  • 500,000+ gallons of water collected and treated
  • Work conducted adjacent of residential houses.
  • Site Restored to Pre-Remediation Conditions

SES undertook a project involving the excavation and segregation of over 17,000 tons of non-hazardous soils from a former petroleum bulk storage facility near the Oneida River and residential properties. This endeavor faced considerable challenges due to its location and excessive seasonal rainfall.

The remedial efforts included soil excavation, with depths reaching 10 feet below grade. Managing impacted groundwater, especially below the groundwater table, and surface water due to the site’s seasonal wetland status was essential.

The groundwater treatment process utilized a weir tank for flow regulation and initial filtration, followed by 25 and 10-micron bag filters to remove larger impurities. Finally, 2000 pounds of granular activated carbon effectively adsorbed petroleum-related compounds, ensuring safe water for various purposes.

Odor suppression equipment was deployed to address nuisance odors and vapors from excavated petroleum products.

Following soil removal, nonhazardous material was transported to an approved local landfill. On-site soils not requiring off-site disposal were repositioned below a 2-foot soil cap. During the project, the existing drainage swale was bypassed to facilitate excavation through the waterway.

Over 17,800 tons of imported material were used to backfill the site, placed in one-foot lifts. Site restoration involved importing and placing 1,500 tons of wetland topsoil, 1,000 tons of non-wetland topsoil, drainage piping, leaching fields, and plantings, including wetland trees and shrubs, to restore the area.
