COVID-19: Wastewater Testing Data
People infected with the virus that causes COVID-19 may shed it in the water that flows from their homes to public wastewater systems. This happens whether they have symptoms or not. Communities can track virus activity by looking for viral RNA in wastewater. Wastewater, or sewage, includes water that may contain human waste (toilets, showers, sinks). It also includes water from some other sources (rainwater, water for industrial use). To better understand the burden of COVID-19 in a community, Maine CDC and U.S. CDC test wastewater for the virus. This helps to tailor public health actions to protect communities across the state.

Maine CDC oversees a COVID-19 wastewater testing program at 16 sites across Maine, and U.S. CDC oversees a COVID-19 wastewater testing program at eight additional sites in Maine. For additional data visualizations, visit Biobot COVID-19 Wastewater Monitoring.
