ISO 19204:2017 describes in a general way the application of the soil quality TRIAD
approach for the site-specific ecological risk assessment of contaminated soils. In detail, it
presents in a transparent way three lines of evidence (chemistry, ecotoxicology and
ecology) which together allow an efficient, ecologically robust but also practical risk
assessment of contaminated soils. This procedure can also be applicable to other stress
factors, such as acidification, soil compaction, salinization, loss of soil organic substance,
and erosion. However, so far, no experience has been gained with these other
applications. Therefore, this document focuses on soils contaminated by chemicals.
NOTE 1 This document focuses on ecological risk assessment. Thus, it does not cover
human health end points.
In view of the nature of this document, the investigation procedure is described on a
general level. It does not contain details of technical procedures for the actual assessment.
However, this document includes references relating to technical standards (e.g. ISO
15799, ISO 17616) which are useful for the actual performance of the three lines of
evidence.
In ecological risk assessment, the effects of soil contamination on the ecosystem are
related to the intended land use and the requirements that this use sets for properly
functioning soil. This document describes the basic steps relating to a coherent tool for a
site-specific risk assessment with opportunities to work out site-specific details.
ISO 19204:2017 can also be used for the evaluation of clean-up operations, remediation
processes or management measures (i.e. for the evaluation of the environmental quality
after having performed such actions).
NOTE 2 This document starts when it has already been decided that an ecological risk
assessment at a given site needs to be performed. In other words, the practical
performance of the soil quality TRIAD and the evaluation of the individual test results will
be described. Thus, nothing will be said about decisions whether (and if yes, how) the
results of the assessment are included in soil management measures or not.
NOTE 3 The TRIAD approach can be used for different parts of the environment, but this
document focuses mostly on the soil compartment. Comparable documents for other
environmental compartments are intended to be prepared in addition (e.g. the terrestrial
aboveground compartment) in order to perform a complete site assessment, based on the
same principles and processes.
