The Geological Survey Program is organized into three sections that perform the following major functions:

  • The Geologic Resources Section fulfills many of the traditional tasks of the Geological Survey. It acquires and maintains basic geologic data that are used by the other sections and provides technical assistance to both the private and public sectors. Staff Listing
  • The Environmental Geology Section conducts field investigations and provides services in determining the environmental hazards posed by waste disposal practices and spills. Staff Listing
  • The Well Installation Section ensures that any new private water well (this includes domestic and multiple family class wells) is constructed to minimum standards as set by the state regulations. The section regulates the construction of private water wells irrigation wells, monitoring wells and heat pump wells. In addition, we regulate how to properly plug all types of wells. Staff Listing
