Subject: Buncombe County Monitor Natural Attenuation Fall 2015 Report
Dear Michael:
SCS Engineers, P.C. (SCS) is submitting the attached report for the latest round of groundwater
sampling at the Old Buncombe County Landfill in hard copy as requested. Three rounds of semi-
annual sampling for MNA parameters have been completed and are shown on Table 4. As we
discussed in the June 8, 2015 Response to Comments of the UIC Permit Application, there is no
major impact from the injectants observed in the sampling performed immediately after the
injection event. The Spring Sampling event is being conducted this month and we expect to see
the beginning effects of the extended release product at that time, but consistent with the
previous HRC injection and sampling, it may be a year before effects are observed in the
groundwater quality data.
If you have any questions please feel free to contact us.
Sincerely,

Old Buncombe County Landfill i MNA Sampling Report
I Solid Waste Services
1 INTRODUCTION
The Buncombe County unlined municipal solid waste landfill located at 2726 Riverview Road
near Asheville NC, has commenced Monitored Natural Attenuation (MNA) monitoring in
accordance with the Corrective Action Plan (CAP) approved September 24, 2014. The Fall
sampling event was performed between October 12 and October 19, 2015 along with traditional
semi-annual sampling.
The Old Buncombe County Landfill (OBCL) is closed and currently monitored under post -
closure care. The OBCL collected waste streams in unlined waste areas approved to receive
municipal, industrial, and construction solid wastes, along with household waste and yard debris.
Leachate from the waste areas have contaminated the groundwater as evidenced from the
presence of chlorinated solvents detected in groundwater from down -gradient monitoring wells
in excess of North Carolina Department of Environment and Natural Resources (NCDENR)
standards beginning in 1985 to the present.
Waste Areas A, B, and C stopped receiving waste prior to October 9, 1991. Area D stopped
accepting waste on September 27, 1997 in accordance with the North Carolina Solid Waste
Management Rule T15A: 13B .1 627(c)(1 0)(A). Institutional controls are in place which restricts
the use of, access to the site, and eliminates or minimizes exposure to site contaminants. All
disposal areas have been closed and capped in accordance with permit modifications for closure
under 15A North Carolina Administrative Code (NCAC) Chapter 13B.
The landfill site has controlled access and perimeter fencing to limit site access. An active gas
collection system was constructed and is operated by Enerdyne. This system generates power
from a small facility located on the property. The County has constructed a Safety Training
Facility on property outside of the waste fill area but within the original landfill property limits.
Multiple buildings have already been constructed and others are in the planning stages. This area
has controlled access and perimeter fencing that isolates its development from the balance of the
landfill property. The habitable buildings in this area are equipped with sub floor vapor
extraction systems and gas detectors that are monitored continuously by on -site personnel. While
these vapor intrusion controls have been installed specifically to address potential methane gas
issues, it is expected that the vapor systems in permanently occupied spaces will also help to
mitigate any potential issues arising from a vapor intrusion pathway.
The groundwater plume has been monitored over the years by a series of monitoring wells
- around the perimeter of the landfill (see Figure 1, Appendix A). Currently 24 monitoring wells
are sampled semi-annually (DPL-2 was converted to an Injection Well prior to the October 2015
sampling event). Groundwater samples collected from these wells have been analyzed for the
typical landfill parameters (metals, semi -volatile organic compounds, volatile organic
compounds, etc.. Concentrations in p ) excess of the Title 15A NCAC Subchapter 2L (NC2L)
r Old Buncombe County Landfill 1 -2 MNA Sampling Report
groundwater standards have been reported primarily for metals and volatile organic compounds
(VOCs). The extent of the groundwater plume has been delineated and concentrations of
contaminants have generally been declining. Additional remedial measures, enhanced in -situ
bioremediation (EIB) were performed in September 2015 in accordance with the March 2015
CAP Addendum and the Injection Permit WI0100353.
Five main groundwater flow paths, referred to as transects, have been identified down -gradient
from the OBCL waste piles presented below.

