Executive Summary Water Supply Alternatives Study <br />ES-2 <br />DRAFT for review purposes only. Use of contents on this sheet is subject to the limitations specified at the end of this document. <br />Water Supply Alternatives Study-Draft Report.docx <br />The Study involved a multi-step process to identify and screen an inclusive list of potential water <br />supply options. The initial screening resulted in identifying four alternatives for further consideration: <br />•Alternative 1 – Baseline Project (PFAS Treatment and Wells 5, 6, & 8 Rehabilitation) <br />•Alternative 2 – Reduced Baseline (PFAS Treatment for Well 8 only) <br />•Alternative 3 – Two New City Wells (West of PFAS plume) <br />•Alternative 4 – 100% purchases from Zone 7 <br />The Study involved an evaluation of relative benefits, costs, and tradeoffs to identify a preferred <br />alternative: Alternative 3 (Two New City Wells). The Study outlines an implementation plan for <br />Alternative 3, as well as a contingency plan for how to proceed if the outcome of predesign activities <br />indicate that implementation of Alternative 3 (Two New Wells) is not feasible or less favorable than <br />anticipated due to cost estimate refinements, groundwater quality issues, and/or production <br />limitations.
