EVALUATION OF THE QUALITY OF MANANTIAL WATER SUPPLYING THE CITY OF SALVADOR (BA)

Since 2011, the Centro de Pesquisas e Desenvolvimento - CEPED performs sampling and analysis activities of the waters of the springs that supply the city of Salvador to assess the Water Quality Index (WQI). The WQI is an important indicator of the relationship between use and land cover and water quality in a watershed. The purpose of this paper is to present a study of water quality of rivers Paraguaçu, Joanes, Jacuípe, Ipitanga, which are responsible for the water supply for the population of metropolitan region of Salvador with more than three million inhabitants and highest population density Northeast North. Through this study we can conclude that there is a decrease in water quality in nearby points of urbanized areas due to lack of sanitation, as well as in areas where there is impairment of riparian vegetation cover.

Quality Indexes

Water quality indexes are a tool used to evaluate the physicochemical characteristics of a water body according to its use. The present study proposes the inclusion of oil and grease (OG) as a new water quality index (ICAMPFF-GA) parameter for the preservation of marine biota in tropical areas, since it is a typical pollutant found and measured in water bodies, causing damage to the aquatic environment. The normalized curve for OG was defined based on the percentage of surviving microorganism under a lethal concentration exposure of OG. The ICAMPFF-GA suitability was evaluated by its application to analyze marine water quality in the area of the sea outfall in the city of Cartagena, Colombia and comparing the trends of the outfall flow and the rainfall for 2017. Physical chemical data analyzed for the year 2017 shows that OG varies from 0.0 to 3.8 mg/L. The results show that the water quality index increases when rainfall and flow values increase for the rainy season. The ICAMPFF-GA can be a tool to evaluate the water quality of marine waters affected by the discharge of waters with oil and grease.

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.

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.

To clarify the relationship between changes in photochemical oxidants’ (Ox) concentrations and their precursors in Kawasaki, a series of analyses were conducted using data on Ox, their precursors, nitrogen oxides (NOx) and volatile organic compounds (VOCs), and meteorology that had been monitored throughout the city of Kawasaki for 30 years from 1990 to 2019. The trend in air temperature was upward, wind speed was downward, and solar radiation was upward, indicating an increasing trend in meteorological factors in which Ox concentrations tend to be higher. Between 1990 and 2013, the annual average Ox increased throughout Kawasaki and remained flat after that. The three-year moving average of the daily peak increased until 2015, and after that, it exhibited a slight decline. The amount of generated Ox is another important indicator. To evaluate this, a new indicator, the daytime production of photochemical oxidant (DPOx), was proposed. DPOx is defined by daytime averaged Ox concentrations less the previous day’s nighttime averaged Ox concentrations. The trend in DPOx from April to October has been decreasing since around 2006, and it was found that this indicator reflects the impact of reducing emissions of NOx and VOCs in Kawasaki.

Large sets of water quality data can leave water quality managers and decision-makers totally overwhelmed. In order to convey the interpretation of the data in a simplified and understandable manner, the water quality results from bi-monthly surveys undertaken at seven different sampling sites in the Letaba, Olifants, and Selati rivers over a two year period (February 1990 to April 1992) were reduced to index values, using a water quality index. The water quality index (Aquatic Toxicity Index or ATI) revealed spatial and temporal trends. The higher index values, recorded for the sampling sites towards the eastern part of the Kruger National Park (KNP), revealed that the water quality was better than the quality measured in the Olifants River on the western bound-ary. The lowest index values were calculated for the Selati River, with index values consistently below 50. Index values indicate that the water quality in the Selati River was unsuitable for supporting normal physiological processes in fish. The water quality of the Selati River had an immediate impact on the water quality of the Olifants River directly below the confluence. Lower index values recorded at sites further downstream was also attributed to the influence of the Selati River since there are no known point sources of contaminants within the boundaries of the KNP. The index scores also elucidated temporal trends with lower scores evident during winter months. This was due to reduced flow in the Olifants River and a greater contribution of contaminated water from the Selati River. Index values increased following the first seasonal rains due to a dilution effect. Very low index values were recorded at certain sites during flood periods due to increased turbidity, reduced oxygen, and increased metal concentrations.
