COVID-19 Wastewater Concentration Dashboard
Pathogen: Sars-CoV-2
The New York State Wastewater Surveillance Network Dashboard reports levels of viruses and other pathogens in untreated sewage entering wastewater treatment plants in New York State. This testing can be a reliable indicator that certain infectious diseases are circulating in communities.
Wastewater surveillance is an important tool for tracking the spread of COVID-19. Testing wastewater can detect the SARS-CoV-2 in wastewater before we see increases in the percentages of people who test positive for COVID-19.
Data on the New York State Dashboard may differ from CDC’s COVID wastewater surveillance tracker. View the Wastewater Surveillance Methodological Notes for more information about how New York State and the CDC report their data.
About the New York State Wastewater Surveillance Network
New York State Department of Health’s Center for Environmental Health and Wadsworth Center Laboratory lead the Water Surveillance Network in partnership with Syracuse University. Other partners include University at Buffalo, Stony Brook University, SUNY College of Environmental Science and Forestry, Genesee and Orleans Departments of Health, University at Rochester, New York Medical College, SUNY Upstate Medical University, Quadrant Viral Testing, and New York City Department of Health and Mental Hygiene.

Statewide Participation Summary
Map of Participating Treatment Plants and Counties
SARS-CoV-2 level – View categories of SARs-CoV-2 levels by sewershed. Results are shown as low, moderate, high, and very high levels based on the amount of virus detected in wastewater. NA means data were not reported for those sewersheds.
*Additional details on SARS-CoV-2 levels and the case incidence that correlates with each level can be found in the Current Methods section of the methodological notes.
Two-week Trend - View how SARS-CoV-2 levels are increasing, decreasing, or stable over the most recent two-week time period. This is calculated by comparing the most recent samples with the those taken 14-days prior. The percentages of increasing or decreasing concentrations are displayed by color on the map and legend. Sites with fewer than two samples within the 14-days period appear as NA (grey).
SARs-CoV-2 Wastewater Trend Over Time
SARS-CoV-2 RNA Gene Copies Detection Trend
Select your County, Lab Method, and Date Range to view the SARS-CoV2 RNA gene copies in wastewater by calendar week. Reset the Date Range using the small button that appears in the top right corner when you hover over the “Date Range” box.
Results show the average number of SARS-CoV-2 RNA gene copies by calendar week and trendlines for data from each sampling location within a selected county or New York State. Population weighted average of all locations within the selected county or New York State are displayed by the dashed line.
Dropdown menus allow you to view data from a specific county or New York State based on laboratory methods used to analyze samples. “Current” and “Historical” lab methods are plotted separately because laboratory methods vary greatly and should not be directly compared to one another. The “Current” lab method shows all samples collected under our current lab protocol in place since January 2025*. The “Historical” lab method shows all data collected under previously used lab protocols (see methodological notes). Note, not all sampling locations have both current and historical data.
*While NYC counties (Bronx, Queens, Kings, Richmond, New York) and Long Island counties (Nassau and Suffolk) both have “current” lab method data, these two groups of counties each use a different method from the remainder of New York State.
