Where is a aquifer located?
Groundwater can be found in a range of different types of rock, but the most productive aquifers are found in porous, permeable rock such as sandstone, or the open cavities and caves of limestone aquifers.
Can you drink water from an aquifer?
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.
Is aquifer water good?
Aquifers are critically important in human habitation and agriculture. Deep aquifers in arid areas have long been water sources for irrigation (see Ogallala below). Many villages and even large cities draw their water supply from wells in aquifers.
Does every state have an aquifer?
Unlike surface water, which is mostly found in the northern and eastern parts of the state, aquifers are widely distributed throughout California. Additionally, they are also often found in places where freshwater is most needed, for instance, in the Central Valley and Los Angeles.
What state has the largest aquifer?
The Ogallala Aquifer is the largest aquifer in the United States. It is part of the High Plains aquifer system, which underlies parts of eight states from Texas to South Dakota.
How do you find an underground aquifer?
Sand or gravel areas in the bottom of valleys will often be home to groundwater. These layers can be covered by clay or silt, so it’s prudent to check these areas thoroughly. Natural springs usually indicate groundwater is nearby. A spring that flows year-round will likely reveal a productive aquifer.

What happens if you pump too much water out of an aquifer?
Pumping too much water too fast draws down the water in the aquifer and eventually causes a well to yield less and less water and even run dry. In fact, pumping your well too much can even cause your neighbor’s well to run dry if you both are pumping from the same aquifer.
How long does it take aquifers to recharge?
In general, it takes several years of average or above-average precipitation to recharge aquifers in California to pre-drought levels. When it comes to recharge, the individual basins vary greatly.
Where do aquifers get their water from?
An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil.
