Klint Gingerich and his brother, Korwin, are co-owners of Gingerich Well and Pump Service, a family-owned and operated business. . Tooling up for DTFR requires a substantial investment to begin: a suitable rig, in-hole tools, shale shakers, and a compressor. And the economics associated with DTFR technique only begin. RC technology aids in installing groundwater monitoring wells and collecting soil samples for contamination studies. Its precision helps track pollutants and design remediation strategies. In mining operations, RC drills create blast holes for controlled explosions. [pdf]
