This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Wastewater based surveillance employing qPCR has already shown its utility for monitoring SARS-CoV-2 at community level, and consequently the European Commission has recommended the implementation of an EU Sewage Sentinel System. However, using sequencing for the determination of genomic variants in wastewater is not fully established yet. Therefore, we focused on the sequencing analysis of SARS-CoV-2 RNA in wastewater samples collected across 20 European countries including 54 municipalities. The results provide insight into the abundance and the profile of the mutations associated with the variants of concerns B.1.1.7, P.1, B.1.351 and B.1.617.2, which were present in various wastewater samples. This study shows that integrating genomic and wastewater-based epidemiology (WBE) can support the identification of variants circulating in a city at community level.
