The Minnesota DNR’s drill rig is used for groundwater sampling and can drill up to 150 feet deep, typically with a four- to six-inch diameter. This is the largest drill rig the department owns, and it also has two smaller ones, said Dave Schiller, CAFM, fleet, safety & materials manager.
MnDNR maintains the truck and engine on the rig, but a private vendor does the specialty work and inspections on the rig apparatus.
