Three main types of pollution are not present in the natural creek:
- indoor air pollution with including discharges of sewage, garbage dumps or the leaching of waste by the rain ...
- including agricultural pollution due to livestock excreta, and the use of pesticides and fertilizers by farmers. This type of pollution is still very low on our study area.
- industrial pollution: pollution that occurs primarily in the industrial zone Mbao. Indeed, a tannery factory discharges its wastewater into a canal that enters the creek. In this section, the creek is highly degraded with water colors pink and green represents an enormous environmental and health risk.
