Parasitic study of wastewater discharging in Boufekrane river at the collector of the Agdal district (Meknes, Morocco): inventory and monitoring

1The Boufekrane River crosses the city of Meknes from south to north and is a place of discharge of urban wastewater. This oued is a significant source of water for irrigating vegetable crops at neighboring farms. In the absence of treatment of this wastewater, the impact on public health could not be without danger. The objective of this work is to evaluate the degree of parasitic contamination of wastewater discharging directly on the Boufekrane River and its fluctuation during the daytime. For this aim, a parasitological monitoring is carried out in the collector of "Agdal" district, located in the urban center of the city of Meknes. Samples were taken every 2 hours from 08:00 to 18:00 and processed by Arther Fizerald Fox's flotation concentration method. The results showed the presence of a variation of the parasite load during the day with a maximum observed between 12:00 and 14:00 and a minimum between 16:00 and 18:00. Twenty species have been identified. The study also showed that nematodes constituted 51% of parasite eggs followed by protozoa (35%), cestodes 11% and finally trematodes 3%.
