Online sensors have been installed by UIT (Umwelt- und Ingenieurtechnik GmbH Dresden) at the Water Works in Berlin-Spandau. Three recorders are now measuring water level and water temperature and transfer the data by GPRS – telemetry. This data is now used in the INOWAS platform to assess hydraulic characteristics of the site and to combine site-specific properties with other evaluation software, such as numerical modelling and microbial risks assessment.

Automatic flow cytometer for microbiological monitoring was tested at the Water Works in Berlin-Spandau. A continuously flowing sampling line was installed to measure the microbial fingerprint during a groundwater transcect at an infiltration basin, observation well and an abstraction well. The device (Sigrist BactoSense) was operated with sampling interval of 6 h and gives new insights in the temporal and spatial variations of microbial communities present in the subsurface.
