Monitoring and analysis

The monitoring and analysis of bacteria and viruses present in different water sources helps to indicate the presence of COVID-19 in wastewater in specific regions. The outcomes also provide useful information for policy makers. In the Netherlands technology companies and knowledge institutes are essential in the development and improvement of such monitoring and analysis technologies.

Nationwide COVID-19 sewage water surveillance system now in place – September 2020

The collective sewage water of all inhabitants in the Netherlands, i.e.17 million people, is now being monitored on the presence of Covid-19.
