Between July 21, 2020 and October 21, 2020, the Greater Augusta Utility District sampled its wastewater from 5 Maine communities (Augusta, Hallowell, Manchester, Monmouth, Winthrop) for the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) , the virus that causes COVID19 disease.
Biobot is analyzing the samples and reporting the results. Review results below.
The particular testing performed on the District's untreated wastewater will detect RNA from the SARS-CoV-2 virus.
