Salinity levels have continually risen in the City of Camarillo’s groundwater aquifer (Pleasant Valley Groundwater Basin) over the past two decades resulting in high concentrations of chlorides, sulfates, and total dissolved solids (TDS), reducing groundwater quality below drinking water standards. Water is imported from the Metropolitan Municipal Water District (CMWD) to meet drinking water standards. The imported water currently constitutes over 60 percent of the city’s potable water supply. The City has constructed and is starting up a new groundwater treatment facility to reduce salinity levels, remove other contaminants, meet drinking water standards, and supply a local, renewable water source that reduces reliance on imported water. This presentation will inform public works agencies on how the City is reclaiming an unusable brackish groundwater supply to become more water-independent and drought resilient. Presenters will also discuss the regional and local benefits of the desalter and the treatment process used to remove/reduce contaminants in the groundwater supply to meet drinking water standards. After this session, participants will be able to:
• Explain how the City of Camarillo is reclaiming an unusable brackish groundwater supply to become more water-independent and drought resilient.
• Determine the regional and local benefits of the City of Camarillo’s desalter.
• Analyze the treatment process used to remove/reduce contaminants in the groundwater supply to meet drinking water standards.
