This one of a series of handbooks is specifically designed to meet the Partners for Environmental Technology Education (PETE) curriculum guidelines now established for the introductory course in the Environmental Hazardous Materials Technology (EHMT) Associates Degree Program. Volume IV is a serious “how-to” handbook covering both theory in the development of a sampling plan and definitive concepts in obtaining a representative sample. It provides an overview of environmental and hazardous materials protocols and procedures with emphasis placed on documentation.
