Committee Report: Disinfection Survey, Part 1—Recent changes, current practices, and water quality
In 2007, the AWWA Disinfection Systems Committee conducted its fourth survey of drinking water disinfection practices. This first‐time online survey presented new challenges and benefits. Compared with the 1998 survey, fewer small systems (those serving populations < 10,000 people) responded and more mid‐sized to large groundwater systems responded. Ninety‐eight percent of respondents reported providing disinfected water. Chlorine gas remained the predominant disinfectant, used by 63% of respondents. Use rates for chloramine (30%), chlorine dioxide (8%), ozone (9%), and ultraviolet light (2%) increased from the prior survey. “Disinfection Contact—In Plant” (assumed for microbial inactivation) was the most frequently cited treatment. Almost half of respondents cited disinfection‐related changes since the last survey. Survey respondents appear compliant with current microbial and disinfection by‐product regulatory requirements and well positioned for compliance with future requirements.
