Remedial Design and Action

3E staff have provided site remediation services from investigation and characterization to design and construction oversight for over 20 years. Our investigation approach focuses on collecting all the site characterization data necessary to adequately design and implement a presumptive remedy and create and "exit strategy". Our experience indicates a proactive and aggressive approach with regulators and other stakeholders and collecting as much screening-level data as possible resulting in a fast-track schedule and cost savings to our clients.
