The water table can lower due to increased pumping of groundwater for irrigation or drinking water, drought conditions reducing recharge rates, or land use changes that affect infiltration rates. Climate change can also play a role by altering precipitation patterns and increasing evaporation rates.
The lowering of the water table that occurs when water is pumped from a well is called "cone of depression." This phenomenon happens because the pumping creates a cone-shaped cavity in the groundwater, causing the water table in the immediate vicinity of the well to drop.
the cone of depression
The lowered surface in the water table around a well is called a cone of depression. It is caused by the pumping of water from the well, which creates a temporary lowering of the water table in that specific area. The cone of depression will become larger if there is excessive pumping from the well or if the water table is already low, and will become smaller if pumping is reduced or if the water table is replenished through natural recharge.
Increased use of water by a growing population can deplete the underground aquifer and lower the water table faster than it can be naturally replenished.Extended drought over the recharge zone can prevent an aquifer from replenishing its water supply.

Since the time period fits the main industrial growth of the area it could be over-extraction or mining causing the lowering of the water table.

the reasons are : 1)over population-increase in population has caused an increase in the amount of water used in agricultural fields, industries and domestic uses 2)sewage- the improper channelising of sewage water also results in an increase in polluted water that cannot be used anymore and so it is also like depletion
As the water table around the world is lowering at a rapid pace, without conservation there would be no water left for day-to-day uses.
A lowering of the water table most likely occurs during periods of prolonged drought or reduced precipitation, which decreases the recharge of groundwater. Additionally, excessive groundwater extraction for agricultural, industrial, or municipal use can lead to a significant drop in the water table. Other contributing factors may include increased evaporation rates and land development that disrupts natural water flow.
the cone of depression
During a drought, the water table typically drops as there is reduced replenishment of groundwater from precipitation. This can lead to wells and aquifers drying up, impacting water availability for drinking, agriculture, and ecosystems. Additionally, prolonged droughts can result in long-term lowering of the water table and increased risk of subsidence.
