The Geological Survey of the Netherlands (GDN) collected data on pollution under Dutch ground, according to Innovation Origins. 

The data is being made available to the public starting this week.

The data provides an overview of the various types of groundwater pollution which is especially useful for companies, governments, citizens, and farmers. 

The Dutch website intends to provide users with information about elements in soil, such as aluminum, arsenic, and ammonium.

According to the GDN, the data refers to groundwater lying not just below ground level but much deeper, approximately more than 50 meters below the surface. 

“Insight is gained into groundwater quality by cleverly combining a variety of data. And this reaches into the deepest levels of Dutch groundwater,” said Michiel van der Meulen, head of mapping at GDN.

Currently, the data is predominantly information from the Rivierenland area and the south of the Netherlands, but the hope is to expand the quantity of data over the next few years. The ultimate goal would be to offer nationwide coverage, according to GDN.

According to Van Der Meulen, installers of ground-based energy systems can estimate the redox state of the groundwater in advance, avoiding potential blockage problems in the infiltration wells. Regional and national authorities can also use the data to evaluate and identify strategic water and groundwater resources resulting from the Dutch Subsoil Structure Vision scheme (STRONG).

Additionally, the information can be used by water suppliers to correlate the composition of water in their wells with groundwater quality data from extraction sites, as well as to link this to the geological structure of the subsurface, reported Innovation Origins.
