The SARS-Cov-2 sewage water samples of 20 August in Netherlands

Since the end of February, KWR has been monitoring concentrations of the genetic material of the coronavirus, so-called SARS-COV-2 RNA, in the sewage water in seven cities, at Schiphol Airport and in Terschelling. The concentration is a measure of the infection rate among the population that is connected to the analysed sewage system. The KWR microbiologists were one of the first research groups in the world to publish their research method, so that colleagues in other countries could also monitor sewage water in a standardised fashion. This page presents the current analysis of the sewage water samples collected on Thursday, 20 August. We do not observe any great shifts in Amsterdam, Utrecht, Amersfoort, Tilburg, Schiphol or Franeker. Rotterdam, in turn, shows an increase for the second week in a row. In Apeldoorn, a signal can again be observed for the first time after a long period, and Terschelling has again fallen below the detection limit. We did not receive any monitoring data for The Hague.
