Summary

This document contains guidance on soil gas sampling using
— active sampling (adsorbents, filters, air containers), and
— passive sampling
applied at permanent or temporary monitoring wells or other installations in soils or underneath buildings (sub-slab).
It provides guidance on:
— development of a sampling plan
— construction of monitoring installations
— transport, packaging and storage soil gas samples
— quality assurance.
This document also gives basic information about
— soil gas dynamics, and
— identification of soil gas sources
relevant to permanent or temporary boreholes in soils or underneath buildings (sub‑slab).
The compounds covered by this document are:
— volatile organic compounds (VOCs)
— inorganic volatile compounds (e.g. mercury, HCN)
— permanent gases (i.e. CO2, N2, O2, CH4).
This document does not give guidance on:
— risk evaluation and characterization
— selection and design of protective measures
— the verification of protective measures, although the site investigation methodologies described can be used when appropriate
— the sampling of atmospheric or indoor gases
— the measurement of gases from the soil entering into the atmosphere
— monitoring and sampling for radon.
