Passive Diffusion Bag Samplers and No Purge Groundwater Sampling

 · Posted on September 25th, 2018. For over a decade or more passive diffusion bag samplers (PDBS) have increasingly become a technique for a no purge sampling approach. PDBS are semi-permeable low-density poly-ethylene bags filled with clean distilled deionized (DI) water which can allow Volatile Organic Compounds (VOCs) to diffuse across the bag.
