Report of Annual Groundwater Monitoring and
Treatment -System Effectiveness
Southern States Cooperative, Inc.
Statesville Fertilizer Plant
Statesville, North Carolina
October 24, 2017
Introduction
1.1 Site Location, Description, and History
The Southern . States Cooperative, Inc. (Southern States) fertilizer plant (the site) is located at
2582 Salisbury Highway (Old U.S. Highway 70), approximately 6 miles east of Statesville, North
Carolina (Figure 1). The site is developed with several buildings that include a fertilizer -manufacturing
building, an office building, a warehouse, several small support buildings, and multiple above -ground
storage tanks (Figure 2). The site is utilized for the manufacture, storage, and distribution of fertilizer.
The site is bordered to the north by Salisbury Highway; to the east by McNess Road, across which are
Fertie Technologies and Cardinal Logistics Management; to the south by U.S. Highway 70 Bypass (70
Bypass), across which are single-family residences; and to the west by undeveloped land. The 70 Bypass
crosses east to west through the southern portion of the site and separates approximately 13 acres from the
main property consisting of approximately 61 acres to the north.
Groundwater at the site exhibits ammonia and nitrate as a result of releases of liquid ammonium nitrate
that apparently flowed into four surface -water ponds formerly on the site. Two ponds were formerly
located approximately 1,000 feet soutliwest of the main plant, and two ponds were formerly located east
and southeast of the main plant. These ponds are -referenced in the. Corrective Action Plan (CAP) dated
January 28, 1994, submitted by- Canonie Environmental Services, Inc. (Canonie) to the North Carolina
Department of Environment, 'Health and Natural Resources (DEHNR), Division of Environmental
Management. The DEHNR approved the CAP in 1994. The CAP showed the extent of impact to
groundwater was defined with reasonable certainty. The objectives of the CAP were to remediate
groundwater and to prevent off -site migration of the contaminantplume. Canonie developed a
groundwater -sampling plan that established a semiannual groundwater -sampling schedule to monitor the
effectiveness of the CAP.
In an email dated April 30, 2014 to Duncklee & Dunham from Andrew Pitner of the Division of Water
Resources of the North Carolina Department of Environment and Natural Resources (now called the
Department of Environmental Quality, or DEQ), they agreed with our recommendation in the 2013
Annual Groundwater Monitoring and Treatment System Effectiveness Report to reduce the frequency of
groundwater monitoring from semiannual to annual.
On behalf of Southern States, Duncklee & Dunham researched nitrate -treatment technologies, evaluated
remedial alternatives for the subject site, and reported our findings to DEQ in the 2015 Annual
Groundwater Monitoring and Treatment System Effectiveness Report, dated November 9, 2015. We
recommended in the report that the continued operation of the existing treatment system appears to be the
most cost-effective approach to remove contaminant mass from groundwater and control off -site
migration of the plume. We met with DEQ personnel at the subject site on December 9, 2015 to discuss
the findings and remedial alternatives presented in our 2015 report. During this meeting, DEQ requested
and Southern States agreed to 1) begin semiannual sampling of the extraction wells, 2) collect vertical-

gradient data from the monitoring wells that surround RW-2, and 3) extend the operational period of the
treatment system throughout the year.
1.2 ,Summary of Remedial Actions
Groundwater -recovery wells RW-2, RW-5r and RW-6 were constructed as part of the CAP. These wells
pump groundwater to a treatment system, in which the pH is adjusted by adding a caustic solution prior to
discharge into Fourth Creek (Figure 3).
The groundwater -treatment system is permitted under the National Pollution Discharge Elimination
System (NPDES) program. Duncklee & Dunham conducts bi-monthly site visits when the system is
j operational to monitor the treatment system and ensure it operates within the permitted discharge limits.
We collect effluent water samples bi-monthly and report the data to DEQ on monthly Discharge
Monitoring Reports (DMRs).
Treatment -System Maintenance and Monitoring
The groundwater -treatment system operated during this reporting period from July 19, 2016, to February
24, 2017, when Duncklee & Dunham's North. Carolina licensed Grade I Wastewater Operator (operator)
observed the pH monitoring system providing a false high of 7.0.8 when the operator measured a pH of
5.69 from the effluent port. The operator was unable to accurately calibrate the pH probe and, after a
discussion with the manufacturer, determined the probe was beyond repair. The operator ordered a
replacement pH probe for the monitoring system and installed it on April 17, 2017. Once the system was
re -activated, the operator observed the primary lift station pump to be inoperable. Plant personnel
ordered parts and repaired the system. Once repairs were complete, the operator re -activated the system
on May 12, 2017. On June 20, 2017, plant personnel observed caustic solution bypassing the peristaltic
pump that regulates caustic intake into the wet well, which caused the pH to spike. The system was shut
off until a replacement back -pressure valve could be ordered and installed. The back -pressure valve was
replaced by plant personnel and the operator re -activated the system on July 26, 2017. During routine
maintenance, the operator observed the lift station pump to be damaged and unable to discharge on
August 28, 2017. He worked with on -site personnel to repair the damaged airline and solenoid and re-
activate the system that day. Based onrecovery well flow -volume readings, we believe the system was
inoperable between August 11 and August 28, 2017. A summary of the volumes of water removed by
each extraction well during this reporting period is detailed below.

