Hotspot analysis to contribute to a cleaner Meuse river (Part 2)

With our team of Technical University of Delft students, we continue our collaboration with Schone Maaswaterketen – a collaboration between Rijkswaterstaat, the Ministry of Infrastructure and Water Management, Dutch water boards and water companies. Their goal is to make the Meuse basin cleaner by reducing pollution.

Hydrex Research Center is managing this team of talented Technical University of Delft students as they continue improving and extending the comprehensive database that was set up in the first part of our collaboration. With more available data and input from the Dutch water boards, Rijkswaterstaat, and the drinking water companies, the database can be focused on the key factors that are needed to take effective action to prevent further pollution of the Meuse Basin.


The database functions as a tool in which the Schoon Maaswaterketen can identify hotspots of pollution inside the Meuse Basin. It enables the water boards to make a better informed decision regarding the discharge permits they provide. In the second part of this project, the tool is updated with new pollution categories and additional regions.


A better risk classification is created by adding a PMT (Persistence, Mobility and Toxicity) score to each substance which gives a more representative image of how harmful a substance actually is. With the expertise of the Schoon Maaswaterketen members, the fresh insightfulness of our students, and the shared goal of a clean Meuse, the database is efficiently tweaked to the needs of its future users.


The Meuse basin flows through the provinces of Brabant and Limburg. Connected to this basin are sewage treatments that have to deal with the polluted discharge of the companies connected to these treatment plants. Currently, the water boards encounter challenges in linking water pollutants to their respective geographical areas and associated companies, as this information is fragmented across various sources.


To address this issue, our team connects existing knowledge related to these companies, their specific pollution profiles, and geographical locations. By compiling a comprehensive yet user-friendly database, we aim to provide the Schone Maaswaterketen with a reliable resource for informed decision-making regarding discharge permits.
