What this license covers
- Drilling / construction: licensed to bore, case, complete, and plug water wells.
- Pump installation: licensed to install, repair, and replace well pumps, pressure tanks, and the piping between the well and the building.
- Cleaning / disinfection: licensed to chlorinate, clean, and redevelop an existing well, the usual response to a bacteria result or a well that has lost yield to buildup.
- Decommissioning: licensed to seal and abandon a well that is out of service; required in most states, since an open well is a direct path for contamination into the aquifer.
