van Beem, Nathan (author), Dijkstra, M.M. (author), Egelmeers, Eva (author), Kraan, Tejon (author), Yang, Y. (author)Only 1% of the surface water in the Netherlands has been classified as ‘good’, making it the EU member state with the worst quality of surface water (Didde, 2022). Polluted rivers cause problems such as worsened human health, reduced biodiversity, and poor soil fertility. To comply with the Water Framework Directive, there is an urgent need to...student report 2024

Middelbeek, Lisanne (author)This research addresses the issue of rising soil temperatures, driven by climate change. As the Drinking Water Distribution System (DWDS) is located in the sub-surface, the drinking water temperature in the distribution mains attains this rising soil temperature. Because the temperature of drinking water is an important determinant of water...master thesis 2024

(author), Wegman, Carolien (author), Vriend, Paul (author), Boon, Anouk (author), de Winter, Winnie (author), Uijlenhoet, R. (author)Rivers are one of the main conduits that deliver plastic from land into the sea, and also act as reservoirs for plastic retention. Yet, our understanding of the extent of river exposure to plastic pollution remains limited. In particular, there has been no comprehensive quantification of the contributions from different river compartments,...journal article 2024

(author)Escherichia coli (E. coli) plays a central role as an indicator for fecal contamination to predict the possible presence of microbial pathogens in drinking water. Current detection methods for E. coli are based on time-consuming culture-based techniques. There is a strong need for methods to detect fecal contamination rapidly in distributed...journal article 2024

Ernste, Daniël (author)In this study, the relationship between water quality and agriculture in the upstream region of the Brantas catchment has been investigated, with a focus on Electric Conductivity (EC), Dissolved Oxygen (DO), pH, nitrate, Biological Oxygen Demand (BOD), phosphate and ammonia concentrations. The EC concentrations ranged from 120 to 570 μS/cm, the...master thesis 2023

Frey, Veronika (author), Kraaijvanger, Joost (author), Lorenzen da Silva, Valentin (author), Oudenes, Derby (author)In this project, student teams from Universidad San Francisco de Quito and Delft University of Technology worked together to provide safe drinking water in Ecuador. We used M-100 chlorinators from the company WaterStep, donated by Water Ambassadors Canada, to chlorinate water in schools and communities. The journey involved testing water quality...student report 2023

Dommerholt, Naomi (author)This study investigates the connection between macro-scale parameters (MSP) and micro-scale water quality parameters (MSWQP) in the Brantas River, employing a multivariate linear regression (MLR) modelling approach. The analysis reveals several critical insights into the complex dynamics of water quality in this river system.<br/><br/>Key...master thesis 2023

Pasdar Yazd, Baahar (author)Netherlands urban canals are not designated as official bathing sites for recreation, and their water quality is not monitored routinely. The municipality of Breda has ambitious plans to ensure the recreational water quality in the Breda canals during the bathing season. <br/><br/>The purpose of this study was investigation of microbial water...master thesis 2023

Eisfeld, R.C.M. (author)Fresh water is an essential resource for life. Yet, overexploitation of water resources, rainfall shortages, and a decrease in water quality by pollution increase water scarcity worldwide. Since agricultural production consumes about 70% of the available fresh water resources, it is particularly vulnerable for water scarcity. Therefore, this...doctoral thesis 2023

van Egmond, Jessie Lynn (author)For this thesis a hydrochemical groundwater survey was carried out on the Caribbean island of Curaçao in 2020 as part of the NWO SEALINK project. In order to be well-adapted against anthropogenic and natural pressures, Curaçao needs representative data, yet thorough hydrochemical datasets were only sparsely collected in the wet seasons of 1977...master thesis 2023

Pronk, Tessa E. (author), Fischer, A. (author), van den Berg, Annemijne E.T. (author), Hofman, Roberta C.H.M. (author)A main focus of water managers with regard to micropollutants is the protection of aquatic ecology. However, micropollutants also have the potential to affect the production of clean drinking water. In this paper, we propose to consider the removal effort when assessing micro-pollutants with an ‘Effort Index’ (EI). Assessments using the EI...journal article 2023

Kim, J. (author), Jonoski, Andreja (author), Solomatine, D.P. (author), Goethals, Peter L. M. (author)Flow control flushing water from reservoirs has been imposed in South Korea for mitigating harmful cyanobacterial blooms (CyanoHABs) in rivers. This measure, however, can cause water shortage in reservoirs, as the measure adopting this flow control may require an additional amount of water which exceeds the water demand allocated to the...journal article 2023
