Soil and Groundwater Remediation
GRI offers high vacuum/high volume soil vapor extraction and dual-phase extraction systems. We provide and operate these mobile systems using various sites air board permits. If local discharge permits for treated water can be obtained, immediate setup, startup, and site remediation activities can be implemented on the same day the permit takes effect.
The systems are designed to quickly remove volatile contaminants, such as petroleum hydrocarbons, and other volatile organic compounds. In addition, we have in-house equipment to provide pump and treat, sparging, and subsurface injection of oxidation products.