Duncklee & Dunham collects water samples bi-annually from the three recovery wells. We collect the
samples from spigots located near the wellheads and have the samples tested for nitrate nitrogen
according to EPA Method 300.0 and ammonia nitrogen according to EPA Method SM4500-NH3-G. The

results are summarized in Table 1 and the laboratory analytical reports and chain -of -custody records are
in Appendix A.
In accordance with the NPDES permit, the operator collected treatment system effluent samples bi-
monthly for analysis of total suspended solids (TSS) according to Method SM 2540D and ammonia
nitrogen according to EPA Method SM 4500-NH3-G. The operator also collected monthly effluent
samples for analysis of copper according to EPA Method 200.7, phosphorus according to. Standard
- ; Method SM4500-P-F, and total Kjeldahl nitrogen, nitrate nitrogen, and chloride according to EPA
Method 300. We submitted the samples for analysis to Prism Laboratories, Inc. (Prism), an analytical
laboratory certified by DEQ. The operator also collected effluent samples for analysis of Ceriodaphnia
chronic toxicity (chronic toxicity) according to the December 2010 North Carolina Phase II Chronic
Whole Effluent Toxicity test procedure. We collected chronic toxicity samples in February and May 2017
and submitted these samples to ESC Lab Sciences (ESQ. We submitted quarterly chronic toxicity
reports to DEQ as required by the NPDES permit.
3 Monitoring Well -Sampling Activities and Results
Duncklee & Dunham conducted annual groundwater -monitoring activities on July 26 to 28, 2017. We
purged and re -sampled monitoring well K65W6E on August 30, 2017 to verify the abnormally low nitrate
concentrations detected in the sample collected during the7July event. Prior to well purging and sampling,
we measured depths to the water table with an electric water -level probe and recorded these data on field -
sampling data sheets. These depths and respective water -table elevations are; summarized on Table 2. A
potentiometric map that illustrates the direction of groundwater flow for the July 2017 sampling event is
presented as Figure 4. The direction of groundwater flow during the event was S28°W and the average
hydraulic gradient was 0.049 ft/ft which is consistent with historical trends.
3.1 Monitoring Nell -Sampling Methodology
Duncklee & Dunham collected groundwater samples from 11 of the 14 monitoring wells during the July
2017 sampling event. We could not find K65W6D, although this well has historically been dry during
sampling events since February 1993. Monitoring wells K65W7C and K65W7G were dry during this
event.
Duncklee & Dunham purged the wells and collected samples with a submersible, electric pump fitted
with new, disposable polyethylene tubing from the wells greater than 60 feet in depth, and used a
peristaltic pump fitted with new tubing for the wells less than 60 feet in depth. We collected the
groundwater samples using low -flow sampling techniques. During the sampling process, we recorded
field measurements for dissolved oxygen (DO), oxidation-reduction potential (ORP), pH, temperature,
turbidity, and electrical conductivity (Table 3).
Duncklee & Dunham discharged the groundwater samples directly into labeled laboratory -provided
containers, recorded the samples on a chain -of -custody form, and transported the containers to Prism in a
cooler filled with ice. Prism tested the samples for nitrate according to EPA Method 300.0 and ammonia
nitrogen according to Standard Method SM4500-NH3-G. The laboratory analytical reports and chain -of -
custody records are in Appendix A.

3.2 Results from ,Sampling Event
L j Nitrate isoconcentration maps are presented as Figures 5 and 6. Nitrate and ammonia concentrations are
displayed on Cross Sections A -A' and B-B', Figures 7 and 8, respectively. The test results are
�I summarized on Table 3 and graphs of the nitrate and ammonia trends over time are in Appendix B.
3.2.1 Nitrate Results and Trends
We observed the following with respect to the nitrate results.
• Samples from saprolite wells K65W6A, -613, -6N, -7F, and -7J exhibited nitrate at concentrations that
exceed the North Carolina groundwater quality standard (2L standard) of 10 mg/L.
C�{ • The sample collected from saprolite well K65W613 exhibited nitrate at a concentration of 80 mg/L.
This is the highest concentration detected in samples from this well since May 2003.
• The nitrate concentration in the sample from saprolite well K65W7F decreased from a high of 98
mg/L in May 2016 to within historical concentrations at 50 mg/L in July 2017.
• Samples from the bedrock monitoring well K65W6E, located near the former location of Pond B,
have exhibited an increasing trend in nitrate concentrations since May 1997. The nitrate
concentration in the July 2017 sample decreased to 74 mg/L. Due to this abnormally low nitrate
concentration, we purged 77 gallons from the well and re -sampled it in August 2017. The August
2017 sample exhibited nitrate at a concentration of 330 mg/L, which is the highest nitrate
. concentration detected in this well.
• Samples from bedrock wells K65W7K and K65W7L, located in the center of the plume, exhibited
nitrate at concentrations that exceeded the 2L standard, but remain consistent with historical
concentrations.
• Samples from bedrock delineation well K65W7H, at the southern extent of the plume, have not
( exhibited nitrate at concentrations that exceed the 2L standard. However, the samples collected from
this well have exhibited a gradual increasing trend in nitrate concentrations since the well was
constructed in 2008.
3.2.2 Ammonia Results and Trends
1
We observed the following with respect to the ammonia results.
• The sample collected from saprolite well K65W7J in July 2017 exhibited ammonia at a concentration
that exceeds the Interim Maximum Allowable Concentration (IMAC) of 1.5 mg/L. Ammonia
concentrations in samples from K65W7J have exceeded the current IMAC since April 2009 but have
not exhibited any significant changes in concentrations since 2011.
• The samples from the bedrock wells located in the center of the plume, K65W7K and K65W7L,
exhibited ammonia at concentrations that exceeded the 2L standard. The concentrations in the
samples from both wells are consistent with previous data. Similar.

