QuanTech, Inc. Environmental Sciences

The Environmental Sciences Technical Group

Most of the current activities within the Environmental Sciences Group are related to support of Lead-Based Paint (LBP) research activities. QuanTech has been involved in LBP work for EPA and HUD since the founding of the firm. The Environmental Sciences Group is managed by Dr. Gary Dewalt, who is active in the environmental testing industry. Dr. Dewalt served as project leader for most QuanTech lead-based paint studies involving field and chemical analysis activities, and was the task leader for field and laboratory portions of the EPA/HUD field study: Field Test of Lead-Based Paint Testing Technologies. This study, a joint effort conducted by QuanTech and Midwest Research Institute, was designed by Dr. David Cox, the President of QuanTech. Dr. Cox was also the author of Chapter 4, "Testing for Lead-Based Paint", in the 1990 HUD Guidelines, and of EPA's Model Lead Inspector Course published in 1993.

The Environmental Sciences Group is currently involved in designing and conducting follow-on activities to the Field Test of Lead-Based Paint Testing Technologies, including operation of a testing archive formed from samples collected in the field study. This testing archive is being used to Develop Performance Characteristic Sheets (PCSs) for XRF testing as directed by the 1995 HUD Guidelines.

The Environmental Sciences Group is also active in the design and development of paint film standards for the National Lead Abatement Council (NLAC) in support of the National XRF Operators Registry through a grant funded from the Department of Housing and Urban Development.

The Environmental Sciences Group produces leaded film standards for XRF and Test Kit applications. The groups project activities have included the development and operations of The Lead Listing.
