Low-Flow Purging Reduces Management of Contaminated Groundwater
Purging a monitoring well prior to sampling removes stagnant water in the well casing and ensures collection of groundwater samples representative of formation water. Traditionally, a number of well casing volumes are removed (from three to five) and water stabilization parameters are monitored during removal of the casing volumes. Temperature, pH and specific conductance are routinely monitored ...

A new no-purge, non-displacement groundwater sampler
What Is It? The HydraSleeve sampler is designed to collect representative water samples from monitoring wells without purging. The disposable sampler collects a discreet sample from only the 'fresh formation' water in the screened interval of the well. It is fast, inexpensive, simple to use, generates no purge water and collects a sample suitable for all analytical parameters. Why It Works The ...

Groundwater: Low-flow Purging and Sampling
Significant timesavings, improved sample process integrity, quality assurance and minimal quantities of potentially contaminated purge water to manage - are attractive as the focus on groundwater quality sharpens and economics demand best cost-benefit based methods Water has become a vitally important resource. Maintaining its quality and quantity and avoiding pollution are set to be watched ...
