1 INTRODUCTION
Buncombe County (County) recently received a letter from the Department of Environmental
Quality (DEQ) notifying the County that action on the County’s part is required due to
exceedances reported on the metals in the groundwater at the landfill. SCS Engineers, PC (SCS)
was contacted by the County to address the issue for them. The letter outlined two alternatives
for the County’s response, which are: initiate an assessment monitoring program, or initiate an
Alternate Source Demonstration (ASD).
Since Appendix I Inorganic Constituent Exceedances in the monitoring wells have been
documented since before waste was placed in the landfill and on a continuing basis since
baseline sampling, an assessment program is not justified. This ASD includes a geological
review, total and dissolved metals groundwater sampling, and statistical analyses using both
historical baseline groundwater data and compliance monitoring data upgradient and
downgradient of the units being monitored. Monitoring wells downgradient of the unlined
Construction and Demolition disposal cell (MW-12, MW-12D, MW-14, MW-14D, MW-15, and
MW-15D) are not subject to the ASD requirements and were therefore not included in this
report.
2 GEOLOGIC SETTING
The Buncombe County Landfill site is located in the Blue Ridge Mountains approximately 9
miles north of Asheville, North Carolina. The landfill site consists of 557 acres bounded by the
French Broad River to the south and west, Blevin Branch to the north, and Flat Creek to the east.
The site consists of moderate to steep slopes separating narrow hills and ridges from small
incised secondary drainages. The Buncombe County Landfill Site Figure is provided as
Appendix A.
3 SITE GEOLOGY
The Geologic Map of North Carolina shows the site to be underlain by a Precambrian Migmatitic
biotite-hornblende gneiss unit (NCGS 1985). The site vicinity was mapped as primarily granite
and undifferentiated gneiss (Weiner 1970 and GRAM 1999).
Small localized areas of alluvium and/or colluvium were encountered near the base of the
secondary drainage features. These soils generally consisted of clays to silty sand with rock
fragments. Typically, the uppermost layer consisted of residuum soils (saprolite) which generally
consist of stiff sandy silts and dense clay. The saprolite grades into partially weathered rock
(PWR). The thickness of saprolite and PWR was greatest in upland areas, and least in the bottom
of secondary drainage features. Depth to bedrock, ranges from 3.5 feet to 29 feet. The top of
bedrock is typically a reflection of surface topography, with shallow bedrock in the secondary
drainage features, and deeper bedrock in upland areas.
4 SITE HYDROGEOLOGY
As with bedrock, the potentiometric surface is a subdued reflection of surface topography. The
bedrock fracture flow system behaves similar to an anisotropic porous media, based on the
Alternate Source Demonstration

potentiometric mapping results of pumping tests conducted during previous investigations at the
Buncombe County site (CDM, 1995, 2002). Groundwater Contour Maps from the October 2016
Semi-Annual Sampling event are provided in Appendix A.
Dissolved chemicals in groundwater may be derived from rock weathering, biological processes,
and anthropogenic sources. Dissolution of minerals in bedrock and overlying geologic materials
commonly release naturally occurring constituents to the groundwater (Chapman and others,
2013). Groundwater from diverse environments may contain naturally occurring trace elements
such as iron, manganese, zinc, lead, copper, nickel, vanadium, molybdenum, and arsenic (Rose
and others, 1979).
According to Naturally Occurring Contaminants in the Piedmont and Blue Ridge Crystalline-
Rock Aquifers and Piedmont Early Mesozoic Basin Siliciclastic-Rock Aquifers, Eastern United
States, 1994–2008, dissolved concentrations of trace constituents can range widely depending on
their occurrence in the saprolite and PWR (Chapman and others, 2013).
5 REGIONAL STREAM SEDIMENT
A geochemical atlas of North Carolina, U.S.A. was prepared using National Uranium Resource
Evaluation (NURE) stream-sediment data. Stream sediment of weathered bedrock typical of the
nearby source formations was developed to assist mineral exploration. These data also serve to
provide a baseline from which to assess naturally occurring metals in landfill saprolite and PWR.
The maps included herein represent findings for arsenic, barium, beryllium, chromium, cobalt,
copper, iron, lead, manganese, nickel, selenium, silver, vanadium, and zinc. The sediment
graphics indicate the natural presence of the metals in the soils of that region of the state where
the landfill is located. Note that the sediment study did not include antimony, cadmium, and
thallium. However, the presence of the other metals at the site would indicate that naturally
occurring metals in the mountain region are common. Stream Data Maps are provided as
Appendix B.
6 GROUNDWATER MONITORING
The Solid Waste Management Rule 15A NCAC 13B.1632 requires new MSWLF units establish
background groundwater quality to demonstrate compliance with groundwater monitoring
requirements. The initial baseline sampling event for the Buncombe County Solid Waste
Management Facility was completed in October 1996 with the remaining three background
sampling events completed in June, August, and September of 1997. Monitoring the background
wells MW-1 and MW-1D, and the compliance wells MW-2, MW-2D, MW-3, MW-4, MW-4D,
MW-5, MW-5D, MW-6, MW-7, MW-8, MW-8D.
Arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, lead, nickel, vanadium, and
zinc were all detected in the baseline sampling events prior to beginning operations. Exceedances
of the North Carolina groundwater standards were noted also for the metals barium, chromium,
lead and nickel as shown in Table 1 Initial Baseline Sampling, Appendix C.