This data package contains the analytical results for the project identified above and includes a Case Narrative, Sample
Results and Chain of Custody. Unless otherwise noted, all samples were received in acceptable condition and processed
according to the referenced methods.
Data qualifiers are flagged individually on each sample. A key reference for the data qualifiers appears at the end of this case
narrative.
Narrative Notes:
This is a Revised Report and supercedes the original laboratory report dated 08/03/17. The sample ID
originally reported as K65W6W was corrected to report as K65W6N. Also, data was initially reported for
sample IDs K65W6M and K65W6N incorrectly. Confimation analyses showed that the original data had
been switched. Results for those samples have been corrected.
Please call if you have any questions relating to this analytical report.

Report of Annual Groundwater Monitoring and
Treatment System Effectiveness
Southern States Cooperative, Inc.
Statesville Fertilizer Plant
Statesville, North Carolina
1. Introduction
1.1 Site Location, Description and History
The Southern States Cooperative, Inc. (Southern States) fertilizer plant (the site) is located at
2582 Salisbury Highway (Old U.S. Highway 70), approximately 6 miles east of Statesville, North
Carolina (Figure 1). The site consists of several buildings that include a fertilizer -manufacturing building,
an office building, warehouse, and several, small, support buildings (Figure 2). The site is utilized for the
manufacture, storage, and distribution of fertilizer.
The site is bordered to the north by old U.S. Highway 70; to the east by Fertie Technologies and Cardinal
Logistics Management; to the south by U.S. Highway 70 Bypass (70 Bypass), across which are
J residential properties; and to the west by undeveloped land. The 70 Bypass crosses east to west through
the southern portion of the site and separates approximately 13 acres from the main property to the north.
Groundwater at the site has been adversely impacted by a release of liquid ammonium nitrate from
several surface -water ponds formerly on the site. Two ponds were formerly located approximately 1,000
feet southwest of the main plant. Two additional ponds were formerly located east and southeast of the
main plant. These ponds are referenced in the Corrective Action Plan (CAP) dated January 28, 1994,
submitted by Canonie Environmental Services, Inc. (Canonie) to the North Carolina Department of
Environment, Health and Natural Resources (DEHNR), Division of Environmental Management. The
DEHNR approved the CAP in 1994 and based on the CAP, the assessment and impact of groundwater
contamination was defined with reasonable certainty. The objectives of the CAP were to remediate
groundwater and to prevent off -site migration of the . contaminant plume. Canonie developed a
groundwater -sampling plan that established a semiannual groundwater -sampling schedule to monitor the
effectiveness of the CAP.
In an email dated April 30, 2014 to Duncklee & Dunham from Andrew Pitner of the North Carolina
Department of Environment and Natural Resources (now called the Department of Environmental
Quality, or DEQ), Division of Water Resources, they agreed with our recommendation in the 2013
Annual Groundwater Monitoring and Treatment System Effectiveness Report to reduce the frequency of
groundwater monitoring from semiannual to annual.
On behalf of Southern States, Duncklee & Dunham researched nitrate -treatment technologies and
evaluated remedial alternatives for the subject site and reported our findings to DEQ in the 2015 Annual
Groundwater Monitoring and Treatment System Effectiveness Report, dated November 9, 2015. We
recommended in the report that the continued operation of the existing treatment system appears to be the
most cost-effective approach to remove contaminant mass from groundwater and control off -site
migration of the plume. We met with DEQ personnel at the subject site on December 9, 2015 to discuss
the findings and remedial alternatives presented in our 2015 report. During this meeting, Southern States,
Duncklee & Dunham and DEQ personnel agreed to begin semiannual sampling of the extraction wells,
the collection of vertical gradient data from monitoring wells that surround RW-2, and to extend the
operational period of the treatment system throughout the year.

1.2 Summary of Remedial Actions
Groundwater -recovery wells RW-2, RW-5r and RW-6 were constructed as part of the CAP. The
recovery wells pump groundwater to a treatment system where the pH is adjusted by adding a caustic
solution prior to discharge into Fourth Creek (Figure 3)."
The groundwater -treatment system is permitted under the National Pollution Discharge Elimination
System (NPDES) program. Duncklee & Dunham conducts bi-monthly site visits when the system is
operational to monitor the treatment system and ensure it operates within the permitted discharge limits.
! We collect effluent water samples bi-monthly and report the data to DEQ on monthly Discharge
Monitoring Reports (DMRs). k
2. Treatment System Monitoring
The groundwater -treatment system operated during this reporting period from November 3, 2015, to
February 1, 2016, when the North Carolina licensed Grade I Wastewater Operator (operator) observed the
lift station pumps to be inoperable. Plant personnel ordered replacement parts and conducted repairs to
the system. Once repairs were complete, the system was re -activated on April 20, 2016. The treatment
system operated until June 23, 2016, when the operator shut the system off until the caustic solution tank
was refilled. The operator re -activated the system on June 27, 2016. On June 29, 2016, plant personnel
observed a leak in the caustic pump that injects caustic solution into the wet well. The system was shut
off until a replacement pump could be ordered and installed. The pump was replaced by plant personnel
and the operator re -activated the system on July 19, 2016.
As a result of the December 2015 meeting between Southern States and DEQ, we now collect samples bi-
annually from the three recovery wells. The samples are collected from spigots located near the
wellheads and tested for nitrate nitrogen according to EPA Method 300.0 and ammonia nitrogen
according to EPA Method SM4500-NH3-G. The results are summarized in Table 1 and the laboratory
analytical reports and chain -of -custody records are in Appendix A.
In accordance with the NPDES permit, the operator collected effluent samples bi-monthly for analysis of
total suspended solids (TSS) according to Method SM 2540D and ammonia nitrogen according to EPA
Method SM 4500-NH3-G. The operator also collected monthly effluent samples for analysis of copper
(EPA Method 200.7), phosphorus (Method SM4500-P-F), total Kjeldahl nitrogen, nitrate nitrogen, and
chloride, all by EPA Method 300. We submitted the samples for analysis to Prism Laboratories, Inc.
(Prism), an analytical laboratory certified by DEQ. The operator also collected effluent samples for
analysis of Ceriodaphnia chronic toxicity (chronic toxicity) according to the December 2010 North
Carolina Phase H Chronic Whole Effluent Toxicity test procedure. We collected chronic toxicity samples
in May 2016 and submitted these samples to ESC Lab Sciences (ESQ. We submitted quarterly chronic
toxicity reports to DEQ as required by the NPDES permit.

