Lower Issaquah Valley PFAS cleanup sites

Comment on cleanup documents

April 22, 2024 - June 6, 2024, 11:59 p.m.

We invite you to comment on legal agreements and a participation plan for two cleanup sites in the Lower Issaquah Valley.

We identified the EFR HQ IVES (Eastside Fire & Rescue Headquarters and Issaquah Valley Elementary School) and Rainier Trail & Memorial Field sites due to releases of per- and poly-fluoroalkyl substances (PFAS) to soil and groundwater. Investigations determined the likely source of PFAS is firefighting foam formerly used at the sites during lawful training activities.

The potentially liable persons for the releases include the City of Issaquah and Eastside Fire & Rescue.

The site documents available for review and comment are:

The agreed orders require the city and EF&R to investigate environmental conditions and complete Remedial Investigations, Feasibility Studies, and draft Cleanup Action Plans.

Learn more at the cleanup site webpages (above) or at an in-person or online public meeting.
