This paper evaluates the level of heterogeneity impact of atterberg limit of the formation; the study analyzed eight locations to determine their plastic limit, liquid limits and plastic index, values generated from different location reflect the behaviour of sand and silty clay base on the experimental data, fluctuation were experiences from 0.2 – 2.5m in all the locations, it generated the lowest   and the highest range from LL30-45, PL, 21-31, PI 9-14, LL 33-44. PL 24-32, PI 9-12, LL 38-44, PL 24-32,PI 9-11, LL38-45, PL, 29-32, PI 9-11, LL 28-44, PI 19-32, PI 9-12, LL 32-45, PL24-32, PI 8-11, LL 30-45, PL 21-31, PI 9-14, LL 38-43, PL 29-32, PI 9-11, LL 28-43, PL 19-31, PI 9-12, LL 33-41, PL 25-30, LL 8-11. The study has determined various values of Atterberg limits in the formation, this evaluation is imperative because it has express the refection of soil heterogeneity of Atterberg limits in sand and silty clay. The generated values are applied for analysis of foundations for an impose loads including pavements design and construction, the values also evaluate the deposition of sand and silty clay in deltaic formation. Moreso the study monitors the plastic behavior of the formation as it is of serious concern to civil engineers.   Because these highly affect construction design, the study has monitor soils with plasticity index that are known to be unpredictable in structural failure base on the volumetric changes in soil by moisture infiltration.
