What is the significance of groundwater?
Groundwater helps grow our food. 64% of groundwater is used for irrigation to grow crops. Groundwater is an important component in many industrial processes. Groundwater is a source of recharge for lakes, rivers, and wetlands.
How does groundwater do geologic work?
To reach an aquifer, surface water infiltrates downward into the ground through tiny spaces or pores in the rock. The water travels down through the permeable rock until it reaches a layer that does not have pores; this rock is impermeable (figure 1). This impermeable rock layer forms the base of the aquifer.
What is the significance of groundwater for plants?
From there, the water either runoffs to surface water (streams, rivers, lakes, oceans) or soaks into the ground where it might evenutally become groundwater. Soil is where plants grow. Plants are important because many serve as food and shelter for animals and humans…..
What is the importance of groundwater for human beings?
Groundwater is a prime natural resource in the Earth. It not only supports all types of life forms to exist in the Earth but also helps in the growth of human civilization. It quenches thirst and fulfils all the house-hold demands. Groundwater is used for the irrigation purposes.

What are the 5 effects of water pollution on the human body?
Contaminated water can harbor bacteria, such as those responsible for diarrhea, cholera, dysentery, typhoid, hepatitis A, and polio. According to the UN, every year, approximately 297,000 children under five die from diseases linked to poor sanitation, poor hygiene, or unsafe drinking water.
What are main sources of water pollution?
The main point source of pollution to water is from sewage and waste water treatment, while for diffuse pollution, main sources are from farming and fossil fuel power plants (via the air).
What are the types and sources of water pollution?
Direct sources include effluent outfalls from factories, refineries, waste treatment plants etc.. that emit fluids of varying quality directly into urban water supplies. Indirect sources include contaminants that enter the water supply from soils/groundwater systems and from the atmosphere via rain water.
