Abstract
The current research is designed to assess the impact of wastewater use on the soils, water resources and public health comparing with chemical, biological and physical analysis with local and international standards. One sample was collected from outlet of wastewater treatment system, ten ground water samples and eight soil samples were collected at 0-60m depth for physical and chemical laboratory analysis. The wastewater is relatively saline (1.7 dS/m), contain BOD and COD, 89.4 and 106 mg/l, respectively. The EC is relatively low (1711 μS/cm), TDS amounts is moderate (1112 mg/l) and the total coli form is very high (up to 78×106 CFU/100 ml). The groundwater and surface water analytical results showed that NO3 concentration and F. coli are higher than the WHO recommended and the soils are highly saline (>15 dS/m). In conclusion, the wastewater is considered unsuitable for irrigation use due to it’s a high risk on the surrounding environmental resources.
