Former Modern Dry Cleaner Site — DSCA #65-0001
1. INJECTION ZONE
The area in which the injections are to occur is shown on the attached figure 5. The vertical
extent of the injection activities is proposed for the water table aquifer situated at
approximately 6 feet below grade to a depth of approximately 35 feet below grade. The
injections are only proposed to be conducted on the site property. There are no public or
private wells situated in the area of the injections. Based on a pumping test conducted on one
of the monitor wells with a screened interval situated between 20 and 30 feet below grade, the
groundwater velocity was determined to be approximately 0.5 feet per day. Based on the
nature of the sodium lactate (food grade material), the longevity of the injectant in the
groundwater is short term (approximately 1 year) before it is broken down and consumed by
indigenous bacteria.
2. HYDROGEOLOGIC EVALUATION
A) The Site is located in the Coastal Plain Physiographic Province and is underlain by a surficial
aquifer formation, the Castle Hayne, and Peedee Formations. The surficial aquifer is
unconfined and consists of interbedded gray, tan and brown sands and silts. The Castle
Hayne confining unit separates the surficial aquifer from the Castle Hayne Aquifer. The top
of the confining unit was encountered at approximately 40 feet below ground surface (bgs)
at the site. The deepest boring to 79 feet bgs did not fully penetrate the Castle Hayne
confining unit. The general groundwater flow direction across the site is to the north-
northwest.
B) Mostly gray and tan fine sand underlie the site from ground surface to approximately 40
feet bgs. A five-foot thick layer of light grey, calcareous clayey silt and limestone fragments
was encountered between 40 and 45 feet bgs, marking the top of the Castle Hayne
confining unit grading to green marine silt which was documented to 79 feet bgs by the
deepest boring, MW-WSP-2XD.
(C) Depth to Rock: undetermined
(D) Depth to mean seasonal water table: 4 to 6 feet bgs.
(E) Hydraulic Conductivity: 54 feet per day
Transmissivity: 11,300 gallons per day per foot
Storativity: 0.0025
Velocity: 0.5 feet per day
Monitor Well MW-WSP-5D was utilized for a pumping test to determine hydraulic
properties of the surficial aquifer. This well is 4 inches in diameter with a screened intake
set between 20 and 30 feet below grade. The well was pumped for approximately one and
a half hours at a rate of 15 gallons per minute. Calculations were based on data collected
from the pumping well and nearby observation wells. The data was plotted on a distance
versus drawdown semi -log graph to aid in calculating transmissivity and storativity.
(F) Groundwater in the water table aquifer flows to the north-northwest as determined by
surveyed monitor wells and groundwater travels at a rate of about 0.5 feet per day based on
pumping test data.
(G) Included as Attachment 1 are the monitor well logs for the site.
3. INJECTANT INFORMATION
A) The material to be injected is called WillClear+, which is a sodium lactate formulation made
with carbohydrates and fermentation metabolites manufactured by JRW Bioremediation to
stimulate anaerobic bioremediation of CVOC contaminants in groundwater. The MSDS is
included to this form as Attachment 2. The sodium lactate material will be mixed with 50%
water to lessen its viscosity to aid in the assimilation into the groundwater.
B) The source of the water used to dilute the sodium lactate will be from an on -site "clean"
well (Monitor Well MW-WSP-1D) which is located hydraulically upgradient of the former on -
site CVOC source areas. As such, the same formation water will eventually be placed back
into the ground with the food grade sodium lactate material. The log for Monitor Well MW-
WSP-11D is included in Attachment 1 and a groundwater sample analysis are summarized in
Table 2 attached to this form.
