The urban Santa Ana River in California is the primary
source of recharge water for Orange County's
groundwater basin, which provides water to more than
two million residents. This study was undertaken to
determine the unidentified portion of dissolved organic
matter (DOM) in various natural surface and reclaimed
waters of the Santa Ana River Basin and to assess the
potential health risk of this material.
The most abundant organic contaminants were
anionic detergent degradation products (constituting
about 12% of the DOM), which have no known
adverse health effects. In addition, high percentages of
dissolved colloids from bacterial cell walls were found
during storm flows; these colloids foul membranes used
in water treatment. Although no significant health risks
were ascribed to the newly characterized DOM, the
authors note that even the small amounts of humic
substances deposited during storm flow periods were
responsible for significant increases in disinfection byproduct
formation potential in these waters. Includes 23 references, tables, figures.
