these web pages are currently underway. For more information,
In partnership with delegated counties, Ecology protects and assists consumers, well drillers and the environment by:

Water availability for wells
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.
Submit a Notice of Intent before you drill
Before drilling a well, you must submit a notice of intent (NOI) to the Department of Ecology. This document needs to be submitted to Ecology 72 hours before the well is drilled.
An NOI is not a permit, certificate or application for a water right nor does it represent approval or permission to use water from the well. Once your well is drilled, water may only be withdrawn if it is legally available. The well also needs to be put to beneficial use to establish a ‘right’ to use the water.
Send Ecology a well report (well log)
A well report (well log) is a detailed record of the geological formation during the drilling of a well. The report (well log) also contains the location, owner name, driller name and well water production. This document is required to be submitted to us 30 days after the well is completed.
Well reports are mailed to the nearest Ecology regional office servicing that particular county.
Resource protection wells are drilled for monitoring and sampling. Most of these wells are temporary. The reports document the construction and location of the wells. Resource protection well reports can be submitted electronically using the Well Report Gateway.
Decommissioning abandoned wells
Washington state law requires property owners to properly decommission (or close down) wells that are no longer usable. See Decommissioning of abandoned wells for more information.
