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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
The ISO 22932 series has been prepared in order to standardize and to co-ordinate the global use of
technical terms and definitions in mining, for the benefit of the experts working on different types of mining
activities.
The need for the ISO 22932 series arose from the widely varying interpretation of terms used within the
industry and the prevalent use of more than one synonym.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp

3.1 Ground water
3.1.1
aquifer
porous water bearing stratum
3.1.2
aquifer test
in situ procedure, such as single-well (bail test or slug test) and multiple-well pumping (3.3.5.9) tests, used to
determine hydraulic properties of an aquifer
Note 1 to entry: See Reference [1].
3.1.3
aquifuge
rock that contains no interconnected openings or interstices and therefore neither absorbs nor transmits water
Note 1 to entry: That can be as the opposite of aquifer.
Note 2 to entry: Compare with confining bed.
Note 3 to entry: See Reference [1].
3.1.4
attached ground water
that portion of the subsurface water adhering to the pore walls
Note 1 to entry: It is assumed to be equal in quantity to the pellicular water, and it is measured by specific retention.
Note 2 to entry: See Reference [1].

3.1.5
capillary
action by which the surface of a liquid is elevated at the point at which it is in contact with a solid
Note 1 to entry: Such as in a lamp wick.
Note 2 to entry: See Reference [1].
3.1.5.1
capillarity
capillary action
action by which a fluid, such as water, is drawn up (or depressed) in small interstices or tubes as a result of
surface tension
Note 1 to entry: See Reference [1].
3.1.5.2
zone of capillarity
subsurface zone that overlies the zone of saturation (3.1.20) in which capillary (3.1.5) voids hold water above
the zone of saturation (3.1.20) by molecular attraction acting against gravity
Note 1 to entry: Compare with zone of aeration.
Note 2 to entry: See Reference [1].
3.1.6
confining bed
aquiclude
impervious stratum above and/or below an aquifer
Note 1 to entry: Compare with aquifuge.
3.1.7
connate water
inherent water contemporary with the rocks containing it, as opposed to water subsequently permeating
the rocks
Note 1 to entry: Compare with interstitial water and formation water.
3.1.8
depressed water level
pumping water level
lowest level of ground water (3.1.10) during drainage (3.2.3.2) or pumping
3.1.9
formation water
native water
water present in a water-bearing formation under natural conditions, as opposed to introduced fluids, such
as drilling mud
Note 1 to entry: Compare with connate water.
Note 2 to entry: See Reference [1].
3.1.10
ground water
meteoric water
subterranean water
water penetrating from the surface and filling naturally the pores and fissures of the strata below the water table

3.1.11
ground water hydrology
aspect of hydrology (3.1.13) which is concerned with the physical and chemical characteristics of water and
similar liquids found in the ground
3.1.12
ground water province
area or region in which geology and climate combine to produce ground-water conditions consistent enough
to permit
