RAG Aktiengesellschaft, Essen\/Germany, has been monitoring the groundwater in the area of the Brinkfortsheide spoil tip since mid-2020 (Figure 1). A pumping test is now starting to plan a groundwater treatment plant.<\/p>\n
Ten of the 13 additional groundwater measuring points planned have already been sunk and integrated into the monitoring system. All of them are in the south-western and north-western part of the spoil tip because this is where the groundwater flows under the spoil tip body from east to west. The last three were completed by the end of February 2025. The results of the measurements will be sent to the district government as agreed.<\/p>\n
In addition, a pumping test of the groundwater will be carried out to determine the hydraulic design data for the planning of a future stationary groundwater treatment plant. During the three-month pumping test, the groundwater will be cleaned in a mobile treatment plant and then fed into the municipal sewer.<\/p>\n
The measure has been agreed and approved by both the district government and the city of Marl.<\/p>\n
