Dichlorobromomethane Monthly Average limit is 46 % and reported value was 62 % at M-001. |
EMWD is currently awaiting Division of Drinking Water (DDW) approval to advance this effort. Once approved and implemented, the alternative disinfection using free chlorine will allow for improved operational flexibility to meet permit requirements. Additionally, EMWD is conducting a pretreatment investigation and water quality
evaluation of the Temescal Creek discharge to identify and mitigate factors contributing to Dichlorobromomethane formation. |
