These names and some of the municipality's nicknames such as Ciudad de las Aguas Claras ("city of clear waters") and Oasis de Puerto Rico ("Puerto Rico's oasis") are a reference to the number of natural water springs that can be found in the municipality, particularly those founds around the Aguas Buenas Cave and Caverns System Nature Reserve (Spanish: Reserva Natural Sistema de Cuevas y Cavernas de Aguas Buenas).
