Traditionally, industrial processes produce wastes that, even though often containing useful materials, are discarded, contributing to environmental pollution and depletion of natural resources. An example such brines, flows concentrated salts, produced in water treatment processes, which now routinely discharged into receiving bodies. Brines however can also be considered as reusable materials...

The aim of the study is to assess the evolving mine water quality of closed uranium mines (abandoned between 1958 and 1992) in the Czech Republic. This paper focuses on the changes in mine water quality over time and spatial variability. In 2010, systematic monitoring of mine water quality was performed at all available locations of previous uranium exploitation. Gravity flow discharges (mine a...

Weathering of metal-sulfide minerals produces suites of variably soluble efflorescent sulfate salts at a number of localities in the eastern United States. The salts, which are present on mine wastes, tailings piles, and outcrops, include minerals that incorporate heavy metals in solid solution, primarily the highly soluble members of the melanterite, rozenite, epsomite, halotrichite, and copia...

An investigation of a childhood leukemia cluster by US Centers for Disease Control and Prevention revealed that residents of the Carson Desert, Nevada, are exposed to high levels of W and this prompted an investigation of W in aquifers used as drinking water sources. Tungsten concentrations in 100 ground water samples from all aquifers used as drinking water sources in the area ranged from 0.27...

The development of carbon capture and storage techniques has become essential to reduce mitigating CO2 emissions the atmosphere. CarbFix1 CarbFix2 projects carried out in Iceland demonstrated that waste gas from geothermal power plants can be captured mixed with effluent geofluid subsequently injected back into reservoir. This experience gained CarbFix expanded other fields around Europe, one d...

Abstract The Songwe geothermal prospect is situated in western Tanzania the Rukwa Rift of branch East African System. Thermal springs discharge along NW–SE oriented fracture zones two separate areas: main graben (Iyola, Main springs, Rambo and Kaguri) eastern (Ikumbi). Lithologies forming filling are metamorphic gneiss shist as basement rocks, overlain by Karoo sandstones, Red both silt- sandst...

Managed Aquifer Recharge (MAR) has been applied as Storage, Transfer, and Recovery (ASTR) to provide fresh drinking water for local communities at 99 locations in southwest Bangladesh since 2009. Aerobic freshwater from ponds is filtered subsequently infiltrated into anaerobic shallow brackish aquifers. At approximately 45% of these sites, relatively higher levels Fe As were observed recovered ...

Abstract Deep geological disposal is the preferred solution for long-term storage of radioactive waste in many countries. In a deep repository, cementitious materials are widely used structure and buffer/backfill repository stabilisation hazardous materials. The cement acts as physical barrier also contributes chemically to containment by buffering groundwater high pH, limiting solubility radio...
