Maryland Well Data, Mapped to the Question of Depth

Field notes

The lookup accepts either an address or pasted latitude and longitude, then organizes nearby records by distance and links them to their individual USGS pages. The homepage exposes county-level medians, including 64 feet in Caroline County and 350 feet in St. Mary's County, rather than collapsing Maryland into one statewide number. It also states that the underlying inventory covers only a subset of the state's wells, making the results useful for local context but unsuitable as an address-exact record.