3. Monitoring Well -Sampling Activities and Results
Based on the December 2015 meeting, we collected water levels from monitoring wells K65W7F,
K65W7G, and K65W7H on December 22, 2015, and shut off RW-2 until January 7, 2016. During the
January 2016 site visit, we collected an additional round of water levels prior to re -activating RW-2.
The water -level data were used to calculate the vertical gradients from the well clusters. The results were
submitted to DEQ on April 28, 2016.
Duncklee & Dunham conducted annual groundwater -monitoring activities on May 25 to 26, 2016. Prior
to well purging and sampling, we measured depths to the water table with an electric water -level probe
and recorded these data on field -sampling data sheets. These depths and respective water -table elevations
are summarized on Table 2. A potentiometric map that illustrates the direction of groundwater flow for
the May 2016 sampling event is presented as Figure 4. The direction of groundwater flow during the
event was to the south-southwest and the average hydraulic gradient was 0.053 ft/ft.
3.1 Monitoring Well -Sampling Methodology
Duncklee & Dunham collected groundwater samples from K65W7F, K65W7G, and K65W7H during a
site visit on January 7, 2016. We submitted the laboratory results to DEQ along with the calculated
vertical gradients on April 28, 2016.
Duncklee & Dunham collected groundwater samples from 11 of the 14 monitoring wells during the May
2016 sampling event. Monitoring wells K65W6D, K65W7C, and K65W7G were dry during this event.
Duncklee & Dunham purged the wells and collected samples with a submersible, electric pump fitted
with new, disposable polyethylene tubing from the wells greater than 60 feet in depth, and used a
peristaltic pump fitted with new tubing for the wells less than 60 feet in depth. We collected the
! groundwater samples using low -flow sampling techniques. During the sampling process, we recorded
field measurements for dissolved oxygen (DO), oxidation-reduction potential (ORP), pH, temperature,
turbidity, and electrical conductivity (Table 3).
Duncklee & Dunham discharged the groundwater samples directly into labeled laboratory -provided
containers, recorded the samples on a chain -of -custody form, and transported the containers to Prism in a
cooler filled with ice. Prism tested the samples for nitrate according to EPA Method 300.0 and ammonia
nitrogen according to EPA Method SM4500-NH3-G. The laboratory analytical reports and chain -of -
custody records are in Appendix A.
3.2 Results from Sampling Event
Nitrate isoconcentration. maps are presented on Figures 5 and 6. Nitrate and ammonia concentrations are
displayed on Cross Sections A to A' and B to B', Figures 7 and 8, respectively. The test results are
summarized on Table 3 and graphs of the nitrate and ammonia trends over time are in Appendix B.

3.2.1 Nitrate Results and Trends
We observed the following with respect to the nitrate results.
• Samples from saprolite wells K65W6A, -613, -6N, -717, and -7J exhibited nitrate at concentrations that
exceed the North Carolina groundwater quality standard (2L standard) of 10 mg/L.
• Samples from the saprolite well K65W7G have exhibited an increasing trend in nitrate concentrations
since May 2014. The sampled collected in May 2015 exhibited a peak in nitrate concentrations at
248 mg/L, which is the highest nitrate concentration detected in a sample from this well. We
collected additional samples from K65W7F, K65W7G, and K65W7H during a site visit on January 7,
2016. During this January event, the sample from K65W7G decreased in nitrate concentration to 56
mg/L but remains above historical concentrations.
• The nitrate concentrations in the samples from saprolite wells K65W613, -6N, and -717 exceeded the
lab's calibration ranges and are estimations made by the lab. The estimated concentrations for the
samples from wells K65W613 and K65W6N are within historical ranges, but the estimated
concentration from the sample collected from K65W7F increased to 98 mg/L, which is the highest
concentration detected in samples from this well since February 1996.
• The nitrate concentration in the sample from bedrock monitoring well K65W6E, located near the
former location of Pond B, increased to 320 mg/L, which is the highest concentration detected from
this well.
• Samples from bedrock wells K65W7K and K65W7L, located in the center of the plume, exhibited
nitrate at concentrations that exceeded the 2L standard, but remain consistent with historical
concentrations.
• Samples from bedrock delineation well K65W7H, at the southern extent of the plume, have not
exhibited nitrate at concentrations that exceed the 2L standard since the well was constructed in 2008.
3.2.2 Ammonia Results and Trends
We observed the following with respect to the ammonia results.
• The samples from saprolite wells K65W7G in January 2016 and K65W7J in May 2016 exhibited
ammonia at concentrations that exceed the Interim Maximum Allowable Concentrations (IMACs)
standard of 1.5 mg/L. Ammonia concentrations in samples from K65W7J have exceeded the IMACs
standard since April 2009. The concentration in the January 2016 sample from K65W7G decreased
from 81.2 mg/L in 2015 to 6.7 mg/L in 2016.
• The samples from the bedrock wells located in the core of the plume, K65W7K and K65W7L,
exhibited ammonia at concentrations that exceeded the IMACs standard. The concentrations in the
samples from both wells are consistent with previous data.
• Samples from down -gradient plume delineation bedrock well K65W7H, in the southwestern portion
of the site, have not exhibited ammonia since the well was constructed in 2008.

