Select VOCs in ambient air were measured at fenceline locations using modified EPA Method 325 A/B with passive tubes and EPA Compendium Method TO-15 with canister samplers. One-week, time-integrated samplers were deployed for eight weeks with tubes and canister samplers deployed in duplicate. Good precision was obtained from the duplicate tubes (<7%) and duplicate canisters (≤10%) for BTEX, PCE, and styrene. The tubes yielded statistically significantly higher concentrations than canisters for BTEX and lower levels for styrene, although all differences were estimated to be <0.1 ppbv. No concentration differences among the four Whiting sites were found for any of the VOCs.
