We believe that employee performance and improvement is possible through continuous training and exposure to new technologies. It is mandatory for each scientist and engineer to complete five to seven hours of continuing education (CE) training each year through specialty courses offered by the US EPA, Indiana Department of Environmental Management or other approved agencies.
Our team strives for excellence through Total Quality Management (TQM). Our procedures, processes, and methods of operation undergo a thorough review by our QA/QC Director on a project-by-project basis.
