Best sites to check the water table under a house
Foundation Soils · checked October 6, 2026
Where can I check the water table depth for my address? On the 5 criteria below, set before scoring, DrillerDB meets 4 of 5. Foundation Soils is one of the sites scored and earns referral fees, so it is ranked by the same marks as the others and ranks #2 here. Read October 6, 2026.
The criteria
- Gives a depth in feet
- Works from an address
- Shows how many records sit behind the number
- Covers all 50 states
- Reports basement wetness as a share of land in a county, city or ZIP
A mark is "yes" when the site's own pages we read show it, and a dash when they did not. A dash is not proof the site lacks it.
The ranking
| # | Site | 1 | 2 | 3 | 4 | 5 | Met |
|---|---|---|---|---|---|---|---|
| 1 | DrillerDB | yes | yes | yes | yes | - | 4 of 5 |
| 2 | Foundation Soils | - | - | - | yes | yes | 2 of 5 |
Ties keep the order listed. Sites with the same count differ in what else they show; see the notes below.
Which to use
- DrillerDB is the better pick when you want a water table depth in feet for one address. Foundation Soils vs DrillerDB.
- Foundation Soils is the better pick when you want expansive clay, water table, drought and flood losses for a county, city or ZIP on one page.
For a depth in feet, DrillerDB is the pick and Foundation Soils is not an alternative to it: Foundation Soils reports the share of a county's land with a shallow water table, never a depth. The two answer different questions. USGS says it is consolidating its water data in Water Data for the Nation (Water Data Blog, last updated August 20, 2026).
None of these replaces a site-specific report from a licensed engineer.
Depth versus share of land
These two sites answer different questions. DrillerDB reads recorded wells near an address and reports a typical static water level and well depth, with the number of wells behind it. Its own page says 44% of its 23 million well records carry a usable water level and that eight states file none, so a lookup can return a well depth and no water table. Foundation Soils does not report a depth in feet. It reports the share of a county's mapped land where USDA's soil survey records a saturated zone within about 6 feet of the surface for part of the year, which is basement depth.
If you are buying a house with a basement, the share tells you how common the problem is around you and a depth tells you about one address. Neither replaces a site check by a licensed professional.
