Investigation / Remediation / Closure

SESCO’s team of professional geologists, engineers and project managers have decades of combined experience in managing site investigation and remediation projects regulated by various state and federal agencies. Our team has extensive experience working towards closure for sites regulated under the Indiana Department of Environmental Management (IDEM) programs, such as Leaking Underground Storage Tanks (LUST), Excess Liability Trust Fund (ELTF), State Cleanup, the Indiana Brownfields Program, and the Voluntary Remediation Program (VRP). We are also experienced with processes and regulations for sites within the U.S. EPA programs, such as Region 5 CERCLA and other programs within the Superfund Division. At SESCO, we design innovative investigation strategies focused on risk based approaches to reach expedient site closure and meet client goals. Should the investigation lead to the need for remediation, our staff will design and implement a corrective action plan that is cost effective and adheres to state and federal guidelines and regulations.
