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; —selectionanddesignofprotectivemeasures;—theverificationofprotectivemeasures,althoughthesiteinvestigationmethodologiesdescribedcanbeusedwhenappropriate;—thesamplingofatmosphericorindoorgases;—themeasurementofgasesfromthesoilenteringintotheatmosphere;—monitoringandsamplingforradon.
