What is the greatest use of groundwater as drinking industry Agriculture recreation?
The correct answer to the question above is: (c.) agriculture. Agriculture is the greatest use of groundwater.
What is the importance of groundwater and its greatest use?
Groundwater, which is in aquifers below the surface of the Earth, is one of the Nation’s most important natural resources. Groundwater is the source of about 33 percent of the water that county and city water departments supply to households and businesses (public supply).
What is the greatest use of ground water?
Saline groundwater withdrawals were predominantly used for mining (80 percent) and occurred in Texas, California, and Oklahoma. Irrigation used greater than three times more fresh groundwater than public supply, which was the next largest use of fresh groundwater in the Nation.
What is the uses of groundwater?
Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. Groundwater helps grow our food. 64% of groundwater is used for irrigation to grow crops. Groundwater is an important component in many industrial processes.
What industry uses the most groundwater?
In 2015, the main uses for groundwater in the United States were irrigation (68%) and public supply (18%). Although over 13 million households in the United States get their water from private wells,3 this accounts for only 4 percent of all groundwater used in the United States.
What state uses the most groundwater?
Groundwater use is highest in parts of the country with limited rainfall but high water needs, especially for irrigation. Which areas in the United States are most dependent on groundwater?
|U.S. Virgin Islands||50%|
Is groundwater drinkable?
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.
Why is it important to manage groundwater?
Globally, groundwater is an essential freshwater resource for both socioeconomic and environmental systems, and forms a critical buffer during periods of drought. This makes the protection of groundwater supplies – through management, pollution control and remediation – essential.
Why is it important to protect groundwater?
Furthermore, many public water systems draw all or part of their supply from groundwater, so protecting the resource protects the public water supply and impacts treatment costs. Protecting groundwater will help reduce risks to your water supply.
Who uses the most groundwater?
Irrigation accounts for the largest use of groundwater in the United States. Some 57.2 billion gallons of groundwater are used daily for agricultural irrigation from 475,796 wells.
Which country has the most groundwater?

How do I know where my ground water table is?
The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.
What is the main source of groundwater?
The main (and frequently only) source of groundwater is precipitation. Water falling on the surface is absorbed into the ground and slowly filters
What are the types of groundwater?
Aquifers are divided into two types: unconfined and confined. An unconfined aquifer is often shallow, and the vadose zone above it primarily contains permeable material. The top of the aquifer is the water table.
What are the 3 zones of groundwater?
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. The top of the saturated zone is called the water table (Diagram 1).
