Soil quality - Sampling - Part 104: Strategies
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— the average properties of soil,— the variability of soil properties, and— the spatial distribution of soil properties.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.NOTE 1 This document also provides information on the statistical principles underlying the development of appropriate sampling strategies and statistical methodologies.NOTE 2 Guidance on other forms of related sampling activities are given in other International Standards [for soil gas (ISO 18400-204) and for biological testing purposes (ISO 18400-206)]. Guidance on sampling groundwater is provided in ISO 5667-11 and ISO 5667-22 and on sampling methods and groundwater measurements in geotechnical investigations in ISO 22475-1.
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
— the average properties of soil,
— the variability of soil properties, and
— the spatial distribution of soil properties.
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.
NOTE 1 This document also provides information on the statistical principles underlying the development of appropriate sampling strategies and statistical methodologies.
NOTE 2 Guidance on other forms of related sampling activities are given in other International Standards [for soil gas (ISO 18400-204) and for biological testing purposes (ISO 18400-206)]. Guidance on sampling groundwater is provided in ISO 5667-11 and ISO 5667-22 and on sampling methods and groundwater measurements in geotechnical investigations in ISO 22475-1.
ISO 10381-1:2002 sets out the general principles to be applied in the design of sampling programmes for the purpose of characterizing and controlling soil quality and identifying sources and effects of contamination of soil and related material, with emphasis on procedures required to locate points from which samples may be taken for examination or at which instruments may be installed for in situ measurement including statistical implications,procedures for determining how much sample to collect and whether to combine samples,methods of collecting samples,methods for containing, storing and transporting samples to prevent deterioration/contamination.
ISO 10381-4:2003 describes the sampling of soils of natural and near-natural sites;areas used for agriculture (arable and pasture sites);areas used for horticulture (including domestic gardens, allotments);areas used for special crop-cultivation, arboreal, vineyard, etc.;forest areas and woods. It is applicable to soil investigations and evaluations in the field;chemical, geochemical, physical, biological and radiological characterization of soil and soil materials in the laboratory after sampling. ISO 10381-4:2003 sets out appropriate strategies for the design of sampling programmes, field procedures and subsequent treatment of samples for transport and storage prior to sample pretreatment (e.g. drying, milling). NOTE ISO 10381-4:2003 is intended to be used in conjunction with the other parts of ISO 10381 when appropriate.
ISO 10381-5:2005 gives guidance on the procedure for the investigation of urban and industrial sites, where either it is known that soil contamination is present, or the presence of soil contamination is suspected. ISO 10381-5:2005 is applicable where there is a need to establish the contamination status of the site, or there is a need to establish the environmental quality of the site for other purposes. ISO 10381-5:2005 includes guidance on the collection of information that is necessary for risk assessment and/or the development of remedial action plans (e.g. whether remediation is required, and suggestions as to how this might be best achieved). It provides guidance on the information required in general; specific remediation methods may need additional information. ISO 10381-5:2005 is also applicable to sites where no soil contamination is expected, but the soil quality is to be determined (e.g. to make sure that there is no contamination present).
ISO 10381-6:2009 provides guidance on the collection, handling and storage of soil for subsequent testing under aerobic conditions in the laboratory. The recommendations in this document are not applicable to the handling of soil where anaerobic conditions are to be maintained throughout. ISO 10381-6:2009 is mainly applicable to temperate soils. Soils collected from extreme climates (e.g. permafrost, tropical soils) may require special handling.
ISO 10381-8:2006 defines the methods that should be applied when sampling soil from stockpiles. ISO 10381-8:2006 only includes the sampling of the soil material itself, i.e. the solid phase. The underlying reason for sampling the soil can differ widely, as can the subsequent analysis on the obtained samples. ISO 10381-8:2006 gives guidance on the various aspects that, together, describe the sampling activity: the definition of a sampling plan; the choice of an adequate sampling strategy; the sampling technique to be applied; the sample pretreatment directly after sampling (when necessary); and the packing, preservation, storing, transport and delivery of the sample. Given the wide differences in circumstances for all of the above-mentioned sampling steps, ISO 10381-8:2006 provides information on how to obtain clear and simple instructions for the sampling personnel.
