This guide is designed to help those involved in site investigations to determine the amount and extent of soil contamination and potential for movement of contaminants in the soil and groundwater. It contains checklists, tables and step-by-step descriptions of methods and procedures for: cost-effective, detailed site investigations for evaluating the potential for contaminant transport; and field collection of information on soil engineering properties required for remediation selection and design. The text also features an adaptation of soil description procedures used by the US Soil Conservation Service (SCS) for investigating contaminated sites. The SCS soil description and classification procedures are useful for evaluating the potential for contaminant research.
This edition contains additions to sections describing soil features, new tables with expanded criteria for placement of soils in hydrological groups and on colour and occurrence of iron oxide minerals, summary tables on hand-held and power-driven soil sampling equipment, a new appendix on SCS's approach to the descriptions and interpretation of aquatic soil conditions, and a new appendix with checklists that identify the availability of field, laboratory and estimation procedures for more than 100 site soil and contaminant physical, chemical and biological parameters.
