You may be able to drill a well... but can you use the water?

Many basins do not have enough water for new wells and may be closed to further withdrawal of groundwater.  A closure in your area may prohibit withdrawal even from permit-exempt wells.  You must determine whether the basin where you intend to withdraw water is open to withdrawals.  More information can be found by reading the Water Availability Focus Sheets at:

Notice of Intent (NOI) to Drill a Well
  • The Notice of Intent is not a permit, certificate, or application for a water right. 
  • Your Notice of Intent does not represent approval or permission to use water from the well. 
  • Once the well is drilled, the water may only be withdrawn if it is legally available and then NEEDS TO BE put to beneficial use to establish a "right" to use of the water.

Decommissioning of Abandoned Wells

Decommissioning of Abandoned Wells - It is not uncommon in Washington state to find old wells which are no longer usable.  These are called abandoned wells. The most common type of abandoned well is the shallow dug type.  Abandoned wells can pose safety and environmental problems, and are required to be properly decommissioned as soon as possible after use stops.  Closing down an old well is called decommissioning.

Information for Well Drillers

Information for licensed well drillers, including- well construction, decommissioning a well, licensing, and continuing education.

How do I send a well report to Ecology?

  • All well reports should be mailed to the regional office servicing that county.  You can use the Ecology Directory to find the mailing address for the appropriate regional office.
  • Well Report Gateway – for "Geotechnical Soil Borings and Environmental Investigation Wells”
