drinking water. Table 6.1 demonstrates that several billion individuals mainly
depend on groundwater to use for drinking water.
Numerous nations in the world uses groundwater for the purpose of drinking
water as a main source (Table 6.2). Sadly, it was identified that Africa is utilizing the
little quantity of groundwater for drinking purpose. Table 6.2 demonstrates that
groundwater is broadly utilized for drinking water in Europe, particularly in Denmark which generates 100% of the drinking water from groundwater. In provincial
regions of India and the United States, groundwater additionally signifies to the
essential source of consumable water (80% and 96%, respectively). In Tunisia,
groundwater signifies 95% of the nation’s water requirements, 83% in Belgium,
and 75% in the Germany, Netherlands, and Morocco. In most European nations
(Belgium, Austria, Hungary, Denmark, Switzerland, and Romania) groundwater
usage surpasses 70% of the complete water utilization (Vrba and van der Gun
2004). In numerous countries, the greater part of the well-drawn groundwater is
for household water supplies which gives 25 to 40 % of the earth’s drinking water
(Lambrechts et al. 2003).
