Full title and description

ISO 10381-7:2005 — Soil quality — Sampling — Part 7: Guidance on sampling of soil gas. This document provides guidance on planning and performing the active sampling of soil gas (permanent gases and volatile organic compounds) from monitoring installations and boreholes for environmental investigation purposes.

Abstract

ISO 10381-7:2005 contains guidance on the sampling of soil gas, including procedures, equipment, sampling plans, sample handling and quality assurance. It excludes measurement of gases emitted to the atmosphere, atmospheric gas sampling and passive sampling procedures.

General information

• Status: Withdrawn (replaced by a later ISO document).
• Publication date: September 2005 (first edition published 2005-09-01).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 13.080.05 (Soil investigation, general).
• Edition / version: Edition 1 (2005).
• Number of pages: 38 pages.

Scope

Provides guidance for the investigation and sampling of soil gas from boreholes and monitoring installations to characterise concentrations and dynamics of permanent gases (e.g., CO2, CH4, O2, N2) and volatile organic compounds (VOCs). It addresses sampling design, technical equipment, sampling procedures, storage/transport, reporting and quality assurance. The standard does not cover sampling of atmospheric gases, the measurement of gases after they have entered the atmosphere, nor passive sampling techniques.

Key topics and requirements

• Investigation objectives and selection of target compounds (permanent gases, VOCs, inorganic volatiles).
• Design of sampling plan and monitoring installations (standpipes, borehole construction, sub-slab access points).
• Sampling techniques for active soil-gas collection, including purging/venting procedures and sample volumes.
• Technical equipment recommendations (portable GC, IR, PID, sorbent tubes, air containers) and field instrumentation.
• Storage, packaging and transport requirements for laboratory analysis and preservation of integrity.
• Requirements for sample documentation, reporting and metadata (site conditions, meteorology, sampling protocol).
• Quality assurance, interferences, method limitations and interpretation guidance for VOCs and permanent gases.

Typical use and users

Used by environmental consultants, site investigation teams, remediation specialists, regulatory agencies and accredited testing laboratories to plan and perform soil-gas surveys at contaminated sites, landfills, industrial areas and beneath buildings (sub-slab). The guidance supports screening, site characterisation and selection of locations for further groundwater or soil assessment.

Related standards

ISO 10381 is a multi-part series on soil-quality sampling (other parts cover design and sampling techniques). ISO 10381-7:2005 has been withdrawn and superseded by ISO 18400-204:2017 (Soil quality — Sampling — Part 204: Guidance on sampling of soil gas). Other related documents include earlier/later parts of the ISO 10381 series and broader ISO soil-quality measurement and sampling standards.

FAQ

Q: What is this standard?

A: ISO 10381-7:2005 is an ISO guidance document titled "Soil quality — Sampling — Part 7: Guidance on sampling of soil gas" that gives practical advice on planning and conducting active soil-gas sampling.

Q: What does it cover?

A: It covers investigation objectives, sampling plans, borehole/monitoring-installation considerations, field sampling procedures for permanent gases and VOCs, equipment, sample handling, reporting and quality assurance, while excluding atmospheric or passive sampling and measurement of gases after release to the atmosphere.

Q: Who typically uses it?

A: Environmental practitioners — consultants, site investigators, remediation teams, laboratories and regulators — involved in contaminated-site assessment, landfill gas surveys and sub-slab vapour investigations.

Q: Is it current or superseded?

A: ISO 10381-7:2005 has been withdrawn (withdrawal recorded 25 January 2017) and its subject matter is covered by the newer standard ISO 18400-204:2017. Users should refer to ISO 18400-204:2017 for current guidance.

Q: Is it part of a series?

A: Yes — ISO 10381 is a multi-part series on soil-quality sampling (different parts address design, techniques and special procedures). The soil-gas guidance was originally part 7 of ISO 10381 and now appears in the ISO 18400 sampling series as part 204.

Q: What are the key keywords?

A: Soil gas, sampling, VOCs, permanent gases, monitoring wells, sub-slab, sampling plan, soil quality, borehole construction, quality assurance.
