Remedial Investigation & Feasibility Studies

Our practice at complex sites often follows the remedial investigation and feasibility study process established by federal and state guidelines.

This RI/FS work requires multiple phases of investigation, risk assessment, calculation and negotiation of cleanup goals, and remedial technology screening and evaluation.

Successful RI/FS project development also normally requires direct interaction and negotiation with regulatory agencies. EES is effective in this setting, and we have built cooperative and respectful working relationships among regulatory managers and decision-makers in Oregon and Washington.

Our RI/FS experience includes evaluating sites impacted by chlorinated solvents, fuels and other hydrocarbons, PCBs, wood treating chemicals and derivatives, metals, agricultural chemicals, acids and bases, and other regulated substances.
