COVID-19 viral loads in wastewater are up in North Battleford, Sask., but down in Saskatoon, the most recent data from the University of Saskatchewan shows. Since the summer of 2020, a group of researchers from the U of S have analyzed wastewater samples from Saskatoon, North Battleford and Prince Albert in search of traces of the COVID-19 virus. However, data is not available from Prince Albert this week because researchers only received one sample from the city's wastewater, which was delivered late, according to an email from wastewater project manager Femi Oloye.
