Effects of land use on chemical water quality of three small streams in Budapest

AbstractThe location and development of cities has been influenced basically by various environmental factors. However, the relationship is bilateral, because not only the environment can affect the city, but the city can affect the environment in different ways, depending on recovery. This is especially true in the case of large cities such as Budapest where the different geological, geomorphological, hydrological, soil and bio-geographical conditions can be changed in very small areas, which implies that land use can be also modified as well. The aim of our study was to determine the chemical water quality of three small streams in Budapest which have same water flow and compare the field and the laboratory test results. Between many natural characteristics of these streams similarity is evident, however, several differences were found between the watersheds in terms of human land use. Statistical data analysis was performed as well, which was the aim to explore the relationship between the parameters. Overall, according to our study it can be concluded, the small streams have similar water chemical properties, but some parameters need special attention in the future, because the investigated small streams can be categorized into polluted and sometimes heavily polluted category.

Changes in the land use and land cover in areas adjacent to water reservoirs directly affect the quality of this water. This research presents a study on the water quality in the basin of one of the most important public water supply reservoirs in the city of Juiz de Fora, Minas Gerais. The main objective of this study was to analyze the behavior of limnological parameters and the correlation with land use and land cover in the contribution basin of the Doutor João Penido reservoir (CBJPR). The methodology was based on the analysis of water quality parameters, related to water samples collected from 2012 to 2015. Six sampling points were chosen from different locations: spring, medium course, main tributaries of the reservoir and the reservoir catchment. The parameters analyzed were turbidity, total solids (TS), oxygen consumed (OC), dissolved oxygen (DO), electrical conductivity, total nitrogen (TN), total phosphorus (TP), E. Coli, temperature, pH and total dissolved solids (TDS). The Kendall’s tau test was used to analyze the correlations between the parameters of water quality, land use and land cover in the CBJPR. In general, measured parameters showed better results in spring and in reservoir catchment, showing a worse quality of the water along the tributaries and the dilution power of the reservoir. The correlations pointed to the need for protection and preservation of forests in strategic locations to ensure good water quality.

The Relationship

Many catchments in northern Algeria, including the coastal Mitidja Basin in the north central part of the country have been negatively affected by the deterioration of water quality in recent years. This study aims to discover the relationship between land use change and its impact on water quality in the coastal Mitidja river basin. Based on the data of land use and water quality in 2000, 2010 and 2017, the relationship between land use change and surface water quality index in the Mitidja Watershed was discussed through GIS and statistical analysis. The results show that the physical and chemical properties of the Mitidja river basin have obvious spatial heterogeneity. The water quality of upstream was better than that of downstream. There was a significant spatial relationship between the eight water quality indicators and three land use types, including urban residential land, agricultural land and vegetation. In most cases, settlements and agricultural land are the dominant factors leading to river pollution, and higher vegetation coverage helps to improve water quality. The regression model revealed that percentage of urban settlement area was a predictor for NH4-N, BOD5, COD, SS, PO4-P, DO and pH, while vegetation was a predictor for NO3-N. The analysis also showed that during this period, urban settlement areas increased sharply, which has a significant impact on water quality variables. Agricultural land only had a significant positive correlation with PO4-P. The results provide an effective way to evaluate river water quality, control water pollution and land use management by landscape pattern.

Chemical Water

Water is an important factor in fulfilling the needs of living things, therefore the water that is used must be free from bacterias and do not contain any toxic substances. The most common water source comes from the river. Ciliwung River as one of the main rivers used for drinking, household needs, industrial needs, and transportation must have good water quality. Therefore, the Ciliwung River water quality needed to be known. The water quality is measured based on the parameters such as the physical water quality and the chemical water quality. The measurement of those parameters are classified to be complicated as it measured by laboratorium research, so that the identification of the chemical water quality parameter could be done through the physical water quality that is easier and simpler to be measured. This study aims to determine the variable of the physical water parameters that can be used to identify the chemical water quality parameters, so that the water quality of the Ciliwung River can be known in a simpler way. Statistical method that can be used to see the relationship between the two variable groups is the canonical correlation analysis. Canonical correlation analysis is a method in multiple variable analysis used to investigate the relationship of two groups of variables using the linear combination principle of the two variables. Based on the results of the canonical correlation analysis, it can be concluded that there is a relationship between the physical quality of water and the chemical quality of water. The correlation exists between the variables of physical quality of water, which are the water temperature and the content of suspended substances in water, with the variables of chemical quality of water, namely groups of metals (manganese levels in water and iron content in water) and groups of acid (the level of deep phosphate in water, the level of sulfate in water, the level of nitrite in water, and the level of nitrate in water). The relationship between the physical quality of water is positive between the temperature of water and the chemical quality of water whereas negative between the levels of suspended substances in water and the chemical quality of water.

Water quality is an important tool to support the planning and management of water resources. This article has as its main objective to evaluate changes in the quality of the surface waters of the Timbó stream as a function of flow in an experimental watershed located in São Cristóvão (SE), northeastern Brazil. Four sampling campaigns were carried out in 2018 to evaluate pH, dissolved oxygen, electrical conductivity, total dissolved solids, turbidity and temperature at three collection points. Data on land use and occupation and the flow of the Timbó stream were also obtained. The land use and occupation survey indicated that 51% of the total area of the microbasin is occupied by forests and that 49% is composed of pasture, undergrowth and exposed soil. The correlation analysis identified a strong correlation (p-value <0.05) between the studied parameters, with an emphasis on a direct relationship between Q and TUR (r = 0.9) and Q and O (r = 0.6) and an inversely proportional relationship between TDS and CE (r = -0.8), confirming the results of a principal component analysis, where the parameters contributing the most to the quality of the investigated water resource were CE, TDS, OD and turbidity.

