Getting the Most Out of Your TOC Information

Abstract

This article discusses compliance to the Stage 1 Disinfectants/Disinfection Byproducts (D/DBP) Rule and the proposed provisions of the Stage 2 D/DBP Rule. The Stage 1 D/DBP Rule focuses on low‐cost steps to optimize treatment, thus lowering DBPs. US Environmental Protection Agency's guidance says the most cost‐effective approach to controlling DBPs may involve the removal of precursors that eventually lead to byproduct formation such as total organic carbon (TOC). This article discusses TOC removal, benefits of TOC removal, and a three‐part plan to help you gather the right data and determine if your treatment plant meets the regulations.
