RONGOĀ must have a highly unusual interior structure, because drilling a well in almost any new location results in a gigantic geyser of fresh water, under such high pressure that most of it actually escapes into the atmosphere.  After some time, the plume exhausts itself and produces no more.  Upon discovering this, Rongoāns proceeded to create many such ephemeral springs to irrigate their crops, slake their thirst, or just produce a beautiful spectacle to be enjoyed.  Unfortunately such profligate drilling has left Rongoā thoroughly pock-marked, and some regions are now actually quite parched.  Conservation efforts are trying to more proactively manage the planet's water resources, but face considerable resistance from those accustomed to drilling wherever they like.
