💧 Ask a Geologist: How Do Geologists Determine the Best Location for a Water Well?

Where you drill can have a major impact on how a water well performs.

Geologists use multiple sources of information to evaluate a site before drilling begins, including:

• Site geology
• LiDAR and aerial imagery
• Electromagnetic mapping
• Electrical resistivity surveys

Together, these tools can help identify fractures, weathered zones, and other subsurface features that may indicate more promising areas for groundwater.

In our latest Ask a Geologist blog, we break down the 5-step process used to help identify potential well locations and reduce some of the uncertainty associated with drilling.

Removing an old underground heating oil tank is only one part of the process.

For a recent project, soil sampling identified evidence of a petroleum release around an out-of-use underground heating oil tank.

Once the tank was excavated, significant corrosion and multiple holes were found, along with petroleum-stained soil and a noticeable petroleum odor beneath and around the tank.

HydroGeo Environmental removed the tank and approximately 4 tons of petroleum-impacted soil.

Soil samples collected during and after excavation helped determine which material was impacted and evaluate the soil left in place after cleanup.

Why does that matter?

Because removing the tank doesn’t automatically mean the environmental concern is gone. Soil sampling helps show what may have leaked into the ground and whether additional cleanup or investigation is needed.

That data helps property owners better understand what’s happening below the surface and make informed decisions about next steps.

Electrical resistivity gives geologists another way to see what traditional observation can’t. Electrical Resistivity Imaging (ERI) gives geologists a way to better understand subsurface conditions without relying solely on what can be seen at ground level.

By measuring how strongly underground materials resist electrical current, ERI can help identify changes in soil, bedrock, moisture conditions, and potential fracture zones.

Lower resistivity values may be associated with wetter soils, clay-rich materials, or water-bearing features, while higher resistivity values are often associated with drier materials or competent bedrock.

The result? Better subsurface data to support more informed decisions for projects involving groundwater, well siting, environmental investigations, and geotechnical evaluation.

What’s below the surface can make all the difference when planning a water well.

Choosing a well location shouldn’t be a guessing game.

Before drilling begins, HydroGeo Environmental uses advanced geophysical methods to better understand subsurface conditions and identify areas that may have greater potential for groundwater.

For a recent groundwater availability assessment, our team combined:

🔹 Fracture trace analysis
🔹 LiDAR data and aerial imagery
🔹 Electrical resistivity (ER) imaging

In fractured bedrock areas, groundwater often moves through fractures, joints, and weathered zones within the rock. Understanding these features can provide valuable information before a drilling location is selected.

During this assessment, geophysical surveying helped identify subsurface features and provided additional data to support well siting decisions.

While no investigation can guarantee water production, using science-based methods before drilling can help reduce uncertainty and provide a more informed path forward.

💧 Better Well Siting Starts With Understanding What’s Below the Surface

Drilling a water well doesn’t have to be a shot in the dark.

For a recent groundwater availability assessment, HydroGeo Environmental combined fracture trace analysis, electromagnetic (EM) mapping, and electrical resistivity (ER) imaging to evaluate subsurface conditions and identify promising areas for well placement.

Because groundwater in fractured bedrock is often stored and transmitted through fractures, joints, and weathered zones, the location of a well can have a major impact on its performance. Geophysical surveys help identify subsurface anomalies that may indicate increased fracturing and potential water-bearing zones—providing valuable information before drilling begins.

By combining multiple datasets, our team can help clients make more informed well-siting decisions and reduce some of the uncertainty associated with randomly selecting a drilling location.

Virginia realtors: hidden property issues can make buyers hesitate, especially in a cautious market.

Before inspection day creates a problem, help your sellers get ahead of potential concerns below the surface.

HydroGeo Environmental helps realtors identify issues such as:

✅ Buried tank risks
✅ Well and groundwater concerns
✅ Subsurface site conditions

With clear data and straightforward recommendations, HydroGeo helps support stronger seller preparation, reduce inspection surprises, and give buyers more confidence before closing.

Help your clients move forward with confidence.

💧 Three wells had already been drilled—but the property still did not have an adequate water supply.

Rather than choosing another drilling location at random, HydroGeo Environmental completed a groundwater assessment to better understand the conditions below the surface.

In fractured bedrock areas, groundwater moves through cracks, joints, and weathered zones in the rock. These features can vary greatly across the same property, which means one location may produce very little water while another nearby area may offer better potential.

Our team used:

✔ LiDAR and fracture trace analysis
✔ Satellite imagery and geologic mapping
✔ Soil and bedrock information
✔ Electrical resistivity imaging

The investigation identified a fracture-like subsurface feature that may provide a more favorable target for future well drilling.

While no groundwater investigation can guarantee a specific well yield, using geologic data and geophysical testing can help reduce uncertainty and support a more informed drilling decision.

Before drilling again, take a closer look at what may be happening below the surface.

Ground Penetrating Radar can be a valuable tool, but it does not work the same way in every type of soil.

Soil type, moisture, depth, target material and overall site conditions can all affect how clearly GPR identifies what may be below the surface. Dry, sandy soils often allow signals to travel deeper, while wet or clay-rich soils can reduce signal pe*******on and make targets harder to detect.

That is why choosing the right geophysical method starts with understanding the site.

At HydroGeo Environmental, we evaluate the project goals and subsurface conditions before recommending the most effective approach. Sometimes GPR is the best option. In other cases, another method or a combination of methods may provide better information.

The right equipment, site knowledge and professional interpretation can make all the difference.
