The aquifer is shared
Water pumped from one well can affect neighbours drawing from the same underground store.
About MARVI
Rain moves through soil and rock into an aquifer. Wells reveal only a small window into a connected underground system.

Water pumped from one well can affect neighbours drawing from the same underground store.
Only part of rain reaches groundwater; soils, geology, land use and structures shape the journey.
A single reading is a snapshot. Repeated measurements reveal depletion, recovery and seasonal rhythm.
