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.

Rock cuttings were collected in 2009. A total of 9 Bedrock monitoring wells were drilled in 5 different formations. Cuttings were collected every 20 feet during drilling. The deepest well was 480 feet. Rotary drilling was the drilling technique used, which produces varying sizes of rock chips. Cuttings were collected and major minerals and the bedrock formations were identified on-site by geologists. Cuttings were bagged, and labeled with all pertinent metadata. A well log was maintained during drilling, and this information may be included in the metadata for the cuttings. Bedrock monitoring well cuttings obtained in 2009

A vast collection of geologic reports (bedrock and surficial) including, but not limited to, bulletins and resource surveys, most with accompanying quadrangle or field maps. Publications date back to the 1950's and include a comprehensive geologic history of the mapping area. A large percentage of these publications are out of print and do not exist in any other form. Some are rare publications, which exist only in the State Geologist's archive. Most of these maps and reports were published by the Department of Resources and Economic Development (DRED) and the New Hampshire State Planning and Development Commission. Geologic information included in these publications has not be reproduced elsewhere, and is only...

This collection is a combination of mostly quad maps (scale 1:62,500), and other miscellaneous maps containing notes and drawings of bedrock delineations. A collection of maps with hand-drawn bedrock geologic data used to create the Bedrock Geologic Map of New Hampshire (Lyons and others, 1997).

The collection of Highway Maps includes 8 NH counties at a scale of 1:31680. Maps have shaded areas denoting specific geology in each county. Highway maps ranging from 1958 to 1963. To our knowledge, this set is complete in its current state. Counties are missing, but there is not a discernible way to retrieve them.
