EMA conducts all phases of soil and groundwater remediation from initial AFSS investigation through remedial action selection, implementation, and project closure. EMA's approach which utilizes field analysis of contaminants to reduce costs and phases of investigation while better defining the contaminate source area. This technique has been used by EMA to fully define sizable contaminate plumes in as little as two days and has also proven highly compatible with the tiered evaluation approach of risk-based corrective action (RBCA).

When evaluating site remediation alternatives, EMA first considers the actual need for remediation. EMA has state of the art contaminate modeling capabilities to assess and support natural attenuation proposals as well as RBCA Tier 3 -type evaluations. If the level of contamination relative to applicable regulations warrants active site remediation, EMA will design a remediation system based on the contaminants of concern, the subsurface conditions, the distribution of contaminates, and the phases of contamination in the subsurface.
