    Low-Flow Purging and Sampling Training Courses

    Have you ever wondered if there is a better method than you are currently using for collecting more representative water-level data and ground-water samples from your wells? Ever thought about all of the various sources of bias and error in water-level measurement and sample collection procedures and wondered how each could affect the data in your sampling program? This series of 2 modules provides an in-depth discussion of how water-level measurement...

    Field Parameter Measurement During Well Purging Training Courses

    Measurement of field water-quality indicator parameters is a fundamental component of most conventional purging and all low-flow purging and sampling approaches to collecting ground-water samples from monitoring wells.  This module explains how to correctly measure the most common water-quality indicator parameters (including pH, specific conductance, dissolved oxygen and redox potential) and physical parameters (temperature and turbidity) used...
