The research deals with the validation of the flux chamber method for measuring volatile organic emissions from liquid surfaces in treatment, storage and disposal facilities (TSDF). A simulated surface impoundment was constructed so that method precision and accuracy could be determined under controlled conditions. Operational parameters studied included sweep flow rate, sampling time, sweep flow position and chamber depth in the liquid. Environmental factors included wind velocity, solar intensity, emission rate, and chemical composition. Field testing was performed at two TSDFs, a wastewater treatment facility at a chemical plant, and a waste stabilization facility. The results showed that good precision can be obtained under a variety of conditions, but that the method suffers from a negative bias that varies with the compound under analysis.
