This powerpoint presentation begins by providing a brief overview of the Los Angeles water system. A case study is presented that includes the following: in October 2007, high concentrations ofbromate were discovered in several opendistribution reservoirs; intensive investigation exposed unlikelysources of bromate; and, regulatory challenges were to determine if an MCL had been violated, to quickly reduce bromate levels, and to apply the bromate MCL to the distributionsystem. The open distribution reservoirs included the Elysian, Ivanhoe,and Silver Lake Reservoirs. A sunlight reduction study that used shade balls on the surface of the reservoirs is presented.
