SOIL OXIDANT BLENDING-RCRA/VRP SITE -
(OKEFENOKEE SWAMP) MANOR, GA
Contaminants:
Paint Solvents/
VOCs (toluene,
naphthalene)
Treatment:
Soil Blending-CHP/Persulfate
Site Status:
NFA
-
The site is located near the Okefenokee Swamp in the Coastal Plain geologic province. Extensive subsurface investigations indicated the presence of creosote NAPL, PAHs, and pentachlorophenolassociatedwithpastdischargesinasurfaceimpoundment. Contamination was observed in shallow and intermediate depth ground water zones to depths of 55-65 where a clay aquitard was encountered. Based on an evaluation of remedial options, a strategy was devised using soil oxidant blending in the source area coupled with an Oxidant-Bio based PRB or phyto remediation barrier for boundary control.
-
An initial soil blending pilot was performed in 2010 resulting in NAPL removal from CHP-permanganate oxidation. A follow-up blending pilot was performed in 2012 using a higher volume dose of CHP only. The results indicated significant reduction exceeding target goals (see graph below). Full scale treatment is pending based on a phased-in treatment approach.
