Full Description

Disinfection byproducts (DBPs) in drinking water are formed by the reaction between natural organic matter (NOM) and chlorine or other disinfectants. NOM characteristics affecting DBP formation potential in 17 small Alaskan water systems were investigated. Dissolved organic carbon (DOC), UV-254 and color were measured and correlated to the DBP formation potential for each source-water. It was found that UV-254 and specific ultraviolet absorbance (SUVA) acted as excellent indicators of the total DBP formation potential. The sample waters were also subjected to membrane ultrafiltration in a pressurized cell in order to achieve discrete molecular size fractioning of the NOM. SUVA was calculated for each size fraction to determine whether UV absorbance, and hence the maximum DBP formation potential, varied with apparent molecular size. Includes 6 references, tables, figures.
