Exponent’s capabilities in developing, implementing and evaluating the performance of corrective actions focus on the mitigation, remediation and restoration of environmentally-impacted media. We provide these services in response to the requirements of the CERCLA, RCRA, the Clean Air Act (CAA), , and natural resource damage assessment (NRDA) under both CERCLA and the Oil Pollution Act (OPA), and state-equivalent statutes. Exponent’s team has extensive experience with in-situ and ex-situ biological and physical treatment processes and with remediation of organic and inorganic compounds in groundwater, surface water, soil, soil gas, and sediments.
Our scientists provide an objective evaluation of project risks and a sound technical basis for advising clients regarding cost-effective remedial solutions. We work to develop appropriate and effective alternatives that clients can use to drive business decisions in a manner that supports regulatory agency approval. Because Exponent has no financial interest in the selection of any particular corrective action technology, our experts are able to provide technically unbiased evaluations of alternative remedial solutions, costs, and implementation scenarios that meet regulatory, legal and businesses objectives.
