Utilities face new challenges as they strive to comply
with multiple, simultaneous regulations aimed at
enhancing drinking water quality. For example, many
utilities must comply with regulations for both corrosion
control and residual disinfection. Today utilities
are considering converting from free chlorine to chloramines
for greater residual stability and better compliance
with the Total Coliform Rule as well as the more
stringent requirements of the Disinfectants/Disinfection
Byproducts Rule. This article identifies several key
issues for predicting the effects of disinfectant change
on lead and copper corrosion and release into drinking
water supplies based on information currently available
in the literature. The key issues associated with a
change in disinfectant that potentially could affect
corrosion and lead and copper release in drinking
water systems are identified in order to provide a better
understanding of potential water quality effects associated
with a change in disinfectant. This information
can help utilities assess their systems' potential risk of
lead and copper release after implementing a change in
disinfectant. Includes 79 references, figures.
