Hydrogeoecological conditions of technogenic groundwater in waste disposal sites

Abstract

The specific hydrogeoecological conditions of aquifers of some technogenic formations, mainly iron ore skarn-magnetite and titanium-magnetite formations, are considered. The resulting wastes, which are stored in waste disposal sites during development of deposits, due to the impact of a number of factors (natural and technogenic) form technogenic waters. Waste disposal facilities are complex engineering structures (dumps and sludge storages), which in turn create their own hydrogeoecological conditions, which must be investigated in order to prevent and minimize environmental and economic damage caused by these objects to the aquatic environment. The paper presents long-term field and laboratory studies of the aquatic environment under the influence of a waste disposal facility in the Middle Urals – one of the largest tailings, representing a potential environmental and frшman-made hazard. This tailing dump contains tens of tons of waste – enrichment tailings and creates specific hydrogeoecological conditions on the territory. Based on many years of monitoring studies, an analysis of these conditions was carried out – the quality of groundwater affected by the tailings was assessed. It is shown that groundwater is of technogenic nature, i.e. are man-made waters that have a significant impact on the surface and underground hydrospheres of the territory.

Organizational, Economic and Regulatory Aspects of Groundwater Resources Extraction by Individuals (Case of the Russian Federation)

“…Establishing a maximum allowable daily production volume of 100 m 3 (which is 4000 L per hour) seems unrealistic since such a volume of water cannot be physically developed on a plot of land with an area of 10 acres, even though groundwater itself does not, as a rule, have a protective aquiclude and are subject to possible biological and chemical contamination (e.g., cesspools, various types of fertilizers, etc.) [46]. In the current situation, such a flow rate (100 m per day) can only be provided by an aquifer with sufficiently high filtration parameters (for example, medium-grained sands or weathering crust of bedrocks).…”

Developing a Comprehensive Mathematical Model for Aluminium Production in a Soderberg Electrolyser

“…The following number of aspects can be attributed to them. The development of a conceptual model of technological process should take into account a number of economic factors [47,48]; this is not considered in this paper because of the emphasis on the technical part of the issue. Moreover, this paper does not consider the environmental side of the issue [49,50].…”
