Ground Penetrating Radar (GPR) in Lewis County

​​

GPR is commonly used in Lewis County to locate utilities that cannot be detected with traditional locating methods.

Common GPR applications include:

​​

• PVC and clay utility lines
• Septic system (sewer line, tank, leech or drain field)
• Non-conductive utilities without tracer wire
• Buried water and irrigation lines

Results vary by soil conditions and depth, but GPR often provides valuable insight when standard locating is limited.
