Prediction of chemical movement in ground water can be complex. Solute transport calculations need to reflect appropriate mathematical treatment of sorption and retardation by aquifer materials. The presence of cosolvents further complicates solute transport prediction. Results from a series of experiments both simple (small tubes) and complex (soil columns) suggest adequate predictability of solute sorption and attenuation in the presence of cosolvents. The results indicate that simple (small tube) short‐term tests under a variety of sorbent concentrations can be used to predict soil column solute transport if appropriate physical properties are accounted for (soil type, organic load, bulk density). The final results indicate that low levels of cosolvents showed significant reproducible sorption/ attenuation reductions but probably are ultimately not important to overall solute fate.
