Shortfall of rain and the decreased groundwater level force farmers to use poor quality water for crop production in developing
countries. In this study, the quality of agricultural produce and soil health affected by sewage water (Patranala) irrigation
was evaluated. Sewage sediment, soil and crop samples were analyzed for physico-chemical properties. Sewage water found
to contain trace concentration of heavy metals. However, long-term application of this water for crop production could build
up a significant amount of trace metals in both soil and sediments. The DTPA extractable heavy metals ranged Cu 2.7–7.59,
Cd 0.04–0.06, Pb 1.29–2.05, Cr 0.01–0.04, Ni 0.24–1.03 and Zn 0.63–2.59 mg kg−1 soil. The heavy metal risk assessment
(hazard quotient, HQ) was calculated and found that HQ for these metals in the crops under study was in safe limits. From
the study, it is concluded that growing vegetables using sewage water of Patranala is safe, but periodic monitoring to be
carried out to avoid food chain contamination.
