Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15175 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 7, Soil and site

4 General
Soils are of central importance within the water cycle because their storage and filter functions have a lasting
influence on the water balance and groundwater quality. In this context, particular attention shall be paid to the
following functions:
 mechanical filter functions (retention of suspended sludge and pollutant particles);
 chemical filter functions (sorption and mobilization of substances);
 transformation functions (degradation or transformation of substances).
Soil is understood as a porous medium consisting of three phases: the solid phase, the liquid phase and the
gaseous phase. The ratio of these phases and their respective compositions vary widely in time and space.
The assessment of contamination affecting groundwater quality requires a profound understanding of the
governing processes and reactions of potentially toxic compounds in soils. Contaminants are translocated in
all three phases of soils as a function of the properties of the chemicals and the soil. Hence strategies for
assessing risks to groundwater due to soil contamination should vary with the contaminants considered, and
should take into account those soil properties which mainly govern the soil's filter, retention, release and
transformation functions.
In addition to considering the properties of the chemicals and the soil governing the behaviour of contaminants
in soils, different ways for contaminants to enter soils shall also be evaluated when designing suitable risk
assessment strategies, with respect to contamination of groundwater. Soil and groundwater contamination
can be caused by different sources on different spatial scales, as indicated in Figure 1. On regional and larger
scales, soil contamination is caused, for example, by wet and dry atmospheric deposition and has
predominantly diffuse character on a moderate level of contamination. On a local scale, a variety of point
sources can cause all kinds and magnitudes of soil and groundwater contamination. Most point sources of
contamination may also be regarded as off-site diffuse sources of groundwater contamination. It is evident
that different contamination scenarios as a function of contamination sources and scale demand different
investigation strategies with respect to groundwater impact. At present there are no uniform principles for the
investigation and evaluation of contaminated soils and contaminated sites in relation to the protection of water
resources.

ISO 15175:2004(E)
Investigation strategies may be qualitative or quantitative. Qualitative approaches mostly refer to assessment
of, for example, the potential leaching risk of chemicals through the soil towards groundwater. In contrast to
quantitative approaches, the level of actual soil contamination is not taken into account. Approaches of this
type can also be utilized, e.g. to classify larger areas with respect to their capability of protecting groundwater
resources against contamination, or as an introductory step in an assessment of an actual contaminated site.
To assess the on-site impact on groundwater resulting from specific soil contamination, quantitative
approaches based on site-specific investigation procedures including laboratory and/or field measurements
have to be carried out. Laboratory measurements can include physical, chemical and biological analysis, and
leaching tests. Assessments of this kind also shall take into account natural background concentrations of a
substance and other natural conditions affecting the impact on the groundwater. Assessments of impact on
groundwater often include a temporal aspect, since the actual impact may not be measurable at the time of
the investigation, but may happen some time in the future.
Assessments also depend on the purposes of investigations, for example:
 conservation of soil functions in order to prevent groundwater contamination;
 soil and groundwater monitoring;
 risk assessment;
 controlling remediation measures.
A listing of suitable methods are covered in the main part of this International Standard (see Clause 5). Some
examples of assessment using principles of this International Standard are provided in Annexes A and B.
Since the impact on groundwater can lead to impact on surface waters, this aspect can in some cases be
relevant in an overall impact assessment. This issue is not addressed explicitly in this International Standard.
5 Site assessment
5.1 General
A prerequisite for the evaluation of the soil-to-groundwater pathway is the determination of the relevant
physical, chemical and biological characteristics of soils and the hydrological characteristics of the site. It is
therefore normally necessary to collect data for the assessment of the contamination source with respect to
the type and degree of contamination and extent of source(s).
It is also necessary to describe the soil compartment that is influenced by the source, and the factors in this
compartment affecting the actual impact on the groundwater. Many processes influence the groundwater
impact in this soil compartment, where a number of physical, chemical and biological processes can take
place. In order to evaluate the importance of these processes in a specific assessment, it is necessary to
describe the structure of the soil compartment, e.g. the geometry, hydraulic conditions and natural chemical
and biologic processes. Input to the soil compartment includes the infiltration of water and specific
contaminants. Output is the contaminant flux to the compartment of the groundwater zone investigated. A
general description hereof is given in Figure 2 and a further description of the relevant parameters is given
in 5.2.

