MWRA Wastewater Covid-19 Tracking

MWRA's wastewater testing detects virus levels in sewage and offers a way to detect Covid-19 infection trends before testing of individuals. Note: You can click and drag on an area of the first graph to zoom in, and click on series in the legend to turn them off and on.

Only communities in eastern Mass that are part of the MWRA sewage systems are included. To see additional MWRA testing data, go to the Massachusetts Water Resources Authority website
