A watershed moment in public health
Our approach to wastewater-based epidemiology (WBE) monitors the spread of pathogens to help communities prepare for and prevent the spread of infectious diseases.

Wastewater-based epidemiology (WBE)
Verily is a leader in the laboratory science behind wastewater-based epidemiology. In collaboration with scientific organizations, government agencies, and commercial organizations, our scientists conduct research to develop and validate assays needed to consistently and accurately measure the concentration of viral and bacterial DNA and RNA for a variety of pathogens in wastewater in near real time — providing information about levels of disease spread within communities.
Verily is working closely with public health specialists, clinicians, and researchers to use the data from wastewater to explore various use cases ranging from improving existing public health surveillance systems to optimizing research and development efforts.
Our approach
Verily’s researchers are on the leading edge of identifying pathogens of public health importance that can be detected in wastewater.
What we measure
Verily has currently implemented assays to test for 30 pathogens and are conducting research and development into several more. We work with our partners to identify pathogens of interest and develop approaches to monitor these in wastewater.

Verily works with our clients to collect samples from a variety of locations throughout the wastewater system–from treatment plants representing millions of people to pipes accessed by manholes for specific facilities and institutions.
Samples can be either liquid influent or settled solids from a primary clarifier
Verily provides sample collection training and all materials for collecting and shipping samples back to our lab
The Verily difference
Verily provides quality, fast turnaround wastewater monitoring results for a broad array of pathogens to hundreds of sites across the United States using our high-throughput, state-of-the-art lab leveraging automation to optimize efficiency.

A watershed moment
Hear from public health officials about real-time wastewater monitoring to help protect the Las Vegas community, in Verily’s short documentary series N of 1.
Monitoring the health of communities
The detection and quantification of pathogens through wastewater can provide advanced warning, before clinical testing or hospitalizations regardless of access to and availability of health services, and at a very low cost compared to individual clinical testing.
Verily provides an easy to understand online tool to monitor the level of viruses circulating in the geographic areas from which samples are submitted. With the right data, at precisely the right time, public health officials can make better-informed decisions about how to distribute resources and support our communities.
