Model compounds have been selected for research on geochemical and biochemical processes controlling movement and attenuation of organic chemicals in the subsurface environment. The compounds represent chemical classes that are of concern to human health or may degrade water quality, that are environmentally mobile or persistent, and that are present in wastes or anticipated in the future from a number of emerging energy technologies. At present, the model compounds selected for the subsurface program represent a preliminary set of experimental materials that may evolve as the need arises. The selection is designed to guide rather than restrict research and to facilitate integrate basis scientific investigations of processes controlling subsurface movement, attenuation, and transformation of organic compounds and mixtures. Other compounds that differ from the model compounds in structural properties may be included to test new hypotheses on important subsurface physicochemical and microbiologic reactions affecting transport. New compound classes may also be added as information develops on the organic composition of energy and defense wastes. The compound classes differ in structural properties and chemical functionality and will be used to probe important mechanisms involved in adsorption/desorption and degradation. By using compounds within classes that systematically span ring number and solubility, the research will bracket the subsurface behavior of the class and, thus, allow for comparisons between chemical classes of different functionality. 56 references, 7 figures.
