Value of Video Logging

By Christopher S. Johnson, PG, CHg Downhole video cameras lend a tremendous value to water well engineering and rehabilitation, but I believe we can make video logging even more valuable by agreeing on language and procedures to enhance our use of the cameras. So I am proposing some common language and procedures relative to using

Fact and Fallacy

Originally written for the NGWA toolkit By Christopher S. Johnson, PG, CHg Drilling holes in the ground for one purpose or another is easily managed by my grandson— that is, up to a certain depth, in the right soils, above water, with a long shovel, and with the patience of his grandmother. Once we get

Originally written for the NGWA toolkit By Christopher S. Johnson, PG, CHg Boreholes should ideally be both aligned and plumb. Think of a perfectly straight (aligned), perfectly vertical (plumb) line. This is an ideal hole. However, ideal holes are mostly rare, or at the least take effort to achieve. Let’s discuss how we can achieve

Originally written for the NGWA toolkit Many well owners incorrectly believe that wells begin their operational lives at 100 percent efficiency.  In actuality, most wells begin life at less than 15 percent efficiency.  It is through the process of well development, more correctly termed “well efficiency development” that the well efficiency
