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. You can click and drag on an area of the graph to zoom in, and click on series in the legend to turn them off and on.

Framingham is in the South region with about 20 other communities including Ashland, Natick, Wellesley, Needham, and portions of Newton, Brookline, and Boston.

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

Note: Biobot, the external private lab running the testing, announced a change to its data processing protocol during this project. The graph below reflects the new protocols, but does not include confidence intervals and error bars now available. Please go to the MWRA site to see those.
