Whatever your subsurface question, DINOloket is happy to help you get started. Our portal offers a wealth of information with lots of data and subsurface models. As the developers of DINOloket, the Geological Survey of the Netherlands, we also have a lot of subsurface knowledge and expertise in-house.
If you are not an expert and are looking for certain subsurface information, we have some tips.
For example, do you want to know more about the subsurface of your house or garden because you want to make a well or install a borehole thermal energy storage system?
First check with your municipality/province (borehole thermal energy) or water board (constructing a water well) under which legal conditions it is allowed to extract groundwater. Each municipality/province and water board have specific rules on what is allowed. So, the reasons why something is or is not allowed may vary per region or even per location. Next, make sure you work with a certified drilling company in the region to carry out the drilling. They know the subsoil and carry out their work according to the applicable standards and guidelines and also know what conditions the construction has to meet.
The Geological Survey of the Netherlands, part of TNO, has information of the subsurface, such as here on DINOloket. So, you can retrieve all information about subsurface structure and groundwater quality at subsurface data. This allows you to get an indication of the local subsurface conditions of the local subsurface. Practical information for using DINOloket can be found at Help. You can also get an idea of the groundwater quality at ‘Grondwaterstanden in beeld’ on our site www.grondwatertools.nl. It is also important to realize that our subsurface models have a regional character. It gives an indication (probability) of what the structure of the subsurface is at a specific location. You can read more about this on the explanatory pages of the subsurface models. Sometimes local information, for example in the form of data from a borehole, is available, which gives a further indication. So, what the subsoil under your house looks like, for example, cannot be determined exactly with this.
The rather complex structure of the Dutch subsurface requires specific expertise for the use and interpretation of subsurface data and models. Various dedicated consultancy companies can do that for you. The Geological Survey of the Netherlands mainly carries out applied research and ensures that subsurface data is available.
