Abstract
Bahr El-Baqar drain in northeastern Egypt is considered as one of the most polluted drains in Egypt. The use of polluted water from the drain in fish farms and agricultural lands has a very dangerous environmental effect on soil and ground water. Besides, seepage from the polluted drain to the adjacent lands has a great effect on the quality of the ground water in the area. The main objective of the current research is to conduct an integrated environmental assessment for areas located at both sides of Bahr El- Baqar drain for the last 20.0 km length of the drain before it spills its water into Manzala Lake. In order to achieve that, the effects of using polluted drain water in new/old fish farms and agricultural lands were investigated. Pollution level in moor and fill lands adjacent to the drain were also investigated. In addition, effect of seepage from the polluted drain to the adjacent lands has been studied. Water and soil samples have been collected and analyzed in order to calculate the concentrations of five main heavy metals (Pb, Zn, Cd, Cu and Mn).
