“…In recent years, the problems of pollution in water bodies have become a point of local concern. The water quality released from the High Dam in Aswan shows little degradation and it remains remarkably clean from chemical pollution until it reaches to the Delta [21]. Water quality of the River Nile in Aswan is generally meeting the water quality standards stipulated by the Egyptian governmental law 48/1982 [22].…”

This study demonstrates the impact of wastewater of El-Sail Drain on the health of Oreochromis niloticus collected from two sites of River Nile at Aswan Governorate. One of these sites is before (I) and the other is after (II) the disposal point of El-Sail drain. The physicochemical parameters of water (pH, electric conductivity, total dissolved solids, dissolved oxygen, biological and chemical oxygen demands, nitrite, nitrate and ammonia) were determined. Heavy metals (Cu, Pb, Cd and Ni) concentrations in water and fish tissues (gills, muscles, liver and gonads) were detected. The microbiological, parasitological and pathological conditions of fish were also investigated. Higher values of pH, EC, BOD and COD were detected in site II than from site I. In contrast to DO, nitrite, nitrate and ammonia which were lower in site II. Heavy metals concentrations in water of both sites, especially Ni, Pb and Cd exceeded the permissible limits and its abundance followed the order: Pb>Ni>Cd>Cu. Total bacterial count, total coliform, Salmonella sp., Shigella sp. and E. coli were detected in higher numbers in water samples from site II. Moreover, the fish caught from that site revealed higher bacterial and parasitic infection. The bioaccumulation of Ni and Pb exceeded the maximum permissible limit; however, Cu and Cd concentrations were below the permissible limit in different tissues. The bioaccumulation factor of Cu showed its highest value in liver. The histopathological lesions were more prominent in fish collected from site II. So, consuming fish caught from the studied sites around El-sail drain disposal point represents serious hazard on human health.

“…However, to obtain safe drinking water, it is necessary to get a pathogen free drinking water (Manafi, 2011).As such, the Nile has a dominant influence on the country's economic, cultural, public health, social and political aspects (Mahrous, 1997 ;Rabeh, 2007). The Nile provides approximately 98% of Egypt's water supply (Saad and Goma, 1994). The Nile provides 96% of Egypt's water (Barnes, 2012).…”

Water quality assessment of drinking water has been studied in Zagazig city, El-Sharkia Governorate, Egypt between Summer 2015 to Autumn 2016. Water samples were collected from 7 sites during the four seasons. These sites are raw water (Bahr Mowees), Prechlorinated Water and Postchlorinated Water from Zagazig drinking water treatment plant and 4 drinking water sites which are (Zuhur District, Zagazig university Area, El-Janine street Area, Farouk Street Area). The obtained results clearly indicated that the physical and chemical results agreed with the WHO limit and standard limits for drinking water in Egypt, in Zagazig except alkalinity and residual chlorine. This study indicated the Total viable bacterial counts (T.V.B) on nutrient agar medium, total coliform (T.C.F) and feacal coliform (F.C.F) on endo agar base medium at different sites in Zagazig city through four seasons expressed as colony forming unit (CFU)/100 ml sample of each group using membrane filter technique. In this study the bacterial isolates were isolated from all sites during different seasons in Zagazig city and purified. It is reported that untreated water sources were more heavily contaminated with both total and faecal coliforms than treated water sources.

“…The River Nile is recognized as the longest river, and can be considered as one of the most important rivers in the world. At Delta Barrage, North of Cairo at the River Nile bifurcates into two branches namely Damietta and Rossetta and four Rayahs (irrigated channels) namely El-Nassery, El-Behery, El-Monofiy and El-Tawfiky (Saad and Goma, 1994;Abdel Aziz, 2005;Ghannam et al, 2015;Talab et al, 2015 andAbd El-Karim et al, 2016). These Rayahs are vital for irrigation, navigation, fishing and other domestic uses in many Governorates of Egypt (Hossam and Ahmed, 2005).…”

Taxonomy and seasonal diversity of Nile molluscs are important to understand the ecological impact of these animals on sustainability of River Nile ecosystem dynamics. The present work aims to explore and evaluate the taxonomy and diversity of four benthic molluscan species; two gastropods and two bivalves, in three of Egyptian irrigated Nile channels (Rayahs). The specimens were collected seasonally during the period from spring 2014 to winter 2015.Taxonomy of specimens were studied from the views of morphology and 18S rRNA gene analysis. The Gastropod species-1 and-2 had 5-6 light or dark brown whorls, but the last whorl of Gastropod sp.-2 was larger than that in Gastropod sp.-1. The phylogenetic analyses of 18S rRNA gene showed that both of Gastropod species formed monophyletic cluster, which had paraphyletic lineage with species Viviparus georgianus, implicating two new species under the genus Viviparus. The shell of the Bivalve sp.-1was ovoid with light greenish brownish or yellowish color, while the Bivalve sp.-2 had light brown to grayish elongated shell. Both of Bivalve spp.-1and-2 showed 18S rRNA gene sequence identity; averages of 89% and 92%, respectively, with Lampsilis cardium suggesting new genera within the family Unionidae. Gastropod sp.-1 showed highest abundance, during winter in El-Rayah El-Tawfiky, while the lowest was recorded during spring in El-Rayah El-Behery. Gastropod sp.-2 was abundant during summer in El-Rayah El-Behery. The seasonal distribution of the two studied bivalves declared the highest abundance in both of El-Rayah El-Behery and El-Rayah El-Tawfiky during winter, while declined during spring in all Rayahs.
