Calculations and solutions for heavy metals pollution load from Umum and Qalaa drains to Lake Mariut, Egypt

1460-1467In Egypt, after the construction of High Dam and the controlling of the River Nile, the water flow of Umum Drain has become one of the main land-based sources regularly discharging its waters directly into the Mediterranean Sea at El-Mex Bay, west of Alexandria. On the other hand, Qalaa Drain is the polluted source, having over 70% of its water as wastewater from eastern wastewater treatment plant, (EWTP). The present work is an assessment of a seasonal study of heavy metals’ discharge from some pump stations into Umum and Qalaa Drains to control the heavy metals pollution load from each Umum and Qalaa to Lake Mariut Main Basin (LMMB). The results indicated that Lake Mariut is still suffering from the massive polluted loads from Qalaa Drain with high concentration of dissolved metals mostly in the sulphide forms. The present study highly recommends the insulation of anoxic water from Qalaa Drain
