1.0 INTRODUCTION

1.1 Site Information

The Rockingham County Solid Waste Management Facility (the Facility) is owned and operated
by Rockingham County and is operating under North Carolina Solid Waste Permit Nos. 79-01
and 79-04. The Facility is located off Shuff Road, west of the town of Wentworth in central
Rockingham County, North Carolina. The property boundary is indicated on an excerpt from the
7.5 minute USGS topographic map for Bethany and Southwest Eden, North Carolina (Figure 1).
The property is surrounded by rural wooded areas and farmland.

The Rockingham County Solid Waste Management Facility consists of three waste disposal
areas. Areas I, II, III, and IV (I-IV) and Area V are closed unlined municipal solid waste (MSW)
landfill areas under Permit No. 79-01. The active Subtitle D MSW landfill is covered under
Permit No. 79-04.

1.2 Site Geology
The Facility is located in the Piedmont physiographic province. Geologically, the site is located
in the Milton Belt, which contains schist and gneiss of amphibolite facies, with minor areas of
granitic intrusive rock. Regional geology is shown on the Geologic Map of Region G, North
Carolina (Carpenter, 1982). Carpenter mapped bedrock in the vicinity of the site as the mgs unit,
which contains biotite gneiss and schist, locally interlayered with hornblende gneiss and schist
and felsic gneiss. Map patterns and outcrop information for the Milton Belt indicate that the
metamorphic rock is broadly folded, with foliation of moderate to gentle dips. Strikes for
outcrops are variable, owing to the generally flat-lying nature of the geologic structure; the
regional strike is to the east-northeast (Carpenter, 1982).

Triassic diabase dikes shown in the region, mapped on the basis of aeromagnetic surveys and
occasional outcrop, have consistent strikes of approximately 10 to 20 degrees west of north.
Quaternary alluvium is mapped in the larger drainages in the site vicinity, including Jacob’s
Creek and its tributaries.

1.3 Regulatory Status

The Closed Landfill Areas I-IV were closed prior to implementation of RCRA Subtitle D
requirements. The landfill is currently monitoring groundwater in accordance with criteria set
forth in Rule .0500 of the North Carolina Solid Waste Management Regulations (NCSWMR) for
municipal solid waste landfills (MSWLF) closed prior to October 9, 1993.

The Closed Landfill Area V groundwater monitoring is completed in accordance with NCSWMR
§ 1633 (Detection Monitoring Program) and NCSWMR § 1634 (Assessment Monitoring
Program).

____________________________________________________________________________________________ Second Semiannual Water Quality Monitoring Report of 2015 Joyce Engineering
Rockingham County Solid Waste Management Facility, Permit Nos. 79-01 & 79-04 November 2015

The Subtitle D Landfill groundwater and surface water monitoring is completed in accordance
with NCSWMR § 1633 (groundwater) and § 0602 (surface water). Statistical analysis of the
laboratory data has been prepared in accordance with the required compliance demonstration of
NCSWMR .1632(g) and (h).

2.0 FACILITY MONITORING PROGRAMS

Groundwater monitoring programs for each of the landfills, surface water, and leachate storage
system are discussed in the following sections and locations are shown on Drawing 1.

2.1 Closed Landfill Areas I-IV Monitoring Program
The Closed Landfill Areas I-IV was closed prior to implementation of RCRA Subtitle D
requirements. Groundwater monitoring at the facility is completed as required by the
NCSWMR. Groundwater samples are collected semiannually and analyzed for all constituents
listed in NCSWMR Appendix I.

The groundwater monitoring network for the Closed Landfill Areas I-IV originally consisted of
one upgradient well (MW-4A) and four downgradient wells (MW-3A, MW-6, MW-7, and
MW-8). In a letter from the Solid Waste Section (SWS) dated July 28, 2000, which was received
prior to the July 2000 event, MW-3A and MW-8 were approved for removal from the sampling
requirements for detection monitoring, but continue to be monitored for water levels only. In the
same letter, two additional pairs of wells, MW-12S/MW-12D and MW-13S/MW-13D were
added to the compliance monitoring system and sampled for the first time during the June 2001
event. Well pair MW-13S/MW-13D is sampled semiannually, while the pair MW-12S/MW-12D
is sampled bi-annually (beginning in June 2001), as directed in the same correspondence.

