Assessment of heavy metal accumulation (Cu, Fe, Zn, Pb, and Ni) was conducted in the wastewater irrigated soil in Allahabad district of Uttar Pradesh, India, using contamination factor (CF) and pollution load index (PLI). Samples from each sampling points taken at depth 0-<5, 5-<10, 10-<20, 20-<25cm and were analyzed using Atomic Absorption Spectroscopy (AAS). The maximum contamination of iron was observed in soil irrigated with wastewater of drain. The study area was observed to be contaminated with metals and contamination factor calculated of Cu (maximum0.0796), Fe (maximum 5.2119), Zn (maximum 0.0285), Pb (maximum 0.1163) and Ni (maximum 0.0007) in all different season during 2011-13.The pollution load indices (PLI) were found to be maximum is 0.0045 in winter season and minimum is 0.0034 in monsoon season with increase in depth (0-25 cm) indicating that the study area was polluted by all the observed heavy metals. These results support both the managed utilization of wastewater for irrigating field and regulate the discharge of wastewater into the water from households and runoff that are located upstream.
