GTI has more than 21 years of experience in evaluation of the geologic and hydrologic processes. We have worked on the interactions of a broad spectrum of contaminants in the soil and groundwater and have designed and implemented remedial alternatives appropriate for many varied sites.

GTI helps meet the needs of California's water supply demands by offering groundwater resource evaluation studies for community and commercial development projects. These studies assess the local geology and groundwater hydrology in the context of the regional geologic setting.

GTI helps small community water producers evaluate their drinking water and possible aquifer contaminants that can degrade its quality to find solutions to these drinking water contaminant problems.
