How do I find out how deep the water table in my area?
The USGS National Water Information System (NWIS) has depth-to-water measurements made in the present and the past. A convenient way to find data for your area is by using the NWIS Mapper and selecting “Groundwater Sites” in the menu on the left.

How do you know if there is water underground?
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.
How deep does a well need to be in Missouri?
In sand and gravel soils, well casings should extend to a depth of at least 20 feet and should reach the water table. For most wells in bedrock, the casing should extend through the weathered zone and into at least 30 feet of bedrock.

Virginia soils can keep water for up to two weeks, before evapotranspiration sucks all the moisture from near the surface. Suburban gardeners and farmers across the state are well aware of the days between rains.
Do deeper wells mean better water?
Well depth can affect both the quality and quantity of water pumped from a well. As shown in figure 2, the quality of water in a well is influenced by the land use activities that take place in its recharge area. As for quantity, a well that is not deep enough to reach the water table will yield no water at all.
How long does it take for rainwater to reach the water table?
The rainfall that seeps into the ground on your property moves through the soil at a rate of only 10 feet per year. Since aquifers (where your well gets its water supply) are hundreds of feet below ground, it might take more than a decade for that rain to reach an aquifer or water-bearing strata!
How far below the surface is groundwater?
Groundwater may be near the Earth’s surface or as deep as 30,000 feet, according to the U.S. Geological Survey (USGS).
