  2. Overview • Introduce the common methods used to construct wells. • Discuss the different types of wells • Discuss what types of wells a landowner plug. • Discuss reasons for hiring a contractor. • Conclusion

  3. Introduction • There are many different types of well construction methods. • The method used for each well depends on geological formations.

  4. What are the common methods used to construct water wells? • Hand dug • Driven • Drilled

  5. Well Construction Techniques • There are eight different types of well construction techniques.

  6. Land Surface Sealed Rock or Brick Lining as Casing Open Hole Total Depth Type I – Dug Well

  7. Land Surface Casing Cemented Annulus Seal Open Hole Total Depth Type II – Drilled Well

  8. Land Surface Casing Smaller Casing Seal Open Hole Total Depth Type III – Drilled Well Cemented Annulus

  9. Land Surface Casing Cemented Annulus Seal Gravel or Sand Pack Casing with Selected, Perforated, Slotted, or Screened Intervals Total Depth Type IV – Drilled Well

  10. Land Surface Casing Cemented Annulus Seal Gravel or Sand Pack Casing with Selected, Perforated, Slotted, or Screened Intervals Seal Open Hole Total Depth Type V – Drilled Well

  11. Land Surface Large Casing Cemented Annulus Smaller Casing with Selected, Perforated, Slotted, or Screened Intervals Total Depth Type VI – Drilled Well

  12. Land Surface Casing Cemented Annulus Seal Gravel or Sand Pack Seal Casing with Selected, Perforated, Slotted, or Screened Intervals Total Depth Type VII – Drilled Well

  13. Land Surface Casing Gravel or Sand Pack Casing with Selected, Perforated, Slotted, or Screened intervals Total Depth Type VIII – Drilled Well

  14. What type wells can a landowner plug? • A landowner can plug type I-V wells, assuming there is less than 100 feet of standing water in the well.

  15. 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.

  16. 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
