ExposMeter - Model EGV -Volatile Organic Compounds (VOC) Groundwater Sampler

EGV provides a cost-saving alternative to conventional sampling methodologies, eliminating well purging and decreasing field labor costs. They provide depth-specific, time-weighted samples of dissolved phase VOCs. EGV is based on PDB (Polyethylene Diffusion Bag) technology developed by Don Vroblecky of USGS and Thomas Hyde of General Electrical.
