[ARCHIVED] Ground Water Sampling Study

The City of Issaquah, in partnership with the Department of Ecology and Eastside Fire and Rescue, will be drilling wells for water sampling and monitoring to inform a pilot study on polyfluoroalkyl substances (PFAS).

The pilot study will allow further investigation of PFAS in soil and groundwater in the lower Is­saquah Valley and will collect additional data that could guide potential clean-up efforts in the future. Issaquah drinking water continues to be safe to drink, as we filter out any PFAS that may enter our water supply.

Drilling times will begin at 8 a.m. in residential areas and be completed by 6 p.m. weekdays. Drilling a well takes approximately 10 hours, and the operation will be noisy at times. We understand that the noise will be an extra inconvenience as most residents are currently home. We apologize—the work must continue in order to comply with state requirements.

Work is scheduled to begin this week and finish in mid-April.

Wells will be drilled at various locations throughout the valley floor:

  • Salmon Run Park near 5th and Juniper (completed)
  • Northwest Holly near Issaquah Creek
  • Issaquah Valley Elementary (parking lot)
  • Northwest Holly near 701 6th Avenue Northwest
  • Memorial Field, near the Senior Center
  • 380 Newport Way Northwest at Northwest Dogwood
  • 200 block of Northwest Alder Court
  • 95 East Dogwood
  • Gilman Boulevard and 4th Avenue Northwest
  • 100 block of Newport Way Northwest

For questions or concerns about the drilling, please contact Cliff Schmitt, Project Manager with Farallon Consulting at 425-295-0801.
