The graph with the green dots and error bars represent the North System The graph with the orange dots and error bars represent the South System View graphs here (PDF). View the data behind the graphs here (PDF). The data tables include some variant screening results as provided by Biobot Analytics. Additional information regarding the presence of SARS-CoV-2 genetic material in wastewater is available from EPA and CDC . MWRA is now submitting samples for additional disease targets to the WastewaterSCAN program in addition to our regular testing with Biobot Analytics. View LIVE WastewaterSCAN results
