Mapping of Water Resistivity Using Pool Water

Resumo

The relationship between the resistivity (conductivity) of soil and that of pore water was stated in papers by G.E. Archie and V.N. Dakhnov. This means that water resistivity should be studied at each fieldwork area. In some areas, however, the access to groundwater (boreholes, wells, and springs) as well as to the surface reservoirs (rivers, brooks, ponds, and lakes) is not possible or is restricted. Can we measure water resistivity in pools? Immediately after a rain such water has no relationship with soil resistivity. The purpose of this work was to study the pattern of ion exchange between soil and rain water over time. In (Brunet et al., 2010) the changes in resistivity of water in contact with soil over time were measured. We have verified their results.
