The goal of the Drinking Water Program is to ensure that Thurston County residents have a safe supply of drinking water. This is done by:

  • Reviewing water system plans for small water systems (WA Dept of Health reviews large systems).
  • Inspecting sites for proposed drinking water wells to ensure that they are located away from sources of potential contamination.
  • Ensuring that building sites have an approved source of drinking water available before issuing building site approvals.
  • Reviewing water quality monitoring data from small water systems (DOH monitors large systems).
