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.

Variance - Problems and Solutions - A variance is written permission to use
a pre-approved alternative method of well construction. The most common types of
variances requested are for locating an individual domestic well closer than
100 feet from a septic system,
drainfield, or any potential source of contamination.
Protection Wells: Frequently Asked Questions
Seals - Problems and Solutions - This pamphlet educates the public about the
importance of proper surface seals on wells. Well drillers use casing,
typically steel, to keep drilled holes from collapsing. If just the native
materials are allowed to fill in around the casing, a conduit for water can form
on the outside of the casing, so that dirty water can travel down the casing and
into your well. To prevent this, a surface seal is used.

Tagging Requirements - Licensed drillers in the State of Washington are
required to tag all new or reconstructed wells.
Wells Caps -
Problems and Solutions - The purpose of this pamphlet is to educate the
public about proper installation of well caps. Wells that are not in use,
or will be temporarily out of service, are required to be securely capped so
that contamination can not enter the well (WAC 173-160-085). Well capping is one
aspect of this state's well construction standards that Ecology's inspectors
look for, and something that homeowners and drillers alike should take
seriously. A proper well cap will help ensure the users are safe and is
instrumental in making sure that contamination doesn't enter a well from the

Well operators have been required to obtain continuing education since
1998. Mandatory continuing education allows
drillers to stay informed of industry changes and technological advances. It
also allows for networking among the drilling industry professionals where
ideas, concerns and issues are raised and resolved.
Drillers must send proof of continuing education at the time of
application for a new license or renewal of an existing license to Ecology.
For a new license, please read the
Guide to Water Operator License Program for specific dates to send
proof of continuing education. If you are currently licensed, check
your drilling license for the date of expiration. You must send proof
of continuing education prior to this date.
For more specific details on continuing education please read
of Licensed Well Operators.
Mail your proof of continuing education to:
