Ex Situ Chlorinated Solvents AOTech
ORIN successfully treated BTEX contaminated groundwater utilizing in-situ chemical oxidation. Previous vacuum extraction events were unsuccessful in achieving full clean-up of the contamination. The client elected to implement DPT injection to completely destroy the site COC. Sodium persulfate catalyzed with sodium hydroxide effectively oxidized contaminants within the matrix. In addition, a vacuum truck was utilized during chemical injection to remove highly contaminated groundwater and to provide hydraulic control. Thirty-nine injection points received a combined total of 3,510 gallons of treatment chemistry.
