Ed Squires, President of Hydro logic Inc., a hydrogeological consulting firm in Boise, Idaho, is an avid promoter of PVC well casing for large-bore wells in a state that has been slow to embrace the use of PVC for that application.
Steel well casings remain the standard with drilling contractors throughout Idaho, owing to the fact that more than 80% of drilled wells are drill-and-drive air rotary domestic wells.
Another impediment to the use of PVC casing is a rule requiring drilling contractors to first apply for a waiver from the state government allowing them to use PVC. Although the waiver rule is more geared toward ensuring that drillers who use PVC casing do not use a low-grade PVC, it still creates yet another regulatory requirement for the contractor.
However, a change may not be too far down the road. Squires and other drilling professionals are currently working with state ground water agencies to promote the benefits of using PVC well casing and the open-hole drilling methods that facilitate its use. By doing this, they hope to give well owners and drillers more incentive to use PVC. Water Well Journal, March 2007.
