Many of the ideas for my column are inspired by questions I get from readers and friends in the industry. A few weeks ago, someone asked how to wire in a pressure switch with a pump protection device that required a control relay.

Lots of people talk. Few people act. Oregon State University Professor Michael Campana easily fits into the latter group. The Driller spoke with Campana about his “H20 Talk” at this month’s National Ground Water Association 2013 Groundwater Expo in Nashville, Tenn. His talk, “Hydrophilanthropy: What can you do?,” discusses his efforts bringing water systems to those in need in Central America, and what groundwater professionals can do to make a difference.
The National Ground Water Association announced this year’s crop of award recipients. Awardees formally accept their awards at the 2013 Groundwater Expo in Nashville this month. This year’s awards recognize a variety of groundwater professionals and projects.
I was contracted to fly to California as an expert witness for an attorney who was suing a well contractor because the well casing had been damaged due to an attempt to drive a dropped pump in the well.

And, finally, we will go over the proper placement of check valves in these systems.
