FENV’s remediation engineers and scientists work together to design the most cost-effective remedial design and remediation technologies that will take our clients to regulatory closure and/or through the legal process.

​

Remedial Design

The selection of the most effective remedial design is critical to the success of the project. FENV offers analyses and feasibility studies of various remedial actions and their effectiveness on the remediation of all manner of contaminants and media. Our professional engineers, geologists, hydrogeologists, soil scientists and other professionals leverage their expertise in selecting the technology (or multiple technologies) which will be the most effective for each site’s unique characteristics and the future use of the site.

​
