Introduction
An understanding of the purpose of sampling is an essential prerequisite to identifying the principles
to be applied to a particular sampling problem. Examples of the purposes of sampling programmes
commonly devised for rivers and streams are as follows:
a) to determine the suitability of the water quality of a river or stream within a river basin for a
particular use, such as
1) a source of drinking water,
2) for agricultural use (e.g. all types of irrigation, live-stock watering),
3) for the maintenance or development of fisheries,
4) for amenity use (e.g. aquatic sports and swimming), and
5) for conservation and protection of aquatic life;
b) to assess the impact of human activities on the quality of water, such as
1) study of the effects of waste discharge or accidental spillages on a receiving water,
2) assessment of the impact of land use on river or stream quality,
3) assessment of the effect of the accumulation and release of substances including contaminants
from bottom deposits on aquatic biota within the water mass, or on bottom deposits,
4) study of the effects of abstraction, river regulation, and river-to-river water transfers on the
chemical quality of rivers and their aquatic biota, and
5) study of the effects of river engineering works on the water quality (e.g. addition or removal of
weirs, changes to channel or bed structure).

Water quality — Sampling —
Part 6:
Guidance on sampling of rivers and streams
WARNING — The focus of this part of ISO 5667 is the collection and integrity of water samples. The
collection of these samples can be hazardous and attention is therefore drawn to the existence
in some countries of legislative requirements for the safety of personnel. It is essential that all
sampling personnel have had thorough health and safety training for the conditions they are
likely to encounter.
1 Scope
This part of ISO 5667 sets out the principles to be applied to the design of sampling programmes,
sampling techniques, and the handling of water samples from rivers and streams for physical and
chemical assessment.
It is not applicable to the sampling of estuarine or coastal waters nor for microbiological sampling.
[10]
NOTE 1 Procedures for microbiological sampling are given in ISO 19458.
This part of ISO 5667 is neither applicable to the examination of sediment, suspended solids or biota, nor
to dammed stretches of rivers or streams. Also, it is not applicable to passive sampling of surface waters
(see ISO 5667-23).
NOTE 2 In cases where naturally occurring or artificially constructed dams result in the retention or storage
of water for several days or more, the stretch of the river or stream should be considered as a standing water body.
For sampling purposes, see ISO 5667-4.
2 Normative references

indispensable for its application. For dated references, only the edition cited applies. For undated

3.1
automatic sampling
process whereby samples are taken either discretely or continuously, independently of human
intervention, and according to a predetermined programme
[SOURCE: ISO 6107-2:2006, 9]
3.2
composite sample
two or more samples or sub-samples, mixed together in appropriate known proportions (either
discretely or continuously), from which the average value of a desired characteristic can be obtained
Note 1 to entry: The proportions are usually based on time or flow measurements.
[SOURCE: ISO 6107-2:2006, 29]
3.3
continuous sampling
process whereby a sample is taken continuously from a body of water
[SOURCE: ISO 6107-2:2006, 32]
3.4
discrete sampling
process whereby single samples are taken from a body of water
[SOURCE: ISO 6107-2:2006, 40]
3.5
incremental sampling
technique in which small samples are taken because of a low flow rate (with the possibility of
contamination by bottom deposits) or because of restricted access (e.g. where a sample is obtained
through a small aperture), these small samples then being aggregated to form a composite sample
Note 1 to entry: All the liquid contained in the small samples is used, unlike blending of aliquots used to make a
flow-proportional sample (see 9.4).
3.6
isokinetic sampling
technique in which the sample from a water stream passes into the orifice of a sampling probe with a
velocity equal to that of the stream in the immediate vicinity of the probe
[SOURCE: ISO 6107-2:2006, 56]
3.7
light non-aqueous-phase liquid
LNAPL
organic compound that has low water solubility and a density less than that of water

random sampling
form of sampling whereby the chances of obtaining different concentration values of a determinand are
precisely those defined by the probability distribution of the determinand in question

3.13
sub-sample
portion removed from a sample and intended to be representative of that sample
3.14
systematic sampling
sampling whereby the samples are taken at predetermined intervals, often equally spaced in time
4 Design of sampling programme
Sampling is usually the first step in carrying out an investigation and largely determines the quality
of the whole investigation. It is therefore recommended that a detailed sampling strategy be drawn
up, often based upon a preliminary investigation in which an assessment has identified the important
aspects. Both the purpose and the ambient situation determine the way in which the sampling is carried
out. Consideration of time-of-travel data can influence choice of sampling locations depending on the
objective of the survey. General aspects for sampling programme design can be found in ISO
