Some 28 years ago, Dan Stephens left his position as Chairman of the Geosciences Department at New Mexico Institute for Mining and Technology (New Mexico Tech) to apply his expertise in hydrogeology to public and private-sector clients who were facing challenges in complying with tough, new environmental regulations.

“When we first began our business in 1984, the Underground Storage Tank program was really gaining momentum in New Mexico, there was a lot of federal work for nuclear waste siting, and there was a lot of excitement over the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund), the Resource Conservation and Recovery Act (RCRA), and the Toxic Substance Control Act (TSCA),” says Dr. Stephens.

Since then, our growing team of professionals has built on the qualities of expertise, innovation, and tenacity that Stephens brought to his work. We have grown from a small group of hydrogeologists working out of a Socorro, New Mexico, garage to a $20 million corporation with offices in three states. The last few years have seen some of our strongest growth, despite the economic downturn.
