Soil-Survey Water-Table Depth by Address
Review USDA mapped-unit water-table depth indicators at a selected location, with the source limitations kept visible.

A survey indicator, not a well measurement
These values summarize soil-survey conditions for a mapped unit. They are not groundwater measurements taken at the address and should not be presented as exact parcel water-table depth.
Annual versus April–June indicators
The two survey summaries can represent different seasonal windows. Both are historical mapped-unit indicators rather than live groundwater readings.
Why field conditions differ
Weather, drainage improvements, excavation, fill, and local relief can change conditions at a specific point. A monitoring well or site investigation answers different questions.
Why a property can show multiple results
The address resolves to a point inside a USDA map-unit polygon. That unit may contain several soil components in reported proportions, and the selected square foot is not directly sampled. The lookup therefore displays component percentages, attributes, and uncertainty together.
Source and limitations
Results come from USDA NRCS Soil Data Access and SSURGO after location matching through the U.S. Census Geocoder. Use them for research and screening, not as a replacement for field sampling, engineering, permitting, wetland delineation, or a septic perc test. Read the full methodology and data-source notes.
