Which technological tools would be needed to implement the sewage surveillance as standard method in situ?

The method used for virus detection is called RT-qPCR (Reverse transcriptase quantitative polymerase chain reaction). This is the same method as is used to detect SARS-CoV-2 in patients. In this method, the RNA fragments (genes from the virus) are detected confirming the presence of SARS-CoV-2. Therefore, the method cannot be performed in situ. However, microbiologists from KWR are working on alternative methods for in situ detection in wastewater.