MW-13S - Compliance Detection 17.00 Saprolite (Estimated) MW-13D - Compliance Detection 77.00 Bedrock (Estimated)

2.2 Closed Landfill Area V Monitoring Program

Groundwater monitoring for Closed Landfill Area V is completed in accordance with NCSWMR
§ 1633 and § 1634 (Detection and Assessment Monitoring Programs) and the Water Quality
Monitoring Plan for the facility. Groundwater samples are collected semiannually and analyzed
for all constituents listed in NCSWMR Appendix I list, except for MW-9 and MW-11, which are

sampled for the NC Appendix I plus additional detected Appendix II constituents during both
semiannual events.

MW-5 entered assessment monitoring and was sampled for the NC Appendix II list of
constituents starting with the second semiannual groundwater monitoring event of 2010 through
the first semiannual groundwater monitoring event of 2012. Modifications to the monitoring
program were made per correspondence received by the County from the SWS dated October 4,
2010. Following the first semiannual 2012 groundwater monitoring event, MW-5 will remain in
assessment monitoring but will monitor for a reduced list of parameters consisting of only NC
Appendix I metals and NC Appendix I volatiles. The groundwater monitoring network at the
Closed Landfill Area V consists of one upgradient/background well (MW-1A) and three
downgradient wells (MW-5, MW-9, and MW-11). Monitoring well MW-2A, which was
sampled during previous events, was removed from the list of sampling locations based on the
SWS letter dated July 28, 2000. MW-2A continues to be monitored for water levels only.

Rockingham County received a letter from the SWS dated January 8, 2004, instructing the
County to proceed with an assessment of corrective measures at the Closed Area V Landfill. The
County submitted an Update on Groundwater Assessment Activities to the SWS on May 6, 2005.
In a letter dated October 4, 2010, the SWS granted conditional approval for the removal of
NES-1 from the sampling requirements of semiannual monitoring, but NES-1 will continue to be
monitored for water levels only.

2.4 Surface Water Monitoring Program

Surface water monitoring at the Facility is completed in accordance with the NCSWMR and the
approved Water Quality Monitoring Plan. Surface water samples are collected semiannually and
analyzed for the constituents listed in NCSWMR Appendix I. The surface water monitoring
network includes one upstream surface water sampling point (SMP-3), three downstream surface
water monitoring points (SMP-1, SMP-2, and SMP-4), and one surface water monitoring point
(SMP-5) located at the end of the underdrain from Phase 3 before entering the sediment trap.

and the laboratory results are provided in Appendix 2. The following constituents are required for
laboratory leachate analysis:

 North Carolina Appendix I Metals
 North Carolina Appendix I 8260 Volatiles
 Total Suspended Solids (TSS)
 Biochemical Oxygen Demand (BOD)
 Nitrogen, Nitrate
 Total Phosphorus
 Chemical Oxygen Demand (COD)
 Sulfate

3.0 SECOND SEMIANNUAL SAMPLING EVENT OF 2015

3.1 Field Work

On September 28-30, 2015, personnel from Joyce Engineering (JOYCE) visited the Facility to
obtain water levels to the nearest 0.01 foot, purge, and sample monitoring wells at the Closed
Areas I-IV, Closed Area V, and Subtitle D Landfills. Four surface water monitoring points
(SMP-5 was dry) and one leachate monitoring point was also sampled during the September
2015 event. In addition, at monitoring wells that are not part of the compliance network,
depth-to-water measurements were obtained to the nearest 0.01 foot using an electronic water
level indicator.

Due to extreme flooding during the September 2015 sampling event Area I-IV monitoring well
MW-12S and MW-12D were unable to be accessed and were not sampled. Additionally,
Subtitle-D landfill wells MW-15, MW-17S, and MW-20S were dry and were not sampled.

Monitoring wells were purged and sampled using disposable bailers or a 12 volt plastic pump
during the September 2015 event. Measurements of temperature, pH, specific conductivity, and
turbidity were recorded prior to purging, after each purge volume, and during sampling. Prior to
sampling, laboratory-supplied containers were prepared with the following information:

 Monitoring well number (completed by field personnel),
 Date and time of sample collection (completed by field personnel),
 Initials of sampling personnel (completed by field personnel),
 Project name and number (completed by the laboratory),
 Chemical preservative (completed by the laboratory); and
 Requested chemical analysis (completed by the laboratory).

