Background
This addendum provides three sorption isotherm equations for batch data analyzed and initially
reported in the Soil Sorption Evaluation for Buck Steam Station (Langley and Oza 2015). 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 Buck, 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.
