Figure 3.1 Duke Forest gate 11
waste site in North Carolina: (a)
modeled paradioxane plume after
50 years of natural attenuation;
(b) paradioxane plume modeled
after 10 years of pump and
recharge remediation. Numbered
points are monitoring wells. The
difference in plume size from
intervention versus natural
attenuation is an example of the
complexity of risk management
decisions; that is, does the
smaller predicted plume justify
added costs, possible risk
trade-offs from pumping (e.g., air
pollution), and disturbances to
soil and vegetation?
