| This report was produced by the Interstate Technology and Regulatory Council (ITRC). This guidance contains protocols for five passive sampling technologies. Passive sampling is synonymous with no-purge sampling. The technologies included in this document include Snap SamplerTM and HydrasleeveTM (grab-type well water samplers); regenerated-cellulose dialysis membrane sampler and rigid, porous polyethylene sampler (diffusion/equilibrium-type samplers), and GORETM Module (a diffusion and sorption-type sampler). The intent of the current document is to provide a sound guidance on how to properly deploy and collect samples using passive devices. |
