Major ion chemistry, weathering process and water quality of natural waters in the Bosten Lake catchment in an extreme arid region, NW China

The paper is devoted to the development of proposals concerning the improvement of surface water bodies and the appointment of target indicators of the natural waters’ quality. The paper considers a variety of problems of preserving, restoring and improving the quality of natural surface waters: from regional features of the formation of natural water composition, to differences in the requirements for the quality of water consumed. The object of the study is the qualitative indicators of the waters of natural water bodies, and the subject of the study is the methodological approaches to the normalization of these indicators. The purpose of the work is to identify the main shortcomings in the domestic system of rationing the quality of natural waters, and to form appropriate proposals. For this purpose, the following tasks were set and solved: to review the methodological approaches to assessing and rationing the quality of natural waters used in some foreign countries and in the Russian Federation, to identify the main causes and shortcomings; to make proposals for improving the current system of water quality rationing. The result of this work is the conclusions about the lack of impact of the strategy operating in Russia in the development of schemes of complex use and protection of water objects, standards of permissible impact on water bodies, the appointment of permissible discharge limits in terms of maintaining and improving the water quality of natural water bodies. The reasons that led to this are indicated. The necessity of taking into account, in addition to the physical and chemical composition, also hydrobiological parameters is shown. It is concluded that instead of fisheries management standards, environmental standards should serve as the basis for target indicators of water quality of natural water bodies, which determine the well-being of humans and the stable functioning of aquatic ecosystems, taking into account regional factors. Proposals were made to adjust the methodological approaches to the implementation of this strategy. According to the authors, these proposals will speed up the solution of the main objectives of the strategy – the ecological improvement of water bodies, the preservation of unique aquatic ecosystems and the environmentally safe development of territories that previously experienced relatively small anthropogenic impacts (Eastern Siberia and the Far East)

Abstract Shigaze city is situated in the southwestern Tibetan Plateau and is the second largest city in the Tibet Autonomous Region. Groundwater is the major source of domestic and drinking water for urban inhabitants. In this study, the major ion chemistry and a water quality assessment of groundwater were studied using geochemical methods and fuzzy comprehensive assessment. Groundwater was classified as slightly alkaline soft and hard freshwater, and the influence of anthropogenic activities on groundwater was relatively weak. The dominant cations and anions were Ca2+ and Mg2+ and HCO3− and SO42−, respectively. Overall, the mean concentrations of major ions in groundwater increase gradually over time, except for NO3−; however, the mean value of pH decreases over time. Most groundwater samples belong to the type of HCO3-Ca, and the groundwater has a trend of evolution from HCO3-Ca to the mixed type. Rock weathering was the main hydrogeochemical process controlling groundwater hydrochemistry, and the dissolution of carbonate and silicate minerals were the primary contributors to the formation of the major ion chemistry of groundwater. Major ions of groundwater in the urban area of Shigaze are below the standard limits, and the groundwater is excellent for drinking according to the fuzzy comprehensive assessment.

Groundwater is prime and major source of drinking water in our world. Groundwater in Jharkhand is also used for drinking, domestic, irrigation, mining and industrial etc. purposes. In Jharkhand some population are suffering from scarcity of pure drinking water and some population have partial facility with drinking water as groundwater of many area of Jharkhand are contaminated with fluoride, arsenic, heavy metals and iron etc. dangerous chemicals. This review paper focuses on current status of groundwater and contamination of different water quality parameters based on major ion chemistry in Jharkhand. The discussed water quality parameters in this study are water temperature, pH, electrical conductivity, total dissolved solid, total hardness, calcium, magnesium, iron, sodium, potassium, chloride, fluoride, arsenic, carbonate, bicarbonate, phosphate, nitrate and sulphate.

The water quality of the Meenachil river at Kottayam has been studied with reference to toxic trace metals during pre and post monsoon seasons for 10 stations during May 2009-September 2009. The metals analyzed include Zinc, Manganese, Iron, Lead, Copper and Cadmium. Among the metals studied, iron, lead and cadmium showed higher concentrations above the permissible limit for drinking water prescribed by Bureau of Indian Standards. Iron and lead showed higher concentration during post monsoon and the cadmium content was high during pre-monsoon. It was observed that the main causes of deterioration in water quality might be due to the discharge of domestic wastes, municipal wastes, terrestrial runoff from seepage sites, agricultural sites and also due to geological weathering process.

The work is devoted to the actual problem of environmental safety and quality assessment of various water sources Mohyliv-Podilsky district of Vinnitsa region. It has been carried out hydrochemical analysis and calculated an index of pollution of natural waters, biological testing performed using a battery of test organisms, given recommendations to improve the water quality of the study area.It has been established that the most indicative parameters of pollution of water supply sources are hardness indicators, concentration of cadmium, lead, nitrates. None of the investigated sources have corresponded to the “clean water” indicator. Water samples that as a result of hydro-chemical analysis had been characterized by relatively safe, exhibited chronic toxicity for invertebrates. It has been found that water from a centralized source is characterized by the acute toxicity and leads to changes in living organisms at the cellular level. It is recommended to carry out quarterly water sampling in the indicated sources; minimization of the use of nitrogen fertilizers in settlements, in particular, near water supply sources.

Purpose: to assess the quality of water in water bodies of the Volga-Akhtuba floodplain from an ecological viewpoint, taking into account the modern regulatory framework in the field of environmental protection. Materials and Methods. To assess the quality of natural waters from an ecological viewpoint, a complex indicator calculated by basic analyte markers that characterize typical negative impacts was used. The following hydrochemical indicators were taken as analyte markers: pH, mineralization (dry residue), suspended solids of natural origin, total iron, total manganese, ammonium (N), nitrites (N), nitrates (N), phosphates (PO4), chemical oxygen demand (COD). Results. The ecological state of water bodies was determined by hydro-chemical indicators of surface waters and bottom sediments using the example of such representative objects as water bodies on the territory of the Volga-Akhtuba floodplain: lakes Peschanoe, Varyuzhka, Zhestkovo, erik Chayka, lakes Beshenoe, Chubatoe, Yamy, erik Shumrovatyy, lake Shirokogorloe. In accordance with the provisions of GOST R 58556-2019 “Assessment of water quality in water bodies from an ecological point of view”, the quality of water from an ecological viewpoint, the degree of quality disturbance and changes in the state of aquatic ecosystems under anthropogenic load have been determined. Conclusions. Petroleum products have been recorded in the water bodies of the Volga-Akhtuba floodplain (lake Varyuzhka, erik Shumrovatyy). The analysis of hydrochemical indicators of water quality and bottom sediments shows that currently the overall level of pollution of the considered water bodies does not reach critical levels of permissible values.
