BS ISO 5667-11:2009 Water quality. Sampling. Guidance on sampling of groundwaters BS ISO 5667-11 gives guidance on water quality sampling and investigation of contaminated or potentially contaminated sites. It can be used with other guidance documents 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 investigation.  A definition of the purpose of groundwater sampling is therefore essential before any investigation. BS ISO 5667-11 can be used to: a) Determine the suitability of groundwater as a source of drinking water or industrial/agricultural water b) 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 developments, mineral exploitation, agricultural practices, and changes in land use) c) Establish whether migration of contaminants is occurring in order to assess the impact on groundwater quality d) 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 arising from contaminated waste disposal sites), in order to achieve optimal resource management, provide data for undertaking risk assessment and to enable enforcement of pollution-control law e) Assist in the selection of remedial measures and remediation process design and monitor the performance and effectiveness of these measures or facility design f) Demonstrate compliance with licence conditions, or collect evidence for regulatory purposes g) Identify and characterise discrete aquifer water bodies.
