Applicant's summary and conclusion

Conclusions:
The EPI Suite Level III fugacity model estimates that the study substance will partition largely into the sediment compartment (69%), followed by the soil compartment (29%), water compartment (1.9%) and air (0.05%), based on the calculated values from EPI Suite and SMILES input.

Level III fugacity model estimates that the study substance will partition largely mainly into the sediment and soil compartments with very little into water and the least into air.
Executive summary:

The EPA EpiSuite Level III fugacity model estimates that the study substance will partition largely mainly into the sediment and soil compartments with very little into water and the least into air.
