Groundwater quantity wells

Description

Under the Groundwater Act, the province of Zuid-Holland is obliged to establish, maintain and monitor a groundwater monitoring network. The aim of this monitoring network is to monitor regional changes in the water system. The provincial groundwater monitoring network consists of a system of primary monitoring wells (provided by the province), supplemented by secondary and tertiary monitoring wells that come from monitoring networks of others (such as water companies, municipalities or nature managers) or from temporary monitoring networks (e.g. well drainage). The groundwater monitoring network of the province of Zuid-Holland consists of approximately 260 quantity wells in which the groundwater level is measured and 52 quality wells in which the groundwater quality is determined. In each measuring well there are one or more level filters at different depths. The number of filters per well and the depth at which the filters are located differs per measuring well and depends on the structure of the subsurface at the location where the well is located. A measurement takes place every 14 days in all measuring wells. This measurement is carried out automatically by means of a ‘diver’, or by an observer. In addition to the permanent observer of the province, there are several private individuals who observe one or two measuring wells on their site. The monitoring and maintenance of the groundwater measuring wells is done in collaboration with TNO NITG. They process the measurement data and store it in a database (DINO: Data and Information Dutch Subsurface). Data, such as groundwater levels, can be retrieved from this database via the internet. With the help of the data from the groundwater monitoring network, insight can be gained into the height of the groundwater levels and the groundwater quality (and the changes therein) within the province of Zuid-Holland. This information can be used, for example, in new construction projects, the construction of nature reserves or in solving problems with groundwater (such as groundwater nuisance). In the coming years, we will look at whether there is a need for other information from the groundwater monitoring network than can now be requested via the DINO database and how this information should be made available.
