  1. 16. Hydraulic Modeling and Quantitative Microbial Risk Assessment of Intrusionin Water Distribution Networks Under Sustained Low-Pressure Situations

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Maryam Shakibi; [2022]
    Keywords : drinking water distribution network; EPANET; hydraulic modelling; low pressure; pathogen intrusion; Quantitative Microbial Risk Assessment QMRA ; distributionsnät för dricksvatten; EPANET; hydraulisk modellering; lågtryck; patogen inläckage; Kvantitativ mikrobiell riskbedömning QMRA ;

    Abstract : Drinking water systems aim to remove, reduce, and prevent microbial contamination in water by usingmultiple barriers from catchments to consumers. Water distribution networks are vulnerable tocontamination from external sources if they lose their physical or hydraulic integrity. READ MORE

  3. 17. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  4. 18. A Risk Assessment Framework to Evaluate the Effect of Climate Change on Drinking Water Quality

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Shivam Gusain; [2022]
    Keywords : Climate change; quantitative microbial risk assessment; systematic review; drinking water;

    Abstract : The impact of climate change on drinking water is one of the fastest-growing challenges within the water sector. Microbial contamination of drinking water has been a serious issue for decades now and will exacerbate in the coming future. READ MORE

  5. 19. Temporal Dynamics In Microplastics Within An Indoor Environment: Insights From A Novel Tape-Lifting Method

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Matilda Wiklund; [2022]
    Keywords : Microplastics; tape-lifting; atmospheric fallout; urban environments; Mikroplast;

    Abstract : Microplastics (MPs) constitute a risk to both human and environmental health. It is vital to identify sources and pathways to take the necessary action and limit the number of MPs in our environments. However, we currently have a limited understanding regarding MPs' variation with time in urban environments in an indoor setting. READ MORE

  6. 20. Är rengjorda klippskär för rakapparater kontaminerade?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Sofie Kieri; [2022]
    Keywords : klippskär; vårdrelaterade infektioner; nosokomiala infektioner; veterinärmedicin;

    Abstract : Vårdrelaterade infektioner är ett känt problem inom veterinärmedicinen. Veterinärkliniker har uppgetts utgöra en risk för spridning av patogener och antibiotikaresistenta bakterier. Vårdrelaterade infektioner orsakas ofta av opportunistiska bakterier som normalt inte orsakar infektion. READ MORE
