Mining Better Data at Lower Cost — Fully Grouted Piezometers Valuable for Groundwater Investigation at Mines 

Water is a critical resource for mine operations.  Hydrogeologic assessments help mine operators understand potential water supplies available and how to convey that supply to where it’s needed. Thorough characterization of groundwater conditions is particularly important when a groundwater computer model must be developed for mine permitting purposes. Without the right technology and expertise, these …
