Overview
EN ISO 5667-1:2023 - "Water quality - Sampling - Part 1" (CEN adoption of ISO 5667-1:2023) provides general principles and guidance for the design of sampling programmes and sampling techniques for all aspects of water sampling. The scope covers surface waters, groundwaters, drinking water, waste waters, sludges, effluents, suspended solids and sediments. It gives high‑level direction on programme design, safety, environmental considerations and factors affecting sampling but does not give detailed, situation‑specific procedures (these are covered in other parts of the ISO 5667 series and ISO 19458).
Key topics and technical requirements
- Design of sampling programmes: objectives, duration, frequency, statistical considerations and how to define sampling occasions to represent variability in water quality.
- Sampling techniques and location: guidance on selecting sampling locations and techniques appropriate to the target matrix (water, sludge, sediments, suspended solids).
- Variability and representativeness: considerations for temporal, spatial and process-related variability; use of composite samples vs discrete samples.
- Flow measurement: when and how flow data are relevant for interpreting water quality results (direction, velocity, discharge rate, flow profile).
- Personnel, safety and environmental considerations: responsibilities, training, personnel safety and minimizing environmental impact during sampling.
- Quality assurance / quality control: reference to QA/QC principles for sampling and handling (see related standards).
- References to specific parts of ISO 5667 and other standards: links to preservation and handling (ISO 5667-3), QA/QC (ISO 5667-14), sludge/sediment handling (ISO 5667-15), microbiological sampling (ISO 19458), and other Parts (4–26) that give detailed methods for specific waters.
Applications and users
This standard is practical for organizations involved in environmental and drinking water assessment and monitoring:
- Water utilities and treatment operators
- Environmental and regulatory agencies
- Laboratories and field sampling teams
- Consultants, researchers and academics conducting water quality studies
- Industrial effluent monitoring programs
Use cases include designing monitoring programmes for compliance, trend analysis, incident investigation, site characterization and research studies where representativeness and data quality are essential.
Related standards
Relevant parts referenced in EN ISO 5667-1:2023 include (selection):
- ISO 5667-3 (preservation and handling)
- ISO 5667-14 (QA/QC of sampling and handling)
- ISO 5667-15 (preservation/handling of sludge and sediment)
- ISO 19458 (microbiological sampling)
- Multiple ISO 5667 Parts for specific water types (Parts 4–13, 16–26)
EN ISO 5667-1:2023 is a foundational guidance document for any water sampling programme and should be used alongside the specific part(s) of the ISO 5667 series relevant to the water type or analysis.

4 General safety precautions
4.1 General
Attention is drawn to the requirements of national and/or regional health and safety regulations.
The following are general examples of safety considerations.
4.2 Safety of personnel
The enormously wide range of conditions encountered in sampling water bodies and bottom sediments
can subject sampling personnel to a variety of safety and health risks. Precautions should be taken
to avoid inhalation of toxic gases and ingestion of toxic materials through the nose, mouth and skin.
Personnel responsible for the design of sampling programmes and for carrying out sampling operations
should ensure that sampling personnel are informed of the necessary precautions to be taken in
sampling operations.
Weather conditions should be taken into account in order to ensure the safety of personnel and
equipment and it is essential that life jackets and lifelines should be worn when sampling large masses
of water. Before sampling from ice-covered waters, the location and extent of weak ice should be
carefully checked. If self-contained underwater breathing apparatus or other diving equipment is used,
ISO 5667-1:2023(E)
it should always be checked and maintained in accordance with relevant ISO or national standards to
ensure reliability.
Boats or platforms used for sampling purposes should be capable of being maintained in a stable
condition. In all waters, precautions should be taken in relation to commercial ships and fishing
vessels; for example, the correct signal flags should be flown to indicate the nature of the work being
undertaken.
Sampling from unsafe sites, such as unstable river banks, should be avoided wherever possible. If this
is not possible, the operation should be conducted by a team using appropriate precautions rather than
by a single operator. Wherever possible, sampling from bridges should be used as a substitute for bank
sampling unless bank conditions are the specific subject of the sampling study.
Safe access to sampling sites in all weather is essential for frequent routine sampling. Where relevant,
precautions should be taken where additional natural hazards are present, such as fauna or flora, that
can endanger the health or safety of personnel.
Hazardous materials (e.g. bottles containing concentrated acids) should be properly labelled.
If instruments or other items of equipment are to be installed on a river bank for sampling purposes,
locations that are susceptible to flooding or vandalism should be avoided or appropriate precautions
taken.
Many other situations arise during the sampling of water when special precautions should be taken
to avoid accidents. For example, some industrial effluents can be corrosive or can contain toxic or
flammable materials. The potential dangers associated with contact with sewage should also not be
overlooked; these can be gaseous, microbiological, radiological, virological or zoological, such as from
amoebae or helminthes.
