Kriging - Opis:
- The groundwater physico-chemical parameters of Parts of Akwa Ibom state and their spatial distribution have been examined in this study. The physico-chemical parameters analysed are Ph, total dissolved solids, electrical conductivity and water hardness. The average pH, electrical conductivity, water hardness and total dissolved solids obtained are 6.4, 163.4242 μS/cm, 83.81 mg/l and 90.5 mg/l respectively. The computed values are within the permissible limit set by World Health Organisation (WHO). Semi-variogram and ordinary kriging were used for the spatial distribution analysis. The semi variogram of the pH, total dissolved solids, electrical conductivity and water hardness were model with Gaussian, spherical, linear functions respectively. The pH map is dominated with values ranging from 6.2 to 6.6 while the total dissolved solids map is associated mainly with values ranging from 90 to 95 mg/l. The water hardness and electrical conductivity values increases from central part toward the west and eastern regions. The geostatical modelling has been used to estimate the values of the parameters at unsampled points.
