Before you sign a contract with a geophyscial service provider, there are some general considerations for the site conditions you need to discuss with them for cost-effective and successful geophysical surveys.

  1. Is the site generally accessible through vehicles or ATVs? Geophysical equipment for some tasks could be heavy and vehicle access could speed up the data acquisition process significantly. Sometimes the data acquisition design/logistics could be totally different depending on the easiness of vehicle access.

  2. Is the site generally walkable? Is it heavily ve...

We’re frequenctly requested by clients to bring “concrete GPR” to sites for searching something underground. However, sometimes these requests were based on the misconception of concrete GPR. Just because the medium is concrete it does not mean that the "concrete GPR” is the best approach.

The main difference between a concrete GPR and a regular GPR, such as those for underground utility locating and underground storage tank locating, is the antenna frequency. The antenna frequency of a concrete GPR system is usually in the range of GHz, while those of regular GPRs are t...

Enviroprobe conducted an underground utility locating survey at a gas station in Morristown, NJ. During the process of searching for underground utilities, an anomaly showed up in the ground penetrating radar data close to the pump island. The experienced Enviroprobe geophysicist immediately realized this could be an orphaned underground storage tank. Further investigation utilizing metal detectors confirmed the finding. The finding was notified to the client, a reputable environmental consulting company, so further appropriate actions could be taken.

Prior to drilling, digging, trenching, and excavating, it is essential to know where underground utility lines are located. It’s particularly important for gas stations. Unlike residential house and office building properties, gas stations usually contain extra underground utilities including those for gasoline/diesel tanks and pumping systems. Besides the usual utilities including electrical power, communication, sewer, water and natural gas lines, there are other important lines such as fuel/product lines, ventilation lines and electrical conduits for the gasoline/die...
