Geochemical and Geophysical Study in a Degraded Area Used for Disposal of Sludge from a Water Treatment Plant
Figure 2
Geophysical surveys in the gravel pit. The central spots correspond to the plume resulting from the chemical sludge in the study area. (a) Horizontal mapping, highlights in white correspond to collection points located in the WTS disposal area. (b) Vertical electric sounding, especially emphasis is given to the area between 150 and 300 meters, where there is the sludge disposal. Graphic scales are different due to different times during data collection.
