1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. LÄS MER
2. Evaluating the Undrained Shear Strength of Sulphide-Bearing Soils in the Sundsvall Area
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Sulphide soils in Sweden are mainly found along the northeast coastline. These soils area characterized by their fine grain size, low shear strength and black, or grey, color. These soils are also found further south, in the Sundsvall area in Västernorrland, but have slightly lower sulphide content there. LÄS MER
3. Grundläggning av ny bro på postglacial lera i Uppsala
Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)Sammanfattning : I detta examensarbete har en geoteknisk utredning utförts för att bedöma ifall grundläggning aven bro över Fyrisån i Uppsala kan utföras på enklaste sätt, genom plattgrundläggning. Arbetethar grundats på att undersöka hur grundläggningen styrs av den postglaciala lerans tekniskaegenskaper. LÄS MER
4. Evaluation of cone factors for CPT-evaluation in CONRAD of sulphide- bearing soil in Mälardalen
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : The purpose of this master thesis is to investigate how to evaluate CPT-soundings in sulphide soilfrom Mälardalen in CONRAD. The objective is to conclude whether sulphide soil from Mälardalenshould be evaluated with existing methods or a new method should be developed. LÄS MER
5. Geochemical Investigation of Arsenic in Drinking Water Sources in Proximity of Gold Mining Areas within the Lake Victoria Basin, in Northern Tanzania
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : 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. LÄS MER
