Demonstration of the AGI Universal Samplers (F.K.A. the GORE (registered trademark) Modules) for Passive Sampling of Groundwater
Abstract
The GORE Module is a passive sampler that was developed to sample air and water for a variety of volatile and semi-volatile organic compounds (VOCs and SVOCs). Recently, Amplified Geochemical Imaging (AGI) LLC (Elkton, MD) has acquired this technology, and the sampler is now known as the AGI Universal Sampler. The objectives of this project were to determine, when sampling ground-water, if the GORE Modules can provide (1) technically defensible analyti-cal data for VOCs and SVOCs and (2) substantial cost savings when com-pared with the US Environmental Protection Agency s (US EPA) low-flow purging and sampling method. Sampling was conducted at two sites: the Southern Bush River section of Aberdeen Proving Ground (APG), MD, and the former Pease Air Force Base in Portsmouth, NH. Analytes included chlorinated VOCs and hydrocarbon VOCs and SVOCs. Additional Modules placed in some wells allowed us to examine concentration gradients in those wells with depth both before and after low-flow sampling.
