Why is this important?

• An abandoned well that is not properly plugged
  could allow contaminants to reach the groundwater
  and could cause a serious risk of someone
  becoming trapped inside
• Each step must be followed to make sure the well
  is properly plugged

Key Steps to Plug an Abandoned Well

1. Measure the dimensions of the well.
2. Remove all obstructions from the well.
3. Disinfect the well by adding household bleach.
4. Remove as much casing as possible.
5. Fill the well with plugging materials.
6. Complete the plugging report.

5
Step One

• Measure the dimensions of the well.
• This information is used to determine the volume
  of material needed to plug the well and the
  quantity of standing water in the well.

Step Two

• Remove all obstructions from the well.
• This will prevent the plugging materials from
  reaching the bottom of the well and having the
  well properly plugged.

Step Five

• Fill the well with plugging materials.
• The plugging materials restrict the mater
  movement from the soil surface to the
  groundwater. These materials need to be clean to
  prevent contamination of the groundwater and
  prevent bridging as the materials enter the well.

Step Six

• Complete the plugging report.
• The plugging report provides documentation that
  the well has been properly plugged. This material
  needs to be sent to the Texas Department of
  Licensing and Regulation and local groundwater
  districts.

23
Importance of Plugging Steps

• Why is each step of the plugging process
  important?

24
Importance of Plugging Steps

• Determine the size of the well.
• Allows accurate estimation of plugging materials
  needed to fill the well and quantity of
  disinfectant for disinfection of standing water.
• Remove debris from the well.
• Prevents plugging materials from bridging, thus
  not allowing the casing to be completely filled.

25
Importance of Plugging Steps

• Disinfect the well by adding household bleach.
• The household bleach will kill any microorganisms
  that have fallen into the well while it was open.
• Remove as much casing as possible.
• Removes the conduit for carrying contaminants
  down to groundwater.

26
Importance of Plugging Steps

• Fill the well with plugging materials.
• Water can not go down through the hole because it
  is filled with slowly permeable material.
• Completing and filing a plugging report.
• Informs regulatory agencies of the properly
  closed well.

27
Who should you contact when considering plugging
a well?

• State and local groundwater districts.
• Licensed well driller in the area.

28
What are some of the common misconceptions when
plugging a well?

• Just dump materials into the well until it is
  full.
• You can fill the well with trash.

Conclusion

• When considering plugging a well, you should
  contact you local groundwater conservation
  district and local licensed well driller.
• Before starting the plugging procedure you should
  have an understanding of the geology of the are
  and the type of well to be plugged.

33
Conclusion

• The six key steps in the well plugging process
• Determine the size of the well.
• Remove debris from the well.
• Disinfect the well.
• Remove as much casing as possible.
• Fill the will with plugging materials.
• Complete and file the state plugging form.
