Applicant's summary and conclusion

Conclusions:
The percent distribution was 81.4% to soil, 18.3% to water, 0.19% to sediment, and 0.05% to air.
Executive summary:

Distribution was calculated according to Mackay, Level III, using equal emissions to air, water, and soil. The percent distribution was 81.4% to soil, 18.3% to water, 0.19% to sediment, and 0.05% to air.
