Digital Twin II

In this project a so-called ‘digital twin’ of a drinking water distribution network of a Dutch city is being made, with the aim of determining the impact of corona measures – lockdown and increased working-from-home – and…

Emerging contaminants

Non-target screening

The steady growth in the production and use of chemicals is leading to an increased presence of these compounds in drinking water and drinking water sources. Target screening is no longer sufficient for the monitoring of all…