C) The sodium lactate material was selected since it is food grade material and it stimulates
anaerobic bioremediation of the CVOC impacted groundwater. The sodium lactate material
lasts for a short term and does not by itself break down into harmful constituents. As
indicated on the form, we propose to inject 3,575 gallons of sodium lactate diluted with
3,575 gallons of clean water obtained from an upgradient monitor well. The amount of
injectant proposed to be used is based on the area of the site and the depth between the
water table and the underlying confining unit referenced in Section 2 above. A calculation
sheet provided by JRW Bioremediation and included as Attachment 3 shows how the
injectant amount was derived.
D) The reductive dechlorination process being evaluated would involve the stimulation of
anaerobic bioremediation of the CVOCs by injecting food -grade sodium lactate into the
affected areas of the shallow overburden water table. The process works by stimulating
microbial growth and development, creating an anaerobic groundwater treatment zone,
and generating hydrogen through fermentation reactions which support the proliferation of
reducing bacterial colonies capable of dechlorinating PCE and other associated CVOC
daughter by-products. The CVOC reducing bacteria destroy the CVOCs by replacing chlorine
atoms within the solvent molecule with hydrogen atoms. The CVOC molecules eventually
breakdown through the successive removal of chlorine atoms to produce end -product
molecules of ethene and ethane as further illustrated in the following schematic below:

As is shown, the end products of the reductive dechlorination of TCE and the other
associated CVOCs include carbon dioxide, water, chlorine, ethene, and ethane.
E) The sodium lactate material becomes consumed by naturally occurring bacteria.
F) The lactate injections will travel with groundwater flow to the northwest. As discussed
above line C), the sodium lactate is quickly consumed in the groundwater by naturally
occurring bacteria.
4. INJECTION PROCEDURE
A) The Sodium lactate diluted with 50% water quantity to be injected during the initial event is
proposed to be 7,150 gallons. We are proposing to inject the aforementioned quantity of
sodium lactate through 6 injection wells and 25 soil borings advanced using a geoprobe rig.
The work will take approximately two weeks to complete. The attached figure 5 shows the
injection amounts per injection well and soil boring, and the locations, respectively and
Table 3 summarizes the injection quantities.
Subsequent injection events would be conducted in about six months with lesser injection
quantities to maintain the anaerobic environment in the groundwater to sustain the
bioremediation of the CVOC impacted groundwater. We are asking for a five year allowance
on injections for this site. The timing for subsequent follow up injection events will vary
based on the effectiveness of the initial event.
B) The average injection pressure will be about 30 psi.
C) Same as A) above.
5. FRACTURING PLAN
Not applicable to our application.
6. WELL CONSTRUCTION DETAILS
A) There are 6 existing wells to be utilized for the injection of the sodium lactate.
B) There are 25 proposed soil borings to be advanced using a geoprobe rig. Each soil boring
location will have an injection depth of 15 and 30 feet below grade.
C) The injection wells are existing.
D) The injection wells consist of PVC piping material and the depths are summarized on the
attached table 1.
E) See Table 1 and the well logs included in Attachment 1.
F) See well logs included in Attachment 1.
G) The injection wells are permanent, the soil borings are temporary direct push.
H) See well construction logs included in Attachment 1.
7. MONITORING PLAN
A) The target contaminants include tetrachloroethylene, trichloroethylene, cis-1,2-
dichloroethylene, trans-1,2-dichloroethylene and vinyl chloride.
B) We intend on collecting post -injection groundwater samples for analyses of volatile organic
compounds, metals, biological organic demand, chemical organic demand, sulfate,
nitrite/nitrate, gases (methane, ethane, and ethene), total organic carbon, and alkalinity.
Field parameters will be collected for dissolved oxygen, oxidation-reduction potential, pH,
temperature and conductivity.
C) Figure 4 shows the locations of the monitor wells relative to the site to be utilized for
monitoring the injection progress.
D) To monitor the effectiveness of the injection work, the 14 monitor wells listed below will be
sampled on a quarterly basis following the initial round of injection.
Shallow Overburden: Monitor Wells MW-3S, MW-4S, MW-5S, MW-6S, MW-7S and MW-
WSP-1S
