Document Description
The California Department of Public Health (DPH) establishes the water quality standards that EVWD is mandated to meet. Among these standards is a maximum contaminant level (MCL) for disinfection byproducts (DBPs). DBPs are primarily formed when a disinfectant such as chlorine reacts with naturally occuring organic material in the source water. Currently, compliance with the MCL for DBPs is achieved through compliance with the Stage 1 Disinfectant and Disinfection Byproduct Rule (Stage 1 Rule). Compliance is achieved when the average of all samples collected from throughout the District's distribution system is below the Stage 1 Rule MCL. Additionally, treatment requirements for total organic compounds (TOC) were waived because Stage 1 Rule MCL's were met and operation of the current approved treatment process could not be adjusted to improve TOC removal. Recent circumstances and new water quality regulations along with the anticipated increase in the demand for water within the District's service area have required EVWD to consider upgrading and expanding the treatment capacity of Plant 134. The newly promulgated Stage 2 Rule for Disinfectants and Disinfection Byproduct Rules (Stage 2 Rules) will now require that compliance with the MCL be met at each sampling location and systemwide averaging will not be allowed. This includes compliance with TOC removal requirements. The Stage 2 Rule becomes effective in April 2012. In addition to these regulatory requirements that have and will continue to affect EVWD's water supply system, the demand for water continues to grow within the District. The satisfy this demand, EVWD has identified the upgrading and expansion of Plant 134 as a necessary component of its overall water supply system.
