Well 56 Wellhead Treatment Project

Well 56 Wellhead Treatment Project

Eastern Municipal Water District (District) proposes to implement the Project to address per- and poly-fluoroalkyl substances (PFAS) concentrations in the groundwater pumped at the District’s existing Well 56, taken offline in February 2019. The District proposes to acquire real property to provide a suitable location for the wellhead treatment facility and has identified a total of five potential sites (Proposed Project and Options 1-4). All but one site is clustered around the intersection of Ramona Expressway/ Indian Avenue. One site is the District’s existing Well 59 at the Indian Avenue/Nance Street intersection. The site options range in size from approximately 0.6 acres to 15 acres. Depending on the site selected, pipelines would be construction in a portion of the public rights-of-way of local streets, primarily Indian Avenue. Construction is expected to require between 5 and 18 weeks, depending on site, and to be operational in late 2024.
