This collection includes: Water wells, monitoring wells and geothermal wells.
The New Hampshire water well inventory database was initiated in 1984 in conjunction with the passage of state statute RSA 482-B which requires licensing of water well contractors and the submission of well completion reports. These reports provide a record of basic construction details of each well along with general information describing geologic materials and subsurface conditions at the well site. A sustained effort has been made to accurately locate each well on a map and store its location in digital form in a geographic information system (GIS). GPS technology was employed to georeference wells beginning in 1995.
