“…Alkaline water causes iron deficiency by increasing the pH of soil to unacceptable level. Drinking water quality determinants are broadly classified into physical (such as taste, odor and color), microbial (viruses, protozoa, helminths, total coliform (TC) bacteria, Escherichia coli (ECo)) and chemical (BOD, COD, F -, NO 3 -, Fe, Cu, Ca, PO 4 2-, Cr, and others) (Sorlini et al, 2013;WHO, 2011;Amenu, 2014).…”

Awash river has been impaired by various types of pollution owing to waste released from different socio-economic activities in its basin. This research was aimed at evaluating its quality status with respect to drinking and irrigation water uses. Based on accessibility and land use severity, 17 sample sites were chosen along the river and sampling was done twice in each of the dry and wet seasons. Thereafter, both onsite and offsite water quality analyses were undertaken following standard procedures. Canadian Council of Ministers of Environment Water Quality Index (CCME WQI) was applied to compute the water quality indices. Accordingly, the drinking and irrigation water quality indices of the upper basin were found to be 34.79 and 46.39 respectively, which were in the poor and marginal categories of the Canadian water quality ranking. Meanwhile, the respective indices for the middle/lower basin, which were 32.25 and 62.78, lie in the poor and fair ranges of the ranking. Although the difference in the dataset used for the two cases and natural purification in the course of the river might contribute to the difference in WQI, it is generally conceivable that the water quality of the river is below the good rank. Establishment of wastewater treatment plants and storm water quality management at hotspot areas are recommended to improve the quality.

Bodrum peninsula is one of the major tourism centers of Turkey due to its abundant seas, its natural beauty, its history, and cultural heritage. Water needs of the Bodrum peninsula are generally obtained from the groundwater wells of Çamköy, Karaova, and center of Bodrum, as well as from Mumcular and Geyik dams. In this study, quality of the raw blended water sources that provide drinking water to the Bodrum peninsula were investigated using 31 parameters. These parameters were analyzed as per the standards of World Health Organization, EU (Europe Union), Water Pollution Control Regulation and the Regulations for Human Consumption of Water. According to the results of raw blended water analysis, turbidity, ammonia nitrogen, organic matter, manganese, total coliform, biological, and chemical oxygen requirements parameters are found above the standard values. For this reason, the planned treatment plant has features that can ensure that these parameters are improved. The processes that need to be built into the treatment plant to reach the desired drinking water quality standards should be composed of aeration, coagulation, flocculation, precipitation, filtration, and disinfection units. Study also explains that the disinfection at the treatment plant must be conducted with chlorine and ozone, while the filtration process must use dry and granular activated carbon filters. In the study, the flow schema of the proposed treatment plant for the peninsula is also given. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1274–1284, 2018

“…One such ecosystem in Africa is the Lake Chad Basin, with the Logone River and the Chari River. Research studies describing the water quality of the Logone River have been published [2,3]. Along this line of this study, we focused our attention on heavy metal pollution in the Chari River at N’Djamena.…”

This study was carried out to identify and assess the water quality of the Chari River. The Chari, 1200 km long, is Chad’s major water source. Municipal sewage, industrial wastewater discharge, and seasonal run-off from agriculture are regularly fed into the river. Several trace metals such as Cu, Zn, Fe, Ni, Cr, Mn, and Cd, were measured in different sampling stations located along the Chari River at N’Djamena in different campaigns from 2008 to 2010. Overall, manganese, zinc, chromium, and copper concentration levels were mainly in the range of the permissible limits prescribed by WHO guidelines (WHO 2011). Nickel, iron, and cadmium concentrations were still high. This preliminary study allowed us to identify the magnitude of toxic pollutants, which are responsible for Chari River water contamination in the study area. This study revealed that urgent measures must be taken to protect the local people from health problems resulting from high concentrations of heavy metals.
