1. 1. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Henriette Nishimwe; [2023]
   Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

   Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

3. 2. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Klara Skoog; [2022]
   Keywords : Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

   Abstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

4. 3. Geochemical Investigation of Arsenic in Drinking Water Sources in Proximity of Gold Mining Areas within the Lake Victoria Basin, in Northern Tanzania

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Enrico Lucca; [2017]
   Keywords : ;

   Abstract : Access to safe drinking water is a challenge for rural communities in many developing countries. Drinking contaminated water endangers human health and impairs social and economic development. Arsenic (As) is a metalloid widely distributed into the environment and is highly toxic in its trivalent inorganic form. READ MORE

5. 4. Modelling reactive transport of acid mine drainage in groundwater : Effect of geochemical processes spatially variable flow source location and distribution

   University essay from KTH/Industriell ekologi

   Author : Tegenne Tekelu Geberetsadike; [2004]
   Keywords : Acid Mine Drainage AMD ; reactive transport; geochemical processes; flow variability; pH buffering; metal attenuation; groundwater; modelling; LaSAR-PHREEQC;

   Abstract : Impacts from mining waste deposits on groundwater resources have been recognized invarious parts of the world; though varied in scale depending on the composition of mineralsbeing mined, the level of technology employed and environmental commitment of thedevelopers. Mining activities usually involve milling, concentrating, and processing of oreswhich will result in a huge amount of waste, called tailings, usually deposited inimpoundments as a slurry, composed of fine grained geological material (uneconomicalminerals), chemicals utilized in the processs, and water.
