This book is a compilation of the papers presented at the Twenty-Ninth Mid-Atlantic Industrial and Hazardous Waste Conference. It helps people to move a step closer to the acceptable balance of costs, benefits, and risks in their attempts to resolve industrial and hazardous waste problems.Session 1: Biological Treatment 1.
