In order to comply with the Stage 1 Disinfectants and Disinfection Byproducts (D/DBP)
Rule and the Stage 2 D/DBP Rule, utilities have modified and/or changed their treatment
processes, typically based on historical water quality. However, when there has been a
significant degradation in source water quality, many plants have struggled to maintain
compliance.
The objective of this study was to develop long-term planning tools (e.g., regression
models) to determine the potential impact of source water quality changes on whether existing
treatment facilities could continue to comply with current, as well as future anticipated DBP
standards. These studies also evaluated the maximum concentrations for combinations of
influent total organic carbon and bromide that the existing facilities could effectively handle, the
best timing for seasonal water quality exchange programs, and treatment costs under a worst-case
scenario. The planning tools were developed based upon actual water quality and full-scale
operational data from Metropolitan's water treatment plants. Reality checks were performed
based upon past experiences and actual plant data, which were not a part of the model
development. Includes 10 references, figures.
