This slide presentation outlines information on the role of ultraviolet (UV) disinfection in a multiple barrier approach to virus control at the Cedar Rapids Water Department where it was demonstrated for one year. Topics covered include: Cedar Rapids Water Department goals; current Surface Water Treatment Rule (SWTR) compliance status; alternatives for additional virus inactivation; breakpoint chlorination has water quality concerns; more chloramine storage; benefits of UV; flow chart of distribution system test; distribution system water quality results; Adenovirus; new stringent regulations for UV virus credit; other available virus barriers in Cedar Rapids; adding chlorine to water with ammonia significantly kills Adenovirus; sequential UV/Chloramine has 5-log Adenovirus kill; high pH provides 3-log Adenovirus kill; riverbank filtration; and, disinfection strategy.
