This part of ISO 5667 provides guidance on the sampling of groundwater at potentially contaminated sites. It is applicable to situations where contamination of the subsurface could exist as a result of downward migration of pollutants whose source is at the surface or just below it, and when the guidance provided in ISO 5667-11 is inappropriate.
