Approve Consultant Agreement with Hazen and Sawyer for Feasibility and Pre-design Analysis for PFAS Treatment for Wells 1 and 2
OVERVIEW STATEMENT:
recommendation
??Public Works is requesting approval of a consultant agreement with Hazen and Sawyer in the amount of $284,276 for feasibility and pre-design services for potential PFAS Treatment for Wells 1 and 2.

Public Works is proposing to move forward with a pre-design analysis for PFAS treatment for Wells 1 and 2 as the first step in formal design and potential construction of a treatment facility. Attachment B shows recent sample results for Supply Wells 1 and 2.
