MWRA's wastewater testing detects virus levels in sewage and offers a way to detect Covid-19 infection trends before testing of individuals.
Only communities in eastern Mass that are part of the MWRA sewage systems are included. To see additional testing data, go to the Massachusetts Wastewater Surveillance website
Most of this data come from the Massachusetts Department of Public Health Web site and the City of Framingham Web site. MWRA wastewater testing comes from the pilot project with Biobot; more info and raw data available from the MWRA.

This application was created by Sharon Machlis with the R programming language and several R packages including shiny, data.table, ggplot2, plotly, leaflet, DT, and glue, among others. It wouldn't have been possible without the incredible contributions of the R core team and R package authors to make this free platform possible. (Any and all errors in the data presentation are, however, mine alone.)