During the sampling event, groundwater samples from each monitoring well were collected
directly from the bailers and transferred to the provided laboratory containers either immediately
after purging or within 24 hours of the final purge volume. Immediately after collection, the
samples were placed in a laboratory provided cooler and chilled on ice.

Surface water samples were collected directly from stream flow, by lowering the prepared sample
containers into the stream. Care was taken not to overflow the sample containers (which could
lead to preservative loss) and avoid sample-induced turbidity. At the time of sampling, surface
water was also measured for temperature, pH, specific conductivity, and turbidity. After
collection, the samples were placed in a laboratory provided cooler and chilled on ice.

Leachate samples were collected from a leachate lagoon. Prepared sampling containers were
filled, placed in a cooler, and chilled on ice. At the time of sampling, leachate was measured for
temperature, pH, specific conductivity, and turbidity.

3.2 Laboratory Analysis and JOYCE Quality Control

The September 2015, groundwater, surface water, and leachate samples were submitted to Pace
Analytical Services, Inc. of Huntersville, North Carolina under chain-of-custody control for
analysis. JOYCE requested a Level II data report for the final laboratory reports. The samples
were received by the laboratory on September 30, 2015, in good condition, properly preserved,
and within analysis hold times.

In addition to samples collected for compliance monitoring at the facility, a Field Blank was
collected by JOYCE personnel as part of the September 2015 sampling. Also, a Trip Blank was
prepared by the laboratory to accompany the volatile sampling containers during shipment. The
Field Blank was analyzed for North Carolina Appendix I constituents plus mercury, tin and
dichlorodifluoromethane while the Trip Blank was analyzed for NCSWMR Appendix I volatile
organics plus dichlorodifluoromethane only.

Upon receipt of complete laboratory data packages on October 13, 2015, the data was reviewed
by JOYCE personnel for the following:

 General typographical errors;
 Correct analyses performed and within method specified hold times;
 Biased data results based on Surrogate Recoveries, Matrix Spike, Matrix Spike Duplicate,
and Laboratory Control Samples;
 Blank qualified data (B-flags);
 Detections above the North Carolina SWSLs, groundwater and surface water standards; and
 Detections that are above historical levels.

4.0 HYDROGEOLOGY

Depth to groundwater was measured in each monitoring well at the site prior to purging. The
groundwater elevation at each well was calculated relative to the surveyed measuring point (top
of casing) for each monitoring well. Tables 1A, 1B, and 1C summarize the groundwater
elevations.

Groundwater elevation contours were interpreted from the September 2015 water level
measurements to create the potentiometric surface map. Groundwater flow paths at the site
converge on the creeks that bisect the site and border it to the west-southwest. Groundwater flow
beneath the Closed Area I-IV and Area V Landfills is predominantly to the south. Flow beneath
the Subtitle D Area Landfill is radial from the southeast to the north, northwest, and west. The
potentiometric surface contours for groundwater are shown on Drawing 1.

Horizontal groundwater gradients were estimated based on the September 2015 groundwater
levels. Gradients were estimated from groundwater flow arrow segments that intersect
potentiometric surface contours. These gradients are summarized in Table 2. The horizontal
gradients were calculated as approximately 0.06 to 0.07 ft/ft for Closed Areas I-IV,
approximately 0.06 ft/ft for Closed Area V, and range from 0.07 to 0.11 ft/ft for the Subtitle D
area. These gradients are consistent with previous gradient estimates (CDM, 1996; JOYCE,
1998).

Average hydraulic conductivities (K) from each slug-tested well were used to estimate average
linear groundwater flow velocities. Linear groundwater flow velocities for wells screened in
saprolite were computed using the following modified Darcy equation:

V = Ki/n,

where V = average linear velocity (feet/day), K = hydraulic conductivity (ft/day), i = horizontal
hydraulic gradient, and n = effective porosity.

