This study evaluates the issue related to the mixing of waters with free chlorine and chloramine residuals in the distribution systems. For active mixing, the final chlorine residual will be reduced due to breakpoint reaction effects. For passive mixing, diffusion is a limiting process that results in a very narrow reaction zone. Both the diffusion calculation and field observations have similar conclusions: the residual cancellation due to passive mixing in the distribution system is not an issue. Includes reference, figure.
