The isotherm model equations are: Linear: S = KdC Linear with So > 0: S = KdC + So Freundlich: S = KfC'm where S is the constituent concentration on soil (ug/g), Kd is the linear sorption coefficient (ml/g), C is the constituent concentration in water (ug/1), So is the soil concentration at C = 0, n is the unitless Freundlich exponent, and Kf is the Freundlich constant (I'/nug('-'/n)/g). The parameters Kd, So, Kf, and n are estimated using linear regressions on the sorption data. The parameter So represents that portion of constituent concentration on the soil that is sorbed irreversibly. 2 Results Results are provided in Tables 1 through 8 by constituent and sample. The results include parameter estimates and indicators of the goodness -of -fit of the resulting model equations to the sorption data. 3 Comments and Recommendations In addition to the general comments and qualifiers offered in the Results and Table 16 of the original report, the following comments and recommendations are provided. For the fate and transport model, the range of sorption estimates (maximum and minimum) should be used as the upper and lower limits for selecting a calibrated value that is consistent with measured constituents. For a specific constituent and sample, the isotherm model with the minimum chi-square value best represents the lab data in its arithmetic form. Linear isotherms with So < 0 are considered not applicable because they imply negative soil concentrations (S) as constituent concentration (C) approaches zero. For linear isotherms with So > 0, the y-intercept So is assumed to represent irreversible sorption as opposed to previous exposure to the constituent in the field which is manifested as a negative -sloping or irregular isotherm as would have been noted in the original report. Freundlich isotherms with n < 1 are considered not applicable because they are not concave downward (Freundlich 1924). For constituents not considered for Marshall, sorption values may be transferable from other sites with similar geochemical settings, or may be estimated using site -specific data from the Comprehensive Site Assessment in a geochemical model. 2 4 References Freundlich H. 1924.
