Common Misconceptions
EAS™ Common Misconceptions
1. Biodegradation requires aerobic conditions
Anaerobic degradation is the predominant mechanism for natural attenuation at most sites.
2. This is in situ oxidation (Persulfate Radical)
EAS™ process is bio-enhancement.
3. Anaerobic Biodegradation is too slow
Significant contaminant reduction occurs in as little as 3 months.
4. Hydrogen Sulfide gas will be generated
Our clients report that they have never detected this, but they continue to monitor.
5. Addition of sulfate solution will result in increased plume migration
The volume of sulfate solution is minimal in comparison to the volume of the aquifer being treated.
6. This technology will result in a lingering sulfate contaminant plume
Sulfates are rapidly utilized after application.
