Customer Spotlight: 4africa | Finding Groundwater in South Sudan
Posted by Sean on May 11, 2018
In our ongoing educational series, What you need to know about Groundwater, we mentioned some organizations that help provide drinkable groundwater to areas that are desperate for it. In this post, we wanted to focus on one of those organizations—and a previous customer of ours—4africa (Previously East African Ministries/Radler Foundation).
“4africa is a humanitarian organization based in Fort Worth, Texas that focuses on water, health, and leadership...
[INFOGRAPHIC] Groundwater Use in the U.S.
Posted by Sean on Apr 23, 2018
We’ve covered a lot so far in our groundwater educational series (But really, we’re just getting started!). Today, we want to take a closer look at The United States’ use of groundwater. Check out the infographic below to see a few ways we use groundwater in the U.S.
All data used in the infographic was sourced from The National Groundwater Association

The Benefits of a Weak Dollar
Posted by hasan on Feb 27, 2018
Let’s face it, no one wants to hear that their currency is weak—especially Americans who may not want to hear that, as of right now, the US dollar is weak and the Euro is on top. But what if we told you that having a weak dollar was a good thing—not just for Europeans, but for American businesses as well? Ok,...
Pole-Pole Array: Electrical Resistivity Methods, Part 5
Posted by hasan on Oct 06, 2017
Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier.
Today, we’re discussing the pole-pole electrode configuration—this is the fifth article in our series exploring 11 electrode arrays and methods. We’ve also covered the following:

Schlumberger Array: Electrical Resistivity Methods, Part 2
Posted by hasan on Oct 06, 2017
Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier.
This is the second article in our series exploring 11 electrode arrays and methods. We’ve also covered the Wenner array. Today, we’re discussing the Schlumberger array.
What is the Schlumberger array?
The Schlumberger array is an array where four electrodes are placed in line around a...
Wenner Array: Electrical Resistivity Methods, Part 1
Posted by hasan on Oct 06, 2017
Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier. In this series, we’ll explore 11 electrode arrays. The first array we’ll discuss is the Wenner array.
What is the Wenner array?
The Wenner electrode array is the simplest of arrays; in it, the four electrodes—A, M, N, and B—are placed in line and spaced equidistant from each other. The two outer electrodes, A and B, are current electrodes,...
The Streaming-Potential Method: Its 2 Main Uses
Posted by markus on Feb 28, 2017
Streaming-potential (SP) is an electrical surveying method used when fluids or electrolytes—typically water—move through porous areas in the ground. This creates a change in voltage that can be read using a voltmeter and two electrodes. Streaming-potential is synonymous with “self-potential” and “spontaneous-potential,” though the latter two designations are used when the cause of the spontaneous voltage is chemical processes associated...
An Overview Of The Self-Potential (Spontaneous-Potential) Method
Posted by markus on Feb 15, 2017
Before we dive into details, let’s start with a primer on three different terms that are abbreviated “SP.” In this article, we’ll be discussing self-potential, which is synonymous with spontaneous-potential. The self-potential method in geophysics refers to an electrical surveying method used for looking at electrical anomalies in the ground. It is primarily used in mineral exploration. Streaming-potential, on the other hand, is caused by a fluid —typically water with dissolved minerals (an electrolyte)—moving in the ground, which causes a change in voltage. This change is detected when a...
