Using passive-diffusion bag (PDB) samplers as a ground-water monitoring technique has become more popular in recent years as various laboratory and field studies have shown acceptable data-quality objectives (DQOs) can be achieved through their use. The PDB sampler is deployed in an aqueous environment (e.g., well or borehole), where passive diffusion through the semi-permeable membrane of the sampler enables the water quality in the sampler, which is typically filled with deionized water, to equilibrate with that in the surrounding aqueous environment (Harter and Talozi, 2004). The type of membrane determines which solutes are able to pass into the...