Transects 1 and 5 appear to be long enough to naturally attenuate VOCs observed immediately
down -gradient from the waste piles prior to reaching the French Broad River. MNA is the only
remedial activity for Transects 1 and 5. Transect 2 appears to have been successfully remediated
following the pilot testing of EIB using hydrogen release compound injection. Transect 3 and 4
show contaminants reach the French Broad River before natural attenuation processes may
completely de -chlorinate site VOCs. Therefore more aggressive clean-up actions consisting of
enhancing natural attenuation through substrate addition were implemented along the short flow
path system.
DPL-2 and the newly installed IW-1 were used as the fractured bedrock injection points for
substrate addition based on their close proximity to the source plume. Direct injection to the base
of the regolith was also used to treat the high flow zone which may be used to remediate both
short and long fracture controlled flow paths along Transects 3 and 4. Substrate addition was
conducted in September, 2015 prior to the Fall 2015 semi-annual sampling event.
2 SEMI-ANNUAL SAMPLING
Metals and VOCs were detected in ground water samples which exceeded NC2L Groundwater
Standards in concentrations which are consistent with previous sampling results. Surface water
sampling demonstrated no constituents were above their SWS reporting limits.
Twenty one monitoring wells are sampled during the Fall 2015 event, three monitoring wells
were dry and no samples were collected (DPL-1, MW-24-45, and MW-7). Groundwater samples
were collected from October 13th through 19"', 2015. The four surface water samples were
collected on October 12th, 2015. All samples were collected and analyzed by Pace Laboratories
( in Asheville, NC for analysis of Appendix I and II constituents list as well as MNA parameters
as specified in Appendix B, Table 1.
Groundwater elevations were also measured and a groundwater contour map for both the shallow
-- and deep flow regimes as presented in Appendix A. Field parameters and the well condition
were evaluated as presented in Appendix C Well Condition Summary and Append
ix D
Sampling Forms. Field parameters included: pH, specific conductivity, temperature, dissolved
' oxygen, and oxidation/reduction potential, temperature, and turbidity. Field parameters were also
measured at the surface water sampling locations.
Eleven of the 21 monitoring wells had concentrations in excess of the NC2L Groundwater
Standards. No surface water samples had concentrations in excess of the SWS reporting limits. A
summary of detections is provided in Appendix E; a summary of exceedances is provided as
Appendix F. The exceedances were consistent with historic concentrations at their respective
wells. A summary of the contaminants exceeding the NC2Ls is presented as Appendix B, Table
2.
VOC constituents detected include 1,1-dichloroethane, 1,2-dichloropropane, 1,4-
dichlorobenzene, 2-butanone, 2-hexanone, 4-methyl-2-pentanone, acetone, benzene,
chlorobenzene, chloroethane, cis-1,2-dichloroethene, ethylbenzene, tetrachloroethene, toluene,
trichloroethene, vinyl chloride, and xylene. 1, 1 -dichloroethane was detected above the maximum
contaminant level of 6 ug/L in MW-21-21 (8.6 ug/L), MW-3 (12 ug/L), and MW-4 (16.7 ug/L).
1,2-dichloropropane was detected above the maximum contaminant level of 700 ug/L in MW-
13-132 (1.4 ug/L). 1,4-dichlorobenzene was detected above the maximum contaminant level of 6
ug/L in MW-13-35 (45 ug/L),.MW-21-21 (10.3 ug/L), MW-3 (9.1 ug/L), MW-4 (11.3 ug/L),
MW-4A (86.5 ug/L), and MW-5 (7.4 ug/L). Benzene was detected above the maximum
contaminant level of 1 ug/L in MW-13-132 (1.1 ug/L), MW-13-35 (2.3 ug/L), MW-3 (1.1 ug/L),
MW-4A (5.3 ug/L), and MW-6 (1.3 ug/L). Tetrachloroethene was detected above the maximum
contaminant level of 0.7 ug/L in MW-4 (1.2 ug/L). Vinyl chloride was detected above the
maximum contaminant level of 0.03 ug/L in MW-18-78 (1.6 ug/L), MW-21-21 (2.4 ug/L), MW-
3 (3.4 ug/L), MW-4 (3.1 ug/L), and MW-B (2.1 ug/L).
