Introduction to the Air & Waste Management Association's 30th Annual Critical Review

This marks the 30th year of the Air & Waste Management Association's Critical Review Program. The Critical Review is a feature of A&WMA's Annual Conference, and is directed by the Critical Review Committee. The committee evaluates several topics each year, selects the best for presentation, and invites an individual (or group) to prepare the Critical Review Paper. This paper is thoroughly reviewed by the committee members and a panel of experts. After presentation of the review by the authors (typically on the Wednesday of the Annual Conference), there is a panel discussion and question-and-answer session. Panel members are invited to prepare their comments on the Critical Review, which, along with audience comments and the author's closing statements, are published in the Journal.
