Quantum Geophysics' non-destructive geophysical surveys can provide cost-effective solutions faster than using conventional methods of data acquisition for environmental projects.

Quantum Geophysics used microgravity to determine the cause of a sinkhole at a retail facility in Harrisburg, Pa. The sinkhole occurred in the portion of the parking lot that overlies the stormwater infiltration basin. Though the area is underlain by carbonate geology, geotechnical drilling that preceded construction showed no signs of sink activity.

The microgravity data showed that the sinkhole lies along the edge of a steeply-sided shallow ridge of rock and that sink activity was most likely triggered by the percolation of stormwater down to and then along the steeply-dipping rock surface. The stormwater acted like a lubricant so that the overlying soils failed under its own weight.

Geophysics does not replace drilling. When used judiciously, geophysics allow you to drill smart by minimizing the number of borings and maximizing the information obtained from them.

Environmental geophysics allow us to locate, identify and/or evaluate:
