The management of separate groundwater contamination plumes focuses on quality assessment and, when necessary, remediation. This management of groundwater plumes in the Netherlands is often problematic for technical, practical or financial reasons. One solution is a tendency towards not managing groundwater plumes individually, but from an integrated perspective and on a larger scale. This so-called region-specific groundwater management is often more efficient and hence, cheaper. The reason for this is that groundwater quality assessment within the specific region is less stringent than in individual cases of groundwater contamination. Moreover, the organisation of the management of a cluster of groundwater plumes is much easier than it would be if all individual groundwater plumes were managed at different points in time. Region-specific groundwater management should follow a tailor-made approach. However, to facilitate region-specific groundwater management, the Dutch Ministry of Infrastructure and the Environment commissioned the National Institute of Public Health and the Environment (RIVM) to formulate some practical guidance. This guidance relates to the delineation of the domain, the management of sources for groundwater contamination, procedures for monitoring, (risk-based) assessment of the groundwater quality and a cost-benefit analysis. This information is supplementary to other relevant documents, for example, the Practical Guide for region-specific groundwater management (in Dutch, Handreiking gebiedsgericht grondwaterbeheer) which was also drawn up by order of the Ministry of Infrastructure and the Environment.
