This paper describes a process called buffer intensity, which is the ability of a water to resist a change in pH. An example was given of the practical application of buffer intensity in a medium sized water system that uses surface water and is treated by conventional filtration. The water system collected 20 samples for pH in the distribution system monthly. Initially the pH ranged from 7-9 throughout the distribution system. The initial conditions were a pH of 7.8 and DIC of 2 mg/L. The DIC was then increased to 7 mg C/L and the pH range was reduced from 2.2 to 1.6, and standard deviation of all the pH measurements was reduced to 0.81 to 0.51. The pH was then increased to 9.2, and the pH range dropped to 0.49 and the standard deviation to 0.24.
