How Deep Are Wells in Rockland County, NY?
The median residential well in Rockland County is 225 ft deep, based on 486 completion reports filed with the New York State Department of Environmental Conservation. Most fall between 145 and 430 ft; the deepest on record is 1065 ft.
That is 27 ft deeper than the New York state-wide average of 198 ft (an n-weighted average across every New York county with reported data). Depth depends on local geology, your own site could sit well outside Rockland County's typical range.
Source and method: New York State Department of Environmental Conservation water well completion reports (NYS GIS Clearinghouse), extracted 2026-07-14. Figures include only wells recorded as residential (domestic) use, with a reported depth between 15 and 2,000 ft (to exclude likely data-entry errors). This dataset carries no completion date, so figures cover all domestic wells on record rather than only recent ones, and DEC notes the driller-submitted data are in most cases not verified. These are figures self-reported by licensed drillers to the state; treat this as a planning reference, not a guarantee for any specific property.
