EPIDEMIOLOGY On August 30, 2006, the DHHS' Epidemiology Branch provided comments on'Sodium
Lactate, Sodium Bicarbonate, and Sodium Polymetaphosphate for groundwaterremediation. Dr. Luanne K. Williams
did not present any information that would preclude the use of these products for injection but did provide a health
risk analysis and worker safety precautions, which are in Part X of the attached permit.
REGIONAL OFFICE COMMENTS Art Barnhardt of the Fayetteville Regional Office recommends issuance of this
permit.

PERMIT ISSUANCE MEMO
TO: Debra Watts
THROUGH: Thomas Slusser /
FROM: John McCrav
RE:
Permit To Inject Sodium Lactate, Sodium Bicarbonate, and Sodium. Polymetaphosphate
solutions
NCDOT Priority Site No. 32
I recommend that Permit Number WI0600047 be issued to the NC DOT to inject Sodium Lactate, Sodium
Bicarbonate, and Sodium Polymetaphosphate solutions to remediate groundwater contaminated with chlorinated
aliphatic compound solvents.
SITE DESCRIPTION This site has been used as the location for an asphalt plant since the 1970's. Equipment
cleaning activities associated with asphalt testing at this site led to the release of chlorinated aliphatic compound
solvents.
HYDROGEOLOGIC DESCRIPTION The site is located along the western boundary of the Coastal Plain
Physiographic Province and is underlain primarily by silts and fine sands of Coastal Plain Sedimentary Formations.
Within the constraints of the site, these sediments compose a surficial aquifer and the hydraulically connected Black
Creek Aquifer.
EXTENT OF CONTAMINATION Contaminant distribution of 1,1-DCE for concentrations above the
NCGWQS, based on the most recent sampling event, is ovate in plan view (-250feet in length) with the long axis
corresponding to the North -South aligned A -A' cross section and is —125 ft wide. The plume extends to a depth
greater than the monitoring well network (>60ft bgl)(Fig. 17 and 18).
PROPOSED INJECTION The applicant proposes to inject, either by gravity or at a pressure not to exceed 50
psi, 200 gallons of solution composed of Sodium Lactate, Sodium Bicarbonate, and Sodium Polymetaphosphate into
the shallow groundwater zone through two existing monitoring wells and 400 gallons of solution into the deeper
groundwater zone through one monitoring well followed by 200 gallons of potable water per well during each event.
A total of four injection events are scheduled, resulting in a total injection volume of 3200 gallons of solution and
2400 gallons of potable water, or 5600 gallons of total injected fluids. The total volume of injectants comprises
approximately an average of <1 % of the pilot injection area.
HOW IT WORKS The main remedial activity of the injectant solution is to promote a more favorable
environment for naturally occurring halorespirating bacteria to continue consumption and degredation of the
contaminants. Sodium Bicarbonate is introduced to increase the pH of the groundwater to a more neutral level, and
the Sodium Lactate and Sodium Polymetaphosphate compounds provide other essential components for cell growth
such as energy, carbon, and phosphate.
MONITORING All monitoring wells located at the site will be used for monitoring for changes in
groundwater flow and contaminant concentrations during the injection events and afterward. One sampling event will
be conducted prior to injection and post injection monitoring will be done on a quarterly basis and will last for one
year.