4. Recommendations
Based on the information presented above, Duncklee & Dunham recommends the following:
• Continue to operate the groundwater -treatment system in accordance with the CAP.
• Test groundwater samples collected from the three recovery wells for nitrate and ammonia on a bi-
annual basis.
• Continue the groundwater -monitoring program on an annual basis and conduct the next sampling
event in May 2017.

Report of Annual Groundwater Monitoring and
Treatment System Effectiveness
Southern States Cooperative, Inc.
Statesville Fertilizer Plant
Statesville, North Carolina
Introduction
L-I Site Location, Description and History
The Southern States Cooperative, Inc. (Southern States) fertilizer plant (the site) is located at
2582 Salisbury Highway (Old U.S. Highway 70), approximately six miles east of Statesville, North
Carolina (Figure 1). The site consists of several buildings that include a fertilizer -manufacturing building,
an office building, and several, small, support buildings (Figure 2). The site is utilized for the
manufacture, storage, and distribution of fertilizer.
The site is bordered to the north by old U.S. Highway 70, to the east by a Purina Feed Mill, to the south
by residential properties, and to the west by undeveloped land. The U.S. Highway 70 Bypass (70 Bypass)
crosses east to west through the southern portion of the site and separates approximately 13 acres from the
main property to the north.
Groundwater at the site has been adversely impacted by a release of liquid ammonium nitrate from
several former surface -water ponds. Two ponds (Former Pond No. 1 and No. 2 on Figure 2) were located
approximately 1,000 feet southwest of the main plant. Two additional ponds (Former Ponds A and B,
Figure 2) were located east and southeast of the main plant. These ponds are referenced in the Corrective
Action Plan (CAP) dated January 28, 1994, submitted by Canonie Environmental Services, Inc. (Canonie)
to the North Carolina Department of Environment, Health and Natural Resources (DEHNR), Division of
Environmental Management. The DEHNR approved the CAP in 1994 and based on the CAP, the
assessment and impact of groundwater contamination was defined with reasonable certainty. The
objectives of the CAP were to remediate groundwater and to prevent off -site migration of the contaminant
plume. Canonie developed a groundwater -sampling plan that established a semiannual groundwater -
sampling schedule to monitor the effectiveness of the CAP.
In an email to Duncklee & Dunham from the North Carolina Department of Environment and Natural
Resources (DENR), Division of Water Resources (now called the Department of Environmental Quality)
dated April 30, 2014, they agreed with our recommendation in the 2013 Annual Groundwater Monitoring
and Treatment System Effectiveness Report to reduce the frequency of groundwater monitoring from
semiannual to annual. In this email, DENR also requested completion of an updated receptor survey and
analysis of the effectiveness of the current remediation strategy, and of other treatment options to reduce
contaminant concentrations and to reduce the potential for contaminants to migrate off -site or to surface
waters.
Duncklee & Dunham conducted a receptor survey of surrounding properties within 2,000 feet of the on -
site source areas in July 2014. We reported our findings to DENR in the 2014 Annual Groundwater
Monitoring and Treatment System Effectiveness Report, dated October 10, 2014.

1.2 Summary of Remedial Actions
Groundwater -recovery wells RW-2, RW-5 and RW-6 were constructed as part of the CAP. RW-5 was
taken out of service prior to 2005 due to low or no groundwater recovery and was replaced by RW-5r in
September 2008. The recovery wells pump groundwater to a treatment system where the pH is adjusted
by adding a caustic solution prior to discharge into Fourth Creek (Figure 3).
The groundwater -treatment system is permitted under the National Pollution Discharge Elimination
_- System (NPDES) program. Duncklee & Dunham conducts bi-monthly site visits when the system is
operational to monitor the treatment system and ensure it operates within the permitted discharge limits.
We collect effluent water samples bi-monthly and report the data to the DENR on monthly Discharge
Monitoring Reports (DMRs).
2 Treatment System Monitoring
The groundwater -treatment system operated during this reporting period from November 3, 2014, to
March 31, 2015, when a North Carolina licensed Grade I Wastewater Operator (operator) shut off the
system for the summer months. The system will be restarted by the operator in November 2015.
In accordance with the NPDES permit, the operator collected effluent samples bi-monthly for analysis of
total suspended solids (TSS) according to Method 2540D and ammonia nitrogen according to EPA
Method 350.1. The operator also collected monthly effluent samples for analysis of copper (EPA Method
200.7), chloride (Method SM 4500-C1-E), TSS, ammonia nitrogen, total Kjeldahl nitrogen, nitrate
nitrogen and phosphorus, all by EPA Method 300 series. We submitted the samples for analysis to Pace
Analytical Services, Inc. (Pace), an analytical laboratory certified by DENR. The operator also collected
effluent samples for analysis of Ceriodaphnia chronic toxicity (chronic toxicity) according to the
December 2010 North Carolina Phase 11 Chronic Whole Effluent Toxicity test pr_oeedure. Chronic
toxicity samples we collected in November 2014 were analyzed by a—ceLand-samples-collected_in-January
2015 and February 2015 were analyzed by ESC Lab _Sciences (ESC).'We submittied q rterly chronic
to icrty_reports to DENR as requir�ed'by theMFDES pequif .
3 Groundwater -Sampling Activities and Results
Duncklee & Dunham conducted groundwater -monitoring activities on May 20 to 22, 2015. Prior to well
purging and sampling, we measured depths to the water table with an electric water -level probe and
recorded these data on field -sampling data sheets. These depths and respective water -table elevations are
summarized on Table 1. A potentiometric map that illustrates the direction of groundwater flow for the
May 2015 sampling event is presented as Figure 4. The direction of groundwater flow during the event
was to the south-southwest and the average hydraulic gradient was 0.032 ft/ft.
3.1 Groundwater -Sampling Methodology
Duncklee & Dunham collected groundwater samples from 12 of the 14 monitoring wells during the May
2015 sampling event. Monitoring wells K65W6D and K65W7C were dry during this event.

