In my last column, I talked at some length about selecting screen openings and then ended up by describing one installation method: just driving a pointed screen into a water-bearing formation. Now, I am aware that in this day and age many screens are either threaded or glued directly to the bottom of the casing in a rotary hole. This certainly works, but if the screen has the wrong openings or fails for some other reason either at installation or later, it is impossible to pull. I’m going to limit my comments to screens that can be pulled and would be used in a cable tool or hollow rod drilled well.
Sue Luft knows first-hand about the problems that occur when a community’s well demands for water far exceed the amount of available water. The Paso Robles, Calif. vineyard owner has faced water shortages due to acutely stressed wells in her area and it has seriously impacted her livelihood.
Chris Preston at Xylem has an official job title of Product Manager, but what he’s really good at is problem solving. As one of the speakers at this year’s National Ground Water Association Groundwater Expo in Nashville, he will be sharing his knowledge about troubleshooting submersible and jet pumps.
As I prepared for the National Ground Water Association’s 2013 Groundwater Expo in Nashville, I wanted to take a look at the state of the industry and offer a few thoughts on its near future.
Drillers know they make an impact, but that doesn’t usually mean helping to supply water for hundreds of thousands of people. Steven Bryan sensed the scope of the Central Utah Water Conservancy District project when he got the call. Working the project, which involves several 24-inch wells that will supply a swath of central Utah, only confirmed the impact.
