“…A few dozen kilometers east of Elbrus is the ancient Verkhnechegem caldera with an age of about 2.8 million years (Chernyshev et al 2014;Myshenkova and Koronovsky 2015). In the area of this caldera, the Chegem River flows up to the 30 th kilometer.…”

Arsenic is ranked as a significant global health hazard associated with potable water. The present study assesses the arsenic pollution of the surface waters in the mountainous regions of the central part of the North Caucasus due to the presence of geochemical anomalies and the potential health risk by its consumption for the residents. The studies were carried out from 2016 to 2022. The surface waters of 5 main rivers of the region (Kuban, Malka, Baksan, Chegem and Cherek) with their main tributaries have been studied. Samples were taken during the period of intensive melting of glaciers (summer). The determination of the soluble form of arsenic was carried out using the method of atomic absorption spectrometry. In general, arsenic concentrations in this region are lower than Clark values for river waters. Along with this, watercourses with high and very high concentrations of arsenic have been identified. Elevated concentrations of arsenic in surface waters spatially coincide with the location of geochemical anomalies. The most polluted is the Baksan River. The levels of surface waters pollution from natural and anthropogenic sources are almost the same (up to 100 µg/dm3). In this regard, an assessment of the health hazard was carried out. For residents receiving drinking water from wells located at the southern foot of Elbrus, the carcinogenic risk for adults was 4.51×10-4, which is unacceptable for the general population. The non–carcinogenic risk was 1.00 - the maximum permissible risk causing concern.

“…1). В этом районе расположена древняя Верхнечегемская кальдера возрастом около 2,8 млн лет [10,11]. По району этой кальдеры река Чегем протекает до 30-го километра (пробы 100-103, рис.…”

“…1). Для него характерно наличие кислых вулканитов, которые являются либо аэрально перенесенными продуктами активности верхнечегемской кальдеры, либо они связаны с самостоятельным центром плиоценового вулканизма в этом районе [11]. Таким образом, исследованный участок русла реки Чегем на всем своем протяжении протекает по району древнего вулканизма.…”

The content of heavy metals was determined using atomic absorption spectroscopy. Some clear regularities have been revealed for the surface waters of the Chegem river basin. The waters are characterized by a high level of natural pollution with aluminum, manganese, copper and zinc; concentrations of Pb, Mn, Cr, Zn and Al decrease downstream; higher concentrations of these metals are typical for almost all watercourses in the high-mountain zone of the Chegem river
