The site consists of a layer of saprolite and weather material overlying fractured rock.
Targeted Environmental Media:
 Fractured Bedrock
Major Contaminants and Maximum Concentrations:
- Dioxane (40,000 µg/L)
No technologies selected.
- Other (Accelerated Remediation Technologies, LLC (ART), uses in-well technology combining in situ air stripping, air)
Comments:
The site was used to compare the Accelerated Remediation Technologies (ART) In-Well Technology to a multi-point soil vapor extraction/air sparging system.
Not identified in the reference.
The concentration of 1,4-Dioxane was reduced by up to 90 percent within 90 days. Compared to the removal rate of multi-point soil vapor extraction/air sparging system, the removal rate of the ART well was 80 times greater. Full-scale implementation on the site confirmed the effectiveness of the ART in treating 1,4-Dioxane.
