Well Abandonment Information

  • Old wells that are left open and/or unused are at risk of having contaminants enter into them and into the groundwater.  
  • Old drilled wells can develop cracks in the steel casing that can let contaminants through.  
  • Old dug wells were often lined with brick or field stone which does not provide a good barrier to prevent contaminants from reaching groundwater.  
  • Once contaminants reach the groundwater, it is difficult, if not impossible to remove them.  
  • Often the contamination will migrate to other wells drawing water from that aquifer.  
  • Old and unused wells may also pose a safety hazard.  
  • Old dug wells can be 6 feet across and 50 feet deep or deeper.  
  • Serious injury or worse could result if a person or animal fell into an old well.