Duncklee & Dunham purged the wells and collected samples with a submersible, electric pump with new,
disposable polyethylene tubing from the wells greater than 35 feet in depth, and used a peristaltic pump
with new tubing for the wells less than 35 feet in depth. We collected the groundwater samples using
low -flow sampling techniques. During the sampling process, we recorded field measurements for
dissolved oxygen (DO), oxidation-reduction potential (ORP), pH, temperature, turbidity, and electrical
- conductivity (Table 2). The casing to K65W6A is bent approximately two feet below land surface and a
submersible pump cannot advance past the damaged casing.;,Due_tue t hallow_water table in_K65_W6A;
we.. were: ,ab,le to lower, tubing to the mid=point__of the well screen and_collec-La sample by _lowmflo 0

Duncklee & Dunham discharged the groundwater samples directly into labeled laboratory -provided
containers, recorded the samples on a chain -of -custody form, and transported the containers to Pace in a
cooler filled with ice. Pace tested the samples for nitrate according to EPA Method 353.2 and ammonia
according to EPA Method 350.1. The laboratory analytical reports and chain -of -custody records are in
Appendix A.
3.2 Results from Sampling Event
Nitrate isoconcentration maps are presented on Figures 5 and 6. Nitrate and ammonia concentrations are
displayed on Cross Sections A to A' and B to B', Figures 7 and 8, respectively. The test results are
summarized on Table 2 and graphs of the nitrate and ammonia trends over time are in Appendix B.
3.2.1 Nitrate Results and Trends
We observed the following with respect to the nitrate results.
• Samples from saprolite wells K65W6A, -6B,-6N,.-7F, 7G, and -7J exhibited nitrate at concentrations
that exceed the North Carolina groundwater quality standard (2L standard) of 10 mg/L.
• The nitrate concentration continues to increase in the sample collected from the saprolite plume well
K65W7G at the southern extent of the plume. The concentration of 248 mg/L is the highest
concentration ever detected in samples from this well.
• The nitrate concentration in the sample from bedrock monitoring well K65W6E, located near former
Pond B, decreased slightly from the two previous events, though the overall nitrate concentrations
continue to trend upward in the samples from this well.
• Samples from bedrock wells K65W7K and K65W7L, located in the core of the plume, exhibited
nitrate at concentrations that exceeded the 2L standard, but remain consistent with levels detected
since April 2008.
• Samples from bedrock delineation well K65W7H, at the southern extent of the plume, have not
exhibited nitrate at concentrations that exceed the 2L standard since the well was constructed in 2008.

samples from both of these wells are consistent with previous data.
• Samples from down -gradient plume delineation bedrock well K65W7H, in the southwestern portion
of the site, have not exhibited ammonia since the well was constructed in 2008.
4 Evaluation of Remedial System Effectiveness and Remedial. Options
As requested by the Department of Environmental Quality, Duncklee & Dunham completed an analysis
of the effectiveness of the current remediation strategy. We also addressed other, potential, treatment
options to reduce contaminant mass and the potential for contaminants to migrate off -site.
As referenced in Section 1.2, the current remediation system consists of recovery wells RW-2, -5r, and -6
that pump groundwater to a caustic injection system, where water is treated to balance the pH levels prior
to discharge into Fourth Creek. Currently, we operate the system between November 1st and April 1st.
The system is off seven months of the year when historically the water table has dropped below the
effectiveness of the recovery wells.
Each recovery well is at a different location within the contaminant plume. RW-5r is the northernmost
well and is located downgradient of two suspected source areas, former ponds A and B. RW-6 is
centralized within the contaminant plume and is located between RW-5r and RW-2. RW-2 is located at
the downgradient end of the nitrate plume to control offsite migration.
4.1 Performance of Treatment System
Data indicate the treatment system has successfully removed dissolved -phase nitrate mass. The system
removed approximately 115.8 million gallons of water and 52,650 pounds of nitrate for the operational
period of October 2005 to March 2015.
4.2 Remedial Options
Duncklee & Dunham researched nitrate -treatment technologies and evaluated remedial alternatives for
this site. Table 3 presents a description of the best available in situ and ex situ remediation options for the
site. As presented in Table 3, the remedial technologies available are either impractical (permeable
reactive barriers) or cost -prohibitive (reverse osmosis, et.al.). Continued operation of the existing
treatment system appears to be the most cost-effective approach to remove contaminant mass from
groundwater and control off -site migration of the plume.

5 Recommendations
Based on the information presented above, Duncklee & Dunham recommends the following:
• Operate the groundwater -treatment system in accordance with the CAP and NPDES permit.
• Test groundwater samples collected from the three recovery wells for nitrate and ammonia on an
annual basis.
• Continue with the annual groundwater -monitoring program and conduct the next sampling event in
May 2016.

