Efforts by utility managers, especially of some small water systems, to comply with the US Environmental Protection Agency's (USEPA's) new Ground Water Rule may soon include the addition of chlorine to their systems for disinfection. However, depending on water quality characteristics and the type of pipe metal, the addition of chlorine may increase internal corrosion of the distribution system. This, in turn, may push a system out of compliance with USEPA's 1991 Lead and Copper Rule for system corrosion. If corrosion does increase, pH adjustment or the addition of orthophosphate as a corrosion inhibitor, can help control the problem. No matter the situation, the authors stress the need for routine monitoring of the system so that chemical levels can be adjusted appropriately in the event of corrosion.
