The Matt DeVito Award

The Matthew DeVito award recognizes an individual’s superior ethical conduct and major contributions towards ensuring measurement data quality and representativeness, and the safe implementation of source testing. The procedure the Board established is that an SES member nominates a candidate by letter and includes a justification statement. The nominee does not have to be a SES member. Nominations should describe the nominee and how that person embodies the principles of quality, integrity, safety, and an ethical approach toward stack sampling. Send your detailed nomination for the Matthew S. DeVito Award to the attention of Roy Owens by January 15 of each year.
