Site Remediation

  • Soil Excavation & Disposal
  • Remedial Treatments & Systems
  • Monitored Natural Attenuation

Once a determination is made that a site requires remediation, SAGE evaluates alternatives and determines the best and lowest cost cleanup method. The remediation process includes risk analysis; the identification of corrective action goals, objectives, and permit requirements; and design and implementation of the selected corrective action.

If feasible, the excavation and removal of contaminated soil is usually the quickest and lowest cost remedial option. We have performed large soil remediation projects involving the excavation and off-site disposal of soil contaminated with petroleum hydrocarbons, chlorinated solvents, pesticides, coal tar and heavy metals. Where applicable, we reduce costs through recycling (e.g., incorporating oil-contaminated soil as asphalt feed stock) or other innovative disposal options.

Our staff also has experience with remedial technologies designed to treat soil or groundwater impacted by various types of contamination. SAGE’s in-situ remediation projects have included soil vapor extraction (SVE), high vacuum extraction (HVE), air sparging, and chemical oxidation treatment systems.

Once the contamination source has been removed, monitored natural attenuation (MNA), which relies on natural processes to reduce contaminant concentrations, may be an option. SAGE has prepared MNA plans and reports including the statistical evaluation of monitoring data to gauge progress toward remedial goals.
