This study in Fez, Morocco, compared bacteriological and parasitological contamination in urban, peri-urban, and rural irrigation waters, and their transfer to soil and crops (cardoon and eggplant). Investigated microorganisms included total and thermotolerant coliforms, helminth eggs, Salmonella, and cholera vibrio. Results revealed contamination exceeding national and international standards for both types of coliforms in treated wastewater (TWW), wastewater (WW), Oued Fez water, and upstream well water in both winter and summer. This fecal contamination was found in soils and crops irrigated by urban and peri-urban water. Helminth eggs and cholera vibrio were also present in these waters, soils, and crops, with Salmonella detected in TWW in summer. Only the plot irrigated with Oued Bitit water in the rural zone met standards across all three levels of irrigated water, soil, and plants, and in both periods.

This synthesis paper summarizes current scientific knowledge on lead (Pb) contamination in urban garden soils and provides clear recommendations for assessing actual health risks and limiting exposure. Urban garden soils often contain elevated levels of Pb, mainly from legacy sources, which is a main barrier for urban gardening. Amendments are noted as unreliable for treating contaminated soils to reduce risk, as they do not always make contaminants less harmful.
