Abstract The impact of extracting lignite in Lupoaia open pit over waters is local and regional, and temporary. The hydrographic network in Lupoaia open pit depends on River Motru, with its afluents, Ploștina and Lupoița Valley Rivers. The aquifers are to be found in the coal layers V-XII, mainly of sands formation. The impact over water in Lupoaia consists of water pollution and of changes in both the quality and the quantity of ground and surface waters. The surface waters are polluted resulting in industrial wastewaters, household wastewaters and waste rainwater. The wastewater is polluted within maximum admitted limits. The quality of groundwaters is influenced and modified by extracting coal resulting in the extinction of some aquifers. Environmental risks that can occur when extracting lignite are water floods, landslides, disasters which can be prevented by building guard channels around the open pit. The actions for reducing the impact are, in general, accomplished through monitoring both the water pollutants and the morphological changes caused by extracting lignite. That is why wastewater treatment plants must function. The impact of the activity in Lupoaia open pit over the hydrographic net of the area is to be observed during the entire extracting period, and monitoring this activity is highly demanded by the European environmental protection laws.

The Impact

The quality of surface water remains an important issue today. This is particularly acute for water bodies located in the urban-basin geosystems. Purpose. To estimate pressure of atmospheric precipitation within the urban landscape basin geosystem on the river water (by example of the Kharkiv river). Methods. Field landscaping, ecological, landscape-geochemical; analytical; system analysis; chemical analytical; statistical Results. An assessment of the state of surface waters under the impact from the surface runoff of atmospheric origin during 2014-2016, and partly from 2017-2019, formed under the influence of the transport (partly residential) subsystem of the urban area and surface waters in Kharkiv. On the salt content, the characteristic of water quality is "moderately polluted" (1,6); on the tropho-saprobiological indicators, the quality of water is characterized as "polluted" (from 3.1 to 2.75 along the river). It is in this context the impact of waters, which is formed in the conditions of the urban environment for the quality of natural waters, is well demonstrated. The presence of high values of pollutants and natural factors. The assessment of the quality of water on the content of specific indicators is "moderately polluted" (from 2.28 to 1.85). Conclusions. The water of the Kharkiv region, which has a strong influence from the urban environment, has a grade III quality; the water is "moderately polluted". Environmental assessment indicates the impact of surface runoff already on the middle part of the river, which increases in accordance with the conditions of the operation of urban landscapes and anthropogenic (transport) load.

Climate change is a serious, widespread threat and requires an urgent global response, including in the management of environmental risks. The authors of the study, the results of which are presented in this article, first of all, set the task of assessing the ESG risks of Russian companies at the regional level. The methodology of the study was based only on the analysis of environmental risks due to the historical features of the development of the Russian Federation, the approach of S&P Global in the field of corporate sustainability assessment was adopted, and then the initial values of the companies ‘ E-ratings were adjusted using the impact map developed by the United Nations. To test the proposed approach to assessing environmental risks, we used a sample of data on types of economic activity in the context of the subjects of the Russian Federation. As a result of applying the proposed approach to data sampling, companies were assigned to one of the three categories that determine their exposure to E-risk: high, moderate, and low environmental risk. The E-risk exposure was also assessed based on the company’s regional affiliation to the relevant federal district. The main conclusion of the study was the confirmation of the need to improve the quality of analytics of companies ‘ exposure to environmental risks, the need for more detailed information disclosed by companies.

Economic Considerations

The purpose of this work is to check construction and operation costs for simplified post-treatment trains able to produce water displaying a quality suitable for different agricultural uses. Having in mind the quality of most of surface waters in Italy, the main parameters to control for a general purpose reclaimed water supply are microbial quality and TSS content. Therefore a contact filtration followed by disinfection is to be considered the minimum option, while the use of polishing ponds can be strictly limited in many Italian regions due to the area requirements and to the need to provide a full lining of bottom and levees. Some data referring to surface waters quality and to the Italian epidemiological situation are given. On the basis of the current Italian situation, the construction and operation cost increases due to a polishing section, downstream a standard municipal WWTP, are evaluated and the impact of different technical choices is shortly discussed (disinfection options, chemicals, etc.). Some considerations about the link existing in Italy between the cost of water for irrigation and the agricultural economy are made.

