ABSTRACT
The aim of this study was to evaluate the potential cultivation of lettuce (Lactuca sativa) with domestic wastewater effluents with different levels of treatment from a compact WWTP in Brazil. Vegetables were grown in five treatments: nutrient solution (control), secondary effluent diluted 50%, secondary effluent not diluted, tertiary effluent UV irradiated, and UASB effluent. Microbiological analyses from leaves showed low levels of contamination with E. coli, thermotolerant coliforms and total coliforms. Salmonella spp. and helminth eggs were not detected. However, roots showed hardly any concentration of these microorganisms. These results shows that it is possible to cultivate leafy vegetables in a hydroponic system with treated effluents, taking care at the moment of harvesting vegetables.
