Treated wastewater generated at Hussein Medical Center was used in irrigation of sweet corn, tomato and water melon in an attempt to study the effect of this water on soil composition, soil characteristics, and crop yield. Of particular interest also was the distribution of bacteria among the environmental components involved, which were soil, water and plant material. The results showed that the treated wastewater did not drastically affect soil composition and soil content of nutrients and trace elements when compared with those of soil irrigation with fresh water. However, the bacterial counts of the soil and crop material were higher when treated wastewater was used in irrigation as compared with fresh water. Also, bacterial contamination was higher when furrow irrigation was employed as compared with drip irrigation. Consequently, treated wastewater used in irrigation to increase crop yield, save fresh water and decrease the use of chemical fertilizers must be strictly monitored for its bacteriological quality in order to avoid high levels of bacterial contamination of soil and crop
