Resumo(s)
The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by
governments and of
fi
cial entities worldwide. Irrigation with wastewater may have implications at two different
levels:alterthephysicochemicalandmicrobiologicalpropertiesofthesoiland/orintroduceandcontributetothe
accumulation of chemical and biological contaminants in soil. The
fi
rst may affect soil productivity and fertility;
the second may pose serious risks to the human and environmental health. The sustainable wastewater reuse in
agriculture should prevent both typesofeffects,requiring a holisticand integratedrisk assessment. Inthis article
wecriticallyreviewpossible effects of irrigation with treatedwastewater, with special emphasison soil microbi-
ota. The maintenance of a rich and diversi
fi
ed autochthonous soil microbiota and the use of treated wastewater
with minimal levels of potential soil contaminants are proposed as
sine qua non
conditions to achieve a sustain-
able wastewater reuse for irrigation.
