CASE STUDIES

Redox Tech-,-L-L.

A CASE STUDY FOR IRE APPLICATION OF ANEAROBIC BIOCHEM PLUS
(ABC) TO TREAT GROUNDWATER CONTAMINATED WITH
1,1,1-TRICHLOROETHANE (TCA) AND DAUGHTER PRODUCTS
In April 2006, a pilot test was conducted involving injection of Anaerobic Biochem Plus
(ABC) at a site in Greenville, OIL, where elevated concentrations of TCA and daughter
products DCA and CA have been reported in groundwater: The source of the contamination is
believed to be from a disposal pit and two former burn pits, which were excavated as part of
remedial efforts between 1989 and' 1995. To date, ongoing remedial efforts have included
groundwater recover,treatment, and discharge to the local publicly owned treatment works. A
groundwater treatability study conducted in 2005 determined that due to the presence of
daughter products, reductive dechlorination has occurred at the site. However, the lack of
organic carbon and sulfide indicates that the reducing environment has insufficient substrate to
promote full dechlorination. ABC+ was selected as a cost effective means to stimulate
enhanced reductive dechlorination (ERD) and promote in situ treatment of the target
contaminants.
Anaerobic Biochem Plus (ABC+) is a mixture of Anaerobic Biochem (ABC®) and 10 per cent
by weight of Zero Valent Iron (ZVI). ABC® is a patented mixture of lactates and fatty acids.
ABC® contains soluble lactic acid as well as slow- and long-term releasing compounds.
Treatment of chlorinated organic compounds by ZVI has been proven and widely accepted as
an effective in situ remediation technology of chlorinated solvents such as TCA. The addition
of-ZVI-to—the ABC® -mixture provides a numberofadvantages-for -enhanced-reductive
dechlorination (ERD). The ZVI will provide an immediate reduction. The ABC® will provide
short-term and long-term nutrients to anaerobic growth, which also assists to create a reducing
environment. In addition, the corrosion of iron metal yields ferrous iron and hydrogen, both of
which are possible reducing agents.
Injection of the ABC' was performed using Geoprobe direct push drilling techniques and
targeted two separate geologic units. One unit was a silty clay aquitard from approximately 10
to 20 feet bgs. The other unit was a confined sand and gravel aquifer from 20 to 35 feet bgs.
The aquitard was addressed near monitoring well MW-17B and the aquifer was addressed near
monitoring well MW-14C (Figure 1). Two separate areas were selected so that injection
within one unit would not influence the other. Two injection locations were addressed within
each test area.
The ABC+ was mixed on site and injected directly into the subsurface through the Geoprobe
drill rods. 600 and 900 lbs of the ABC® formula were injected into the aquitard and aquifer
units, respectively. The ABC® was mixed with water at a 15 percent by weight solution to
increase dispersion, resulting in approximately 400 and 600 gallons for the aquitard and aquifer
units, respectively. ZVI was added to the ABC® formula at a 10 per cent by weight ratio.

Injections were conducted at increments of 4 feet across the target zone(s) to ensure adequate
vertical dispersion occurred.
Groundwater samples from monitoring wells were collected monthly after the injections were
completed. During this time the groundwater recovery system remained off. Figure 2 presents
graphical representation of the results from monitoring wells MW-17B and MW-14C.
Groundwater concentrations of TCA were observed to decrease in both the aquifer and aquitard
units after injection of ABC+. Within 6 months, concentrations in both units had dropped over
99% from pre -injection values to below the action level of 200ug/L. The reduction of TCA
resulted in the corresponding production of daughter products DCA and CA and therefore
increases in these concentrations are observed. However, 7 months after the injections were
completed, DCA concentrations within both zones have begun to decrease. In fact,
concentrations of DCA within the aquitard (MW-17B) have dropped below the action level of
1,400 ug/L.
Based on•results from this pilot study, full-scale implementation of ABC+ within the aquifer is
planned for Spring 2007.
