Answer 2

2 methods of recharging groundwater aquifers are:

• Groundwater is the water available at much depth under the ground. It is supplied to rural areas for irrigation purposes through pumps and a large number of factories are also dependent on these aquifers for water.
• Groundwater is recharged by rainwater but due to the overuse of groundwater for irrigation, it is depleting at a high rate. It is needed to maintain sustainability in some ways are employed.
• Two ways of recharging groundwater are Artificial Recharge and subsurface Recharge.
• Artificial groundwater recharge includes reversing the pond water and basins in the groundwater while subsurface recharge system filling by using wells or some engineering techniques.
