Quantum Geophysics' experienced team provides cost-effective solutions to engineering projects. Since our founding in 1990, we have performed a broad range of successful geophysical investigations throughout the United States.Geophysical methods fall under 2 main streams. In the 1st, naturally occurring phenomena, like gravity, the earth’s magnetism or telluric currents are measured with great accuracy, for values anomalous within general trends will reflect local geological conditions. In the second stream fall methods in which some form of signal is passed into the ground and changes or responses to this signal, resulting from geological conditions, are observed. Seismic and geo-electric techniques are the best known of this group.
