This two-volume report describes the conceptualization, measurement, and use of the partition (or distribution) coefficient, K(sub d), parameter, and the geochemical aqueous solution and sorbent properties that are most important in controlling adsorption/retardation behavior of selected contaminants. The report is provided for technical staff from EPA and other organizations who are responsible for prioritizing site remediation and waste management decisions. Volume I discusses the technical issues associated with the measurement of K(sub d) values and its use in formulating the retardation factor, R(sub f). The K(sub d) concept and methods for measurement of K(sub d) values are discussed in detail in Volume I. Particular attention is directed at providing an understanding of: (1) the use of K(sub d) values in formulating R(sub f), (2) the difference between the original thermodynamic K(sub d) parameter derived from ion-exchange literature and its 'empiricized' use in contaminant transport codes, and (3) the explicit and implicit assumptions underlying the use of the K(sub d) parameter in contaminant transport codes. A conceptual overview of chemical reaction models and their use in addressing technical defensibility issues associated with data from K(sub d) studies is presented. The capabilities of EPA's geochemical reaction model MINTEQA2 and its different conceptual adsorption models are also reviewed. Volume II provides a 'thumb-nail sketch' of the key geochemical processes affecting the sorption of selected inorganic contaminants, and a summary of K(sub d) values given in the literature for these contaminants under oxidizing conditions. The contaminants chosen for the first phase of this project include chromium, cadmium, cesium, lead, plutonium, radon, strontium, thorium, tritium (3 H), and uranium. Important aqueous speciation, (co)precipitation/dissolution, and adsorption reactions are discussed for each contaminant. References to related key experimental and review articles for further reading are also listed.
