This powerpoint presentation begins by providing a brief overview of the Stage 2 Disinfection Byproduct Rule (DBPR) and Total Trihalomethane (TTHM) Example, and localized treatment for DBP. Project objectives were to: evaluate effectiveness of several treatment processes; determine DBP reformation potential; develop model for predicting treatment effectiveness and reformation potential; link treatment model with hydraulic model; and, develop tools for estimating cost. Pilot testing is presented, along with air stripping, granular activated carbon/biological activated carbon (GAC/BAC), reformation of TTHM/HAA5, modeling DBP treatment and reformation, localized treatment evaluation model, and implementation and regulatory considerations. Presentation summary includes the following: can meet limits with blending; reformation can be modeled, but must be calibrated for each system; excel model available that summarizes all work from the study; and, implementation and regulatory considerations will be state- and location-specific. Includes tables, figures.
