Connecticut Well Data, with 6,179 wells to look up
A public-data interface for exploring Connecticut groundwater-well depths, locations, aquifers, and completion dates by address or map coordinates.
Field notes
The interface starts with an address or pasted map coordinates, then organizes nearby USGS groundwater records by distance and measured depth. Its regional overview exposes substantial variation: the listed medians range from 44 feet in Greater Bridgeport to 145 feet in the Lower Connecticut River Valley. The site also displays a 120-foot statewide median and a 300-foot depth threshold for nine out of ten wells, while warning that the inventory is not a complete address-level record of every Connecticut well.
