Abstract

As part of a sustainable development approach, this study analyses the impact of anthropogenic activities on the water quality of Lake Kabongo (Kolwezi, DRC) before and after their removal. Physicochemical and biological analyses were carried out from November 2024 to March 2025. The results reveal a significant improvement: turbidity fell from over 69 NTU to around 62 NTU, and the microbial load fell from 1230 RLU to 486 RLU. This confirms the effectiveness of sanitation measures such as dredging, awareness- raising and flow redirection, and establishes this model as a benchmark for the restoration of impacted aquatic ecosystems.
