Recent sampling missions for water quality analysis

As part of PUSH IT’s Work Package Task 3.3, focused on microbiology and heavily involving our PhD student Maud Watkinson, BRGM has conducted several sampling missions over the past two months.

  • Delft: Collected sediment cores and water samples during the drilling period early April.
  • Berlin Adlershof: Collected water samples and rock samples from sediment cores at the ATES site at the end of April.
  • Darmstadt: Started sampling several months ago to characterize microbial diversity in the water.

The aim of the samplings in Delft and Berlin is to simulate water, rock and microorganism interactions with temperature variations in the laboratory, using experimental batches or percolation cells. 

In parallel, geochemical simulations are currently being conducted based on monitoring results to investigate potential geochemical changes and discuss their operational implications.

Investigating microbial diversity in Berlin’s groundwater

PUSH-IT partners Sétareh Rad and Maud Watkinson from BGRM visited the ATES site in Berlin Adlershof and successfully completed sampling for microbial diversity in shallow groundwater layers.

They collected water from a 60-meter-deep well near the research well. This allows us to establish a baseline of microbial diversity, making it possible to compare it with future data after the hot push-pull tests or the initial seasonal storage loading.
