Wastewater Testing

Monitor the spread of COVID-19 and detect outbreaks early in your state, community, or region.

To assess the spread of COVID-19 in their communities, state and local leaders need timely and accurate data. Diagnostic and serological testing of individuals remains critical, but these tests don’t provide continuous updates on the presence and extent of viral infections for the local population. Fortunately, states and municipalities have another information source: their wastewater. With more than 14,000 wastewater treatment plants around the country already collecting samples to detect pollutants in sewage and storm runoff, many municipalities already have the infrastructure in place to conduct rapid, repeated, communitywide viral testing. This is where our experts come in to coordinate and scale testing while synthesizing and visualizing results to drive a data-driven response.

The value of comprehensive, rapid, and scalable testing coverage for informed policymaking is unmatched.

The Power of a Single Test

Testing wastewater samples means a single test can detect the presence of viral debris from SARS -CoV –2 (the cause of COVID-19) in an area, and with our back-end statistical analysis techniques, can estimate the exposure of more than 10,000 people in a town or city. Samples can be collected daily with test results typically available in less than a week, providing public officials with quick and continuous updates on the spread of COVID-19 in their communities. Although labs only recently began piloting the use of wastewater testing to detect COVID-19, the same approach has been successfully implemented to manage past outbreaks of tuberculosis, measles, and polio outside the United States.
