Abstract
Previous research has shown that wastewater disinfection using UV light can be impaired by attenuation of the UV light as it passes through particles to reach embedded and protected microorganisms. This study determined that the UV absorption (at 254Â nm) of particles present in 10 untreated surface waters was similar to the absorption of wastewater particles. As such, it provides evidence that UV disinfection of surface waters during drinking water treatment may be impaired by the same mechanism if particles are present. The study also demonstrated that among the 10 untreated surface waters examined, there was no correlation between the UV absorption (254Â nm) of the solid particulate material, total organic carbon, total suspended solids, turbidity, or UV absorbance (254) of the bulk water.
