The troubles in California create an interesting case study. That state's water system is highly unsustainable. It is plumbed to bring water from the wet north and east to the megalopolis of southern California where residents reside in a desert that receives about 10 inches of water a year. Such a setting leaves residents vulnerable to drought and sets the stage for regional water conflict.
While Long Island does receive an abundant rainfall, its coastal setting leaves it vulnerable to salt water intrusion. More significantly, because the entire population draws from a single aquifer with direct contact to the surface, Long Island is highly susceptible to groundwater contamination.