---------------------- Page: 13 ----------------------
ISO 15175:2004(E)

Figure 2 — Schematic diagram illustrating the soil compartment covered by the assessment
procedure and processes affecting the impact of contamination on groundwater
The types of information needed to describe the relevant soil compartment include pedology, lithology of
parent material, pedology (e.g. soil unit), hydrogeology (e.g. permeability), physico-chemical conditions (e.g.
pH) and biological conditions (e.g. substrate availability). How large the actual soil compartment investigated
should be (and thus the detail of the investigation) depends on the type of assessment chosen. For example,
the volume is large if the assessment focuses on the general use of pesticides and fertilizers in an area
covering a groundwater reservoir used as a drinking water source. The area and volume of the soil
compartment investigated is considerably smaller if the assessment covers a “hot spot” on a contaminated
site with a groundwater-pumping well located on a neighbouring site.
5.2 Relevant soil processes
Contaminant transport in the unsaturated zone is governed not only by the transport of percolating water but
also by a number of biological and chemical processes. Which of these processes are to be considered
important within a given context will depend on the type of contaminants and the actual soil conditions. An
overview of soil and contaminant parameters related to contaminant transport is given in Table 1.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15175 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 7, Soil and site
assessment.

4 General
Soils are of central importance within the water cycle because their storage and filter functions have a lasting
influence on the water balance and groundwater quality. In this context, particular attention shall be paid to the
following functions:
 mechanical filter functions (retention of suspended sludge and pollutant particles);
 chemical filter functions (sorption and mobilization of substances);
 transformation functions (degradation or transformation of substances).
Soil is understood as a porous medium consisting of three phases: the solid phase, the liquid phase and the
gaseous phase. The ratio of these phases and their respective compositions vary widely in time and space.
The assessment of contamination affecting groundwater quality requires a profound understanding of the
governing processes and reactions of potentially toxic compounds in soils. Contaminants are translocated in
all three phases of soils as a function of the properties of the chemicals and the soil. Hence strategies for
assessing risks to groundwater due to soil contamination should vary with the contaminants considered, and
should take into account those soil properties which mainly govern the soil's filter, retention, release and
transformation functions.
In addition to considering the properties of the chemicals and the soil governing the behaviour of contaminants
in soils, different ways for contaminants to enter soils shall also be evaluated when designing suitable risk
assessment strategies, with respect to contamination of groundwater. Soil and groundwater contamination
can be caused by different sources on different spatial scales, as indicated in Figure 1. On regional and larger
scales, soil contamination is caused, for example, by wet and dry atmospheric deposition and has
predominantly diffuse character on a moderate level of contamination. On a local scale, a variety of point
sources can cause all kinds and magnitudes of soil and groundwater contamination. Most point sources of
contamination may also be regarded as off-site diffuse sources of groundwater contamination. It is evident
that different contamination scenarios as a function of contamination sources and scale demand different
investigation strategies with respect to groundwater impact. At present there are no uniform principles for the
investigation and evaluation of contaminated soils and contaminated sites in relation to the protection of water
resources.

