Dear readers, I’m writing this in very early January 2013 and although you will read this a little later, I hope you had a prosperous and safe holiday.

Although I have been talking about well casing and drop pipe in several recent columns, I did wander off with some thoughts about conventions of the past last time.

With the 2012 National Ground Water Association (NGWA) Groundwater Expo set for Dec. 4-7 in Las Vegas, I have decided to write a few thoughts about previous NGWA conventions that I have attended.

In my July 2012 column, I wrote about a new-to-me type of PVC drop pipe that has both male and female ends.

A look at welded casing.

"One of the most important parts of a properly constructed water well is the casing, even if bedrock is very near the surface, and collapse of the borehole is not going to happen in that formation."

A few more facts and stories about spudders.

A discussion of a type of drop pipe.

A continuation of the discussion about a 22-W drill rig.
