Broers, H.P. (author), Sultenfuss, J. (author), Aeschbach, W. (author), Kersting, A. (author), Menkovich, A. (author), de Weert, J. (author), Castelijns, J. (author)Knowing the age distribution of water abstracted from public water supply wells helps to ensure customer trust in drinking water sources and underpin predictions of water quality evolution. We sampled the mixed water of 39 large public supply well fields for major ion chemistry, 3 H, 3 He, 18O, 2 H, 14CDIC, 13CDIC and noble gases and determined...article 2021

Mehrtens, A. (author), Licha, T. (author), Broers, H.P. (author), Burke, V. (author)The purpose of this long-term experiment was on gaining more insights into the environmental behaviour of veterinary antibiotics in the subsurface after application with manure. Therefore, manure spiked with a bromide tracer and eight antibiotics (enrofloxacin, lincomycin, sulfadiazine, sulfamethazine, tetracycline, tiamulin, tilmicosin and...article 2020

Yu, L. (author), Rozemeijer, J.C. (author), van der Velde, Y. (author), van Breukelen, B.M. (author), Ouboter, M. (author), Broers, H.P. (author)Urban areas in coastal lowlands host a significant part of the world's population. In these areas, cities have often expanded to unfavorable locations that have to be drained or where excess rain water and groundwater need to be pumped away in order to maintain dry feet for its citizens. As a result, groundwater seepage influences surface water...article 2019

Kaandorp, V.P. (author), Doornenbal, P.J. (author), Kooi, H. (author), Broers, H.P. (author), de Louw, P.G.B. (author)Groundwater seepage influences the temperature of streams and rivers by providing a relatively cool input in summer and warm input in winter. Because of this, groundwater seepage can be a determining factor in the provision of suitable water temperatures for aquatic biota. Climate warming affects stream and groundwater temperatures, and changes...article 2019

Kaandorp, V.P. (author), de Louw, P.G.B. (author), van der Velde, Y. (author), Broers, H.P. (author)The contribution of groundwater to streams is controlled by temporally and spatially variable groundwater flow paths with distinctive travel times. The aggregated average travel time distribution (TTD) of all these flow paths functions as a catchment characteristic. Currently, research on TTDs is expanding towards dynamic TTDs and building on...article 2018

Kivits, T. (author), Broers, H.P. (author), Beeltje, H. (author), van Vliet, M.E. (author), Griffioen, J. (author)The combination of emerging antibiotic resistance and lack of discovery of new antibiotic classes poses a threat to future human welfare. Antibiotics are administered to livestock at a large scale and these may enter the environment by the spreading of manure on agricultural fields. They may leach to groundwater, especially in the Netherlands...article 2018

Yu, L. (author), Rozemeijer, J. (author), van Breukelen, B.M. (author), Ouboter, M. (author), van der Vlugt, C. (author), Broers, H.P. (author)The Amsterdam area, a highly manipulated delta area formed by polders and reclaimed lakes, struggles with high nutrient levels in its surface water system. The polders receive spatially and temporally variable amounts of water and nutrients via surface runoff, groundwater seepage, sewer leakage, and via water inlets from upstream polders....article 2018

Insight in the hydrochemical functioning of embanked polder catchments is highly relevant for improving the water quality in such areas or for reducing export loads to downstream water bodies. This paper introduces new insights in...article 2016

Massoudieh, A. (author), Visser, A. (author), Sharifi, S. (author), Broers, H.P. (author)Due to the mixing of groundwaters with different ages in aquifers, groundwater age is more appropriately represented by a distribution rather than a scalar number. To infer a groundwater age distribution from environmental tracers, a mathematical form is often assumed for the shape of the distribution and the parameters of the mathematical...article 2014

(author)Leaching of nitrate from agricultural land to groundwater and the resulting nitrate pollution are a major environmental problem worldwide. Its impact is often mitigated in aquifers hosting sufficiently reactive reductants that can promote autotrophic denitrification. In the case of pyrite acting as reductant, however, denitrification is...article 2013
