How do 1D, 2D, and 3D Resistivity Surveys Compare?
Posted by Sean on Jun 06, 2018
Resistivity surveys come in a few flavors—one-dimensional (1D), two-dimensional (2D), three-dimension (3D), and technically even four-dimensional (4D), though we’ll save 4D for a future post. Let’s focus on 1D, 2D, and 3D for now. If you’re new to the world of Electrical Resistivity, it can be difficult to understand what’s the best type of survey for your needs. In this post, we’ll cover how these three types compare—and the type of survey that we think is the best of the bunch—3D surveys.
First, let’s break down how these different surveys stack up...
How can Groundwater become contaminated?
Posted by Sean on Jun 05, 2018
It’s time again for another entry in our ongoing groundwater series. Today, we’re talking about the more dangerous aspect of groundwater. Specifically, groundwater pollution and contamination. Unfortunately, there are far too many ways for us to cover in one post—but we can always revisit this topic in the future.
So, how does...
The 7 Most Common Signs of Sinkholes
Posted by Sean on Jun 04, 2018
Odds are you’ve probably seen a sinkhole before. If not in person, then on the news—as they tend to make for pretty sensational stories. It’s an exciting, albeit dangerous, natural geological phenomena that happens a lot. The aftermath is hard to miss once it occurs, but there are ways to spot a sinkhole beforehand. In this article, we’re helping you spot the 7 most common signs of sinkholes before they occur. Use these indicators when scoping out the safety of your property—it could help save a lot of risk and money!
Before we get into our...
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...
