The ISGS conducts research in many different areas including geologic mapping and energy and earth resources. The drilling team provides assistance wherever they are needed. Sample recovery averages 8,000 to 10,000 feet per year.

In addition, ISGS drillers:

  • install 20 to 30 groundwater monitoring wells per year
  • install piezometers where required
  • perform geophysical logging and GPS on all holes drilled
