Lettuces irrigated with shallow groundwater were more contaminated (8% at both Pikine and Patte d’Oie sites) compared to those irrigated with wastewater (4% at Pikine) or well water (5% at Patte d’Oie). Results confirm that the reuse of wastewater in irrigation is an alternative to animal manure. Its risk of microbial contamination can be significantly reduced by washing the vegetables with tap water before they are sold.Text1 digital file (p. 509-517)enURBAN AGRICULTUREIRRIGATIONWATER POLLUTIONCONTAMINATIONLETTUCESENEGALURBAN WATER AND SANITATIONWATER RESOURCES MANAGEMENTSOUTH OF SAHARADAKARWASTEWATER REUSEJournal Article (peer-reviewed)
