<unk>  is the process of monitoring<unk>  for contaminants. Amongst other uses, it can be used for biosurveillance, to detect the presence of pathogens in local populations, and to detect the presence of psychoactive drugs. One example of this is the use of<unk>  monitoring to detect the presence of the SARS-CoV-2 virus in populations during the COVID-19 pandemic. In one study,<unk>  showed signs of SARS-CoV-2 RNA before any cases were detected in the local population. Later in the pandemic,<unk>  was demonstrated to be one technique to detect SARS-CoV-2 variants and to monitor their spread in regions for studying related ongoing infection dynamics.
