 Location Duration was conducted Kasai, villages Kamupafu, Kabilowa, Kayonga, Kankondo, Kankala, Lunyanya Kumbikumbi town Tshikapa. The covered period from September 29 October 24, 2022.
 Methodology: samples taken (27) were carried out laboratory according standard procedures series physico-chemical microbiological characterization analyzes also field laboratory.
 Results: Among other obtained, it appears that average pH between 4.6±0.15 6.96±0.43; EC 12.91±0.51 µS.cm-1 at Dido/Milonga 26.87±3.00 Tshitenga spring. turbidity, soluble ion (NO3-, F-) arsenic (As) contents reveal exception turbidity Kamitutungulu (10 ± 1.04 NTU), concentration elements all springs studied complies WHO recommendations for drinking quality. In addition, values (CFU 100 mL-1) total coliforms vary 18 (KAMANKONDE/ROBERT) 81 (KATOKA 3) waters springs.
 Conclusion: All analyzed showed contamination bacteria indicating faecal pollution (coliforms). It’s therefore suggested support be provided terms supply hygiene setting up village structures.
