Interstate Technology and Regulatory Council (ITRC) Diffusion Sampler Information Center
This Interstate Technology and Regulatory Council (ITRC) Workgroup training summarizes major points of the US Geological Survey document User's Guide for Polyethylene-Based Passive Diffusion Bag Samplers to Obtain Volatile Organic Compound Concentrations in Wells (Vroblesky, D.A., 2001: Part 1 (3.5Mb); Part 2 (5.4Mb)), developed in cooperation with ITRC's Diffusion Sampler Team, and discusses the technical and regulatory considerations associated with deployment of PDB samplers. Also available is the Diffusion Sampler Team's newest guidance document titled "Technical and Regulatory Guidance for Using Polyethylene Diffusion Bag Samplers to Monitor Volatile Organic Compounds in Groundwater", available for download from the ITRC web page
