The Des Moines Water Works, in Des Moines (Iowa), survived the severe drought of 1988 without any water supply problems. However, in early 1989 the utility began experiencing some strange phenomena including an increase in the organic loading of raw water and a septic odor on filters that had been backwashed and placed on standby that could only be attributed to the drought. The article describes the actions taken by the utility to discover the cause of the odor, the solution: filter super chlorination, and the final analysis that it could not be determined what caused the odor.
