Scott Underhill, P.E.

Senior Technical Specialist

Scott’s passion for water and learning inspired him to become an environmental engineer. With over 25 years of experience, his diverse background includes the investigation, design, installation, and operation of remediation systems for soil, water, and air; design of water and wastewater treatment facilities; energy studies; and numerical modeling of environmental media. Scott is motivated by his personal relationships to go above and beyond for federal, state, and industrial clients throughout the U.S. Most recently, he has worked on the remediation of contaminated sites, such as manufactured gas plants (MGPs) and chlorinated solvent sites, in the Northeast and Midwest.

Clients and colleagues value Scott’s mentorship and how he applies his professional experience to improve communities. He’s an active member of Engineers Without Borders, serving as a mentor to the student chapters of Rensselaer Polytechnic Institute and Purdue University.
