John Kastrinos, P.G., LSP

Senior Associate, Hydrogeology

John understands that, when it comes to subsurface investigations, he’s always going to learn something new. He’s passionate about using geology and hydrogeology to better our environment through site characterization, cleanup, and developing alternative energy. 

As a lead hydrogeologist, John takes pride in presenting complex subsurface problems in ways that are easy to understand. He frequently communicates project concepts and approaches to peer groups, clients, regulators, and the public, covering topics from watershed hydrology to the unique geochemistry of commercial-scale ground-source heat exchange (GSHE) systems. 

For more than 30 years, John’s clients have appreciated how his patient, confident demeanor puts people at ease – bringing stakeholders together to make consensus project decisions.
