A surface- and a ground-water matrix were spiked with 87 volatile organic compounds (VOCs) to achieve a theoretical concentration of 0.5 microgram per liter for most VOCs. Five replicate spike samples from each water matrix were stored and analyzed at selected time intervals up to 216 days. To assess daily analytical variability, three replicate continuing calibration verification standards were analyzed at the same times as the spiked water matrices. The results of this study provide information about the stability of low concentrations of VOCs in water samples preserved with hydrochloric acid, chilled at 4 degrees Celsius, and kept in the dark prior to analysis. This report describes the study design and presents the results of samples analyzed on day 0, 14, 28, 37, 47, 56, 112, 156, and 216.
