The purpose of this study was to assess the role of natural organic matter (NOM) on disinfection efficacy using twotypes of disinfectants (Clsub2/sub and ClOsub2/sub). B. subtilis spores were used as a surrogate formonitoring disinfection efficacy.The role of natural organic matter was tested using two series of experimental assays.Initially, assays were conducted in ultra-pure buffers waters supplemented with various NOMextracts. Secondly, confirmation assays were performed on several raw (untreated) surfacewaters. Includes 11 references, figures.
