Terramend® Reagent was used to remediate approximately 10,500 cubic yards of soil impacted by diesel petroleum hydrocarbon at levels ranging from 500 mg/kg to 3,000 mg/kg.
Terramend® reagent was applied to excavated TPH-impacted soil in a soil remediation cell. The remediation cell was irrigated to achieve the desired water holding capacity level to create optimal conditions for aerobic bioremediation of TPH compounds in soil.
TPH-d concentration was monitored biweekly using samples collected in 10 sections within the remediation cell. The remedial target of 400 mg/kg was achieved in all sampled sections after 120 days of remedial activity.