1 Introduction
1.1 Site Location, Description and History
The Southern States Cooperative, Inc. (Southern States) fertilizer plant (the site) is located at
2582 Salisbury Highway (Old U.S. Highway 70), approximately six miles east of Statesville, North
Carolina (Figure 1). The site consists of several buildings that include a fertilizer -manufacturing building,
an office building, and several, small, support buildings (Figure 2). The site is utilized for the
manufacturing, storage, and distribution of fertilizer.
The site is bordered to the north by old U.S. Highway 70, to the east by Purina Feed Mill, to the south
by residential properties, and to the west by undeveloped land. The U.S. Highway 70 Bypass (70 Bypass)
crosses east to west through the southern portion of the site and separates approximately 13 acres from the
main property to the north (Figure 2).
Groundwater at the site has been impacted by a release of liquid ammonium nitrate from several former
surface -water impoundments. Two impoundments (Former Pond No. 1 and No. 2) were located
approximately 1,000 feet southwest of the main plant (Figure 2). Two additional surface water
impoundments (Former Ponds A and B, Figure 2) were located east and southeast of the main plant.
These impoundments are referenced in the Corrective Action Plan (CAP) dated January 28, 1994,
submitted by Canonie Environmental Services, Inc. (Canonie) to the North Carolina Department of
Environment, Health and Natural Resources (DEHNR), Division of Environmental Management. The
DEHNR approved the CAP in 1994 and based on the CAP, the assessment and impact of groundwater
contamination was defined with reasonable certainty.
The objectives of the CAP were to remediate groundwater and to prevent off -site migration of the
groundwater contamination plume. Canonie developed a groundwater -sampling plan that established a
semiannual groundwater -sampling schedule to monitor the effectiveness of the CAP.
In an email from the North Carolina Department of Environment and Natural. Resources Division of
Water Resources (DENR) dated April 30, 2014, they agreed with our recommendation in the 2013
Annual Groundwater Monitoring and Treatment System Effectiveness Report to reduce the groundwater
monitoring frequency from semiannual to annual. In this email, DENR also requested completion of an
updated receptor survey and analysis of the effectiveness of the current remediation strategy and of other
treatment options to reduce contaminant concentrations and to reduce the potential for contaminants to
migrate off -site or to surface waters.
1.2 Summary of Remedial Actions
Groundwater -recovery wells RW-2, RW-5 and RW-6 were constructed as part of the CAP. RW-5 was
taken out of service prior to 2005 due to low or no groundwater recovery and was replaced by RW-5r in
September 2008. The recovery wells pump groundwater to a treatment system where the pH is adjusted
by adding a caustic solution prior to discharge into Fourth Creek (Figure 3).

and Treatment System Effectiveness

The groundwater -treatment system is permitted under the National Pollution Discharge Elimination
System (NPDES) program. Duncklee & Dunham conducts bi-monthly site visits when the system is
operational to monitor the treatment system and ensure it operates within the permitted discharge limits.
We collect effluent water samples bi-monthly and report the data to the DENR on monthly Discharge
Monitoring Reports (DMRs).
2 Treatment System Monitoring
The groundwater -treatment system operated during this reporting period from January 1, 2014, to March
' 31, 2014, when a North Carolina licensed Grade I Wastewater Operator (operator) shut off the system for
the summer months. The system will be restarted by the operator in November 2014.
In accordance with the NPDES permit, the operator collected effluent samples bi-monthly for analysis of
total suspended solids (TSS) according to Method 2540D and ammonia nitrogen according to EPA
Method 350.1. The operator also collected monthly effluent samples for analysis of copper (EPA Method
200.7), chloride (Method SM 4500-C1-E), TSS, ammonia nitrogen, total Kjeldahl nitrogen, nitrate
nitrogen and phosphorus all by EPA Method 300 series. We submitted the samples for analysis to Pace
Analytical Services, Inc. (Pace), an analytical laboratory certified by DENR. We submitted monthly
DMRs to DENR as required by the NPDES permit.
3 Receptor Information Update
Duncklee & Dunham conducted a field reconnaissance in July 2014 to update water -supply information
of properties within 2,000 feet of Former Ponds A and B. We drove to each property to look for evidence
of water -supply wells and to verify connection to public water supplies. We observed one water -supply
well at the site (Figure 2) and two water -supply wells off -site within 2,000 feet of the former ponds
(Figure 4 and Table 1). The on -site well is used for industrial production and fire suppression. The off -
site wells are located northwest and northeast of the site at residential properties located adjacent to
Salisbury Highway. Both of the off -site wells are topographically upgradient from the site, and based on
the groundwater -flow direction at the site (Figure 5), these wells are hydraulically upgradient of the
plume.
Potable water is provided to the site and surrounding properties by either the City of Statesville or the
Iredell Water Corporation (IWC). IWC is a membership -owned non-profit utility and their water source
consists of a network of 33 supply wells located within the northern half of Iredell County. The closest
supply well operated by IWC is designated as Well #16 and is located approximately one and one half
miles north of the site. A map showing the location of this well in relation to the site is in Appendix A.
Water lines operated by IWC are located within the 2,000-foot area that surrounds the site. According to
IWC, they supply water to all the residential properties located along Big Forest Drive, Brentbrook Road,
- Camp Oak Road, Mcness Road, and Morehead Road (Figure 4).
According to the Statesville East topographic quadrangle (Figure 1) and the Iredell County GIS website,
the nearest surface -water body is an intermittent stream located approximately 200 feet west of the
western extent of the shallow contaminant plume. The nearest perennial surface -water body is a pond
located approximately 1,400 feet west of the western extent of the plume.

