The median residential well in Rensselaer County is 320 ft deep, based on 3,811 completion reports filed with the New York State Department of Environmental Conservation. Most fall between 146 and 502 ft; the deepest on record is 1022 ft.

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.
