Key Personnel

BAI’s approach to projects consists of a team effort between our environmental scientists, engineers, geologists, hydrogeologists, technicians, and support staff. The individual project team leader is generally selected on the basis of type and complexity of the project and whether it is in the investigation, design, or construction phase. Biographical Sketches of key personnel follow. Full resumes are available upon request.
