Resumen
[EN]The present work envisages the possible geometry of a contaminated plume of groundwater
near hospital facilities by combining GIS (Geographic Information System) and geophysical methods.
The rock underlying the soil and thin sedimentary cover of the study area is moderately fractured
quartzite, which makes aquifers vulnerable to pollution. The GIS methodology is used to calculate
the area that would be affected by the effluent source of residual water, based on algorithms that
consider ground surface mapping (slopes, orientations, accumulated costs and cost per distance).
Geophysical methods (electromagnetic induction and electric resistivity tomography) use changes in
the electrical conductivity or resistivity of the subsurface to determine the geometry of the discharge
and the degree of contamination. The model presented would allow a preliminary investigation
regarding potential corrective measures.
