AGI Suggested Reading | Part 1
Posted by Sean on Oct 19, 2018
Welcome to this eight-part series where we’ll be recommending some further reading for those of you who want to learn more about resistivity, induced polarization, and more. We’ve used the publications in this list time and time again—and we want to share that knowledge with you!
This won’t be a definitive list (since there is a lot of great literature out there), but the publications we’ve chosen should help to give you a better understanding of these topics—which can only improve your future geophysical surveys. We’ll be linking to the...

How To Test For Underground Voids (Using Electrical Resistivity Imaging)
Posted by Sean on Aug 16, 2018
In our previous article, The 7 Most Common Signs of Sinkholes, we went over some visual cues to spot sinkholes before total collapse. Now, let’s get a little more hands-on and show you how you can actually test for sinkholes before they occur.
So let’s say you suspect that your site may have an underground void (maybe you see depressions in the ground or cracks in your foundation). If you see any signs of a sinkhole, you’ll have to test the area to see what kind of subsidence or sinkhole you’...
Customer Spotlight: CGS | Legendary Sunken Treasure Found in China With The Help Of Electrical Resistivity Imaging!
Posted by Sean on Jul 19, 2018
Well, it’s not every day that we get to use a headline like that—but it’s true! Last year in China, a customer of ours—China Geological Survey (CGS)—worked with The University of Electronic Science and Technology, and Laurel Technologies for an extraordinary project. The joint research team was tasked to conduct an underwater and shoreline geophysical exploration of the Shen Yin site in Jiangkou after a few artifacts were discovered by locals near the shores of a river. These findings quickly grew into a high-profile...
How to find groundwater using Electrical Resistivity Imaging
Posted by Sean on Jul 03, 2018
So often, after someone asks "What is groundwater?", the next immediete question is "How do I find groundwater?". Well today, we're teaching you the best way we know how to find groundwater—Electrical Resistivity Imaging. First things first, we have to remember where groundwater can be found. As you know from our Groundwater Education Series, an aquifer is a natural underground reservoir of water that can be used as a water source. There are few geological formations in the ground...
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...
