MEMORANDUM
To: Debra Watts, Supervisor, Permits & Compliance Branch
Through: Evan Kane, Hydrogeologist, UIC Program Manager
From: I ' i . Mark Pritzl, Hydrogeological Technician, UIC Program
Re: Southern States' injection well application for the injection of Oxygen into an air
sparging system to enhance aerobic biodegradation of petroleum hydrocarbon
dissolved in groundwater at this site.
• This site is located in the Charlotte Belt of the Piedmont Physiographic Province of North
Carolina. The site is underlain by clays, silts and sands that grade down to mainly silty sands
to a depth of 40 feet below land surface (bls). Partially weathered metavolcanic bedrock was
encountered at a depth of roughly 40 feet bls. Competent bedrock has not been encountered
at this site.
• Shallow groundwater movement is generally toward the south-east across the entire site.
Water levels collected in May 2003, show that depth to the water table ranges from 3 to 16
feet below land surface (bls). The consultant has calculated average groundwater seepage
velocity to be 10 feet/year, and this may be somewhat conservative. Monitor well water level
data collected on May 8, 2003, indicate that the upper surficial aquifer is recharging the
transition zone, where most lateral groundwater movement takes place.
• VOC contamination exists in the surficial aquifer, and petroleum released from the former
dispenser island is the likely cause of VOC groundwater contamination. The dissolved
contamination is consistent with a petroleum release, and the table behind this summary
shows what was reported in the last sampling event.
• The site contains a combination Air-Sparge (AS) and Soil -Vapor -Extraction (SVE) system
that has been in operation since 1999. In March 2002, this system was discontinued due to air
quality issues. The AS system was to deliver ambient air to groundwater for the enhancement
of aerobic biodegradation of dissolved petroleum contamination. The SVE system was to
remove volatiles from both the unsaturated zone and the AS system. The AS system consists
of fourteen AS wells, each constructed to a depth of 25 feet, with a two foot screen from 23-
25 feet bls. (see map behind summary) The applicant proposes to augment the AS system
with the injection of pure Oxygen, and states that the SVE system will not operate during the
entire injection process.
• The AS system will be enhanced with the injection of pure oxygen to generate more dissolved
oxygen in groundwater for naturally occurring aerobic bacteria to use. These bacteria will
break down the hydrocarbons to CO2 & H2O, and the consultant has calculated the amount of
oxygen (oxygen demand) needed for the bacteria to break down the estimated dissolved
hydrocarbon contamination.

A L,
• The injection of oxygen will be done manually from 02 cylinders, utilizing 13 cylinders for
each of the three proposed injection events. At the beginning of each event, the AS system
will be turned on and allowed to equilibrate. Then, the 02 cylinder will be attached to a
feeder pipe and the ball valve will be slowly opened. The oxygen will be injected at a rate of
8 cubic feet per minute (cfm), and at this rate each 251 cubic foot 02 cylinder will last roughly
0.5 hour. The AS blower will introduce ambient air at 160 cfm, and the injection of pure
oxygen at 8 cfm will give a total rate of 168 din. This initial injection event will increase the
oxygen content of the injected air from roughly 21% to 26% by volume. After the initial
injection event, the other two injection events will be conducted approximately two weeks
apart. A 5 ppm to 10 ppm DO concentration is the goal in the core wells, which will
indicate that the surficial aquifer has increased its DO level. If a 5 ppm to 10 ppm DO
concentration can be achieved, then injection events beyond the three proposed will be
conducted on a monthly basis.
• Prior to initiation of the AS system and the addition of oxygen, monitoring wells in the core of
the plume will be monitored for dissolved oxygen (DO)(MW-1, MW-4 and MW-5). DO will
be monitored in these three monitoring wells for the duration of the injection event. Once all
of the oxygen has been added to the air stream, the system will be remain operational for an
additional hour to purge the lines of any oxygen -augmented air. DO will be monitored in
these three monitor wells at approximately 12 hours, 36 hours and one week post -system
shutdown. Long term monitoring will continue semi-annually, as required by the approved
CAP.
• Some of the limiting factors for 02 injection at this site are; there is significant dissolved iron
(ferrous) in the heart of the plume, and this could scavenge the delivered oxygen, preventing
the bacteria from utilizing it, the radius of influence of the injected oxygen may be limited so
as to be ineffective, and finally, the plume itself may be too toxic for the bacteria to propagate,
especially at total VOCs with concentrations above 10,000 ug/L.
• At this time, I recommend that a permit be issued to Southern States for the introduction of
oxygen into the AS system for the enhancement of aerobic degradation of dissolved VOCs.

MRO Review of June 2003 UIC Permit Application for Southern States Cooperative, Inc.,
Salisbury, NC. Groundwater Incident #12547. By Andrew Pitn�r, August 13, 2003.
I am familiar with the site and have reviewed the permit application. I support the proposed
injection, but offer the following comments:
• The calculations for oxygen demand should be taken as a very rough first estimate of
the amount of required oxygen. The assumptions made in these calculations are likely
to have significant error associated with them (treating the contamination in MW-4 as
benzene, when most of the contaminant mass is actually xylenes and trimethylbenzene
isomers; and no "fudge factor" to account for inefficiency of the delivery system).
Despite those issues, it is not an unreasonable way to get a first guess at the amount of
oxygen required.
• The goal of 5 to 10 ppm DO in core wells is seems optimistic given historical DO levels
at the site during and after operation of the AS/SVE system without the any additional
oxygen input. DO response from core wells in the past was variable, but most wells
have shown a clear and consistent decline in DO since the air sparge system was shut
down in March 2002.

States Cooperative site. Of these, two have been determined to be currently active. All others
have been disconnected and the locations are hooked to city water. The two wells are
hydraulically up gradient of the site at distances of roughly 600 and 1,200 feet. Active and
inactive wells have been sampled and have not shown petroleum -related compounds such as
BTEX.
VI. Opinions - Based on the most recent groundwater sampling data and other file information the
following statements and opinions can be made:
A. The COC's are not contained on site; off site contamination extends to the adjacent property
to the south.
B. Portions of the petroleum plume associated with releases from the Southern States
Cooperative are likely commingled with the petroleum plume associated with the Former
Exxon Terminal directly across Jake Alexander Blvd. from the site.
C. There. is no data indicating groundwater impacts to residential areas in the vicinity.
