scope:

The objective of this Part of ISO 5667 is to provide guidance on the design, construction and installation of groundwater quality monitoring points to help ensure that representative samples of groundwater can be obtained. Within the guidance consideration will be given to: . the impact of installation materials on the environment; . the impact of the installation on sample integrity; . the impact of the environment on the installation and the materials used in its construction. This guidance will allow the impacts to be considered and accounted for when designing a groundwater sampling programme. It will also allow an informed assessment of data and results obtained from existing installations, the construction of which can potentially have an impact on sample integrity. The guidance will be aimed at installations and monitoring in different environments including those where background/baseline groundwater conditions are being established/monitored and those in which impacts of contamination are being investigated.
