A gasoline underground storage tank pit was contaminated with dissolved gasoline analytes following removal and backfill of a 10,000 gal UST that prevented closure of the site.
Sixteen (16) biosparge points were driven into groundwater through a pea gravel/colloidal clay matrix. Remtech’s native bioremediation accelerator HC-2000 was injected on a weekly basis topically and
through the sparge tips. A compact air and HC-2000 injection system was used to pulse air and enzyme into the tank pit.
At the end of a six (6) week treatment period, heterotrophic plate counts jumped to several million CFU/ml. Groundwater BETX analytes were reduced - 98% for benzene, 96% for
ethylbenzene, 99% for toluene, and 94% for total xylenes.
The tank pit was closed that prevented additional treatment and minimized additional facility operational interruptions.
