U.S. Water-Well Statistics by State

Name: U.S. Water-Well Statistics by State
Creator: DrillerDB
License: https://drillerdb.com/data/license

This page reports geography-based statistics for water wells across the 50 U.S. states: how many well-completion records are on file in each state and the typical (mean) depth wells are drilled to. The figures are derived from the DrillerDB well records dataset, a compiled database of 18,029,601 North American water-well records built from public well-completion and well-log records. That North American total spans 50 U.S. states and 6 Canadian provinces and was verified against the database on 2026-07-02; this page focuses on the 50 states. The per-state figures are a snapshot recomputed on 2026-07-02. Every number below is an aggregate. The page contains no company-level, owner-level, or driller-activity data.

Typical well depth by state

The table lists the typical (mean) completed depth of water wells in each state and how many records are on file, sorted from deepest to shallowest. Local geology can shift these figures by hundreds of feet, so treat them as regional baselines. Alabama, Hawaii, and West Virginiashow "n/a" for depth: their samples are dominated by oil-and-gas logs or too small to publish a reliable average, so only the record count is shown.

For journalists

Headline-ready facts, each derived from the per-state data on this page. The figures are aggregates and carry no individual, company, or owner detail.

DrillerDB holds water-well records for all 50 U.S. states.
Across the 50 states, DrillerDB has 16,108,916 well records on file (2026-07-02 snapshot). The full North American dataset holds 18,029,601 records across 50 U.S. states and 6 Canadian provinces as of 2026-07-02.
The state with the most records on file is Florida, with 1,839,284.
Typical residential well depth varies widely by geology, from about 74 ft (Washington) to about 417 ft (Wyoming) across states.
The average of the state typical depths is about 216 ft, across the 47 states with a reliable depth figure.
Alabama, Hawaii, and West Virginia do not have a publishable typical depth because their samples are dominated by oil-and-gas logs or are too small, so DrillerDB shows a record count only for those states.
