Welcome to the “In Search of Water” blog site! Here you will see the chronicled events of the project leading up to the team’s departure from the United States and then daily while the team is in Africa. Feel free to comment on the posts as it is a great encouragement to the team and a great way to share in the experience together.

Using the Resistivity Meter to find the water

On Sunday, the drill rig did not show. On Monday mid day the first drill vehicle came but it was not the drill rig, it was the crew to determine where to drill. They start off with the old witching method of taking a copper rod in each hand and walking until the rods cross each other. This is the location of water. Then he sets up his resistivity meter with an electrical wire spanning 100 meters to get a resistance reading of the ground at various points along the 100 meters.

The first spot had solid rock at 30 meters and was not good for drilling. We had to move 1/2 mile closer to Aaron's compound to find a good drilling spot. This one had water starting at 30 meters and continuing to 70 meters, a great location. This would be the new borehole spot.
