Locating Underground Storage Tanks In Hot Springs, Arizona

Ground Penetrating Radar Systems was recently contacted by a general contractor to locate and mark out all underground storage tanks, underground utilities, as well any underground anomalies at their site in Hot Springs, AR prior to soil boring.

GPRS used the latest ground penetrating technology to provide relevant information about critical utilities and other potentially dangerous, and problematic areas underground while on site.

The equipment used in the survey was:

  • GSSI Ground Penetrating Radar/ SIR 3000 – This device transmits a signal into the ground that sends data back in real time.

    • 400 MHz antenna – This antenna allows for GPR signal penetration 4’-8’ through the ground.

  • RD-7000 locator – This device detects live power and RF signals underground, allowing us to locate electrical or telephone lines even if they are below the minimum size requirements to be detected by GPR. It also allows us to detect utilities via induction or conduction with an exposed or known surface of the conductive utility.

While on site, GPRS technician Ethan King, scanned approximately 1 acre around the gas station to identify any anomalies that would indicate UST’s, electrical conduits, gas lines, and any other pertinent utilities moving through the customer’s anticipated excavating locations. After further investigation at the suspected site GPRS was able to determine that there were 3 UST’s (approximately 4’-4.5’ in depth), electrical conduits (approximately 1’-2’ in depth) and product piping (approximately 3’-4’ in depth) running from the UST’s to the fueling stations. Gas, electrical running to light poles, signs and building were also all detected using GPR. GPRS plotted the locations of subsurface obstructions directly onto the surface, and provided accurate depths giving the contractor a clear indication of where it was safe to drill, as well as where extra caution would be necessary.

Not only did GPRS ensure the safety of the crew by identifying potential life threatening hazards, but also eliminated any potential costly repairs that may have been added to their project due to damaging unknown utilities.
