Dear Ms. Shrestha:
ATC Associates of North Carolina, P.C. (ATC), on behalf of Safety-Kleen Systems, Inc. (S-K),
has prepared this report to document post -injection groundwater sampling performed at the above
referenced site. The sampling was performed at the request of the North Carolina Division of
Water Resources (NCDWR) in an email dated December 5, 2016.
Injection of sodium persulfate and hydrogen peroxide was performed for remediation of
groundwater impacted by volatile organic compounds (VOCs) at the site in 2011 and 2012. The
injection was performed in accordance with Injection Permit WI0300181 issued by the NCDWR.
Post -injection monitoring performed through 2016 indicated that the injection was successful in
reducing concentrations of VOCs to below Title 15A NCAC 2L .0202 Groundwater Standards (2L
Standards). Groundwater samples were monitored for sulfate during five post -injection sampling
events. The results of the latest sulfate analyses in September 2013 indicated concentrations of
sulfate above pre -injection levels and the 2L Standard in monitoring wells MW-2, MW-4, and
MW-5. NCDWR issued an email dated December 5, 2016, indicating that the permit cannot be
closed out until sulfate concentrations in these wells are reduced to pre -injection levels or the 2L
Standard, whichever is greater. In response to this e-mail, ATC performed a sampling event in
December 2016.
On December 20, 2016, ATC collected groundwater samples from monitoring wells MW-2, MW-
4, and MW-5. Monitoring well locations are shown on the attached Figure 1. Groundwater
samples were collected using low -flow sampling protocol. A YSI water quality meter and flow
through cell were used to monitor temperature, conductivity, dissolved oxygen, pH, oxygen-

reduction potential, and turbidity during purging. Samples were collected after the water quality
parameters stabilized between readings. Samples were delivered to Pace Analytical Services, LLC
(Pace) under chain -of -custody protocol for analysis of sulfate by EPA Method 300.0. The
laboratory analytical report is included inAppend&A. Field parameters and sulfate concentrations
are summarized in Table 1.
The results of the laboratory analyses indicated sulfate concentrations that were substantially
reduced in comparison to the prior 2013 sampling event. Per NCDWR guidance, the permit can
be closed out when sulfate concentrations reduce to below pre -injection levels or the 21, Standard,
whichever is greater. Pre -injection sulfate concentrations measured in December 2011 ranged
from 8.8 to 37 milligrams per liter (mg/L), while the 2L Standard for sulfate is 250 mg/L. Based
on these concentrations, the goal of the sampling was to evaluate whether sulfate concentrations
have reduced to below the greater value of 250 mg/L. The results of the December 2016 sampling
event indicated sulfate concentrations remain above the 21, Standard in wells MW-2 and MW-5,
although by a fairly small margin (359 to 369 mg/L versus 21, Standard of 250 mg/L). Sulfate was
not detected at a concentration above the 2L Standard in well MW-4 (144 mg/L versus 2L Standard
of 250 mg/L).
ATC proposes to perform another sampling event in March 2017 to monitor sulfate concentrations
in wells MW-2 and MW-5. Recommendations will be made for further monitoring or corrective
action based on the results of this sampling event. No further sampling is proposed for well MW-
4 since the December 2016 sampling indicated no exceedences of the 2L Standard.
ATC and S-K appreciate the NCDEQ's assistance in this matter. If you have questions or require
additional information, please contact Robert Schoepke (Safety-Kleen Project Manager) at (847) 468-
6733 or Genna Olson (ATC Project Manager) at [phone].

Dear Ms. Shrestha:
ATC Associates of North Carolina, P.C. (ATC), on behalf of Safety-Kleen Systems, Inc. (S-K),
has prepared this report to document post -injection groundwater sampling performed at the above
referenced site. This report details background information and the results of a sampling event
performed on March 30, 2017.
1.0 Background Information
Injection of sodium persulfate and hydrogen peroxide was performed for remediation of
groundwater impacted by volatile organic compounds (VOCs) at the site in 2011 and 2012. The
injection was performed in accordance with Injection Permit WI0300181 issued by the NCDWR.
Post -injection monitoring performed through 2016 indicated that the injection was successful in
reducing concentrations of VOCs to below Title 15A NCAC 2L .0202 Groundwater Standards (2L
Standards). Groundwater samples were initially monitored for sulfate during five post -injection
sampling events between June 2012 and September 2013. The results of the sulfate analyses in
September 2013 indicated concentrations of sulfate above pre -injection levels and the 2L Standard
in monitoring wells MW-2, MW-4, and MW-5. NCDWR issued an email dated December 5,
2016, indicating that the permit cannot be closed out until sulfate concentrations in these wells are
reduced to pre -injection levels or the 2L Standard, whichever is greater. Note that the 2L Standard
for sulfate is higher than pre -injection levels; therefore, the 2L Standard is the goal for closure of
the permit. The current 2L Standard for sulfate is 250 milligrams per liter (mg/L).