Community Infrastructure

The social infrastructure and needs of the various communities coexisting in a city are associated in considerably substantial and strong relationship with its surrounding environment. There are numerous parameters which influence the social infrastructure and community needs with respect to its integration with the land use of that city. Accessibility of proper terminals for public transportation, institutes, and hospitals parks etc. These parameters are studied along with parallel analysis of the total area covered and existing population of the city. Social infrastructures in a city have a large impact on the quality of life of the people in the urban centers. SAS Nagar (Mohali) is a counter magnet city of Chandigarh and one of the the most well-known planned city in Punjab, India. Mohali started developing as a counter magnet in the early 1990’s. It was initially known as Mohali village, a part of the Union Territory of Chandigarh. Mohali inhere with phases/ sectors including the new industrial areas, commercial centers and the educational institutions like as C-DAC Mohali in the vicinity of the residential areas. Mohali is spread over a total area of 167.67 sq. km out of which 32.58 sq.km is under the MC area with is characterized by very well planned areas. Despite of being a well-planned city of Punjab, India; Mohali still have a shortage of appropriate opportunity of services with low openness to the needs of the people. This study focuses on the relationship between land use and the social infrastructure with emphasis on the relationship analysis with geospatial planning techniques. The quality of life of people depends on the accessibility to quality of social and community infrastructure; it also impacts the migration pattern and the movement of daily commuters for their various reasons in the city. The advancement of the city is being anticipated as per the increase of the urbanization along with accessibility to proper social infrastructure, which satisfies the essential & functioning demand of the city. The development of the city is of two types’ i.e. compact development and sprawl development (depends on the density of population per sq.km). The assessment study of community infrastructure and social needs of Mohali includes various types of operational functioning parameters for study like; directional analysis, population wise analysis and area wise analysis. These social and community infrastructural needs have their own norms and standards for the city level services and as well as neighbourhood level assistance, which categorize their accessibility for the integrated land use pattern and population for services. By using open source GIS, the served areas and un-served areas along with their names are bring classified properly as per the given parameters.

Anthropic activities as well as land use and occupation are closely linked to water and soil quality. An alternative to assess their influence on water quality in water bodies is through biomonitoring using Allium cepa as a bioindicator organism. This technique allows the detection of cytogenetic abnormalities in Allium cepa root meristematic cells after contact with analyzed water samples. Thus, we evaluated the genotoxic potential of water samples from the Rio das Antas (Antas River) along the urban perimeter of the city of Irati, Paraná, Brazil. With the aid of GeoEye Satellite high-resolution fused orbital images, we searched for possible relationships between the use and occupation of land around this river. Biomonitoring was performed at three different sampling points. Statistical equality between the negative control and Point 1 and between Points 2 and 3 was obtained using Fisher's test and a Principal Coordinate Analysis (PCoA). The former presented a low frequency of abnormalities chromosomes and the latter presented larger averages. In addition, Point 1 had strong influence of tree vegetation. Points 2 and 3, demonstrated a strong influence of urbanized area, with significant degradation of permanent preservation areas (áreas de preservação permanente – (APP). The results showed remarkable anthropogenic interference to the ecosystem. Furthermore, this indicates importance of an APP watercourses functioning to preserve the quality of the water resources.

При изучении качества воды источника водоснабжения г. Самары Саратовского водохранилища особое внимание было уделено основным показателям, влияющим на выбор реагентной обработки: мутность, перманганатная окисляемость и цветность. Сезонные изменения качества воды водохранилища требуют постоянной корректировки дозы реагентов с целью достижения нормативных требований к качеству очищенной воды. Приводятся результаты производственных исследований изменения качества воды Саратовского водохранилища в створе водозаборов г. Самары за 20172019 годы по мутности, перманганатной окисляемости и цветности. В связи с аномальными температурными перепадами и наступлением осеннего паводка (конец декабря 2019 г. и январь 2020 г.) резко изменилось качество воды водохранилища по цветности и перманганатной окисляемости. Отмечено, что увеличение указанных показателей потребовало повышения дозы реагентов при очистке исходной воды. Оптимальная доза реагентов постоянно коректируется в зависимости от состава исходной воды на флокуляторе Lovibond ЕТ-750 . Регулярное проведение пробного коагулирования позволило поддерживать качество очищенной воды в соответствии с нормативными требованиями СанПиН 2.1.4.1074-01 Питьевая вода. Контроль качества , кроме цветности и железа общего, так как превышение этих показателей наблюдалось в пределах погрешности методов измерения.While studying the water quality of the water source of the city of Samara the Saratov water reservoir, special attention was paid to the main indicators that influence the choice of chemical treatment: turbidity, permanganate index and color. Seasonal changes in the water quality of the water reservoir require constant adjustment of the chemical dose in order to meet the regulatory requirements to the quality of treated water. The results of the studies of changes in the water quality of the Saratov reservoir at the water abstraction points of the city of Samara for 20172019 by turbidity, permanganate index and color are presented. Due to the abnormal temperature differences and onset of autumn flood (end of December 2019 and January 2020), the water quality in the water reservoir dramatically changed in color and permanganate index. It was noted that an increase in these indicators required an increase in the dose of chemicals during the source water purification. The optimal dose of chemicals is selected with Lovibond ET-750 flocculator depending on the composition of the source water. Regular test coagulation allowed maintaining the quality of purified water in accordance with the regulatory requirements of SanPiN 2.1.4.1074-01 Drinking water. Quality control , except for color and total iron since the values of these indicators were increased within the measurement accuracy.
