SES Completes Maider Road Remediation Project
This project consisted of SES excavating and segregating over 17,000 tons of non-hazardous soils from a former petroleum bulk storage facility located adjacent to the Oneida River and residential properties. This project presented significant challenges due to the location and excessive seasonal rain throughout the course of the excavation.
The remedial activities included soil excavation, with some areas as deep as 10-ft below grade. Management of impacted groundwater was required as the deep excavation proceeded below the groundwater table; as well as management of surface water due to the site being a seasonal wetland. Odor suppression equipment was also needed to subdue nuisance odors and vapors from the petroleum products brought up by the excavation. Following the removal of the soils, the nonhazardous material was sent to an approved local landfill, and all soils that did not require off-site disposal were relocated on-site and placed below a 2-foot soil cap.
During the project, the existing drainage swale was bypassed to allow for the excavation through the waterway. The site was backfilled with over 14,800 tons of imported material placed in one-foot lifts.
Finally, site restoration activities were done including the import and placement of 1500 tons of wetland topsoil and 1,000 tons of non-wetland topsoil, drainage piping, leaching fields, wetland, and non-wetland plantings including wetland trees and shrubs.
