  "id": "MLC-T-MET-003636",
  "term": "Artesian aquifer",
  "field": "Meteorology and atmospheric science",
  "definition": "A confined aquifer where groundwater is under sufficient pressure to rise above the top of the aquifer in a well, without the need for pumping. This occurs when the aquifer is sandwiched between impermeable layers and recharged at a higher elevation. The water level in an artesian well, if not flowing freely, will rise to a potentiometric surface above the aquifer's upper boundary.",
