    bioaugmentation - drinking water - Organic micropollutants biodegradation - rapid sand filtration

    A cost-effective approach for efficient organic micropollutants (OMPs) removal is to optimize existing infrastructure at drinking water treatment plants. A promising option is rapid sand filtration (RSF), as OMPs removal has been observed in this treatment technology. However, the mechanisms and pathways involved are not fully understood and strategies to optimize removal have yet to be thoroughly explored. Therefore, this article firstly described basic RSF functions that can support OMPs removal. OMPs can be removed by chemical and biological Mn/Fe oxides or degraded co-metabolically by ammonia oxidizing bacteria and methane oxidizing bacteria. In addition, heterotrophic bacteria can metabolically transform OMPs and their transformation products. Then, we reviewed current literatures described OMPs removal in RSF, showing biodegradation can contribute significantly to OMPs removal. Thereafter, we presented strategies to improve OMPs biodegradation, including bioaugmentation, optimizing hydraulic conditions by adjusting contact time and backwashing intensity, and adding biocarriers to retain biomass during rapid flow rates. Finally, we provided recommendations for further research towards optimizing and maintaining OMPs removal in RSF for safe drinking water production. This review therefore gives a critical evaluation of RSF-based technologies for OMPs removal from drinking water and provides recommendations for further improving OMPs removal in RSF.

    conversion factor - drinking water - exposure assessment - food additives - Nitrate - nitrite

    Dietary exposure to nitrate and nitrite occurs via three main sources; occurrence in (vegetable) foods, food additives in certain processed foods and contaminants in drinking water. While nitrate can be converted to nitrite in the human body, their risk assessment is usually based on single substance exposure in different regulatory frameworks. Here, we assessed the long-term combined exposure to nitrate and nitrite from food and drinking water. Dutch monitoring data (2012–2018) and EFSA data from 2017 were used for concentration data. These were combined with data from the Dutch food consumption survey (2012–2016) to assess exposure. A conversion factor (median 0.023; range 0.008–0.07) was used to express the nitrate exposure in nitrite equivalents which was added to the nitrite exposure. The uncertainty around the conversion factor was taken into account by using conversion factors randomly sampled from the abovementioned range. The combined dietary exposure was calculated for the Dutch population (1–79 years) with different exposure scenarios to address regional differences in nitrate and nitrite concentrations in drinking water. All scenarios resulted in a combined exposure above the acceptable daily intake for nitrite ion (70 µg/kg bw), with the mean exposure varying between 95–114 µg nitrite/kg bw/day in the different scenarios. Of all ages, the combined exposure was highest in children aged 1 year with an average of 250 µg nitrite/kg bw/day. Vegetables contributed most to the combined exposure in food in all scenarios, varying from 34%–41%. Food additive use contributed 8%–9% to the exposure and drinking water contributed 3%–19%. Our study is the first to perform a combined dietary exposure assessment of nitrate and nitrite while accounting for the uncertain conversion factor. Such a combined exposure assessment overarching different regulatory frameworks and using different scenarios for drinking water is a better instrument for protecting human health than single substance exposure.

    Amoebae - Chlamydiales - drinking water - environment - one health - Waddlia chondrophila

    Waddlia chondrophila is an emerging pathogen belonging to the order of Chlamydiales. This obligate intracellular bacterium was initially isolated from an aborted bovine fetus and is associated with adverse pregnancy outcomes in women. The ability of W. chondrophila to reside and replicate within a range of free-living amoebae implies a possible widespread environmental presence. Potential hosts of W. chondrophila are present in Dutch drinking water. This study therefore investigated the presence of W. chondrophila DNA in drinking water by analysing 59 samples from ten drinking water systems throughout the Netherlands. Samples were taken at three distances from the treatment plant, during both summer and winter. Twelve of the samples were positive, originating from two of the treatment plants, of which three samples were quantifiable.