The linear groundwater flow velocity estimates are approximately 1.47 to 1.84 ft/day in Closed
Areas I-IV, 1.96 ft/day for the Closed Area V, and from 1.66 to 21.06 ft/day for the Subtitle D
area as shown in Table 2. These ranges are consistent with previous estimates (CDM, 1996;
JOYCE, 1998). The linear velocity equation and resulting rates make the simplified assumptions
of a homogeneous and isotropic aquifer. This equation can over-estimate velocities when
applied to heterogeneous and/or anisotropic conditions such as are believed to exist at this site.
Site boring logs record that regolith sampled at the site often exhibited the remnant foliation and
other parent rock textures. These characteristics can impart locally anisotropic groundwater flow
directions. The regolith and bedrock are hydraulically connected, but effective porosity typically
declines markedly downward into underlying fractured bedrock (Harned, 1989).

Cobalt detections above the GWPS have been addressed in the Alternate Source Demonstration
– Cobalt approved by the DENR in a letter dated May 9, 2011. Beryllium in MW-9 and MW-11
was detected above its GWPS, while arsenic in MW-17D, and cadmium in MW-19, were
detected above each respective NC 2L concentration; however, the detections were each below
the site specific calculated background concentrations (see section 5.3). Since arsenic, beryllium,
and cadmium were below the site specific calculated background values, there were no
exceedances of the GPS as defined by rule .1634.g. No other inorganic constituents were
detected above their NC 2L or GWPS.

5.1.4 Surface Water

There were no quantified detections of NC Appendix I constituents in surface water samples
during the September 2015 sampling event. The inorganic and organic analytical results from the

September 2015 monitoring event for surface water are summarized in Table 9 and field
parameters are summarized in Table 10 of this report. The results, as reported by the laboratory,
the laboratory quality assurance/quality control information, and the chains of custody are
included in Appendix 1. Based on this data, it appears the surface water in the area is not being
negatively impacted by the Closed Landfill Area 1-IV, Closed Landfill Area V, or Subtitle D
Landfill.

5.1.5 Leachate

this report. The results, as reported by the laboratory, the laboratory quality assurance/quality
control information, and the chains of custody record are included in Appendix 1.

5.2 Statistical Methods

The data were evaluated through the use of the Shapiro-Wilk Test, Parametric Prediction Limits,
Parametric Tolerance Intervals, Aitchison’s Adjustment, Non-parametric Prediction Limits, and
Poisson Prediction Limits, as appropriate. Background data, tests for normality, outliers,
Aitchison’s adjustment, tolerance interval, or prediction limits are used, as appropriate based on
the background data.

The statistical test by which downgradient data are compared to facility background data is based
upon the nature of the data and the number of data values that are less than the laboratory limit of
detection. All statistical tests are evaluated at the 0.05 level of significance, 95% confidence
level, and are conducted as one-tailed tests. Statistical background values were calculated using
data from historical semiannual sampling events at the Subtitle D landfill.

5.3 Statistical Results

Mercury and Vanadium in the Area V landfill were detected above their NC 2L and GWPS
respectively. At the Subtitle D landfill, beryllium in MW-3 and MW-11 was detected above its

GWPS, and arsenic in MW-17D, and cadmium in MW-19 were each detected above their
respective NC 2L standards. The Arsenic, beryllium, and cadmium detections were statistically
evaluated in accordance with the procedures outlined in 15A NCAC 13B.1632 (g) and (h) to
determine if the reported concentration exceeded the facility background concentrations.

beryllium, and cadmium were not identified as statistically significant and are representative of
historical background concentrations.

6.0 CONCLUSIONS

Based on the analytical results from the September 2015 sampling event, Rockingham County
will continue to monitor the uppermost aquifer beneath the Area I-IV landfills in accordance with
the requirements as outlined in Title 15A NCAC 13B.0500 while the Area V and Subtitle D
landfills will continued to be monitored as outlined in Title 15A NCAC 13B .1633 & .1634. The
next semiannual sampling event is tentatively scheduled for April 2015.

