This page displays data on the amount of SARS-CoV-2 in Umeå and Örebro wastewater between October 2020 and June 2021. After June 2021, a new method is used for analyses of wastewater, and the most recent data can be found here.
The data displayed here were collected as part of a research project led by associate professor Maja Malmberg (SLU, Swedish University of Agricultural Sciences; maja.malmberg@slu.se) in collaboration with the SciLifeLab COVID-19 National Research Program and associate professor Mette Myrmel at the Norwegian University of Life Sciences. The amount of SARS-CoV-2 virus in the wastewater of Umeå is measured using samples taken from the wastewater treatment facilities in Umeå and Örebro. Please consult this map for the exact catchment area of the wastewater collection channels in Umeå.

After preparation, the viruses were extracted using ultra filtration and analyzed using qPCR technique for SARS CoV-2 RNA. Primers were used to detect the SARS-COV-2 gene (previously used and verified by Corman and colleagues (2020)). qPCR samples were normalized against PMMV. Until January 2021, three samples per week were taken and their results were pooled to provide a weekly estimate. From February 2021, samples were instead collected weekly.
In the plots plots below, the amount of SARS-CoV-2 for each week is measured/depicted compared to the amount of SARS-CoV-2 on 6th November 2020.
