Overview of the water purpose of the groundwater wells in the database. (a) Each point on the map represents the recorded location of a well. Blue dots represent wells constructed for domestic or public water supply (DOM), green dots for agriculture/ livestock (AG) and red dots for industry (IND). Mixed colors represent wells with more than one use (e.g., DOM & AG; DOM, AG & IND). Wells without an indication of purpose are not shown. The fraction of wells per purpose in Brazil is shown, with the majority primarily dedicated to domestic or public water supply. (b) Well capacity by purpose, indicates that wells for agriculture have the highest average capacity. (c) Box plots indicate 25th and 75th percentiles, bars represent 10th and 90th percentiles, solid horizonal lines indicate median, and x marks mean values. The dark black lines delineate the geographic regions of Brazil, the lighter black lines represent the Brazilian states and the federal district.
