Stephen W. Kirschner, P.E., RSM
Senior Project Consultant in the Environmental Services group
Mr. Kirschner has 30+ years of experience in the investigation and remediation of various organic and inorganic compounds. He has extensive experience with in-situ and ex-situ groundwater remedial design, soil stabilization/management design, vapor intrusion assessment, and the optimization of remedial systems. Technologies include soil vapor extraction, air sparging, groundwater extraction, thermal treatment, bioremediation, and ozone sparging. He currently chairs Montrose Environmental’s Emerging Contaminants Team (MECT). Mr. Kirschner is a licensed Professional Engineer in 11 states. MECT combines Montrose’s broad expertise in soil, air, water, groundwater and sediment testing and evaluation of emerging contaminants and particularly per- and polyfluorinated alkyl substances (PFAS). Mr. Kirschner is also the technical lead for the investigation of a PFAS release that has impacted the drinking water supply of a city in New York. Mr. Kirschner is a professional engineer licensed in 11 states. He has participated in PFAS training seminars and workshops by the National Ground Water Association, the American Bar Association and various regulatory agencies. Mr. Kirschner also has extensive third-party stakeholder engagement and has participated in multiple public meetings.
