Abstract
The response of olive orchard with same age and type to irrigation with
treated municipal wastewater and freshwater was investigated in three years.
Physical and chemical properties of the treated municipal wastewater reuse in
agriculture (the effluent) produced by the Sheikh Ejleen wastewater treatment
plant in Gaza Strip, freshwater, soil, and olive oil were determined and compared
with Palestinian and international standards. The biological oxygen
demand (BOD) of Sheikh Ejleen effluent is 60 mg∙l−1, which indicates low quality
effluent. The results indicate that most of olive oil quality parameters—
including heavy metals and trace elements for both fruits irrigated with
treated wastewater or irrigated with freshwater—fall within the acceptable
standard limit values. Moreover, soil analysis shows that organic content and
cation exchange capacity were improved in soil irrigated with treated wastewater
in comparison with that irrigated with freshwater. The results also show
that there is no trace elements or heavy metals accumulation in soil.
