“…This is attributable to decomposition of organic matter such as animal and human excreta, plant debris and dead organisms. These results are comparable to other urban rivers whose qualities are influenced by domestic, agricultural and industrial activities that release organic matter and other waste into the river [17] [19] [20] [21].…”

River Rwizi originates from the Buhweju hills. It is a major source of water for the inhabitants of Mbarara Municipality and surrounding environment. In this study, spatial variation of water quality in River Rwizi section within Mbarara Municipality was determined using cluster analysis. Laboratory analysis was conducted on water samples from five sites along the river section using standard methods for: pH, EC, TSS, TDS, turbidity, temperature, total hardness, alkalinity, salinity, colour, NH 3-N, 2 4 SO − , BOD, COD, DO, Ca, Mg, Fe, and Mn. Cluster analysis grouped the study sites into slight pollution (Spencon, GBK), moderate pollution (Katete) and high pollution (BSU, Kakoba) for dry season. For rain season, order was: slight pollution (BSU, Spencon), moderate pollution (GBK) and high pollution (Kakoba, Katete), basing on similarity of water quality variables. These results show that water pollution resulted primarily from domestic waste water, agricultural runoff and industrial effluents. Thus, water from River Rwizi is not suitable for drinking in both dry and wet seasons.

“…Thus the occurrence of higher indicator bacterial numbers in any water sample could be linked to the higher turbidity levels [33]. Suspended silt and clay, organic matter, and plankton can contribute to turbidity; hence, turbidity in a stream will fluctuate before, during and after turbulent flow [34][35].…”

Rivers are important freshwater resources for domestic and industrial activities, and the availability of good-quality freshwater is indispensable for preventing water-borne diseases and improving quality of life, especially in communities that lack a water supply system. The physicochemical parameters and coliform distribution of some selected rivers in Osun State, soutwestern Nigeria were evaluated using standard analytical procedures. The physicochemical qualities ranged as follows: pH (6.9-7.6), temperature (26-29ºC), turbidity (2.28 = 9.46 NTU), electrical conductivity (229-581 μS/cm), nitrate (0.03-0.05 mg/L), nitrite (0.00-0.01 mg/L), sulphate (3.33-20.33 mg/L), chloride ions (7.83-27.33 mg/L), dissolved oxygen (4.23-5.57 mg/L), total dissolved solids (56-184 mg/L), total hardness (78-519 mg/L) and alkalinity (50.67-146.67 mg/L). Total coliforms were detected in counts ranging from 59 to 176 CFU/100 ml of water sample. One-way ANOVA showed that pH, temperature, electrical conductivities, nitrates, nitrites, chloride, dissolved oxygen, total dissolved solid, total hardness and alkalinity were significantly different (P<0.05), whereas turbidity and sulphate were not significantly different (P>0.05) from each parameter with respect to sampling sites. Generally, results from this study suggest that the river waters are not suitable for consumption, domestic or recreational use, and confirm the importance of protecting the freshwater resources of southwestern Nigeria.

“…The researchers have always made an attempt for studying the aquatic ecosystem for extended time span whether the objective is developing the water quality index (Tripathi and Singal 2019;Tian et al 2019;Ewaid et al 2018), transitional water quality index development (Giordani et al 2009) or for long-term analysis of the physico-chemical and biological characterization of a riverine ecosystem (Jameel et al 2018;Gupta et al 2017;Le et al 2017). Pollution is such an anthropogenic nuisance that never occurs for a season or two; it is constantly being added in a river day by day due to poor sanitation activities along the banks, the industrial and agricultural discharge and direct dumping.…”

Pollution mapping in the urban segment of a tropical river: is water quality index (WQI) enough for a nutrient-polluted river?

Most of the tropical rivers of the world are being affected by multiple sources of pollution. The intensity of pollution is much bigger in the urban stretches due to discharge of untreated or partially treated sewage. A rapid and cost-effective tool is required for identification of water quality problems and their spatial variation for determining the main pollution sources and to detect relationships between various parameters. For this study, Gomti River, a major tributary of River Ganges, India, was considered which has gained substantial attention because of increasing anthropogenic pollution loads that has badly affected its water quality and ecosystem functions. The urban segment is polluted with organic substances, nutrients and heavy metals. The study provides an overview of the quality of water in the Gomti River through water quality index (WQI) and multivariate statistical techniques to check if WQI is enough for a nutrient-polluted river in the urban stretch. The study suggests that periodic monitoring and the water quality index development are not enough as it does not incorporate all the aspect of a rivers water quality. The separate assessment of nitrogenous biochemical oxygen demand, carbonaceous biochemical oxygen demand, sediment oxygen demand and the nitrification inhibition aspects are required to be integrated when developing a WQI. Present study illustrates that water quality of Gomti River has gradually worsened from upstream and downstream to middle stretch. The middle stretch was found to be most polluted as the major drains are concentrated within this stretch. Principal component analysis/factor analysis (PCA/FA) helped in obtaining and recognizing the factors/ sources accountable for river water quality differences in the study area. The findings are useful for the decisions regarding water quality management and this can also be applied for speedy and low-cost assessment of water quality of the polluted urban stretch of other tropical rivers for better environmental management and planning perspective.
