oklahoma, where red‐water complaints, elevated turbidity, and low chlorine residuals that had occurred occasionally over the years became more frequent in 2001. This led to Total Coliform Rule violations and boil‐water advisories. Chemically cleaning most of the infrastructure has helped eliminate excess chlorine demand and reduce the red‐water and turbidity complaints. The article describes the methodology the City of Dustin used to evaluate the effect of chemical cleaning on its water quality, the chemical cleaning process itself, residual testing, and the persistent problem of high disinfection byproduct concentration.
