“…The use of GIS to examine a range of water quality issues has proven useful in past research (Brito et al 2005). Hess (2001) specifi cally examined health risks due to the interaction of shallow ground water and agricultural chemicals using GIS tools in southeastern Pennsylvania.…”

“…For the detection of the extent of water pollution by effluent discharge, we used electromagnetic and electrical methods [12,13,14,15,16,17,18,19,20,21,22,23,24,25,26]. This case study shows that potentially polluting leachates from human activities can be investigated by easy to implement, low-cost techniques [27,28,29].…”

“…The residual water is poured onto the ground outside the wire fence enclosure. The study area has a moderate degree of vulnerability to the contamination of groundwater, as concluded after applying the DRASTIC method (Figure 2), so that discharges can adversely affect the water quality and contaminate aquifers [14,15,16,17,18,19,20,21]. …”

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.

“…The type of soil determines the extent to which nitrates are leached, by influencing the surface flow and infiltration rate (Brito et al, 2006;Lencastre and Franco, 2006;Silva and Almeida, 2009). More permeable formations like sand, gravel and karst are more likely to conduct large amounts of water and leach pollutants such as nitrates.…”
