iMAP Map Set: Groundwater Program

Abstract

This map set provides information about groundwater and water supply in King County, as maintained by the Groundwater Program of the Water & Land Resources Division.

Possible Uses

  • Find out who supplies drinking water to a particular area in the county (view Water Service Areas).
  • Learn how groundwater contamination travels through different types of soil at different rates (view Wellhead Protection Areas).
  • Identify areas where groundwater is close to the surface beneath permeable ground layers, such as sand or gravel (view High Groundwater Contamination Risk).
  • See where plans are being developed to protect groundwater (view Groundwater Management Areas).
