In Situ Access to Contaminants

who we are

Management
With nearly 25 years experience performing and managing environmental services,  Doug Knight has overall responsibility for day-to-day operation of the company.  With his long experience at FRx and close affiliation with the founders, he is well versed in underlying technical theories as well as mechanical and logistical aspects of performing fieldwork.  He also has a unique knack of being able to quickly identify an optimal injection program for a new site.  Although Doug has trained a dedicated staff of technicians to perform field work in accordance with the most prudent theory and methods, he often attends and supervises field work.
