Environmental assessment of surface water quality of the River Nile surrounding the project of the new Assuit barrage and ITS hydropower plant, Egypt

Owing to the great pressure experienced on the developing countries due to increasing of population and widens industrialization; developing countries have to diverse sources of energy to produce electricity, control irrigation systems and transportation means. At the beginning of 2012, the new Assiut barrage and its hydropower plant was initiated in the River Nile at Assiut city in Egypt. The chemistry of physico-chemical parameters and biological characteristics play a discriminative role for assessment of water quality in the vicinity of the hydropower plant area. About 190 water samples were collected around the project in the period of 2012- 2014, for the analysis of physicochemical properties such as pH, TDS, DO, COD, BOD, NO3 in mg/I and temperature in OC and Turbidity [NTU]. Their mean values are 8.09, 206.25, 7.15, 9.80, 5.11, 0.55 mg/l and 23.20 OC and 5.95 NTU respectively. The obtained values were compared with allowable levels stated by WHO and Egyptian laws 48/1982 for the River Nile protection from pollution. The overall water quality index is 75.50 falls in the second class [70- 90] of water quality categorization of good water quality. Biological species of water environment such as zooplankton, benthos and concentration of the heavy metals in fish were assessed in water samples and sediment around the imdustrial area. The study showed that surface water quality is suitable for industrial projects, but meeds some purification for drinking water. Recommendation to protect surface water quality from environmental pollution was suggested

Pollution from gerga sugar factory monitoring and assessment

Air quality was studied in Gerga sugar factory to assess and evaluate pollution levels that are generating from sugar manufacturing process. Pollution levels of NO, SO[2], CO, CO[z] and THG gasses and paniculate matter were detected and determined. Also, associated parameters of meteorological conditions such wind speed, wind direction, temperature and pressure were evaluated. This was done using the mobile monitoring unit. The mobile monitoring unit is a mobile laboratory with rapid response instruments for real-time measurements of gasses and particulate distribution and emission source characteristics. The results showed that air quality in Gerga sugar factory has been affected from total hydrocarbons and sulfur dioxide gases that exceeded the acceptable levels. As, for particulate matter, it is considered the worst pollution problem hi the core of the sugar factory and neighbouring colonies. In general we can say that Gerga Sugar factory affects the air quality with a limit range of pollution
