This powerpoint presentation begins by providing a brief overview of total organic carbon (TOC) and TOC and disinfection byproduct (DBP) regulatory/compliance information. Reasons for measuring TOC for security monitoring are presented, along with an overview of TOC analyzers and other related technology. Conclusion for online TOC analysis for security monitoring include the following: on-line water quality reporting used to protect vulnerable distribution system; TOC deemed one of the best parameters to identify contaminant; Stage 2 DBPR switch to chloramines makes TOC an even more important parameter; dual-use technology: Process Optimization/ DBP control; and, TOC technology can be easy to use with calibration stability. Includes tables, figure.