    animal welfare - animal production - poultry - broilers - animal nutrition - drinking water - animal health
    This report describes the methods of water provision in the current housing and management of broilers and broiler breeders and the possible impact of these management practices on animal welfare (including animal health). It provides an overview of drinking behavior of chickens, the physiology of water intake and factors affecting water consumption in broilers and broiler breeders. Based on scientific literature and expert opinion it is estimated that the current methods of water provision to broiler chickens do not have an effect on welfare. The current methods of water provision to broiler breeders are estimated to affect broiler breeder welfare, but evidence from scientific literature is lacking. It is described which management methods can be applied to reduce the welfare impact of water provision to broilers and broiler breeders. Finally, recommendations for further research are provided

    Local projects conducted within the framework of the Natural Capital Netherlands (NKN) programmeidentified various opportunities for mutual improvement of natural capital and the economy. In a follow-upstudy we investigated whether the insights gained also apply to other parts of the Netherlands. Which areasoffer the best opportunities? What measures are needed in these areas to actually capitalise on theseopportunities, and who are the relevant stakeholders? To address these questions, the local opportunitiesidentified in the NKN projects were explored at the national level, using ‘opportunity maps’. The three localprojects are: Greening the Common Agricultural Policy, Clean Water and Delta Programme

    Natuurbeheerders zitten soms in hun maag met percelen die vanwege hun landbouwkundig verleden een hoge fosfaatlast kennen, omdat dit de ontwikkeling van waardevolle natuur belemmert. Afgraven is duur, uitmijnen tijdrovend, maar wat dan? Kan hergebruik van ijzerrijk drinkwaterslib uitkomst bieden? De eerste resultaten van veldproeven met dit restproduct van drinkwaterwinning zijn hoopgevend.

    Ze hebben veel gezamenlijke belangen, maar in de praktijk verloopt de samenwerking tussen agrariërs en de watersector niet altijd soepel. Boeren zien waterschappen als bolwerken van bureaucratie en waterschappen vinden boeren maar een stelletje zeuren. Twee werelden… and never the twain shall meet? Nee, zo erg is het niet, want soms gaat het ook wél goed.

    Door de vergrijzing zal de emissie van geneesmiddelen en röntgencontrastmiddelen naar het oppervlaktewater toenemen. De effecten van toenemende emissies op de waterkwaliteit worden versterkt bij lage rivierafvoeren, die naar verwachting steeds vaker en langduriger zullen optreden in een veranderend klimaat. In deze studie zijn prognoses gemaakt van de toekomstige concentraties van een aantal relevante organische microverontreinigingen in de Rijn en Maas in het jaar 2050. De voorspelde concentraties van diverse geneesmiddelen en röntgencontrastmiddelen in de Rijn en de Maas overschrijden de ERM-streefwaarden voor oppervlaktewater als bron van drinkwater. Sporen van enkele organische microverontreinigingen kunnen doordringen in het drinkwater.

    arsenic mitigation - Bangladesh - deep tube well technology - drinking water - Multi-level Perspective on transitions
    This paper explains why and how deep tube well as a safe drinking water technology has become dominant in mitigating the arsenic crisis in rural Bangladesh. We do so by applying insights from the Multi-Level Perspective on transitions in explaining changes in the safe socio-technical drinking water regime in rural Bangladesh. Data about seven dimensions of regime change were gathered from key actors through in-depth interviews, focus groups sessions, a survey, and a workshop. The findings reveal that with the introduction of deep tube well as an arsenic mitigation technology, the observed changes in the seven dimensions help to transform the existing safe drinking water regime in order to re-stabilise it. Technological attributes, symbolic meaning, industry structures, and techno-scientific knowledge have supported an evolving dominance of the deep tube well. Besides, user practices as well as related infrastructures have adapted to the use of deep tube wells, and new policies stimulated its application. We argue that the dimensions of the technology change in the existing regime are consistent with the features of incremental innovation. By offering such insights, we show the relevance of the Multi-Level Perspective on transitions to analyse socio-technical innovation in a developing world context.