In response to the NCDWR's December 5, 2016 e-mail, ATC performed,a sampling event at the
site on December 20, 2016. Groundwater samples were collected from monitoring wells MW-2,
MW-4, and MW-5 for analysis of sulfate. The results of the sampling event indicated sulfate
concentrations remain above.the 2L Standard in wells MW-2 and MW-5, although by a fairly small
margin (359 to 369 mg/L versus 2L Standard of 250 mg/L). Sulfate was not detected at a
concentration above the 2L Standard in well MW-4 (144 mg/L versus 2L Standard of 250 mg/L).
The results of the sampling event were documented in a.Post-Injection Groundwater: Sampling
Results report dated January 24, 2017. The report recommended completion of another sampling
event for wells MW-2 and MW75 in March 2017. .
The NCDWR responded to the January 2017 report with an email dated February 9, 2017. The
email indicated that NCDWR would require two sampling events showing no exceedences of 2L:
Standards in order to approve discontinuation of monitoring.. As such, the email requested
collection of samples from well MW-4 in addition to wells MW-2 and MW-5.. This report
documents completion of the subsequent sampling event in March 2017.
2.0 Groundwater Sampling
On March 30, 2017, ATC collected groundwater samples from monitoring wells MW-2; MW-4,
and MW-5. Monitoring well locations are shown on the attached Figure 1. Groundwater samples
were collected using low -flow sampling protocol. A YSI water quality meter and flow through cell
were used to monitor . temperature, conductivity, dissolved oxygen, pH, oxygen -reduction
potential, and turbidity during purging. Samples were collected after the water quality parameters
stabilized between readings. Samples were delivered to Pace Analytical Services, LLC (Pace)
under chain -of -custody protocol for analysis of sulfate by EPA Method 300.0.
The results of the laboratory analyses indicated sulfate concentrations remain above the 2L
Standard in well MW-5, although by a fairly -small margin (381 mg/L versus 2L Standard of 250
mg/L). Sulfate: was not detected at concentrations above the 2L Standard in wells MW-2 and MW-
: 4 (149 and,159 mg/L, respectively, versus 2L Standard of 250 mg/L). The laboratory analytical
report is included in Appendix A. Field parameters and sulfate concentrations are summarized in
Table 1.
3.0 Conclusions and Recommendations-
ATC has completed a groundwater sampling event at the S-K site in Charlotte, North Carolina, in
order to monitor post -injection concentrations of sulfate. The scope of the sampling was limited
'to three wells which historically contained concentrations of sulfate above the 2L Standard. The
results of the sampling and recommendations for each monitoring well are summarized below:
• Sampling of monitoring well MW-2 in March. 2017 indicated no exceedences of the 2L
Standard for sulfate. This is the first sampling event indicating concentrations below the
2L Standard. ATC proposes to perform an additional sampling event for well MW-2.in
September 2017. -If the results indicate no exceedences of the 2L Standard, no further
sampling will be proposed for this well.

• Sampling of monitoring well MW-4 in December 2016 and March 2017 indicated no
exceedences of the 2L Standard for sulfate. Since no exceedences have been identified for
two consecutive sampling events, ATC proposes to discontinue sampling of this well.
• Sampling of monitoring well MW-5 indicated exceedences of the 2L Standard for sulfate
in both December 2016 and March 2017. ATC proposes to perform an additional sampling
event for well MW-5 in September 2017. Recommendations will be made for further
monitoring or corrective action based on the results of this sampling event.
ATC and S-K appreciate the NCDEQ's assistance in this matter. If you have questions or require
additional information, please contact Robert Schoepke (Safety-Kleen Project Manager) at (847) 468-

