Klozur® CR Used to Remediate Benzene, Toluene, Ethylbenzene, Xylene and MTBE at active UST Site

An in situ chemical oxidation treatment using Klozur® CR was completed to reduce contaminants caused by a petroleum release at a marina in the Savannah, Georgia area.

Type of Site

Active underground storage tank site located at a marina


Exo Tech, Inc.


Ft. McAllister Marina, near Savannah, Georgia

Contaminants Treated

Benzene, Toluene, Ethylbenzene, Xylenes, MTBE


The location of the site required site treatment at or near In-Stream Water Quality Standards (ISWQS). Klozur® CR was selected to treat the impacted groundwater in order to meet the stringent goals.  Prior to injection, BTEX was detected in excess of 44,000 μg/L, with benzene detected as high as 3,280 μg/L.


Post injection results showed significant reduction in dissolved benzene/total BTEX. A No Further Action was received from the Georgia EPD in November 2010, with site closure achieved after only one injection.
