Description:
The document serves as a companion document to the Soil Sampling Quality Assurance User's Guide, Second Edition. he two documents together provide methods, techniques, and procedures for designing a variety of soil measurement programs and associated Quality Assurance Program Plans, implementing those programs and then analyzing, interpreting, and presenting resultant data. roperly designed sampling plans based upon the laws of probability provide a means of making decisions that have a sound and defensible basis. his document summarizes various statistical and geostatistical concepts and procedures pertaining to the design, implementation, and data interpretation of appropriate sampling designs. oo little time is usually spent in preliminary data collection, valuation nd lanning. ithout reviewing existing data and developing a conceptual model of the pollutant behavior at the site, it is difficult to undertake a reliable soils study. oil sampling takes place either in the surface layer (0-6 in.) or at greater depths. he methods of sampling each may be different but make use of two basic techniques. amples can either be collected with some form of core sampling or auger device, or they may be collected by use of excavations or trenches.