The Impact

Despite major investments into the remediation of wastewater, and the reduction of fertilizers, the quality of small river surface water in agricultural and rural regions of Czechia is still very low. The Mastník stream flows through an agricultural area before combining with the Vltava river; a portion of the Mastník stream water inevitably terminates in the Slapy Reservoir. The quality of the water has been analyzed using data from indicator concentrations from both the Vltava River Basin Authority study profiles, and the author’s monitoring profile. The data show that the steps that have been taken – primarily the construction of wastewater treatment plants – have led to a gradual improvement in the surface water quality by some parameters. Presently, a growing concentration of chlorophyll–α and a lack of dissolved oxygen are influencing the final quality of the water. In the case of the Mastník stream, it is particularly necessary to improve the remediation of wastewater from small households, and to reduce the impact of water erosion on agricultural soil.

The Impact

In order to investigate the impact of the 1988 fires on the chemistry and water quality of shallow ground water in Yellowstone National Park, a two­year program of sampling and analysis was begun in August, 1989. Samples from ground-water wells for which pre-fire chemical data could be obtained were selected for this study. Although it may have been anticipated that the surface waters would show some effects of fire, in terms of increased sedimentation and the addition of ash-laden runoff, the effects of the fires on ground water are less predictable. The purpose of this investigation is to determine the character and extent of these effects.

The Impact

The mining industry is known for the intense environmental impacts it triggers, especially when it is developed in an open environment. Pit lakes are formed in depleted deposits and may be promising opportunities for use by society as well as troubling environmental liabilities. While these artificial basins are increasing numerically in many parts of the world, they are still little known researchers in the Environmental Sciences, which makes their environmental management challenging. The main objective of this study was to evaluate the environmental quality of sediments from three deactivated open-pit gold mines, located in the Mara Rosa, Brazil, through chemical, ecotoxicological and genotoxicology analyses. For this purpose, we collected samples in the dry season boom, and subsequently, we analysed metals. In sequence, acute ecotoxicological and a genotoxicology test (comet assay) were developed with Danio rerio fishes, in concentrations of 3.12%; 6.25%; 12.5%; 25%; 50% and 100%, in addition to the control group. The results indicated that the three lakes are environmentally compromised, especially Lago Azul, whose waters and sediments are undergoing an intense process of geological conditioning. Our results did not verify the ecotoxicity of the sediments of any of the lakes, only behavioural alterations in the test organisms exposed to the concentrations of 25%, 50% and 100% of the samples obtained in the Lago Azul. About the sediments, DNA damage at Danio rerio was detected in the three investigated environments, although fishes kept in the water sampled at Lago Azul presented the most extension of DNA damages.

The Impact

Treated municipal wastewater produced in Kuwait is used mainly in agricultural and landscape irrigations. However, there are strong doubts that severe sludge bulking and foaming problems, particularly during winter seasons, may render this water unsuitable for irrigation purposes. To assess the impact of these problems on the quality of irrigation water in Kuwait, samples of secondary and tertiary effluents and sludge-mixed liquor were collected weekly from two wastewater treatment plants for nine months. Routine wastewater quality parameters were then determined for the collected influent and effluent samples. Further, dominant filamentous bacteria in the sludge-mixed liquor samples collected from the aeration tanks were also identified and quantified using a molecular method called Vermicon Identification Technology (VIT). Obtained results of the effluents’ qualities were then statistically analyzed and compared to Kuwait’s irrigation water standards. Statistical results indicated that secondary effluents were greatly impacted by sludge bulking and foaming problems, while tertiary effluents were slightly affected. This finding highlights the importance of having tertiary treatment units in plants to encounter sludge bulking and foaming problems.

Case Basis

A number of possible relationships between climate change and water quality of Dutch surface waters have been investigated and an indicative quantification of the impact of climate change on water quality has been established. The analysis focused on water quality during periods of low flow and extreme heat, which are assumed to increase in frequency and intensity due to climate change. The results indicate that the impact of climate change on water quality cannot be generalised and should be assessed on a case by case basis. However, the impact on extreme situations (floods and droughts) seems to be largest, whilst water quality under average discharge conditions appears to be relatively unchanged.

Abstract. This work is part of a program to study and monitor the impact of human activities in the cities of Missour and Outat El Haj on the quality of the surface waters of the average Moulouya (Morocco).The aim of this study is to evaluate in time and space, the degree of metallic pollution of surface water of the average Moulouya during the period (September 2014, January, April and July 2015). The results of this study suggest that the waters of the ten stations in the study area are relatively contaminated with heavy metals. The contents of the analyzed metals are high and variable in the wastewater of the cities of Missour and Outat El Haj and in the waters of the Moulouya average.The anthropogenic impact on the ecosystems selected for this work is highlighted by: the high metallic contamination of the water of the stations located downstream of wastewater discharges of the cities of Missour and Outat El Haj, and the variation of the contents according to an increasing concentration gradient from station M1 to M9.
