The Hidden Multipliers
At Cape Cod defaults (Kd=1.5, K=95), P&T wins at the 100-year horizon by roughly $22M ($77M vs $99M for PRB). Drag Kd below 0.5 — sandy aquifer, weak sorption — and the gap widens because P&T cleanup is faster. Now try the MCL buttons: drop from 4 ppt to 1 ppt and watch cleanup times nearly double. That regulatory uncertainty dwarfs the geological uncertainty.
This tool uses the Domenico analytical screening model (Model A from the study). It gives you the right intuition about parameter sensitivity, but it assumes a homogeneous aquifer. Our full Monte Carlo analysis shows that when you add heterogeneity and parameter uncertainty, P&T contains the plume in 100% of realizations at $32M flat NPV — while PRB runs $81-99M. The screening intuition pointed the wrong way; the Monte Carlo settled it.
