The Purge Analyzer Tool (PAT) to Assess Optimal Pumping Parameters in the Collection of Representative Groundwater Samples from Wells

The U.S. Geological Survey in cooperation with the U.S. Environmental Protection Agency is developing analytical models to assess in-well groundwater flow conditions during the collection of groundwater samples from wells being pumped. This information can be used to inform groundwater samplers on when and how to collect samples that are most reflective of the targeted aquifer or...
