    Abstract : There are about 700,000 on-site sewage facilities (OSSFs) in Sweden, almost a quarter of which amount only to septic tanks for sludge collection and removal, with no form of post-treatment. All these OSSFs contribute about 10 % of the total anthropogenic phosphorus (P) load from Swedish coasts to the Baltic Sea. READ MORE

  2. 2. Groundwater occurrence and quality in Bulawayo province, Zimbabwe

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Anton Nygren; Edvard Nordenskjöld; Erik Östblom; [2016]
    Keywords : total dissolved solids; salinity; electrical conductivity; electrical resistivity tomography; vertical electrical sounding; magnetic field; auger holes; saturated hydraulic conductivity;

    Abstract : This study focused on determining the groundwater flow paths in the crystalline subsurface rocks of the Bulawayo metropolitan, Zimbabwe, through analysing the discontinuities of the electrical properties of the ground, as well as in the magnetic field of the underlying rocks. Further, borehole water quality was analysed by measuring and mapping several chemical parameters, specifically TDS, salinity and the electrical conductivity. READ MORE