Hart & Hickman, PC (H&H), on behalf of Safety-Kleen Systems, Inc. (S-K), has prepared this
report to document post -injection groundwater sampling performed at the above referenced site.
This report details background information and the results of a sampling event performed on
March 26, 2018.
1.0 Background Information
Injection of sodium persulfate and hydrogen peroxide was performed for remediation of
groundwater impacted by volatile organic compounds (VOCs) at the site in 2011 and 2012. The
injection was performed in accordance with Injection Permit WI0300181 issued by the North
Carolina Division of Water Resources (NCDWR). Post -injection monitoring performed through
2016 indicated that the injection was successful in reducing concentrations of VOCs to below Title
15A NCAC 2L .0202 Groundwater Standards (2L Standards). Groundwater samples were initially

monitored for sulfate during five post -injection sampling events between June 2012 and September
2013. The results of the .sulfate analyses in. September 2013 indicated concentrations of sulfate
above re injection levels :and the 2L Standard in monitoring wells. MW-2 MW-4 and.MW=5.
p _ :J . g ,
NCDWR issued an ernail dated December '5, 2016, indicating that the permit cannot be closed out
until sulfate: concentrations in these wells are reduced: to pre -injection levels or the 2L Standard,
whichever is greater. -Note that the, 2L Standard for sulfate.is:higher than. pre -injection levels-
therefore., the. 2L Standard is the goal for closure of th.e permit The current 2L Standard. for.sulfate .
is 250 milligrams per liter_ m /l,
... ....... .. .......
In response to the NCDWR'.s December 5, 20:16. a=mail, a sampling -event was performed at the
site on December 20,:2016. Groundwater samples were collected from monitoring wells MW-2,
. .....
MW-4, and: MW-5 for analys s:of sulfate. The results of the sampling event indicated sulfate
concentrations above .the 2L Standard in .wells MW-2 and MW-5. Sulfate was not detected at .a
concentration, above the 2L. Standard in well-MWA, The results of.the. sampling event .were
documented. in a Post -Injection Groundwater Sam ii Results re orf dated: January 24. 20:17. The
�.. p g P. ;
report recommended: completion of another sampling event for wells MW-2 and MW-5 in March
2017.
The NCDWR responded to the: January 20 1'7: reporC with an email dated February 9; 2017. The
email indicated that NC DWR would require: two sampling events showing no exceedances of 2L
Standards .in order to approve . discontinuation of .monitoring. As such, the email.. requested
i
collection: of samples from .well MW-4 in addition to. wells MW-2 and :MW-5. A groundwater
sampling event was subsequently performed for wells MW-2, MW-4, and MW-5 on March 30,
i
2017. The. results of the sampling event indicated -sulfate concentrations: above the 2L Standard. in
well MW-5. Sulfate was not detected at concentrations above the 2L Standard in wells MW-2 and ..
MW-4. The results of the sampling event were documented in:a Post -Injection Groundwater
Sampling Results report dated April- 28;. 2017. The report , recommended completion of an
i
additional samplingevent.for wells MW-2 and MW-5 in September 2017: Since sulfate was not
detected above the 2L..Standard for two..consecutive sampling events in well MW-4, the report
recommended discontinuation of sampling for this well.

.:
September 2017. The.. results of the .sampling event. were ..documented : in: a .Post -Injection
Groundwater Sampling Results report dated November 13, 2017. The.results indicated that sulfate
concentrations in well MW-2 were below the 2L Standard,, whine those in well. NIW-5 remained
above the 2L Standard. Since sulfate was not detected above the 2L Standard for two consecutive
sampling events in well MW=2; the report recommended discontinuation of sampling for this well.
However, since sulfate concentrationsin well MW-5_ remained above the 2L: Standard, _the .report .
recommended sampling of well MW-5 in March 2018. The results, of the:March 2018 sampling
event are documented in. this report.
2.0 Groundwater Sampling
_.. .._.
On- March 26; 2018; H&H collected groundwater, samples from monitoring well MW:5:
Monitoring. well locations.. are.. shown on the attached Figure I. The. groundwater sample.. was
collected using: low -flow sampling protocol. A.YSI-water quality meter and flow through.cell were
used to monitor temperature, conductivity, dissolved oxygen, pH; oxygen -reduction potential, and
turbidity, during purging. The:sample was collected after the water quality parameters stabilized
..between readings. The. sample was delivered to Test American Laboratories' Inc. under chain -of- .
custody protocol for analysis of,sulfate by EPA Method 9056A.
The' results of the -laboratory.. analyses indicated. sulfate concentrations .remain above the _2L -
Standard in :well MW-5, although :by a fairly small margin (315 mg/L versus 2L Standard of 250
mg/L). The detected sulfate concentration was reduced in comparison to the prior sampling event.
The laboratory: analytical report is. included in Appendix A. (Note: that the laboratory report also
..documents soil sampling that is not discussed in this report. because it is not pertinent to the ..
NCDWR groundwater injection permit; the soil data is being submitted to the NC Division of
Waste Management [NCDWM] in a separate report.) Field parameters and sulfate concentrations
are summarized in Table 1..

