Can you drink groundwater?

Most of the time, U.S. groundwater is safe to use. However, groundwater sources can become contaminated with germs, such as bacteria, viruses, and parasites, and chemicals, such as those used in fertilizers and pesticides. Contaminated groundwater can make people sick. Water infrastructure requires regular maintenance.

What causes groundwater to rise?

Heavy rains or melting snow may cause the water table to rise, or heavy pumping of groundwater supplies may cause the water table to fall. Groundwater supplies are replenished, or recharged, by rain and snow melt that seeps down into the cracks and crevices beneath the land’s surface.

What are sources of groundwater pollution?

Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land’s surface can move through the soil and end up in the groundwater.

How groundwater is an important source of water?

Groundwater, which is in aquifers below the surface of the Earth, is one of the Nation’s most important natural resources. … It often takes more work and costs more to access groundwater as opposed to surface water, but where there is little water on the land surface, groundwater can supply the water needs of people.

What are the three types of groundwater?

Groundwater is found in two zones. The unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone.

Where is groundwater found?

Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.

How do you find the source of water?

The most obvious sources are streams, rivers and lakes. Animals always know where the water is, so be on the lookout for wildlife or animal tracks. Lush green vegetation is also a sign that water is nearby. Swarming insects may be a hassle, but they also signal that a water source isn’t far away.

What is the example of groundwater?

The water that your well draws from under the ground is an example of groundwater. Water beneath the earth’s surface, often between saturated soil and rock, that supplies wells and springs.

How groundwater is polluted?

Groundwater pollution can be caused by chemical spills from commercial or industrial operations, chemical spills occurring during transport (e.g. spillage of diesel fuels), illegal waste dumping, infiltration from urban runoff or mining operations, road salts, de-icing chemicals from airports and even atmospheric …
