“…On the other hand, turbidity describes the reduction in water clarity caused by suspended particles. In the ALM reservoir, a turbidity value of 7.46 NTU was found, which is very similar to that reported by Loucif et al [ 17 ], but higher turbidity values have been reported in other water bodies [ 12 ]. According to Inatius and Rasmussen [ 50 ], a high turbidity value can reflect an increase in algal biomass and organic matter.…”

“…The deterioration of water quality in reservoirs is a major concern issue since water availability depends on water quantity and quality. Consequently, water quality should be monitored [ 17 , 18 , 19 ]. Maintaining the water quality of water resources requires continuous monitoring of the physicochemical and bacteriological characteristics of the water [ 20 , 21 , 22 ].…”

Agricultural activities are highly related to the reduction of the availability of water resources due to the consumption of freshwater for crop irrigation, the use of fertilizers and pesticides. In this study, the water quality of the Adolfo López Mateos (ALM) reservoir was evaluated. This is one of the most important reservoirs in Mexico since the water stored is used mainly for crop irrigation in the most productive agricultural region. A comprehensive evaluation of water quality was carried out by analyzing the behavior of 23 parameters at four sampling points in the period of 2012-2019. The analysis of the spatial behavior of the water quality parameters was studied by spatial distribution graphs using the Inverse Distance Weighting interpolation. Pearson correlation was performed to better describe the behavior of all water quality parameters. This analysis revealed that many of these parameters were significantly correlated. The Principal Components Analysis (PCA) was carried out and showed the importance of water quality parameters. Ten principal components were obtained, which explained almost 90% of the total variation of the data. Additionally, the comprehensive pollution index showed a slight water quality variation in the ALM reservoir. This study also demonstrated that the main source of contamination in this reservoir occurs near sampling point one. Finally, the results obtained indicated that a contamination risk in the waterbody and further severe ecosystem degradations may occur if appropriate management is not taken.

“…Thus, water from Lake Bunyonyi is less likely to cause health concerns and thus Lake Bunyonyi still meets the minimal standards to serve as a source for drinking water. The observed NO 2 -N values were lower than 32.9 ± 0.7 μg/L and 0.82 ± 0.25 mg/L recorded at Lake Bunyonyi, and Lake Tonga by Tibihika et al [42] and Loucif et al [22], respectively. On the other hand, the recorded NO 2 -N values were higher than 1.3 ± 0.7 μg/L obtained at Lake Oubeira reported by Keyombe and Waithaka [18].…”

The current study was carried out to examine the spatial and temporal variations of physicochemical water quality parameters of Lake Bunyonyi. The observations were made on the surface water of Lake Bunyonyi for 1 year to determine the water quality. The basic 12 variables used to determine the quality of water were measured monthly at nine stations. Water temperature, dissolved oxygen (DO), turbidity, electric conductivity (EC), pH and Secchi depth (SD) were measured in the field, while parameters like total nitrogen (TN), total phosphorus (TP), nitrite-nitrogen (NO2-N), nitrate-nitrogen (NO3-N), soluble reactive phosphorus (SRP) were determined following APHA 2017 standard guidelines for physicochemical analysis. Taking into account standard guidelines for drinking water by the Uganda National Bureau of Standards (UNBS) and the World Health Organization (WHO), the water quality index (WQI) was used to determine the water quality. Temperature, DO, pH, turbidity and EC did not differ significantly among the study stations (p > 0.05) but showed significant temporal variations among the study months (p < 0.05). Likewise, TN, TP, NO2-N, NO3-N and SRP did not differ significantly among the study stations (p > 0.05) but showed significant temporal variations among the study months (p < 0.05). The WQI values ranged from 28.36 to 49 across and from 28.2 to 56.2 between study months with an overall mean value of 36.9. The measured water quality variables did not exceed the UNBS and WHO standards for drinking water in all months and at all stations. According to these values, the water quality of Lake Bunyonyi generally belongs to the ‘good’ class in terms of drinking water quality based on the WQI classification. The study findings are fundamentally important for policy makers in setting guidelines for effective lake management.

“…The negative conditions from both continental and atmospheric environments can instantly reflected by these ecosystems (Çolakoğlu & Çakır, 2004;Bernot & Dodds, 2005). Although the studies on composition and abundance of microorganisms in biosphere have a lot of significance, in recent years it was also the investigations of bacteria in aquatic ecosystems have got an increasing significance (Jamieson et al, 2003;Hunt & Sarıhan, 2004;Agbogu et al, 2006;Niemi & Raateland, 2007;Sabae & Rabeh, 2007;Mishra & Batt, 2008;Suneela et al, 2008;Mishra et al, 2009Mishra et al, , 2010Saha et al, 2009;Bulut et al, 2010;Kumar et al, 2010;Venkatesharaju et al, 2010;Nguyen et al, 2016;Islam et al, 2017;Alves et al, 2018;Loucif et al, 2020). A lot of study is also carried out in our country.…”

It is inevitable that the running waters which are used for a lot of different activities like fishing, irrigation, domestic water usage are under threat because of the settlements, industrial or agricultural activities. To provide the sustainable usage of these ecosystems we have to know their current features and their balance under changing environmental conditions. In the present study, the ecological status of Tunca (Tundzha) River which is located on Turkish Thrace was evaluated based on environmental conditions and bacterial features of the river. For this aim, the research has been carried out at 5 different stations in the river between October 2010 and September 2011 at monthly intervals. Some environmental conditions (temperature, dissolved oxygen, pH, conductivity, salinity, chloride, turbidity, hydrogen sulfide, magnesium, calcium, total hardness, NO3-N, NO 2 -N, sulfate, orthophosphate, suspended solid substances, biological oxygen demand) and bacterial features (total coliform, fecal coliform, and Escherichia coli bacterial abundances) were examined performing at the same time samplings. Consequently, it was determined that the water quality of Tunca River has proper physicochemical conditions allowing surviving of living things, but bacteriological findings belonging to the river was not found proper for direct use of water by human. Also, the correlations were evaluated between the obtained environmental features and the bacteria by using Spearman's index. While positive correlations were found between TMAB density and some environmental parameters (water-air temperature, EC, magnesium, nitrate nitrogen, sulfate, o-phosphate, and suspended solids); negative correlations were found between TMAB density and the other parameters (pH, hydrogen sulfide, calcium, total hardness, and BOD 5 ).
