Water, soil and crops management, animal and human exposure affect so much the risk associated with water reuse that no quality standards are universally accepted. The study aimed to evaluate the impact of using bioremediated wastewater or soil on maize plant. Use of bioremediated and polluted sewage water and soil had significantly difference on length, fresh and dry weight of maize plant compared to normal soil and tap water. The mean values of shoot fresh and dry weight were 30.62 and 4.62 g/plant, respectively in polluted soil, and 29.23 and 4.19 g/plant in bioremediated soil, then 27.88 and 3.58 g/plant in normal soil. Polluted wastewater recorded the highest fresh and dry weight, followed by bioremediated wastewater, then tap water. Nitrogen, phosphorus and potassium (N, P and K) of maize plant were significantly differed according to type of soil and water used. The highest values of Cd and Ni in shoot maize were 0.581 and 9.070 ppm in polluted soil, followed by bioremediated soil (0.257 and 4.393 ppm), then normal soil (0.096 and 3.717 ppm). The corresponding values with polluted water were 0.434 and 7.493 ppm, respectively, followed by bioremediated water (0.266 and 5.27 ppm), then tap water (0.234 and 4.417 ppm).
