A field assessment was performed to measure the emissions of volatile organics from a petroleum refinery landtreatment site. As part of the study, the emissions of total volatile organics from surface-applied and subsurface-injected oily sludge were measured over a five week period. The effect of soil tilling on the emissions was also monitored. Volatile organic emission rates were measured using the emission isolation flux chamber method. Soil samples were collected during the test periods for determination of soil properties and oil levels. Soil surface and ambient temperatures inside the flux chambers were also measured throughout the test periods to determine their influence on emission rates.
