GPR For Environmental Assessment – Cutting The Cost Of Investigation

The cost of an environmental assessment can be staggering. It is an added cost for your project. Using GPR for environmental assessment can help reduce the cost, eliminating the need for more intrusive research.

How Does GPR Help In Environmental Assessments?

Ground penetrating radar allows us to get a picture of what is happening underneath the ground before digging begins. GPR can help determine if there is solid structures, water, or other issues lying underground that could cause issues when you begin excavation and construction.

GPR makes it easy to pinpoint areas on your project site where more extensive testing and research is required. This may sound like the opposite of what you were hoping, but it is not. It prevents the entire site from being assessed intensively and allows the assessment team to focus on important areas, instead of the entire site.

Cutting Costs By Avoiding Trouble Spots

GPR gives you another way to cut costs, too. When using GPR for environmental assessment, you can keep a map of the entire site showing where hidden pipes, electrical lines, underground storage tanks, and other obstacles lie.

This allows you to either avoid the obstacles completely or to plan your excavations precisely for their removal. Instead of cutting through a pipe accidentally, you know exactly where it is and can work around it. This saves both time and money.

Reducing Hazards For Employees

Ground penetrating radar lets you determine quickly if there are potential toxic materials lying underground. This allows you to make a remediation plan for removing the toxic items cautiously, instead of an employee stumbling into the mess and getting injured.

The maps provided by GPR makes sure your excavation team does not cut into dangerous electrical lines, gas pipes, or other hidden dangers. This reduces your costs by eliminating injuries.

Depth and Location

It is not enough to know where a pipe or toxic material spill is located. You need to know how deep it is, too. 3D GPR mapping can give you a clear picture of how deep you will need to dig to remove the problem, or how deep you can dig and avoid an obstacle.

This is critical information for contractors. They can carefully flag a building site, identifying the location and use color coding to inform employees of the depth of potential hazards.

Planning Your GPR Assessment

Using GPR is not a haphazard process. It must be carefully planned and executed. The GPR equipment must cover every inch of land your assessment covers. If you miss areas, your maps and assessment will be inaccurate and could leave dangers unidentified.

In most cases, you will want to work with a professional assessment company who specializes in using GPR for your environmental study. They know how to get precise maps of your build site to make sure all potential hazards and problems are identified. Their team can read the maps and help interpret the results eliminating the guesswork.


GPR is no longer a luxury when conducting environmental assessments. It is a way to attain more accurate mapping while cutting costs. Check with your environmental assessment team if they plan to use GPR on your site.
