Frequent Questions

Is TOC a health concern?

Disinfectants (such as chlorine) can react with natural organic matter (NOM) in water to form unintended disinfection byproducts (DBPs) (e.g., trihalomethanes) which may pose health risks. Total organic carbon (TOC) is used as an indicator of the NOM in water. By lowering the concentration of TOC, public water systems can reduce DBP formation and exposure.
