What is wastewater testing for COVID-19?

CSU, in coordination with CDPHE and LCDHE works to identify COVID-19 viral levels in wastewater coming from businesses and places of residence.

"Wastewater" is the sewage or dirty water from homes and buildings that gets sent to a wastewater treatment plant. Wastewater includes water and anything that goes down a toilet or drain inside a home or other building. A "sewershed" is an area that collects wastewater. In Larimer County, small sewersheds throughout the county are monitored in order to detect whether COVID-19 is present in specific areas of the community.

Many people who have COVID-19 also shed the virus in their stool (poop). Traces of the virus can be detected in poop up to a week before someone starts to have symptoms of COVID-19. This means that wastewater can serve as an early warning signal that COVID-19 is present in a specific community or neighborhood.

How does wastewater testing help slow the spread of COVID-19 in Larimer County?

Wastewater testing is another tool we have available to reduce the transmission of COVID-19 in our community. By adding wastewater monitoring to Larimer County’s individual testing we can respond quickly and inform residents to minimize community spread, if needed.
