Potential Solutions: USDA funding new well and treatment for that well. CDPH Prop 84 planning grant is investigating treatment on 2 existing wells. DWSRF program will be funding all treatment, even on the new Well 6 to be constructed using USDA funds. - Plan, design and construct media filtration systems at each well. - The proposed project will consist of drilling a new well to replace Well 2. The new well site will be located on property that District owns which is located about ½-mile away from the Well 2 site. The replacement well would be designed to replace the existing well capacity. The new well will NOT increase capacity.The project will be implemented in phases. In phase 1 a pilot hole will be drilled to a depth of up to 1,200 feet and zone testing will be conducted. The intent is to isolate a zone with desirable water quality characteristics such that arsenic treatment can be avoided or the cost of such treatment can be minimized. A final production well will be drilled and constructed based on the results of zone testing.In phase 2 the well site improvements will be completed. It is anticipated that site improvements will consist of furnishing and installing the well pump; site piping; electrical service, power and controls; and completing site grading and fencing. Site improvements will include treatment facilities if it is determined that treatment will be required. The District intends to relocate and utilize existing Well 2 treatment equipment at the new well site if treatment is required.The District is beginning design of phase 1 of the project due to the urgent nature of the problem.
