Ecological well-being of water sources as a factor of an industrial city sustainable development

Abstract

In this article a “well-being” degree of the water supply source of a major industrial center (Chelyabinsk, Russia) is determined in compliance with criteria of the sustainable development goal 6 “Clean water and sanitation” (SDG 6). It is demonstrated that the Shershnevskoye reservoir corresponds to the main water quality indicators recommended by the SDG 6 and is the “good-quality” water body according to the national standards for maximum permissible concentrations for drinking water use during the entire period of the reservoir existence. The dynamics of pH level, mineralization, dissolved oxygen, nitrogen, phosphorus and heavy metals content in the water of the reservoir for the period from 1975 to 2020 was analyzed. Stable neutral-alkaline conditions in the reservoir water were revealed; a statistically significant decrease of mineralization, increase of dissolved oxygen content and a strong trend of mineral phosphorus growth are observed, which characterizes strengthening of photosynthetic processes and increase of productivity and anthropogenic eutrophication level of the water body. The risk factor for the reservoir ecological well-being is heavy metal content, especially iron, manganese and copper.

Ecological and chemical assessment of the status of water bodies in the Vologda region

“…Russa has many similar research programs in various regions. These are studies of the water sources quality on the basis of physical and chemical properties [2][3][4][5][6][7][8][9][10][11][12], as well as microbiological contamination of water [13][14][15][16][17]. The studies used different methods like physical, chemical and biological analysis carried out using currently accepted approved methods.…”

Complex Characteristics of the State of the Shershnevsky Reservoir (Russia, Chelyabinsk)

“…В Европе и США наиболее распространенным методом оценки различных поверхностных вод является water quality indices (WQIs), расчет которого основан на использовании таких показателей, как температура, рН, мутность, взвешенные вещества,  SCIENTIFIC REVIEW № 1, 2023   BIOLOGICAL SCIENCES  концентрация фосфатов, нитратов, растворенного кислорода, БПК5, фекальных колиформ, и его различные модификации [4]. Согласно цели устойчивого развития по питьевой воде и санитарии, общее качество воды оценивается на основе базового набора из пяти параметров по поверхностным водоемам: содержание в воде растворенного кислорода, электропроводность (минерализация), содержание азота, содержание фосфора и рН, которые определяют доброкачественность водного объекта [5]. Для характеристики процессов эвтрофирования и антропогенного загрязнения широко применяется индекс трофического статуса (trophic status indices TSIs) и индекс тяжелых металлов (heavy metal indices HMIs) [6].…”
