“…In the northern (industrial) part of the city, the groundwater is sulphate-hydrocarbonate, hydrocarbonate-chloride and chloride-hydrocarbonate calcium, calcium-sodium, sodium-calcium, sodiummagnesium-calcium, ammonium-sodium. The type of water changes from sulphate-sodium to magnesium-chloride and calcium-chloride with salinity rising up to 6-11.5 g/dm 3 [40]. The radiation safety indicators comply with the standards, i.e.…”

“…The content of trace elements is below the maximum permissible concentration, and the main indicator of groundwater pollution in this part of the city is nitrogen compounds, as the concentration of nitrate-ion in wells of private houses reaches 1100-1530 mg/dm 3 . Some areas are noted to have excessive levels of Cr, Hg, petroleum products, phenols and other chemical elements and organic compounds [40].…”

The paper presents the results of analyzing uranium content in man-made carbonates (scale crusts) on the territory of Ufa based on examination of 42 samples. The median uranium content in the investigated samples stands at 1.44 mg/kg, which is significantly lower than the background values (scales from the Lake Baikal water, a clarke of sedimentary carbonate rocks) and data on other settlements of the Republic of Bashkortostan. Low values of uranium content are probably associated with the effects of the three leading factors, i.e. specific subsurface geology of the territory (gypsum, limestone); types of water supply; water treatment processes for the centralized type of water supply. Spatial distribution of uranium in man-made carbonates is characterized with uniformity, which is disturbed in two cases, i.e. a change of the water supply type (from centralized to individual); and material of the vessels used for boiling the water. No significant differences were detected when comparing samples of man-made carbonates associated with different sources of water supply (the bucket and infiltration types of water intake) and the types of household filters.

Оценена современная активность развития карбонатного карста как одного из опасных геологических процессов на Южном Урале и в Предуралье. Установлены геолого-гидрогеологические особенности его развития в неоген-четвертичное время.Исследованиями последних лет выявлена тесная связь поверхностных карстопроявлений и деформаций зданий и сооружений с погребенными формами палеогидросети. Освоение территорий, ранее считавшихся непригодными для строительных целей, неизбежно сопровождается серьезным воздействием человека на геологическую среду и, как результат, происходит активизация карстовых процессов. Примером природной активности развития карбонатного карста в неоген-четвертичное время является Уфимское плато, а техногеннойпромышленно-урбанизированная территория Уфимского полуострова, а также районы нефтедобывающего техногенеза.

Karst of the Southern Urals and the Cis-Urals, the Current Activity of It’s Development

et al. 2022

Recent studies have established a close relationship of surface karst manifesta-tions and deformations of buildings and structures with buried forms of paleohy-dronet. The development of territories previously considered unsuitable for construc-tion purposes is inevitably accompanied by a serious human impact on the geological environment and, as a result, karst processes are activated. The technogenic modern activity of sulfate and sulfate-carbonate karst is most pronounced within the industri-ally urbanized territories of the Belaya — Ufa (“Ufa Peninsula”) interfluve and areas of oil-producing technogenesis (Tuymazinsky, Shkapovsky, etc.). The authors created a GIS database project “Karst of the Southern Urals and the Cis-Urals”, which contains geospatial data on the manifestations of the karst pro-cess in soluble rocks in the South Urals and Cis-Urals. The database is managed using the “Karst” classifier.
