17、) 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 repr

18、esented 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 ar

19、e 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 Internation

20、al Standard requires approval by at least 75 % of the member bodies casting a vote.

28、vi ISO 2009 All rights reservedIntroduction This part of ISO 5667 is a revision of both ISO 5667-11:1993, Guidance on sampling of groundwaters and ISO 5667-18:2001, Guidance on sampling of groundwater at contaminated sites. The guidance in this part of ISO 5667 can be used in parallel with other gui

29、dance on water quality sampling and/or investigation of contaminated or potentially contaminated sites, as any groundwater sampling from such sites is likely to form part of a much wider investigation programme. Development of a groundwater sampling programme depends on the purposes of the investiga

30、tion. A definition of the purpose of groundwater sampling is an essential prerequisite for identifying the principles to be applied to a particular sampling problem. The principles set out in this part of ISO 5667 can be used to satisfy the following more detailed objectives: a) to determine the sui

31、tability of groundwater as a source of drinking water or industrial/agricultural water; b) to identify, at an early stage, contamination of aquifers caused by potentially hazardous surface or sub-surface activities (e.g. the operation of waste disposal sites, land contamination, industrial developme

32、nts, mineral exploitation, agricultural practices, changes in land use) and its potential to impact on surface waters and other potential receptors in the vicinity of the site; c) to establish whether migration of contaminants is occurring in order to assess the impact on groundwater quality and to

33、calibrate and validate suitable groundwater quality models; d) to develop an understanding of groundwater quality and flow variations, including those caused by deliberate actions (e.g. variations in groundwater pumping regimes, groundwater recharge caused by effluent, surface clean-up activities ar

34、ising from contaminated sites), in order to achieve optimal resource management, provide data for undertaking risk assessment and to enable enforcement of pollution-control law; e) to assist in the selection of remedial measures and remediation process design, and monitor the performance and effecti

35、veness of these measures or facility design; f) to demonstrate compliance with licence conditions, or collect evidence for regulatory purposes; g) to identify and characterise discrete aquifer water bodies. Examples of situations where this guidance can be used include: g127 general surveys of groun

36、dwater quality for chemical and microbiological assessment; g127 investigation of present or former industrial sites with a history of potentially contaminatory activities; g127 groundwater investigation and monitoring of waste disposal (landfill) sites; g127 investigation of sites where natural and

37、/or artificial processes have led to potential land and groundwater contamination; g127 investigation of sites where products have been spilled or released as a result of accidents or other unforeseen events, e.g. transportation accidents. The guidance contained in this part of ISO 5667 covers selec

38、tion of sampling points, selection of sampling installations and devices, groundwater parameter selection and sampling frequency. BS ISO 5667-11:2009ISO 5667-11:2009(E) ISO 2009 All rights reserved viiPrescriptive guidance on methods and applications is not possible. Therefore, this guidance provide

39、s information on the most commonly applied, and available, techniques and lists their advantages, disadvantages and limitations of use where these are known. When considering design of sampling strategies, the properties of the groundwater (aquifer) system, monitoring point design, contaminant sourc

40、e(s), pathways for migration and the receptors need to be considered.

41、 the sampling of groundwaters. It informs the user of the necessary considerations when planning and undertaking groundwater sampling to survey the quality of groundwater supply, to detect and assess groundwater contamination and to assist in groundwater resource management, protection and remediati

42、on. This part of ISO 5667 does not apply to sampling related to the day-to-day operational control of groundwater abstractions for potable purposes. The guidance includes sampling of groundwater from both the saturated (below water table) zone and the unsaturated (above the water table) zone. 2 Norm
