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.
Why is underground water usually safe for drinking?
Generally, both ground water and surface water can provide safe drinking water, as long as the sources are not polluted and the water is sufficiently treated. ... Ground water is, in general, easier and cheaper to treat than surface water, because it tends to be less polluted.
What happens if you drink groundwater?
Drinking contaminated groundwater can have serious health effects. Diseases such as hepatitis and dysentery may be caused by contamination from septic tank waste. Poisoning may be caused by toxins that have leached into well water supplies. Wildlife can also be harmed by contaminated groundwater.
Why do we say that underground water is clean?
Groundwater sources are found within certain layers underground called “aquifers”. The various strata of soil, sand, and gravel found underground filter out most disease-causing organisms and harmful chemicals as the water infiltrates through them . This is why groundwater can be considered a clean water source.
Is underground water everywhere?
Groundwater is everywhere beneath the soil surface and can be ever-present in many places if allowed to recharge. ... Groundwater has been an extremely important source of water for many years, especially in arid climates.
Do we drink 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.
Why groundwater is bad?
Groundwater is found below the earth’s surface and includes water from bores, springs, wells and other sources. There are risks involved in using groundwater. Groundwater may contain disease-causing microorganisms which can cause illness. ... This can release harmful metals such as lead and copper into the water.
How deep does groundwater go?
Groundwater may be near the Earth’s surface or as deep as 30,000 feet , according to the U.S. Geological Survey (USGS).
Is groundwater the cleanest water?
Unlike surface water collected in rivers and lakes, groundwater is often clean and ready to drink . This is because the soil actually filters the water. The soil can hold onto pollutants—such as living organisms, harmful chemicals and minerals—and only let the clean water through.
Why groundwater is pure?
Groundwater is pure and hence a very safe source . ... Groundwater is not connected to rivers and lakes. Contaminants from oil that is poured on the ground will be filtered by soil and gravel before reaching groundwater. If a well reaches groundwater, an unlimited amount of water can be pumped.
How much underground water is there?
| Water source Water volume, in cubic miles Percent of total water | Groundwater 5,614,000 1.69 | Fresh 2,526,000 0.76 | Saline 3,088,000 0.93 | Soil Moisture 3,959 0.001 |

What are the source of underground water?
Groundwater sources are beneath the land surface and include springs and wells . As can be seen from the hydrologic cycle, when rain falls to the ground, some water flows along the land to streams or lakes, some water evaporates into the atmosphere, some is taken up by plants, and some seeps into the ground.
Can underground water be detected?
The ground penetrating radar (GPR) system is used for underground water detection. GPR is a promising technology to detect and identify aquifer water or nonmetallic mines. One of the most serious components for the performance of GPR is the antenna system.
Where is most underground water?
The groundwater contained in aquifers is one of the most important sources of water on Earth: About 30 percent of our liquid freshwater is groundwater, according to the National Oceanic and Atmospheric Administration (NOAA). The rest is found at the surface in streams, lakes, rivers and wetlands.
Will we ever run out of water?
While our planet as a whole may never run out of water , it’s important to remember that clean freshwater is not always available where and when humans need it. ... More than a billion people live without enough safe, clean water. Also, every drop of water that we use continues through the water cycle.
How old is water that we drink?
The water on our Earth today is the same water that’s been here for nearly 5 billion years .
