The study investigates the behaviour of Campylobacter in heterogeneous sand gravel formation. The rate of Campylobacter deposition was monitored in terms of its concentrations in sand gravel deposited formations. This study was found imperative because of high rate of concentration of Campylobacter at different heterogeneous strata. Such conditions were critically evaluated to determine the effect from heterogeneous deposition and migration. The developed model was generated through the derived

At depth ranges of 3-39metres, 2-38metres, and 2-30metres, the concentration of Campylobacter ranges from 47.4-62.6 Mg/L, 32-62.5 Mg/L, and 1.34E-03-2.14E-02 respectively. The system generated several exponential migrating processes, but with different concentrations. The theoretical values were compared with experimental data for model validation and both parameters developed favourable fits. Hence heterogeneity of sand gravel deposition has generated various rates of concentrations reflecting on their migration processes. Experts will definitely apply this concept to observe various rates of Campylobacter concentrations in soil and water environment.
