Witteveen+Bos wins De Vernufteling 2025 with ‘eDNA Meets Toxicity’
Yesterday, eDNA Meets Toxicity won both the jury and the people’s choice prizes for De Vernufteling 2025. It was the twentieth time that Koninklijke NLingenieurs presented the award to the most innovative engineering project of the year. Our pioneering measurement technique analyses eDNA – environmental DNA – to determine toxicity levels in water.
The data this results in allows us to better understand biodiversity loss and determine the influence toxic substances have on it. With this knowledge, we can then apply the necessary measures to improve water quality.
eDNA Meets Toxicity is a revolutionary breakthrough in combating biodiversity loss, all the more so because it can also be applied in domains other than water, such as soil and air.
Jury chairperson Anne Schroën: ‘We were looking for a project that wasn’t just technically excellent but also had a clear impact on our society and economy. Witteveen+Bos’s method is faster, cheaper and more reliable than the traditional method, and it can be used in a wider range of scenarios. The jury is very impressed that Witteveen+Bos has embraced eDNA technology and incorporated it into a solution that is current and demonstrates courage and collaboration.’

Sebastiaan Schep, aquatic ecologist at Witteveen+Bos and initiator of eDNA Meets Toxicity: ‘It’s a huge honour to win De Vernufteling. But more importantly, it’s fantastic that the jury and the public recognised the importance and potential of our innovation. This recognition also provides a great impetus to unlock the full potential of eDNA Meets Toxicity as quickly as possible.’
In developing eDNA Meets Toxicity, Witteveen+Bos was supported by:
The water authorities Aa en Maas, Brabantse Delta, Delfland, Drents Overijsselse Delta, Hollands Noorderkwartier, Hollandse Delta, Rijnland, Rivierenland, de Stichtse Rijnlanden, and Vechtstromen, as well as Datura, KWR, Microlan, the Ministry of Infrastructure and Water Management, the Province of South Holland, RIVM, STOWA, the University of Amsterdam, Het Waterlaboratorium, and Waternet.