Since the Buncombe County Landfill (Permit #11-07) initially opened, the groundwater and
surface water has been monitored twice annually. Many of the wells, including background,
show metals detections. Background well MW-1 has shown detectable concentrations of
additional metals antimony, iron, manganese, selenium, silver, and thallium since the baseline
sampling. Background well MW-1D has shown detectable concentrations of additional metals
iron, manganese, and silver since the baseline sampling.
The background and compliance wells on the site have shown detections of metals above the
exceedance level since the initial reports in 1998 were filed with the North Carolina Department
of Environment and Natural Resources. Antimony, arsenic, barium, beryllium, cadmium,
chromium, cobalt, iron, lead, manganese, nickel, thallium, and vanadium have all been detected
above groundwater quality standards. Compliance Monitoring Well Exceedance Summary
Report is provided as Appendix D.
7 TIME SERIES GRAPHS
Graphical methods are typically used with quantitative statistical evaluations. Graphical methods
provide information that may not be otherwise apparent from quantitative statistical evaluations,
so it’s good practice to evaluate data using these methods prior to performing statistical
evaluations.
Time series graphs of the metals concentrations and field turbidity measurements demonstrate a
strong correlation with turbidity measurements for the metals barium, beryllium, cadmium,
chromium, iron, lead, manganese, nickel, and vanadium. Arsenic, cobalt, and thallium time
series graphs did not correlate well with turbidity measurements because of small data sets and
changing laboratory detection limits. Time Series Graphs are provided as Appendix E.
Outliers data which appears anomalous or outside the range of expected values may indicate
errors, may indicate data unrelated to the rest of the data set, or may be perfectly valid data that
indicates contamination or unusual hydrogeological conditions. Possible reasons for outliers are
recording errors, unusual sampling and laboratory procedures or conditions, or inconsistent
sample turbidity. The trend of decreasing turbidity and metals concentrations can be attributed to
better sampling equipment and methods practiced over the years.
To try to ascertain whether or not the metals were in the water and not suspended particles, SCS
previously tested filtered samples and additionally redeveloped some of the wells resulting in
lower concentrations between filtered and unfiltered samples. SCS again tested filtered samples
in the last semi-annual groundwater monitoring event where turbidity measurements were lower
than historical sampling turbidity measurements. Dissolved metals concentrations were only
marginally below the unfiltered sample concentrations. The results of the Fall 2016 activities
would indicate that the metals are dissolved in the groundwater.
8 STATISTICAL ANALYSIS
Background is defined as groundwater which is not influenced by releases from a site.
Specifically, a background groundwater data set may represent either a location or a time period
that has not been influenced by a release from the site. The concentration of a chemical will

naturally vary both spatially and temporally. The analytical process introduces additional
variability. Because of both natural and introduced variability, background can best be
understood as a distribution (ITRC, 2013). Statistical analysis was performed to determine if the
distribution of concentrations are consistent with the distribution of concentrations in
background samples. In accordance with Solid Waste Management Rule 15A NCAC 13B.1632,
historical compliance groundwater monitoring data were pooled and the analytical results were
used to create a statistical baseline for statistically significant increases in constituent
concentrations.
The parametric analysis of variance (ANOVA) is a statistical method which is used to do the
analysis of variance between and within multiple groups of data. The ANOVA tests the null
hypothesis that samples in two or more groups are drawn from populations with the same mean
values. Chemstat 6.2.1.0 statistical software was used to analyze the compliance monitoring data.
Parametric ANOVA analysis. The Parametric ANOVA analysis showed no statistical difference
between compliance well metal concentrations and background well data for antimony, arsenic,
cadmium, iron, manganese, and thallium. The Parametric ANOVA analysis showed a statistical
difference between compliance well metal concentrations and background well data for barium,
beryllium, chromium, lead, nickel, and vanadium. There were no detectible concentrations of
cobalt in the compliance monitoring samples and the parametric test could not be performed, it
should be noted however that cobalt was detected in the background wells during baseline
sampling. Parametric ANOVA Analysis results are provided as Appendix F.
Intrawell comparisons were made where statistically different metals exceedances were noted.
Concentrations of barium were statistically higher than background (MW-1/ MW-1D compliance
data) concentrations in MW-2. Barium was detected in MW-2 during the baseline sampling at a
concentration higher than the compliance monitoring results demonstrating natural occurrence
for this constituent in MW-2.
Concentrations of beryllium were statistically higher than background concentrations in MW-2
and MW-6. Beryllium was detected in MW-2 and MW-6 during the baseline sampling at
concentrations higher than the compliance monitoring results demonstrating natural occurrence
for this constituent in MW-2 and MW-6.
Concentrations of chromium were statistically higher than background concentrations in MW-6.
chromium was detected in MW-6 during the baseline sampling at a concentration higher than the
compliance monitoring results demonstrating natural occurrence for this constituent in MW-6.
Concentrations of lead were statistically higher than background concentrations in MW-2. Lead
was detected in MW-2 during the baseline sampling at a concentration higher than the
compliance monitoring results demonstrating natural occurrence for this constituent in MW-2.
Concentrations of nickel were statistically higher than background concentrations in MW-7.
Nickel was detected in MW-7 during the baseline sampling at a concentration higher than the
compliance monitoring results demonstrating natural occurrence for this constituent in MW-7.
Concentrations of vanadium were statistically higher than background concentrations in MW-6
and MW-7. Vanadium was detected in MW-6 during the baseline sampling at a concentration

higher than the compliance monitoring results demonstrating natural occurrence for this
constituent in MW-6 and MW-7.
9 CONCLUSION
The ASD is being performed to demonstrate that natural variability in the fractured bedrock and
saprolite aquifer system has resulted in metals concentrations that vary both spatially and
temporally. This natural variation was identified as the source of the sporadic detections of
metals above its background limit.
Metal concentrations in the groundwater have been shown to be naturally occurring substances
present in the environment. This natural variation has been documented in stream sediments,
baseline groundwater sampling conducted before waste was placed in the landfill, and
quantitative statistical evaluations.
