Strategic Value Proposition

The current Work Plan represents a critical lifecycle pivot for the American Thermostat asset. Site management is transitioning from passive containment to active source isolation.

Institutional Logic: RI/FS

The Remedial Investigation (RI) phase serves as technical due diligence to quantify subsurface liability. The Feasibility Study (FS) acts as the optimization model to select the most capital-efficient exit strategy.

Operational Scope

Phase 01 / Source Forensics

Deep-Horizon DNAPL Isolation

Targeted drilling and vertical profiling focus on locating DNAPL. Advanced hydrogeological modeling is deployed to delineate high-density contamination zones.

Deep drilling is used to find and map the exact "pockets" of heavy chemicals trapped underground so they can be stopped at the source.

Phase 02 / Receptor De-Risking

Waterline Infrastructure Integration

Deployment of a 3.5-mile municipal waterline extension removes the exposure pathway for residential receptors, providing a permanent risk-transfer solution.

This replaces the neighborhood's reliance on well water with a new, safe public water system to ensure residents never come into contact with pollutants.
