More than 200 agricultural drains in the Sacramento River Delta contribute significant levels of trihalomethane (THM) precursors to California State Project water. It has been hypothesized that these drains, associated with crop irrigation involving highly organic peat soils, are probably responsible for the higher levels of dissolved organic carbon and THM formation potential in the California Aqueduct emanating from the delta in comparison with the principal freshwater tributaries entering the delta. The purpose of this study was to evaluate this hypothesis. It was found that the dissolved organic matter from drains is characterized by a higher molecular weight and greater THM reactivity than that found in delta tributaries. Includes 10 references, tables, figures.
