Bacteriological Monitoring for the Northern Khors of Lake Nasser, Egypt

Sayeda M. Ali, Amal A. Othman and Mohammed T. Abbas
Lake Nasser and its khors are important source of fresh water and freshwater fish in Egypt, therefore, the water management and quality control should be carefully considered to avoid any defectiveness at an appropriate time. Thus, this study was planned to evaluate microbial loads for water (surface and bottom water layers), sediments and plants in Northern khors of Lake Nasser (El-Ramla, Kalabsha, Wadi Abyad and Rahma) during two seasons, winter and spring, 2015. The physicochemical and bacteriological analyses indicated that, Among khors, El-Ramla khor (the nearest one to the high dam, Aswan city and then increased the activity of fishing) recorded the highest total dissolved solids as well as total and faecal coliform bacteria (means of 174.3 mg L–1, 312 and 45 MPN/100 mL, respectively). Winter season recorded higher microbial loads. In addition, bacteriological analyses for sediment and plant samples showed that, total diazotrophs were found in high numbers reaching >1.9×109 CFU g–1 sediment and 7.7×107 CFU g–1 plant compared to total bacteria which reached >3.2×109 CFU g–1 sediment and 4.4×107 CFU g–1 plant. In general, the results indicated that, microbial loads in water, sediments and plants affected by human activities (fishing and tourism) and environmental conditions. Also, the water quality of the Northern khors of Lake Nasser is acceptable in respect to physico-chemical parameters but not bacteriological parameters and it is acceptable for irrigation water not for drinking water.
