Objective: The present study assesses the quality of
undeveloped spring water consumed directly by the local population of the
province of Kasaï in the D.R. Congo in order to satisfy sustainable access to
drinking water in the province of Kasaï.
Materials and Methods: This study was conducted in the
province of Kasai, in the villages of Kamupafu, Kabilowa, Kayonga, Kankondo,
Kankala, Lunyanya and Kumbikumbi in the town of Tshikapa. The study covered the
period from September 29 to October 24, 2022.
The water samples taken (27) were prepared in the laboratory
according to standard procedures and a series of physico-chemical and
microbiological characterization analyzes were carried out in the field and in
the laboratory. The data collected was processed and analyzed using SigmaStat
11.0 statistical software.
Results: Among other results obtained, it appears that the
average pH was between 4.6±0.15 and 6.96±0.43; the EC between 12.91±0.51
µS.cm-1 at the Dido/Milonga spring and 26.87±3.00 µS.cm-1 at the Tshitenga
spring. The turbidity, the soluble ion (NO3-, F-), and arsenic (As) contents in
the water reveal that with the exception of the turbidity in the Kamitutungulu
spring (10 ± 1.04 NTU), the concentration of the other elements in the water
from all the springs studied complies with WHO recommendations for drinking
water quality. In addition, the average values (CFU 100 mL-1) of total
coliforms vary between 18 (KAMANKONDE/ROBERT) and 81 (KATOKA 3) for the water
of all the springs.
Conclusion: Scientific support is therefore suggested for
the various actions carried out by numerous organizations or research centers
in terms of drinking water supply and hygiene through the establishment of
village water supply structures, communication for a change in behavior and
socio-economic actions in favor of disadvantaged grassroots communities in a
sustainable perspective.
