Physical Distribution System Models for Assessing the Impact of Water Quality on Regrowth and Corrosionby Anne K. Camper,
Warren L. Jones,
Abstract: Over the past several years, there have been several new and proposed Safe Drinking Water Act (SDWA) regulations that will require many water utilities to modif treatment operations to produce a higher quality of distributed water that (a) has a reduced microbial load, (2) has lower concentrations of disinfection by-products, and (3) minimizes the potential for leaching of lead and copper. As a result of these regulations, many utilities are focusing on maintaining water quality during distribution. To evaluate water quality changes after treatment, researchers and some utilities are using laboratory/field distribution system physical models and predictive computer models. Each model serves a particular purpose in assessing water quality changes.
