  3. 12. A geophysical survey in the Chocaya Basin in the central Valley of Cochabamba, Bolivia, using ERT and TEM

    University essay from Lunds universitet/Geologiska institutionen

    Author : Hannes Pilser; [2020]
    Keywords : ERT; TEM; geophysics; Cochabamba; aquifer; Earth and Environmental Sciences;

    Abstract : The Chocaya Basin is situated in the north-western part of the Valley of Cochabamba, Bolivia, where a semi-arid climate prevails. The increasing population is dependent on local aquifers for drinking water and irrigation. Wells are used to extract water. READ MORE

  4. 13. Mapping of contaminant dispersion from a polluted mining area by geochemical and geophysical methods, Rävlidmyran,northern Sweden : Use of geochemical and geophysical studies to investigate contaminants

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Astrid Theander; [2019]
    Keywords : ;

    Abstract : After open pit mining, the pit can either be backfilled or be filled with groundwater andbecome a pit lake. These lakes tend to be acidic and contains high concentrations ofmetals, which increases the environmental risks in the area. One of these pit lakes isRävlidmyran in the Skellefte ore district.
