Site Remediation Services

Excel offers turn-key site remediation services, including expert evaluation of feasible remedial action alternatives, engineering design of remediation systems, implementation of large and small-scale soil and groundwater remedial action projects, construction management, operation and maintenance, post-remediation monitoring and reporting services.

We provide comprehensive remediation consulting services, from evaluation of feasible remedial action alternatives and preparation of effective remedial action work plans to design and implementation of innovative soil and groundwater remediation systems, including remedial action alternatives that are fully integrated into redevelopment plans.

We prepare technically sound bid packages for competitive selection of qualified remediation contractors, air and discharge to surface water or groundwater discharge permitting services, system installation and contractor supervision during remedial action implementation, remedial action system operation and maintenance.  The following is a more detailed discussion of our capabilities:

Our professionals are experienced in the evaluation and ranking of feasible remedial action alternatives and technologies, including “no-action” and Natural Remediation alternatives, the use of in-situ and ex-situ treatment technologies, and the integration of engineering and institutional controls in lieu of active remediation. We bring hands-on experience and in-depth technical knowledge with implementation of a wide range of remedial action techniques to the remedial action alternative evaluation and selection process.

We work extensively with the implementation of innovative soil and groundwater treatment technologies and focus on ways to integrate technical approaches to maximize results and cost-savings. We have successfully designed and implemented remediation systems to recover free-phase fuel oil as well as to treat soil and groundwater contaminated with petroleum products, including gasoline, No. 2, 4, and 6 fuel oil, solvents and chlorinated organics, chemicals such as pentachlorophenol and dibenzofurans, and a wide variety of heavy metals.

We have coordinated all aspects of Pilot Tests, Interim RA programs, and full-scale RA plans with General Contractor, lead engineer, and lead environmental consultant responsibilities.

Our professionals have been successfully integrating Engineering Controls, Deed Notices, and CEAs into remedial action plans since the inception of these NJDEP “administrative tools” and we have first-hand experience with the NJDEP under a wide variety of circumstances, including precedent-setting situations where NJDEP approval was obtained where it had never been approved by the Department before.
