Our Team



Mr. Cobb currently serves as President and Program Manager for AirSource Technologies In this capacity George routinely serves as Project Manager for major RCRA and CPT Trial Burn programs associated with hazardous waste incineration in cement kilns and chemical manufacturing waste disposal. He has directed some twenty trial burn projects typically managing Test Plan preparations, site coordination, analytical support services, report preparations and Quality Assurance review.

George has 35 years of experience in air pollution measurements with emphasis on source sampling. Prior to joining AirSource Technologies in 1990, George enjoyed a seventeen-year association with the Midwest Research Institute, where he was a key participant in dozens of other trial burn programs at various hazardous waste incineration facilities. George also was instrumental in a study to determine safe disposal of pesticides and herbicides by incineration and has investigated the destruction efficiency of microorganisms by incineration techniques.

He was directly involved in the development and evaluation of various sampling trains and methods, and was actively involved in the development of the volatile organic sampling train (VOST) under contract to the EPA.

George has extensive experience with most EPA test methods and has special expertise in determination and speciation of volatile and semi-volatile organic compounds including dioxin/furan compounds, as well as particle size distribution studies.

George received a B.S. in Chemistry with a minor in Biology in 1973 and an M.B.A. in 1980.

Jim came to AirSource Technologies after 15 years at the Midwest Research Institute where he functioned as a Senior Environmental Scientist responsible for managing and conducting assigned emission measurement tasks. Jim brought a wealth of experience with him to AirSource Technologies, including the preparation of proposals, project budgets, work plans, site-specific test plans, quality assurance project plans, and final reports. He evaluated test plans prepared by other contractors for projects to determine the performance of hazardous waste incinerators, municipal waste combustors, and other processes that affect air quality. Jim performed the hands-on preparation and execution of pretest site surveys and emissions sampling and monitoring tasks. He worked with clients in assessing test requirements for regulatory compliance, test protocols for their testing activities, and procedures for implementing emission reduction demonstrations.

Previously, Jim participated in U.S. EPA-sponsored work assignments that involved emission standards development and project-specific quality assurance. Skilled in stationary source testing, continuous emission monitoring, and related quality assurance procedures

Jim’s role with AirSource Technologies is to coordinate the efficient preparation for and conduct of field measurement projects. He is focused on uniformity of equipment and procedural considerations to assure that, every time AirSource Technologies embarks on a test project, all the mechanisms are in place for the effort to be conducted successfully and efficiency.

Prior to joining AirSource Technologies in 2000, Joy spent nearly 24 years working with Midwest Research Institute. Joy specializes in both field and headquarters laboratory support services. Joy has been involved with numerous major field test projects such as Trial Burn, Risk Assessment Burn and Comprehensive Performance Test programs.
