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. Includes 28 references, tables, figures.
