| Abstract | ||
| The objective of the study is to assess the environmental impact of using pre-treated wastewater and treated wastewater coming out of Sana’a waste water treatment plant for irrigation purposes. The analysis of pre-treated wastewater samples and samples flow out of the plant was done by measuring several biological and chemical indicators, and then evaluate the quality of this water for agricultural uses based on international criteria and standards. The pre-treated wastewater was not applicable for agricultural uses as its chemical/biological quality exceeds the international standards (BOD, COD, Faecal Coliforms, Parasite eggs, Nitrogen) which are more related to the environmental contamination and health in addition to Adj-SAR. The validity of the treated wastewater in sanaa station for agricultural irrigation can be restricted becomes of the high number of E.coli 5600 MPN /100ml although they were free of intestinal eggs and the rest of the chemical and biological in indicators wear be low recommended limit for agriculture use. | ||