Three VOCs, benzene, 1,2-dichloroethane (DCA) and vinyl chloride were historically detected in
MW-19. Benzene and DCA were detected in MW-19 for the first time in October 2011, after
five years of sampling from that well. Vinyl chloride was first detected in April, 2012. Since
first being detected, the concentration of benzene in MW-19 peaked in the December 2011
sampling event, and in four subsequent sampling events has steadily declined. In the April 2013
event, the concentration of benzene in MW-19 dropped to below the 2L standard. The
concentration of DCA peaked in April 2012 and has declined in the last two events, to a level
below the standard. Vinyl chloride first appeared in April 2012 and has declined in the two
subsequent sampling events to be below its standard, so in the October 2012 sampling event,
only benzene remained above the standard at a concentration of 1.2 µg/L, as compared to the
standard of 1 µg/L. Prior to the October 2012 sampling event, MW-19 replacement well MW-
19R was installed. JOYCE believed, based on field observations that the integrity of the seal in
MW-19 may have been compromised as a result of significant erosion in the area of the well. At
the request of NCDENR, MW-19 was left in place following the installation of MW-19R, and
both wells were sampled. Benzene concentration in MW-19R, was non-detect in the April 2013
event.

On February 8, 2013, JOYCE submitted an Addendum to the April 2012 Alternate Source
Demonstration (ASD). As suggested in the April 19, 2012 ASD, the additional data submitted in
the Addendum supported the conclusion that the likely source of the VOCs was an isolated
random release rather than an ongoing release from the landfill. This is suggested by the sudden
appearance and the rapid decline in concentration since a peak at the time of first detection or
shortly thereafter. The decline suggests that there is not an ongoing source and that natural
diffusion, dispersion and biodegradation is successfully degrading the VOCs. All three detected
constituents are below the applicable standard. On March 25, 2013, in a response to the ASD
Addendum, NC DENR concurred that the appropriate action at this point was to continue to
monitor the decline for two additional sampling events (April 2013 and October 2013) before
requiring any additional response actions.

For the October 2013 event, benzene exceeded the 2L standard in both MW-19 and MW-19R, up
from both being either below detection limits or below the 2L standard in the April 2013 event.
Because this one data set represents a reversal of the prior downward trend for benzene in both
wells, JOYCE requested that the review period be extended an additional two monitoring events
(April 2014 and October 2014) before any decisions are made regarding the need to enter into
assessment monitoring.

For the September 2014 event, benzene exceeded the 2L standard in both MW-19 and MW-19R,
up from both being below the SWSL and NC 2L standard in the April 2014 event. This one data
set represented a reversal of the prior downward trend for benzene in both wells. In a phone
conversation on November 13, 2014, Joyce discussed these results with Ervin Lane of NC
DENR, and it was agreed that since the concentrations of benzene have fluctuated from just
above to below the NC 2L standard over the last few events, we could wait to see the results of
the next event (Spring 2015) before determining whether to initiate Assessment Monitoring.
Since benzene concentrations in MW-19 & MW-19R were not exceedences in the March 2015
sampling and were non-detect in the September 2015 sampling event, it is not anticipated that
Assessment Monitoring will have to be initiated.

Notes: All concentrations are in µg/L.
DL = Laboratory detection limit.
MW = Groundwater monitoring well.
QL = Quantiation limit
J = Estimated value between DL and SWSL.
B = Blank qualified detections.
ND = Not detected above laboratory reporting limit (October 1996 - June 2006). Not detected above the laboratory detection limit (December 2006 - Present).
'--- = Not Sampled and/or Not Reported.
NI = Not Installed. An NI designation indicates the well was not installed, exterior well construction not complete, not developed, or prior to background sampling.
NC 2L = North Carolina 2L Groundwater Standard.
GWPS = Groundwater Protection Standard.
Bold values are above the NC 2L Groundwater Standard or Groundwater Protection Standard (GWPS).
When the NC 2L Standard has not been established, the GWPS will substitute.
{ } = When Method Blank concentrations are higher than Trip or Field (Equipment) Blank concentrations and there are multiple Method Blanks for a sample set, use the brackets to assign Method Blank data to specific data sets.

Poisson Discrete Distribution Adjustment Factor:10
Note: All sample concentrations are micrograms per liter
Using the background data, the upper Poisson Prediction Limit, y*, is determined by:
y* = c y + [(t^2) c / 2] + t c [y (1 + (1/c)) + ((t^2) / 4)]^0.5
where:c = k / n
y = Poisson count
t = t(n-1, 0.95), Student's t-distribution
n-1 = degrees of freedom (number of samples - 1)
k = number of downgradient samples per event
.95 = confidence interval
n = number of background samples
For:c = 0.215
y = 4078
t = 1.662
k = 20
n = 93
y* = 931.54
Adjusted y* = 93.15 µg/L
