Conclusions
•Inflow, major source of contamination. Better place for remediation to occur.
•Between Sites 2 and 3, there is also some unaccounted flux of Fe and Zn. Possibly due to ground water inflow.
•Between Sites 1 and 2, there is a high loading of Fe. Possibly due to ground water inflow.
•If Sites 1-4 cleaned up, about 70% of Fe and 40% of Zn loading could be dealt with.
