Answer:
Groundwater during the period of pre-industrial times was less used than in industrial times. People before industrialization lived where they could find easy sources of surface water like rivers, lake, and pond. Majority of the population lived in rural areas where water was easily accessible. The use of water increased during the industrial period because of the no water availability and dirty rivers which were undrinkable in cities and towns. Groundwater increased in industrial times as people began to live in urban areas.
