In 2017, the Iowa Geological Survey (IGS) obtained a new drill rig for groundwater monitoring, soil health studies, geologic mapping, and more.
The IGS maintains a #35-SCS Giddings drilling machine mounted on a RAM 5500 truck. The drill is capable of continuous core sampling with a hollow stem auger system to 50 feet, as well as solid stem flight auger sampling to the same depth. The drill is also equipped with a “direct push” hydraulic soil sampling system. The drill is further capable of performing well pump tests to 300 feet. Matthew Streeter is a soil scientist at the Iowa Geological Survey and an Iowa-licensed well driller. He is responsible for the operation and maintenance of the IGS drill rig.
