Site Characterization
Environmental site characterization, or investigation, is one of the most important steps in any cleanup program. If not well designed and executed, environmental investigations can be prolonged and cost as much as the remedy. Poor or improper site characterization can lead to unnecessary remediation, selection of an inappropriate or poorly performing remedy, or the presence of unidentified sources of contamination or exposure pathways which must be addressed after the rest of the site is considered clean. Much of our environmental investigation experience is centered around the RCRA Facility Investigations (RFI) under the RCRA Corrective Action program. Our RCRA Corrective Action experience in Ohio and the midwest is unmatched.
