ISO 18400-204:2017 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.

ISO 18400-204:2017 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).

ISO 18400-204:2017 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.
