Assessment of the Quality of Water of the River Una in the National Park Una on the Basis of Selected Microbiological Parameters

El estudio evaluó la calidad del agua destinada al consumo humano en el cantón Quevedo, provincia de Los Ríos, Ecuador. Se evaluaron parámetros físicos, químicos y microbiológicos del agua en nueve estaciones de bombeo del EPMAPAQ, en épocas lluviosa y seca. Se compararon los resultados obtenidos con los valores de referencia establecidos en las normativas (Acuerdo ministerial Nº 097 Norma INEN 1108, TULSMA, EPA y OMS), bajo el criterio de calidad para aguas destinadas al consumo humano y uso doméstico. Se determinó el Índice de Calidad de Agua (ICA) y la correlación estadística entre los parámetros, usando la prueba de “t” de Student, con una significancia estadística de p = 0,05 entre las dos épocas. Los parámetros: nitritos, nitratos, turbidez, sólidos disueltos totales, pH, dureza total, color y hierro, se encuentran en el rango de aceptabilidad de calidad ambiental. Los valores, manganeso y oxígeno disuelto sobrepasan los límites máximos permisibles por el TULSMA, al igual que los coliformes fecales, en época lluviosa. La mayoría de los parámetros presentaron diferencias significativas (“t” al 5%) entre las dos épocas. El agua del cantón Quevedo está levemente contaminada y requiere tratamiento de potabilización previo a su consumo. ABSTRACTThe study evaluated the quality of water intended for human consumption in the canton Quevedo, province of Los Rios, Ecuador. Physical, chemical and microbiological parameters of water in nine EPMAPAQ pumping stations were evaluated, in rainy and dry seasons. The results obtained with the reference values set out in the regulations (Ministerial Agreement No. 097 Standard INEN 1108, TULSMA, EPA and WHO) under the quality criterion for water intended for human consumption and domestic use was compared. The Water Quality Index (ICA) and the statistical correlation between parameters were determined using the test "t" of Student, with a statistical significance of p = 0.05 between the two periods. Parameters: nitrites, nitrates, turbidity, total dissolved solids, pH, total hardness, color and iron are in the range of acceptability environmental quality. Values, manganese, dissolved oxygen exceed the maximum permissible limits for the TULSMA, like fecal coliform in the rainy season. Most parameters showed significant differences ("t" 5%) between the two periods. Quevedo Canton water is slightly contaminated and requires purification treatment before consumption.

Abstract Aquatic ecosystems of urban rivers are contaminated through waste disposal, which poses a public health problem. The objective of this research was to evaluate the quality of water used for recreation and public supply of six rivers in the city of Cascavel - Paraná, including Cascavel, Quati, Bezerra, Antas, Clarito and Amambay. Samples were collected every 4 months in 2017, and their physicochemical and microbiological parameters, as well as resistance profiles of strains of Escherichia coli to antimicrobials distributed by pharmacies of the primary healthcare network, were evaluated. Parameters such as water temperature, turbidity, total nitrogen, total phosphorus, total coliforms and thermotolerant coliforms showed significant differences. The allowed limit for thermotolerant coliforms, which was set by National Environment Council, Resolution 357/2005, was exceeded in all of the six analyzed rivers. It was determined that 48.1% of E. coli strains showed resistance to nine antimicrobial tested. The highest levels of resistance were found for ampicillin (27.7%), tetracycline (27.7%) and amoxicillin (24.0%). The results of this study contribute to the understanding of the hazards associated with the contamination of springs in urban centers with wastewater containing resistant bacteria. Therefore, recovery work is necessary in these areas because of the importance of these water sources for the entire western region of Paraná state.

The quality of water is crucial for the qualification of river beaches. The Cávado River watershed (Northern Portugal) contains five river beaches with a regular and specific mandatory monitorization. The main subject of this research is the evaluation of spatial and temporal water microbiological and physicochemical parameters to assess the water quality improvement and consequently watershed management. The results of monitoring surface water, considering microbiological parameters from the five river beaches (2015/19), and physicochemical parameters from three water points along the Cávado River (2018/19) were considered. The river beaches located upstream of the town of Braga has an “excellent” and “good” quality, while the river beach located downstream shows a lower water quality. The physicochemical water results indicated that there is a progressive degradation of water quality from upstream to downstream of the river, which is associated with the influence of domestic and industrial activities. To improve water quality, continuous monitoring will be necessary, with the implementation of adequate awareness-raising programs and strategic water quality management by the population and local agents.
