Distance from the sea is the factor among the given options that does not universally affect the distribution of groundwater.

Groundwater distribution is primarily controlled by factors related to the supply of water and the ability of the ground to store and transmit it. These include the amount of precipitation (recharge), the rate of evaporation (loss and reduced recharge), and the geological characteristics (porosity, permeability, infiltration capacity). Distance from the sea is relevant mainly for coastal hydrogeology (e.g., saltwater intrusion) but is not a fundamental factor governing groundwater distribution in all landscapes, particularly inland areas.

Precipitation is the main source of groundwater recharge. High evaporation rates reduce surface water and soil moisture, limiting infiltration. The ability of the ground surface (and underlying strata) to allow infiltration and hold water determines where groundwater can accumulate and how it is distributed in aquifers. While distance from the sea influences specific conditions like salinity gradients and tidal effects in coastal aquifers, it doesn’t determine the general presence or absence and distribution of groundwater in non-coastal regions, which are governed by climatic and geological factors.
