When extracting oil in Schoonebeek, the waste water must be injected as close as possible into the ground. That is what the Vechtstromen Water Board says in an urgent advice to State Secretary Hans Vijlbrief of Mining. The choice of where the waste pits should be located is left to the Nederlandse Aardolie Maatschappij (NAM).
The water board has been asked by Vijlbrief to respond to the final report ‘Reassessment of processing production water Schoonebeek 2022’ that NAM published in June. In addition to keeping the transport distance as short as possible, Vechtstromen also advises to reduce the risk of contamination of groundwater and surface water by ‘extensive purification of the production water using the best available techniques’. The water board also calls for proper monitoring of the pipes and installations used.
At the beginning of this month, the Ministry of Economic Affairs and Climate (EZK) announced that it had asked NAM not to start oil extraction in Schoonebeek for the time being. This is to provide clarity to the inhabitants of Twente, where the wastewater has so far been injected into the ground. Oil extraction has been halted for months after wastewater from the extraction contained too much of the chemical toluene.
