Graph of PCB Concentrations for BX-6 Fill (Construction)

Notes:

And this is again a similar plot for PCB's showing the changes that were predicted. There are changes where the dredging activities are occurring both in the borrow pit area and off the runways, and we see some increases here in the yellow at both areas. The location of maximum change again is showed in these frequency plots where the existing environment exceeds the water quality objective that we see, about a factor of five-fold increase at the center of the plume for PCB's for the construction scenario.
