How to Hit a Water Table While Mining
The water table is a underground layer of soil lying above an area filled with water called groundwater. Hitting the water table may be a challenge during mining since the process has the tendency to alter the depth of the water table. You should use drill rigs to hit the water table.

Contact your local county officals to research regulations and permit requirements for mining.

2
Determine the depth of the water table in your area. Water table levels are relatively uniform in most areas; however, mining may alter the water table.

Contact your state’s water bureau or local county officals to find information about the water table. County officials have access to the geological data of your area and can advise you about the underground composition of your area (sand, silt, rocks or hard clay) as well as the depth at which you can expect to reach the water table.

4
Use the data to establish the depth of the water below the ground surface as well as the types of rock or soil in your area. This will help you decide on how deep you should drill to hit the water table as well as the type of drill rig you need.

5
Obtain a drill rig. You may have to use augur rigs, rotary rigs or direct push rigs depending on the depth of the water table. Augur rigs are suitable for shallow water tables, while rotary rigs are appropriate when you have to dig through hard clay to access the water table.

6
Place the rig where you wish to drill. Attach the drilling rods or augurs and the drill bit to the equipment according to the manufacturer’s instructions. Leave enough room to fix additional augurs or drilling rods. Most augurs or drill rods are about 5 to 10 feet in length.
-
7
Rotate the rig to drill a hole into the ground. Stop the rig to fix additional drilling rods or augurs once the current one is almost wholly into the ground. Obtain a shovel to remove the drill cuttings from the hole while you drill in case you are using a rotary augur. Keep on fixing additional augurs until you intersect the water table. Once the drill cuttings become very wet, it will indicate you have reached groundwater.
