Some were dissipating water until they dried out, others, initially due to the lack of sanitation, the creation of domestic pits that were polluting the subsoils and contaminating the waters, later with the uncontrolled pollution of the soils through pesticides and strong excrements, many of these natural water resources ceased to be used because they were registered as unfit for consumption (polluted water) or uncontrolled water.
The new generation no longer risks considering a fountain potable if nothing is warning on its headstone as fit for consumption or drinking water.
