"From the Introduction: " The purpose of this guide is to aid in determining whether a particular volatilization technology can successfully remove organic contaminants from water. It describes the performance evaluation of common volatilization technologies and provides an approach for selecting the appropriate technology for a given situation. Data necessary for the evaluation are described and, whenever possible, background data are given for selected hazardous organics. In addition to being useful for equipment selection, it can be used as an educational tool for background data on volatilization technologies or as a decision-making tool for purchasing a mobile technology. The impetus for developing a guide stems from involvement of the Hazardous Waste Engineering Researching Laboratory's Releases Control Branch in technical assistance activities that require assessment of the feasibility and cost of various treatment options. It was recognized that EPA On-Scene Coordinators (OSC) and their technical support personnel are often faced with changing or uncertain conditions that could affect the cost and feasibility of removing volatile substances from water. As conditions change or as some of the uncertainties are resolved, the OSC's technical support personnel are called upon to revise their estimates accordingly. It was recognized that the OSC and their technical support staffs did not have a concise guide on the subject of volatilization technologies and their application to spill cleanup operations. People with some technical training in chemistry and thermodynamics, but limited experience in participating or coordinating cleanup activities at uncontrolled hazardouswaste sites will find the guide useful.

The transfer across the surface of environmental waters is of interest as an important phase in the geophysical and natural biochemical cycles of numer ous substances; indeed it governs the transition, one way or the other, be tween the dissolved state in the water and the gaseous state in the atmo sphere. Especially with increasing population and industrialization, gas transfer at water surfaces has become a critical factor in the understanding of the various pathways of wastes in the environment and of their engineering management. This interfacial mass transfer is, by its very nature, highly complex. The air and the water are usually in turbulent motion, and the interface be tween them is irregular, and disturbed by waves, sometimes accompanied by breaking, spray and bubble formation. Thus the transfer involves a wide variety of physical phenomena occurring over a wide range of scales. As a consequence, scientists and engineers from diverse disciplines and problem areas, have approached the problem, often with greatly differing analytical and experimental techniques and methodologies.
