“…Moretto et al (2012) adjusted the WQINSF weights based on CONAMA 357/2005, for the Pardo river basin, in South Brazil, using multivariate statistical analysis. Naveedullah et al (2016) developed a WQI to evaluate one of Siling's main reservoirs in Zhejiang Province, China. The developed index was composed of ten parameters of water quality, some of these index of water quality of the Environmental Company of the State of São Paulo (WQICETESB), and more ammonium ion.…”

Entender como e onde as atividades antrópicas influenciam a qualidade da água de um aquífero é de extrema importância para o monitoramento e manejo destas, porém as ferramentas utilizadas para esse fim são escassas. O objetivo deste estudo foi criar e espacializar um índice específico de qualidade da água subterrânea para avaliar a qualidade da água de um aquífero. Assim, através de uma padronização dos dados, bem como um dimensionamento de acordo com a sua concentração ou medição para criar os sub-índices e com base na estatística multivariada, estabeleceu-se os pesos de cada uma das variáveis envolvidas neste estudo. As variáveis utilizadas neste estudo são dados secundários fornecidos pelo IGAM, coletados no ano de 2017. Além disso, após a criação deste índice, especializou-se o mesmo para visualizar as zonas que sofrem as maiores influências antrópicas. Além disso, com base no índice espacialmente criado, foi possível identificar que a área na porção mais ao norte do mapa é onde foi encontrada a melhor qualidade da água. Assim, observou-se que o nitrato é a variável mais importante neste estudo. Portanto, foi possível concluir que o índice criado é capaz de auxiliar no monitoramento e gestão dos recursos hídricos

“…Much has been done to restore the purity of surface waters [2][3][4], unfortunately however, their state remains unsatisfactory, although some positive changes in the rationalization of water management are perceivable. Monitoring water quality and pollutant discharges are crucial for developing plans for watershed water management and protection against pollution through establishing the appropriate action plans and controlling their efficiency [5][6][7][8].…”

Nutrient Pollutants in Surface Water—Assessing Trends in Drinking Water Resource Quality for a Regional City in Central Europe

2019

This paper presents the changes in concentration of seven biogenic indices in the Wisłok River water and determines the water treatment processes required in order to obtain water fit for consumption. The investigations were conducted during 2004–2013, and water samples were collected at a measuring-control point was situated at 67.9 km on the river at the surface water intake for the water supply to the Rzeszów city dwellers. Analysis of the research results allows for the forecasting of technological and organizational changes in the treatment processes of the abstracted water. It was found that only the mean concentration of Kjeldahl nitrogen exceeded the value admissible for class I, which allowed the Wisłok River water to be classified as class II with good potential and determined the water quality category as A2, which indicates the necessity for typical performance physical and chemical treatment. Downward trends in the contents of the tested nutrients occurred during the period of investigation, except for nitrite nitrogen. Statistically significant downward trends were registered for ammonium nitrogen, Kjeldahl nitrogen, total nitrogen and phosphates. The decline in nutrient concentrations in the water of Wisłok is a tangible result of the introduction of new standards of water resource management in the catchment, compliant with the European Union legislation.

“…TSS can also cause depletion on dissolved oxygen (DO) due to the increase in surface water temperature caused by higher absorption of solar energy by such solids (Naveedullah et al, 2016). Large amounts of suspended solids (SS) can affect procreation of fish and invertebrates due to obstruction on breeding habitat (Naveedullah et al, 2016). In addition, TSS can serve as a shelter for pathogenic microorganisms and may be associated to bacterial contamination (Bakan et al, 2010;Henning et al, 2014).…”

Knowing the relationship between the total suspended solids concentration (TSS), turbidity in the waters, and that turbidity analysis can be done faster and in less expensive way, this study aimed to obtain mathematical model to estimate the total suspended solids (TSS) concentration from the turbidity values for waters of Doce river basin. For this purpose, it was used the water quality database of the Minas Gerais Institute of Water Management (IGAM). The data were pre-treated using the adjusted boxplot technique followed by adjustment of curves for the different management units and rainfall regime period. It was verified the possibility of a single curve through the dummy variable technique, subsequently. With the results it was observed that the adjusted boxplot technique proved to be useful for environmental data. Linear relationships with R² values, as a rule, were higher than 0.6, however, it was not possible to develop a single model. It is concluded that the generated models presented good adjustments being able to be used for predicting the concentration of TSS as a function of turbidity. However, each management unit in each period of rainfall regime presents particularities that were reflected in the prediction models.
