The Waste Isolation Pilot Plant (WIPP) site is designed to demonstrate safe disposal of transuranic (TRU) mixed waste. An air monitoring program has been established at the WIPP site to verify that volatile organic compounds (VOCs) do not migrate out of the disposal unit. In this air monitoring program, modified commercially available dual canister samplers are used to collect air samples for VOC analysis. Sampler certification, sample collection, and sample analysis are performed based on the procedures contained in US Environmental Protection Agency`s Compendium Method TO-14. The canister samplers are certified for cleanliness by passing humid zero air through the entire sampling system and collecting a sample in a canister over a 24-hour period. In addition, each canister sampler is certified for target compound recovery efficiency by passing a humid calibration gas standard through the entire sampling system and collecting a sample in a canister over a 24-hour period. In this paper, the authors discuss the techniques developed for meeting the stringent certification requirements of the monitoring program and present data to support the need for these stringent requirements.
