Tompkins Private Wells Start With Setbacks and a DEC-Registered Driller
Tompkins County’s private-well page gives siting guidance and says to use a DEC-registered well driller.

Tompkins County treats a private well as a site decision, not a simple plumbing detail. The well location should protect drinking water from contamination, with surface water draining away where possible. Separation distances can involve buildings, property lines, septic tanks, sewage systems, and streams, lakes, or wetlands. The driller should be registered with the New York State Department of Environmental Conservation. Those details belong on the map early, while the well location can still move.
That gives the errand a useful split. County health guidance helps frame siting and drinking-water concerns. DEC registration matters for the person doing the drilling. A contractor’s quick reassurance or a real-estate listing is not enough by itself, especially when the property has septic features, old wells, or nearby surface water.
Before a call, gather a sketch or survey, the proposed well location, existing wells, septic features, nearby surface water, property lines, and any clues about unused wells. Then ask Tompkins County health staff or a DEC-registered driller what needs to move before drilling starts. The goal is a clean site decision, not a surprise after closing or after a rig has already been scheduled.
