Remediation Decision Tool
Adjust site conditions and planning assumptions. Watch the recommended remedy — and its cost — change in real time.
The Hidden Multipliers
At Cape Cod defaults (Kd=1.5, K=95), PRB wins at the 100-year horizon. But drag Kd below 0.5 — sandy aquifer, weak sorption — and P&T becomes competitive because 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, P&T tail scenarios blow past $120M at P95 — reversing the remedy recommendation in cases where this screening tool says P&T wins.