SIST ISO 15175:2006
ISO 15175:2004(E)
Investigation strategies may be qualitative or quantitative. Qualitative approaches mostly refer to assessment
of, for example, the potential leaching risk of chemicals through the soil towards groundwater. In contrast to
quantitative approaches, the level of actual soil contamination is not taken into account. Approaches of this
type can also be utilized, e.g. to classify larger areas with respect to their capability of protecting groundwater
resources against contamination, or as an introductory step in an assessment of an actual contaminated site.
To assess the on-site impact on groundwater resulting from specific soil contamination, quantitative
approaches based on site-specific investigation procedures including laboratory and/or field measurements
have to be carried out. Laboratory measurements can include physical, chemical and biological analysis, and
leaching tests. Assessments of this kind also shall take into account natural background concentrations of a
substance and other natural conditions affecting the impact on the groundwater. Assessments of impact on
groundwater often include a temporal aspect, since the actual impact may not be measurable at the time of
the investigation, but may happen some time in the future.
Assessments also depend on the purposes of investigations, for example:
 conservation of soil functions in order to prevent groundwater contamination;
 soil and groundwater monitoring;
 risk assessment;
 controlling remediation measures.
A listing of suitable methods are covered in the main part of this International Standard (see Clause 5). Some
examples of assessment using principles of this International Standard are provided in Annexes A and B.
Since the impact on groundwater can lead to impact on surface waters, this aspect can in some cases be
relevant in an overall impact assessment. This issue is not addressed explicitly in this International Standard.
5 Site assessment
5.1 General
A prerequisite for the evaluation of the soil-to-groundwater pathway is the determination of the relevant
physical, chemical and biological characteristics of soils and the hydrological characteristics of the site. It is
therefore normally necessary to collect data for the assessment of the contamination source with respect to
the type and degree of contamination and extent of source(s).
It is also necessary to describe the soil compartment that is influenced by the source, and the factors in this
compartment affecting the actual impact on the groundwater. Many processes influence the groundwater
impact in this soil compartment, where a number of physical, chemical and biological processes can take
place. In order to evaluate the importance of these processes in a specific assessment, it is necessary to
describe the structure of the soil compartment, e.g. the geometry, hydraulic conditions and natural chemical
and biologic processes. Input to the soil compartment includes the infiltration of water and specific
contaminants. Output is the contaminant flux to the compartment of the groundwater zone investigated. A
general description hereof is given in Figure 2 and a further description of the relevant parameters is given
in 5.2.

Figure 2 — Schematic diagram illustrating the soil compartment covered by the assessment
procedure and processes affecting the impact of contamination on groundwater
The types of information needed to describe the relevant soil compartment include pedology, lithology of
parent material, pedology (e.g. soil unit), hydrogeology (e.g. permeability), physico-chemical conditions (e.g.
pH) and biological conditions (e.g. substrate availability). How large the actual soil compartment investigated
should be (and thus the detail of the investigation) depends on the type of assessment chosen. For example,
the volume is large if the assessment focuses on the general use of pesticides and fertilizers in an area
covering a groundwater reservoir used as a drinking water source. The area and volume of the soil
compartment investigated is considerably smaller if the assessment covers a “hot spot” on a contaminated
site with a groundwater-pumping well located on a neighbouring site.
5.2 Relevant soil processes
Contaminant transport in the unsaturated zone is governed not only by the transport of percolating water but
also by a number of biological and chemical processes. Which of these processes are to be considered
important within

