What’s the future of wastewater testing for COVID‑19?
Wastewater surveillance became an important tool for detecting COVID-19 outbreaks in communities throughout the pandemic, and it continues to be used in search for coronavirus SARS-CoV-2 as well as other pathogens.
But it’s unclear whether current levels of government funding to monitor wastewater for SARS-CoV-2 will continue beyond next year. Experts are calling on the federal government to create a standardized system for wastewater surveillance to bolster and replace the patchwork being used today.

New research examines wastewater to detect community spread of Covid-19
A series of crucial setbacks in Covid-19 testing has made it difficult to keep up with the virus’ rapid spread, and has inspired some researchers to look to wastewater to help fill in the gap of measuring how prevalent SARS-CoV-2 is in a given community.
In a paper posted Tuesday to the preprint server medRxiv, researchers collected samples in late March from a wastewater treatment plant serving a large metropolitan area in Massachusetts and found that the amount of SARS-CoV-2 particles in the sewage samples indicated a far higher number of people likely infected with Covid-19 than the reported cases in that area.
