DIN ISO 18400-203:2020-11

This document gives guidance on the: — investigation of sites, where either it is known that soil contamination is present, or the presence of soil contamination is suspected; — investigation of sites where no soil contamination is expected, but the soil quality is to be determined (e.g. to make sure that there is no contamination present); — investigation in anticipation of a need to manage re-use or disposal of excavated soil which might be contaminated; — collection of information that is necessary for risk assessment and/or the development of remedial action plans (e.g. whether remediation is required and suggestions as to how this might be best achieved).
