GTI is a privately held California Corporation, formed in 1987, when we recognized the tremendous need for an honest, innovative service company in the geological and environmental industries. Over the intervening years we have grown into a multidisciplinary firm to meet the challenges of an ever changing environmental industry.

Located in California's Productive Central Valley we service the needs of our Clients from the bay area to the granite mountain peaks and from the seat of government in Sacramento to the oil fields of Bakersfield and beyond.

We have earned a reputation for our ability to combine recognition of our Client's business needs with our understanding of regulatory agency requirements and the behavior of chemicals in the environment. The results are protective and pragmatic solutions to strategic planning, daily and long-range environmental challenges, innovation and maintenance of our Client's projects.

Our Team

We began as a small group of geologists dedicated to bringing the environmental industry top quality, cost effective consulting services. Decades later our staff has grown into a team of qualified and experienced engineers, geologists and hydrologists. In addition, we have ongoing working relationships with a network of environmental professionals and contractors.

We remain dedicated to providing you, our Client, honest, high quality, trustworthy service through all aspects of your environmental needs.
