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.

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.

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!    

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).   

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

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:
