Even with a type I-V well, why might it be better to hire a
contractor?• A contractor may have better equipment
and understanding of the geology conditions that affect how the well should be plugged.

Conclusion
• Landowners have the authority to plug type I-V wells if there is less than 100 feet of water in the well.
• Only licensed well drillers should plug type VI-VIII wells.
• In some cases it may be better to hire a contractor for type I-V wells
