Module 9 — Plugging Abandoned Wells
Special Problems
Flowing wells present special problems for plugging. It is highly recommended that you
use the services of a licensed water well contractor. Before a flowing well can be plugged, the
flow must be controlled. Several methods can be used:
Reduce the flow by pumping high specific gravity fluids such as drilling mud or cement
into the well.
If there is a nearby well that is tapped into the same aquifer as the flowing well being
plugged, pump it to create a drawdown in the well being plugged.
Where practical, extend the well casing high enough above the ground surface to stop
the flow.
Worksheet
For future reference, use the "Record of Well
Plugging" worksheet to record the date of
plugging, materials and procedures used.
Also map the location of this plugged well for
future reference. A sample copy is included
at the back of this module. Working copies
are included in the pocket on the back cover.
Keep the worksheet in the back pocket.
