If you have perforated casing and the formation no longer produces enough, you must seal the open perforation with cement before you drill down to the next aquifer.
A friend called the other night to catch up and chew the fat about things in general. I asked him if he was busy, etc., and he told me that he had lost a well that day.
Any kind of water is treatable. However, there are times when it makes more sense to repair potential issues with a well, and other times that call for drilling a well in a new location.
A while back, I wrote about gravel packs and well development, but I have had several calls and emails about wells that wouldn’t clear during development.
The USGS and CDC National Center for Environmental Health study suggests 2.1 million Americans using household well water could be at risk of harmful arsenic exposure.
As I think back, it seems I encountered more problems with pumps and water conditioners than with wells I drilled. I also remember that many of the difficult jobs were due to the attitudes of my customers.
All too often, Michael Schnieders, PG, PH-GW, sees water well drillers go into projects assuming that a problem well should be diagnosed and treated the same as other problem wells they’ve worked on. That isn’t the case, though.
