This document gives general guidance on the development of site investigation strategies and detailed guidance on the development of sampling strategies, when collecting information on It is applicable to soil samples intended for chemical testing and determination of a variety of other properties (e.g. physical). Although the main focus of this document is the collection of material (field samples) for transfer to a laboratory for testing, it is also applicable when measurements are made directly in the field.
