Wastewaters from Tenth Ramadan and El-Obour cities and El-Khadrwia drain verify their environmental effects. The study focused to study Wastewater Quality Index (WQI) and their suitability during 2018-2019. The data showed almost of chemical parameters were unacceptable for water irrigation suitability that used to derive criteria and guidelines of hazards ions interactions, FAO for irrigation and Canadian Water Quality Guidelines for aquatic organism. The results indicate that there is no effect of metals in the case of wastewater use for agricultural purposes, whereas for aquatic life, all measured metals except Fe+3, Mn+2, Pb+2, Zn+2 and Cu+2 show different degrees of contamination in wastewaters of investigated areas.

The obtained results indicated organic pollution values of examined variables were higher than the recommended standards and they were major waste impacts. They supported by Organic Pollution Index (OPI) evaluation that ranged from 15 to 822 while the maximum Comprehensive Pollution Index (CPI) and OPI values were (16.1 and 822) for cheese whey wastewater at El-Obour City affects aquatic environmental live in this area and producing healthy harms. The study concluded primary treatment removed 50-60% of pollution. So, study recommended use nanoparticles with low cost to acquire positive ecological impacts and increase national goals.
