Test results from MWRA’s pilot study to track wastewater at the Deer Island Treatment Plant for indicators of COVID-19 infection will be posted on this site.
Samples are currently taken 3 times a week and data are updated as received by our contract laboratory, Biobot Analytics.

The data are shared with staff from the Departments of Public Health and Environmental Protection, and the Executive Offices of Health and Human Services, and Energy and Environment.
It is important to note that this is a pilot of an evolving science. The results from this study will be used public health officials as additional tool for the Commonwealth to track how the pandemic is trending in Massachusetts, along with data from clinical tests, hospitalizations, etc. All the data, taken together, will be used by state officials to make decisions about how quickly respond.
Please refer to the Mass DPH website for information regarding current cases of COVID-19 in your community.
