A groundwater body (GWL) is as defined in the Water Framework Directive (WFD): a separate groundwater mass with an unambiguously defined chemical and quantitative status. The WFD has several options for how groundwater bodies are delimited. In the Netherlands, use is made of the geological structure of groundwater bodies, groundwater flow and administrative boundaries.
Due to the absence of geological barriers, the various groundwater bodies in the various sub-basins are large in size.
It should be possible to allocate each GWL to a (1) river basin and it should be clear per GWL whether the objectives of the WFD can be achieved.
There are two groundwater bodies in Overijssel.
A groundwater body with a coating (Rhine-East NLGW0010) and a sand-groundwater body without a coating (Rhine-East NLGW0003).
The two groundwater bodies are subject to threshold values and Community standards for groundwater quality.
Groundwater quantity standards also apply.
