Using Turbidity as a surrogate of viscosity in real-time bacteriological water quality assessment at a catchment point: A Case Study of Dang wells

Abstract

Turbidity is successful in tracking the movement of various constituents or parameter distribution through a
water body plan. This soil particles, algae, suspended solids, flocs or simply turbidity cause materials (TCMs)
movement, can modify the flow resistance. Such fluid (water) with complete environment mixing and the
concentration after mixing characterizes flocs and particles at their surface. It is the linkage of pathogens germs
with their growth to TCMs, that can help estimate bacteria existence. This paper use bacteria attachment to
TCMs thorough continuous turbidity monitoring as a relevant rheological (viscosity) parameter surrogate to
characterize bacteriological water quality loads in real time at the catchment point. Its innovation aimed to
assess the microbiological water quality sampled from domestic water sources. The sampling is done in
Adamawa region of Cameroon, from twenty (20) Wells aseptically in the lieu-dit of Dang. At each sampling
point, 1000 mL is taken and immediately transported to the laboratory for analysis and in situ tests measure of
turbidity is done. The detection of Coliforms bacteria was done using Micro Biological Survey (MBS) method.
1 mL of each sample was inoculated in the Coliforms MBS (Coli MBS) vial initially rehydrated with 10 mL
of sterile distilled water. From the in-situ turbidity measures we estimate the viscosity thorough the model and
analyzed variations of bacteria in each well corresponding to the turbidity and the corresponding viscosity