order to monitor post -injection concentrations of sulfate. The scope of the sampling was limited to
well MW-5 because the remaining site wells have indicated no exceedances of the 21, Standard
for sulfate for at least two consecutive sampling events. The results of the sampling event indicated
sulfate at a concentration of 315 mg/L in well MW-15. The concentration is reduced in comparison
to the prior sampling event, but still exceeds the 2L Standard of 250 mg/L.
VOC and semi-VOC (SVOC) impacts at the site are regulated by the NCDWM Hazardous Waste
Section. H&H is currently pursuing risk -based closure for the VOC and SVOC impacts under
North Carolina General Statute 130A-310.65 to 310.77. As part of the risk -based closure, a
groundwater use restriction will likely be implemented for the site property. If a groundwater use
restriction is implemented, H&H will request that the NCDWR close out the injection permit
despite sulfate concentrations in exceedance of the 21, Standard. Based on work performed at
another NCDWR permitted site, H&H understands that this may be allowed under Title 15A
NCAC 21, (21, Rules) Subparagraph .0106(k), which indicates that a responsible party may request
approval of a plan that does not require groundwater remediation to the 21, Standards. H&H plans
to contact NCDWR personnel to discuss requirements for pursuing permit closure under this rule.
H&H and S-K appreciate the NCDEQ's assistance in this matter. If you have questions or require
additional information, please contact Robert Schoepke (Safety-Kleen Project Manager) at (847) 468-
6733 or Genna Olson (H&H Project Manager) at [phone].
Sincerely,

Method 8270D: The.continuing calibration verification, (CCV) analyzed in batch. 460=505004 was outside the method criteria for the
following analytes: bis ,(2-chloroisopropyl) ether and Di-n-octyl phthalate. A CCV standard at or below the reporting limit (RL) was analyzed���
With the affected samples:and found to be acceptable.: As indicated in.the reference method, :sample analysis may proceed; however, any
detection for the affected analyte(s) is:considered estimated.
Method 8270D: The continuing calibration verification (CCV) associated with. batch 490-505511 recovered above the :upper control limit for
2,2'-oxybis[1-chloroprbparie]:N-Nitrosodimethylamine, N-Nitrosodi-n-propylamine, 4-Nitrophenol, Bis(27chloroethyl)ether and Phenol. The
samples associated with this CCV were non -detects for;the affected analytes; therefore, -the data have been reported. The following
samples are impacted: B-6C (10') (490A48970-2) and (CCVIS:490-505511/3).
Method 8270D: The continuing calibration verification. (CCV) associated with, batch 490-506051 recovered above the upper control limit for
3,3'=Dichlorobenzidine and Bis(2-ethylhexyl) phthalate..The samples associated with this-CCV were no for the affected analytes;
therefore, the data have been reported.- The following samples.are impacted: B-6C.(5'):(490-148970-1), B-6C (10') (490-148970-2) and
(CCVIS 490-506051/3)...
Method 8270D: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated:with
preparation batch 490-505891 and analytical batch 490-506051:
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Method 9056A: The matrix spike / matrix spike duplicate:(MS/MSD) recoveries for analytical batch 490-504897 were outside control limits. .
Sample matrix interference•and/or non -homogeneity are suspected :because the associated:laboratory control sample (LCS) recovery
was within acceptance limits.
Method 9056A4 Due to the high concentration of Sulfate the matrix spike / matrix spike duplicate (MS/MSD) for analytical batch 490-505023
could not be evaluated for,accuracy and precision.. The associated laboratory_controlsample (LCS) met acceptance criteria.
Method 9056A: The following sample was diluted due to the nature of the sariiple matrix: MW-5 (490-148970-3). Elevated reporting limits

Dear Ms. Shrestha:

NOV 17 2017
Water Quality Regional
Operations Section
Hart & Hickman, PC (H&H), on behalf of Safety-Kleen Systems, Inc. (S-K), has prepared this
report to document post -injection groundwater sampling performed at the above referenced site.
This report details background information and the results of a sampling event performed on
September 26, 2017.
1.0 Background Information
Injection of sodium persulfate and hydrogen peroxide was performed for remediation of
groundwater impacted by volatile organic compounds (VOCs) at the site in 2011 and 2012. The
injection was performed in accordance with Injection Permit WI0300181 issued by the North
Carolina Division of Water Resources (NCDWR). Post -injection monitoring performed- through
2016 indicated that the injection was successful in reducing concentrations of VOCs to below Title
15A NCAC 2L _.0202 Groundwater Standards (21, Standards). Groundwater samples were initially

