Environmental Drilling Technology for Site Characterization and Monitoring Well Installation Training Courses
From Complete Groundwater Monitoring E-Course
There are more than a dozen different drilling methods that may be used to drill boreholes to collect soil samples for site characterization and install monitoring wells, but which method is most appropriate for your project? This series of 2 modules provides a detailed discussion on how to effectively evaluate and select the best drilling method for anticipated site conditions that will meet site-specific project objectives. Each of the most commonly used drilling methods is described in detail with respect to their operational characteristics and their applications and limitations for environmental site characterization and monitoring well installation. Field video is included at the end of the first module to explain the principles and practices employed in sonic drilling. While you may opt to take just one of these modules, it is strongly recommended that you take both modules in the prescribed order if you want comprehensive coverage of the subject.