Gas protection equipment, breathing apparatus, resuscitation apparatus and other safety equipment
should be available when sampling personnel need to enter sampling locations containing hazardous
atmospheres. In addition, the concentration of oxygen and of any likely toxic or asphyxiating vapour or
gas likely to be present should be measured before personnel enter enclosed spaces.
In the sampling of steam and hot discharges, special care is necessary, and recognized sampling
techniques designed to remove hazards should be applied.
The handling of radioactive samples requires special care, and the special techniques required should
be strictly applied.
The use of electrically operated sampling equipment in or near water can present special electrocution
hazards. Work procedures, site design and equipment maintenance should be planned so as to minimize
these hazards. Where appropriate, specific materials and equipment, for example, ‘atmosphere
explosible’ equipment, should be used.
4.3 General environmental considerations
While working in the field environmental protection should be observed. In any sampling activity there
should be measures taken to avoid environmental impacts on the sampling site surroundings and the
working space.
Measures should be designed to avoid any harm to flora and fauna when installing equipment using
machinery (subsoil compaction) or when developing the access and egress form the site.
5 Design of sampling programmes
5.1 General
Whenever a volume of water, suspended solids, bottom sediment or sludge is to be characterized, it is
generally impossible to examine the whole and it is therefore necessary to take samples.
ISO 5667-1:2023(E)
Samples are collected and examined primarily for the following reasons:
a) to determine the concentration of associated physical, chemical, microbiological, biological and
radiological parameters in space and time;
b) with bottom sediments, to obtain a visual indication of their nature;
c) to estimate the flux of material;
d) to assess trends over time or over space;
e) for conformance with, or attainment of, criteria, standards or objectives.
Sampling programmes, the outcome of which will be estimates of summary statistics and trends,
should be designed in full awareness of the issues of statistical sampling error and the techniques by
which these errors are quantified and how they are used to take decisions.
The samples collected should be as representative as possible of the whole to be characterized, and all
precautions should be taken to ensure that, as far as possible, the samples do not undergo any changes
in the interval between sampling and analysis (see ISO 5667-3 for additional guidance). The sampling
of multiphase systems, such as water containing suspended solids or immiscible organic liquids, can
present special problems and in such cases, specific advice should be sought (see Clause 6).
5.2 Sampling personnel
Attention is drawn to the fact that certification and accreditation of the sampling process and the
individuals implementing it can be required or recommended at national level. Also refer to 7.2.6,
ISO 5667-14 and ISO 5667-24.
5.3 Broad objectives for the design of sampling programmes
Before any sampling programme is devised, it is very important that the objectives of the programme
are carefully established since they are the major factors in determining the position of sampling sites,
frequency of sampling, duration of sampling, sampling procedures, subsequent treatment of samples
and analytical requirements. The degree of accuracy and precision necessary for the estimation of
parameter concentrations sought should also be taken into account, as should the manner in which
the results are to be expressed and presented, for example, as concentrations or mass loads, maximum
and/or minimum values, arithmetic means, median values, etc. The sampling programme should be
designed to be capable of estimating the error in such values as affected by statistical sampling error
and errors in chemical analysis.
Additionally, a list of parameters of interest should be compiled and the relevant analytical procedures
consulted since these can give guidance on precautions to be observed during sampling and subsequent
handling (general guidance on handling of samples is given in ISO 5667-3).
It can often be necessary to carry out a preliminary sampling and analysis programme before the
final objectives can be defined. It is important to take into account all relevant data from previous
programmes at the same or similar locations and other information on local conditions. Previous
personal experience of similar programmes or situations can also be very valuable when setting up
a new programme for the first time. Putting sufficient effort in time and money into the design of a
proper sampling programme is a good investment that will ensure that the required information is
obtained both efficiently and economically; failure to put proper effort into this aspect can result in
either failure of the programme to achieve its objectives and/or over-expenditure of time and money.
Three broad objectives can be distinguished as follows (these are covered in more detail in 8.2, 8.3 and
8.4):
— quality control measurements within water or waste water treatment plants used to decide when
short-term process corrections are required;
ISO 5667-1:2023(E)
— quality characterization measurements used to estimate quality, perhaps as part of a research
project, for setting and measuring performance targets against regulatory targets, for long-term
control purposes or to indicate long-term trends;
— identification and control of sources of contamination.
The purpose of the programme can change from quality characterization to quality control and vice-
versa. For example, a longer-term programme for nitrate characterization can become a short-term
quality control programme requiring increased frequency of sampling as the nitrate concentration
approaches a critical value.
No single sampling study can satisfy all possible purposes. It is therefore important that specific
sampling programmes are optimized for specific study purposes, such as the following:
a) to determine the suitability of water for an intended use and, if necessary, to assess any treatment
or control requirements, for example, to examine borehole water for cooling, boiler feed or process
purposes or, if a natural spring, as a possible source of water intended for human consumption;
