The college of Dinkelland must look for answers to questions about the injection wells that are asked by the municipal council. The CDA, Lokaal Dinkelland and GroenLinks want to know more about the damage to the ROW2 injection well. Earlier this week, the Nederlandse Aardolie Maatschappij discovered a crack in the well, which significantly increased the risk of wastewater leakage.
The NAM denies a possible leak and says that this would have been noticed in the monitoring. However, the same argument has always been said that there would be no crack in the tube. This should have become apparent from the pressure measurements in the pipe.
The NAM only discovered the damage when the inner pipe was pulled out of the well, so that the entire outer pipe could be scanned with measuring equipment. In a normal situation, such an extensive scan in a double-walled tube is not possible. That is why it is unclear how long the crack has been there. NAM conducts extensive research and the State Supervision of Mines controls that investigation.
The news about the damage to the injection well on the Tramweg in Rossum makes people in the area think. GroenLinks, the CDA and Lokaal Dinkelland have received these signals and are asking questions to the mayor and aldermen.
Can this damage also occur in other injection wells?
They want to know if this damage could also occur in other wells. Well ROW2 dates from 1955 and the other wells in the municipalities were built around 1960/70. The steel outer pipes in all those wells are at least 50 years old. The parties believe that the NAM should stop injecting immediately, now that it has become apparent that there is an increased risk of leakage.
In fact, the College of Dinkelland can only contact NAM to answer the questions. The petroleum company has all the information and conducts its own investigation. The State Supervision of Mines must also make do with this. The municipality has no powers in mining and can only ask the Minister of Economic Affairs to intervene. That is what CDA, GroenLinks and Lokaal Dinkelland have now also asked for.
Questions are also asked in the Provincial Council. Member of Parliament Robert Jansen wants the injection wells to be closed for detailed inspection. The Stop Afvalwater Twente foundation, which has been advocating since 2014 for the purification of waste water for reuse instead of discharge into the soil. Comedian Herman Finkers wrote a song about it in 2017: Vot met den prutt’l.
