GSi/water, Inc.

Geothermal Surveys, Inc. (dba GSi/water) was established in the early 1960s. The company specializes in the exploration and production of ground water resources and related applications. The technical member of our company are geologists, geophysicists and ground water hydrologists.

Our services encompass a broad spectrum including development of ground water as a resource, leakage identification in dams and other impoundments, and identification and monitoring of moving fluids. We work domestically and abroad.

We utilize programs of integrated geology, geophysics and hydrology to identify the best possible well locations for our clients. We design and oversee the processes of drilling, construction, and testing of wells as part of services.

We use various geophysical techniques to help us solve complex ground water problems. One of these techniques, the use of shallow ground temperatures to identify and trace the movement of underground fluids, was developed and pioneered by our company and was the basis on which the company was founded.