    Lokaal uitgevoerde praktijkprojecten in het kader van het programma Natuurlijk Kapitaal Nederland laten zien dat er kansen zijn voor de wederzijdse versterking van natuur en economie. Dit leidt tot de volgende vragen: welke kansen zijn er om de opgedane kennis binnen deze praktijkprojecten op te schalen naar andere gebieden in Nederland? Waar liggen deze kansrijke gebieden. Wat zijn mogelijke maatregelen en relevante stakeholders om deze kansen daadwerkelijk in winst om te zetten? Om antwoorde te krijgen op deze vragen zijn de praktijkprojecten met behulp van 'kansenkaarten' in landelijk perspectief geplaatst.

    Drinkwaterbedrijven zijn belangrijke partners bij het realiseren van natuurbeleid. De sector beheert zo’n 23.000 ha en is daarmee de 4e natuurbeheerder van Nederland. In een natuurlijke omgeving zijn drinkwaterbronnen beter beschermd tegen verontreinigingen en is minder zuiveringsinspanning nodig om drinkwater te maken. In de Rijksnatuurvisie (2014) wordt met regelmaat verwezen naar de rol van drinkwaterbedrijven als natuurbeheerders. Om samen te zoeken naar invulling van deze natuurvisie, is in een Groene Tafel ‘drinkwater en natuur’ (april 2014) afgesproken de samenwerking tussen overheden, drinkwaterbedrijven en maatschappelijke organisaties te versterken. In 2004 is een studie verricht naar de betekenis van de drinkwatersector voor de natuur. Dit rapport is een update van deze studie. Het geeft een overzicht van het belang van de drinkwatersector voor de natuur in Nederland en wat er sinds 2004 is veranderd op dat gebied.

    Membrane filtration of ground, surface, or sea water by reverse osmosis results in permeate, which is almost free from minerals. Minerals may be added afterwards, not only to comply with (legal) standards and to enhance chemical stability, but also to improve the taste of drinking water made from permeate. Both the nature and the concentrations of added minerals affect the taste of the water and in turn its acceptance by consumers. The aim of this study was to examine differences in taste between various remineralised drinking waters. Samples selected varied in mineral composition, i.e. tap water, permeate, and permeate with added minerals (40 or 120 mg Ca/L, added as CaCO3, and 4 or 24 mg Mg/L added as MgCl2), as well as commercially available bottled drinking waters, to span a relevant product space in which the remineralised samples could be compared. All samples were analysed with respect to their physical–chemical properties. Sensory profiling was done by descriptive analysis using a trained panel. Significant attributes included taste intensity, the tastes bitter, sweet, salt, metal, fresh and dry mouthfeel, bitter and metal aftertaste, and rough afterfeel. Total dissolved solids (TDS) was a major determinant of the taste perception of water. In general, lowering mineral content in drinking water in the range examined (from <5 to 440 mg/L) shifted the sensory perception of water from fresh towards bitter, dry, and rough sensations. In addition, perceived freshness of the waters correlated positively with calcium concentration. The greatest fresh taste was found for water with a TDS between 190 and 350 mg/L. Remineralisation of water after reverse osmosis can improve drinking quality significantly.

    discolouration - drinking water - loose deposits build-up - pilot studies

    Tap water discolouration occurs due to resuspension of loose deposits (LD) that accumulate in drinking water distribution systems. Strategies for discolouration control involve network pipe cleaning and replacement of cast-iron pipes. However, the sole application of such measures is not generally effective. Therefore, a deeper understanding on processes associated with LD origin and development is required. Transparent (but covered) test rig pipes (Ø = 23 mm) continuously supplied with drinking water at steady flow through mode (7–9 months) were used to investigate LD build-up under laminar flow (0.2–4.1 cm/s) conditions. Rather than continuously and homogeneously, LD developed as spots, and predominantly at the pipes' bottom. Results suggested that particle attachment may be added to settling as a LD build-up process. This is consistent with LD cohesive–adhesive properties, as shown by LD repose angle tests, as well as to the occurrence of flocculent extracellular polymeric substances-EPS in LD.