Dear Mr. Dann:
The referenced report was received in this office on October 16, 2014. 1 have reviewed the
report and have placeddit in. the Division's permit files, The next report is due.in this office
by October 30, 2015.
Thank you for updating the site Receptor Survey in this report. Duncklee and Dunham have
recommended proceeding With the existing -on site remediation system. While the report
addresses the concentrations levels are continuing to decrease, it does not address the
request from the a=mail response of April 30; 2014, which asked for evaluation of the
system. Please -provide an account of the effectiveness of the current remediation strategy.
Also the report. does not provide information as to other methods'of remedial actions that
might be useful for onsite wells that continue to remain above 2L standards for.both Nitrate
and Ammonia.. .
In your next report; please provide a brief.analysis of other treatment options that might be
appropriate for this site to reduce groundwater contamination levels and. prevent migration
of contaminants off site: or to surface waters. Otherwise, provide information supporting the
continuation of the current remediation system present on this site.

Duncklee & Dunham conducted groundwater -monitoring activities on May 28 to 29, 2014. Prior to well
purging and sampling, we measured depths to the water table with an electric water level probe and
recorded this data on field -sampling data sheets. These depths and respective water -table elevations are
summarized on Table 2. A potentiometric map that illustrates the direction of groundwater flow for the
May 2014 sampling event is presented as Figure 5. The direction of groundwater flow during the event
was to the south-southwest and the average hydraulic gradient was 0.024 ft/ft.
4.1 Groundwater -Sampling Methodology
Duncklee & Dunham collected groundwater samples from 12 of the 14 monitoring wells during the May
2014 sampling event. Monitoring wells K65W6D and K65W7C were dry during this event.
Duncklee & Dunham purged the wells and collected samples with a submersible, electric, PVC pump
with new, disposable polyethylene tubing from the wells greater than 35 feet in depth, and used a
peristaltic pump with new tubing for the wells less than 35 feet in depth. We collected the groundwater
samples using low -flow sampling techniques. During the sampling process, we recorded field
measurements for dissolved oxygen (DO), oxidation-reduction potential (ORP), pH, temperature,
turbidity, and electrical conductivity (Table 2). The casing to K65W6A is bent approximately two feet
below land surface and a submersible pump cannot advance past the damaged casing. Therefore, we
purged three well volumes and collected samples from K65W6A using a new, disposable, polyethylene
bailer.
Duncklee &Dunham discharged the groundwater samples directly into labeled laboratory -provided
containers, recorded the samples on a chain -of -custody form, and transported the containers to Pace in an
insulated cooler filled with ice. Pace tested the samples for nitrate according to EPA Method 353.2 and
ammonia according to EPA Method 350.1. The laboratory analytical reports and chain -of -custody
records are in Appendix B.
4.2 Results from Sampling Event
Nitrate isoconcentration maps for the shallow and deep well results are presented on Figures 6 and 7,
respectively. The test results are summarized on Table 3 and graphs of the nitrate and ammonia trends
over time are in Appendix C.
4.2.1 Nitrate Results and Trends
We observed the following with respect to the nitrate results.
• The nitrate concentrations remained within historical concentration ranges in the samples collected
from saprolite monitoring wells K65W6A, -6B, -6M, -6N, -7D and -7J. Samples from K65W6A, -
6B, -6N, and -7J exhibited nitrate at concentrations that exceed the North Carolina groundwater
quality standard (2L standard) of 10 mg/L.
• Nitrate concentrations in the samples collected from the two saprolite plume wells at the southern
extent of the plume, K65W7F and K65W7G, increased since the last sampling event to
concentrations that exceed the 2L standard. The nitrate concentration in the sample from K65W7G
increased to 118 mg/L, the highest concentration detected in samples from this well.

• The nitrate concentration in the sample from bedrock monitoring well K65W6E, located near former
Pond B, was consistent with the previous event. The overall nitrate concentrations continue to trend
upward in the samples from this well.
• Samples from the bedrock wells K65W7K and K65W7L, located in the core of the plume, exhibited
nitrate at concentrations that exceeded the 2L standard, but remain consistent with levels detected
since April 2008.
• Samples from bedrock delineation well K65W7H, at the southern extent of the plume, have not
exhibited nitrate at concentrations that exceed the 2L standard since the well was constructed in 2008.
4.2.2 Ammonia Results and Trends .
We observed the following with respect to the ammonia results.
• The samples from saprolite wells K65W7F, -7G, and -7J.exhibited ammonia at concentrations that
exceed the 2L standard of 1.5 mg/L. The laboratory detected ammonia at a concentration that
exceeds the 2L standard for the first time in the sample from K65W7F and the concentration in the
sample from K65W7G was the highest concentration detected in samples from this well. Ammonia
concentrations in samples from K65W7J have exceeded the 2L standard since April 2009.
• The samples from the bedrock wells located in the core of the plume, K65W7K and K65W7L,
exhibited ammonia at concentrations that exceed the 2L standard. The concentrations in the samples
from both of these wells are consistent with previous data.
• The samples from down -gradient plume delineation bedrock well K65W7H, in the southwestern
portion of the site, have not exhibited ammonia since the well was constructed in 2008.
5 Recommendations
Based on the information presented above, Duncklee & Dunham recommends the following:
• Continue to operate the groundwater -treatment system in accordance with the CAP and NPDES
permit between November 2014 and April 2015.
• Conduct annual monitoring of the monitoring wells in May 2015.
• Conduct an analysis of the effectiveness of the current remediation strategy and other treatment
options, and review this analysis in the next monitoring report.