4 Généralités
Les sols ont une importance centrale dans le cycle de l'eau car leurs fonctions de stockage et de filtration ont
une influence durable sur le bilan hydrologique et sur la qualité des eaux souterraines. Dans ce contexte, une
attention particulière doit être portée aux fonctions suivantes:
 fonctions de filtration mécanique (rétention des boues en suspension et des particules de polluant);
 fonctions de filtration chimique (adsorption et mobilisation des substances);
 fonctions de transformation (dégradation ou transformation des substances).
Le sol doit être considéré comme un milieu poreux constitué de trois phases: la phase solide, la phase liquide
et la phase gazeuse. Le rapport entre ces trois phases et leurs compositions respectives varie dans de
grandes proportions en fonction du temps et de l'espace.
L'évaluation de la pollution affectant la qualité des eaux souterraines requiert une très bonne compréhension
des processus fondamentaux et des réactions des composés potentiellement toxiques dans les sols. Les
contaminants se répartissent entre les trois phases des sols en fonction des propriétés des composés
chimiques et du sol. Ainsi, il convient que les stratégies d'évaluation des risques pour les eaux souterraines
dus à la pollution du sol varient en fonction des contaminants considérés et prennent en compte les propriétés
du sol qui régissent principalement les fonctions de filtration, de rétention, d'émissions et de transformation du
sol.
Outre l'étude des propriétés des substances chimiques et celles du sol régissant le comportement des
contaminants dans les sols, on doit également évaluer les différents modes de pénétration des contaminants
dans les sols lors de l'établissement de stratégies adaptées d'évaluation des risques, du point de vue de la
pollution des eaux souterraines. La pollution des sols et des eaux souterraines peut provenir de différentes
sources, à des échelles spatiales variées, comme le montre la Figure 1. À l'échelle régionale ou à plus grande
échelle, la pollution des sols est provoquée, par exemple, par des dépôts d'origine atmosphérique secs ou
humides, et elle présente un caractère principalement diffus avec un niveau de pollution modéré. À l'échelle

---------------------- Page: 11 ----------------------
ISO 15175:2004(F)
locale, différents types de sources ponctuelles peuvent provoquer des pollutions du sol et des eaux
souterraines de toutes natures et de tous degrés. La plupart des sources ponctuelles de pollution peuvent
également être considérées comme des sources diffuses hors site de pollution des eaux souterraines. Il est
évident que des scénarios de pollution différents en fonction des sources de pollution et de l'échelle de cette
pollution exigent des stratégies d'investigation différentes concernant l'impact sur les eaux souterraines. Il
n'existe actuellement aucun principe uniforme présidant à l'investigation et à l'évaluation des sols et des sites
pollués en relation avec la protection des ressources en eau.

ISO 15175:2004(F)
Les stratégies d'investigation peuvent être qualitatives ou quantitatives. Les méthodes qualitatives font le plus
souvent référence à l'évaluation, par exemple, des risques potentiels de lixiviation de produits chimiques à
travers le sol vers les eaux souterraines. Contrairement aux méthodes quantitatives, le niveau réel de
pollution du sol n'est pas pris en compte. Des approches de ce type peuvent également être utilisées, par
exemple pour la classification de zones plus étendues en fonction de leur capacité à protéger de la pollution
les ressources des eaux souterraines, ou en guise d'étape préliminaire dans l'évaluation d'un site réel pollué.
Pour évaluer l'impact sur site d'une pollution particulière du sol sur les eaux souterraines, on doit utiliser des
méthodes quantitatives basées sur les procédures spécifiques d'investigation sur site, incluant des mesures
en laboratoire et/ou sur le terrain. Les mesures en laboratoire peuvent comprendre des analyses physiques,
chimiques et biologiques et des essais de lixiviation. Les évaluations de cette nature doivent également
prendre en compte le fond (hydro)chimique naturel d'une substance et toute autre condition naturelle
influençant l'impact sur les eaux souterraines. Les évaluations de l'impact sur les eaux souterraines
intégreront souvent un aspect temporel, car il se peut que l'impact réel ne soit pas mesurable au moment de
l'investigation, mais se produise à un certain moment dans le futur.
Les évaluations dépendent également de la raison des investigations, par exemple:
 préservation des fonctions du sol visant à éviter la pollution des eaux souterraines;
 surveillance des sols et des eaux souterraines;
 évaluation des risques;
 contrôle des mesures de dépollution.
La partie principale de la présente Norme internationale (voir l'Article 5) couvre une liste des méthodes
applicables. Un certain nombre d'exemples d'évaluation utilisant les principes de la présente Norme
internationale sont donnés dans les Annexes A et B.
Comme l'impact sur les eaux souterraines peut entraîner un impact sur les eaux de surface, cet aspect peut
s'avérer dans certains cas pertinent dans une évaluation globale de l'impact. Ce problème n'est pas traité de
manière explicite dans la présente Norme internationale.
