水质 采样 第22部分 地下水监测点的设计和安装指南

[中文适用范围]： 本部分 ISO 5667 提供了地下水水质监测点设计、施工和安装的指南，以帮助确保能够获得具有代表性的地下水样品。在指南中考虑了：a) 安装材料对环境的影响；b) 安装对样品完整性的影响；c) 环境对安装及其所用材料的影响。这些指南允许在设计地下水采样方案时考虑和计算这些影响。它们还允许对从现有安装中获得的具有潜在影响的数据和结果进行知情评估。这些指南旨在用于不同环境中的安装和监测，包括建立或监测背景或基线地下水条件的环境，以及调查污染影响的环境。 [外文原描述]： ISO 5667-22:2010 give guidelines for 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 is given to: a) the impact of installation materials on the environment; b) the impact of the installation on sample integrity; c) the impact of the environment on the installation and the materials used in its construction. These guidelines allow the impacts to be considered and accounted for when designing a groundwater sampling programme. They 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. These guidelines are intended for installations and monitoring in different environments including those where background or baseline groundwater conditions are being established or monitored and those in which impacts of contamination are being investigated.