monitored for sulfate during five post -injection sampling events between June 2012 and September
2013. The results of the sulfate analyses in September 2013 indicated concentrations of sulfate
above pre -injection levels and the 2L Standard in monitoring wells MW-2, MW-4, and MW75.
NCDWR issued an email dated December 5, 2016, indicating that the permit cannot be closed -out
until sulfate concentrations in these wells are reduced to pre -injection levels or the 2L Standard,
whichever is greater. Note that the 2L Standard for sulfate is higher than pre -injection levels;
therefore, the 2L Standard is the goal for closure of the permit. The current 2L Standard for sulfate
is 250 milligrams per liter (mg/L).
In response to the NCDWR's December 5, 2016 e-mail, a sampling event was performed at the
site on December 20, 2016. Groundwater samples were collected from monitoring wells MW-2;
MW-4, and MW-5 for analysis of sulfate: The results of the sampling event indicated sulfate
concentrations above the 2L Standard in wells MW-2 and MW-5. Sulfate was not detected at a -
concentration above the 2L Standard in well MW-4. The results of the sampling event were
documented in a Post -Injection Groundwater Sampling Results report dated January 24, 2017. The
report recommended completion of another sampling event for wells MW-2 and MW-5 in March
2017.
The NCDWR responded to the January 2017 report with an email dated February 9, 2017. The
email indicated that NCDWR would- require two sampling events showing no exceedences of 2L
Standards in order to approve discontinuation of monitoring. As such, the email requested
collection of samples from well MW-4 in addition to wells MW-2 and MW-5. A groundwater
sampling event was subsequently performed for wells MW-2, MW-4, and MW-5 on March 30,
2011. The results of the sampling event indicated sulfate concentrations above the 2L Standard in
well MW-5. Sulfate was not detected at concentrations above the 2L Standard in wells MW-2 and
MW-4. The results of the sampling event were documented in a Post -Injection Groundwater
Sampling Results report dated April 28, 2017. The report recommended completion of an
additional : sampling event for wells MW-2 and MW-5 in September 2017. The :results of the
subsequent September 2017 sampling event are documented in this report. Since sulfate was not

detected above the 2L Standard for two. consecutive sampling events in well MW-4, the report
recommended discontinuation of sampling for this well.
2.0 Groundwater Sampling
On September 26, 2017, H&H collected.groundwater samples from monitoring wells MW-2 and
MW-5. Monitoring well locations are shown, on the attached Figure 1. Groundwater. samples were
collected using low -flow sampling protocol. A YSI water quality meter and flow through cell were
used to monitor temperature, conductivity, dissolved oxygen, pH, oxygen -reduction potential, and
turbidity during purging. Samples were collected after the water quality parameters stabilized
between readings. Samples were delivered to Pace Analytical Services, LLC (Pace) under chain -
of -custody protocol for analysis of sulfate by EPA Method 9056A.
The results of the laboratory analyses indicated sulfate concentrations remain above the 21,
Standard in well MW-5, although by a fairly small margin (330 mg/L versus 2L Standard of 250
mg/L). Sulfate was not detected at a concentration above the 2L Standard in well MW-2 (140 mg/L
versus 2L Standard of 250 mg/L). The laboratory analytical report is included inAppend&A. Field
parameters and sulfate concentrations are summarized in Table 1.
3.0 Conclusions and Recommendations
H&H has completed a groundwater sampling event at the S-K site in Charlotte, North Carolina, in
order to monitor post -injection concentrations of sulfate. The scope of the sampling was limited to
two wells which historically contained concentrations of sulfate above the 2L Standard. The results
of the sampling and recommendations for each monitoring well are summarized below:
• Sampling of monitoring well MW-2 in September 2017 indicated no exceedences of the
2L Standard for sulfate. The results of the prior sampling event in March 2017 also
indicated no exceedences .of the 2L Standard for sulfate. Since no exceedences have been

detected for two consecutive sampling events, H&H proposes to discontinue sampling of
this well.
• Sampling of monitoring well MW-5 in September 2017 indicated exceedences of the 2L
Standard for sulfate. The results of prior sampling events for this well also indicated
exceedences of the 21, Standard for sulfate. A review of concentrations over time indicates
a reducing trend. H&H proposes to perform an additional sampling event for well MW-5
in March 2018. Recommendations will be made for further monitoring or corrective action
based on the results of this sampling event.
H&H and S-K appreciate the NCDEQ's assistance in this matter. If you have questions or require
additional information, please contact Robert Schoepke (Safety-Kleen Project Manager) at (847) 468-
