2024-09-04Resolution 24-9-4C: Settlement Agreement and Release — Highline Water District and Port Of Seattle Regarding Tyee Well PFAS Contamination
Highline Water District reached a settlement with the Port of Seattle after PFAS chemicals, likely originating from Seattle-Tacoma International Airport operations, were found to have contaminated the District's Tyee Well, forcing the District to suspend well operations in June 2022.
