Answer:
True
Explanation:
Some amount of the rain water gets penetrated inside the ground, this water is termed as underground water. This process of seeping of water helps the underground water to get recharged time to time. Melting of the snow also helps in the addition of the underground water. The level of underground water is recharged and is further used for other purposes. The permeable soil and rocks helps the water to seep through the pores and reach the groundwater. In this process it is purified naturally.
