Although Mn frequently exceeds the effluent standard in South Korea, only active treatment facilities were applied to remove Mn because it was difficult to be removed by passive treatment. Because a slag reactor that removes Mn by passive treatment is being designed, design factors were proposed by relevant studies. The factors include differences in hydraulic head, the composition of substrate, variations in treatment efficiency, and the residence time. Moreover , the required pH decreases by the coprecipitation and sorption of Mn by Fe and Al hydroxides in active treatment facilities. To design efficient active treatment facilities considering the necessity of a pH readjustment tank, a relationship between the required pH and the concentrations of Fe, Al, and Mn was also proposed from relevant studies.

“…Since the release of most trace elements from sulfide mining waste are related to the oxidation of sulfides into sulfate their release can be assumed to be related to the release of sulfate [43]. By assuming a conservative behavior for sulfate through the system from release from the waste material to pore waters, groundwaters and further into the surface waters the total amounts of primary released trace elements from the waste materials can be estimated [44].…”

Alum shale was mined for oil and uranium production in Kvarntorp, Sweden, 1942–1966. Remnants such as pit lakes, exposed shale and a 100-meter-high waste deposit with a hot interior affect the surrounding environment, with elevated concentrations of, e.g., Mo, Ni and U in the recipient. Today most pit lakes are circumneutral while one of the lakes is still acidic. All pit lakes show signs of sulfide weathering with elevated sulfate concentrations. Mass transport calculations show that for elements such as uranium and molybdenum the western lake system (lake Söderhavet in particular) contributes the largest part. For sulfate, the two western lakes contribute with a quarter each, the eastern lake Norrtorpssjön about a third and a serpentine pond system receiving water from the waste deposit contributes around 17%. Except for a few elements (e.g., nickel 35%), the Serpentine system (including the waste deposit area) is not a very pronounced point source for metal release compared to the pit lakes. Estimates about future water runoff when the deposit has cooled down suggest only a slight increase in downstream water flow. There could possibly be first flush effects when previous hot areas have been reached by water.

“…Water quality in arid basins is influenced by a various of hydrochemical processes, such as water-rock interaction, land reclamation, wastewater infiltration, sewage exfiltration, and agricultural irrigation [2][3][4]. Due to the complex influences of multiple natural and anthropogenic processes in arid areas, identifying the major hydrochemical processes is difficult but highly useful [5,6].…”

Hydrochemical processes under intense human activities were explored on the basis of the hydrochemical characteristics of 109 surface water samples and 129 groundwater samples collected during August 2015 to September 2016, in the Kaidu River Basin. Results obtained in this study indicated that the water in the basin was neutral to slightly alkaline with low total dissolved solids. Rock weathering and evaporation controlled the natural hydrochemical mechanisms. Mountain groundwater and stream water were dominated by Ca2+-HCO3− type water, whereas the plains groundwater was dominated by mixed type water. The results of principal component analysis demonstrated that water-rock interaction and human activity explained 71.6% and 12.9% of surface water hydrochemical variations, respectively, and 75.1% and 14.2% of groundwater hydrochemical variations, respectively. Sulfate, chloride, and carbonate weathering were the major water-rock interaction processes. Livestock farming and agricultural activities were the primary human activities influencing the water hydrochemistry. In addition, cation exchange is another important process influencing the hydrochemical characteristics in the study area. This study would be helpful in forecasting of water quality in arid areas.
