Notably, Measure PP, which did not pass recently, pertains to the General Fund and is unrelated to these water alternatives. The Water Enterprise Fund, through rates and recent bond issuance, fully funds efforts to secure alternative water sources. Alternative Considerations The Water Supply Alternatives Study also re-evaluated rebuilding existing wells (Well 5, 6 and 8) and constructing a new PFAS treatment plant. However, this option was not recommended due to the advanced age and deteriorated condition of the City's wells, which would require costly rehabilitation or redrilling. Additionally, constructing a PFAS treatment plant would significantly increase operational costs, as well as training, testing, monitoring, and reporting responsibilities. Wellhead treatment is not intended to remediate or clean up legacy or current and future source(s) of PFAS contamination in the groundwater basin but, instead, to treat and meet the drinking water standards per EPA regulations in the distribution system. Conversely, under the current Regional Groundwater Facilities Project, if test well results indicate water quality challenges, Zone 7 can address treatment needs for PFAS and other potential emerging contaminants through its existing facilities or by adding additional treatment processes for regionwide water supply needs. This shared -cost approach would save the City the expense of developing and operating a new treatment plant independently for PFAS alone, making a regional approach more cost-effective and reliable.
