EWMI’s remediation expertise makes us a leader in the environmental management field. In 2019, a landfill requiring expansion selected EWMI to complete the job thanks to our extensive experience in remediation across the nation.

Read on to learn more about EWMI’s remediation approach and how our team prepares for success, handles challenges on the job site and communicates openly with stakeholders during projects.

EWMI’s Remediation Challenge: Hazardous and Non-Hazardous Soil Mixtures

Before the landfill could be expanded, an excavation of hazardous K087 waste and non-hazardous soil was necessary. There was a mixture of soil and hazardous waste, which could be visually delineated from the soil.

Prior to beginning the remediation, the EWMI remediation team pre-characterized the site, gridding out the excavation area and taking over 100 GeoProbe samples, which were sent to disposal facilities for testing and approval.

This preparation allowed the EWMI Remediation team to plan how the site would be delineated and allowed adherence to a strict schedule while avoiding downtime once heavy equipment was mobilized.

EWMI’s Service-Oriented Solution

The samples were approved by an international facility, one of the only facilities in North America that could handle the high volume of hazardous waste. EWMI had already worked with the highly-vetted facility in previous projects, which streamlined the approval process.

EWMI’s Remediation team managed every aspect of the approval and transportation process, managing the import / export permits, customs invoices for material tracking, manifests, paperwork and weight tickets – simplifying the project for the customer while utilizing the best-matched disposal facility for the waste.

The EWMI Remediation team faced a significant challenge as the excavation progressed. The engineer’s figures had estimated that about 7,000 tons of hazardous waste needed to be removed, transported and disposed of. Once the EWMI Remediation team began digging, they discovered that 18,000 tons of hazardous waste needed to be removed from the site, with little flexibility to the schedule, and accepted by the same international facility.

Close, clear communication between the EWMI Remediation team, site owner, design engineer and QA/QC team allowed EWMI to accurately forecast the necessary changes.

The project was successfully completed in 2019, allowing the landfill to expand safely.
