Written in plain language, this manual draws on examples that are relevant to the widest possible audience. Experience has shown that students retain and understand information better when instruction is personalised and when explanations are provided as to why a procedure exists rather than the procedure simply being cited.
The manual is intended for easy reference in both teaching and practical situations. It contains “discussion” sections that are designed to stimulate group reflection and debate. Significant concepts are identified in bold or italics. The techniques described are typically used by investigators and inspectors, although this does not mean that they are the only acceptable methods. The aim is to help inspectors establish a sound foundation and adapt their own style.
The manual was written by the United States Environmental Protection Agency.