Metal constituents detected include antimony, barium chromium, cobalt, iron, lead, manganese,
nickel, selenium, vanadium, and zinc. Antimony was detected above the maximum contaminant
level of 1 ug/L in MW-15 (12.4 ug/L), and MW-4 (5.3 ug/L). Barium was detected above the
maximum contaminant level of 700 ug/L in MW-6 (1410 ug/L). Chromium was detected above
the maximum contaminant level of 10 ug/L in MW-15 (12.6 ug/L). Cobalt was detected above
the maximum contaminant level of 1 ug/L in MW-21-21 (6.1 ug/L), MW-3 (22 ug/L), MW-4
(64.4 ug/L), MW-4A (32 ug/L), and MW-5 (25.5 ug/L). Nickel was detected above the
maximum contaminant level of 100 ug/L in MW-4 (109 ug/L).
Metals were detected in the surface water samples including: barium, chromium, cobalt, copper,
nickel, vanadium, and zinc. Concentrations were below their SWS reporting limits.
Pace analytical laboratories collected groundwater samples, to be tested for MNA parameters,
from 10 monitoring wells (MW-2, MW-4, MW-6, MW-13-132, MW-18-78, MW-19-75, MW-
19-110, MW-21-21, MW-21-94, and MW-24-160). Sampling was conducted per the
methodology listed in the approved CAP Groundwater and Surface Water Sampling and
Analysis Plan for the constituents listed in Appendix B, Table 3. These results were evaluated
using the EPA Technical Protocol for Evaluating Natural Attenuation of Chlorinated Solvents
(EPA 1998). A summary table of 2014 and 2015 baseline MNA sampling results is presented as
Appendix B, Table 4. Screening results indicate that there is adequate information to suggest
natural attenuation is occurring at the performance well locations. Further, screening results
indicate that there is strong information to suggest natural attenuation is occurring at the
transect3 and 5 sentinel well locations.
The range of hydrogen concentrations for a given terminal electron -accepting process show
sulfate reduction as the likely MNA process for all three rounds of MNA parameter sampling
with some evidence of methanogenesis in the very deep flow regimes based on elevated
hydrogen concentrations during the Spring 2015 sampling event.
3 BIOCHLOR
The analytical model solution BIOCHLOR (Aziz et al. 1999) provides an integrated platform for
analyzing site data and to confirm or quantify attenuation. BIOCHLOR simulates solute
transport assuming 1-D advection, 3-D dispersion, linear adsorption, and biotransformation via
reductive dechlorination (the dominant biotransformation process at most chlorinated solvent
sites). Reductive dechlorination is assumed to follow a first -order decay process. BIOCHLOR
Modeling Input rationale and model runs are presented as Appendix E. Model results must be
considered qualitative because of the limitations of the BIOCHLOR model and site
heterogeneity. Transect 4 were selected for modeling chlorinated ethenes.
A model of Transect 4 using historical contaminant data was developed and calibrated to current
site data for chlorinated ethenes. The Transect 4 model was then used to help predict future
behavior with current conditions (same biotransformation coefficients and inputs) and also with
future conditions expected following addition of EIB substrate (reduced half-life of calibrated
model). Both PCE and VC showed no impact to the boundary point of compliance with
biotransformation occurring which correlates well with historical data. Plume contraction was
modeled to occur by 2028 at the current rate of dechlorination. A 50% decrease in degradation
half-life correlates to a six year reduction in estimated plume contraction. A 50% decrease in
degradation half-life used for the predictive model is anticipated to be conservative given the
microcosm half-life measurements. The BIOCHLOR inputs and models for PCE and VC are
presented as Appendix G.
4 CONCLUSION
The OBCL data presented in this report provides multiple lines of evidence to demonstrate
natural attenuation is occurring on site in accordance with EPA Technical Protocol for
Evaluating Natural Attenuation of Chlorinated Solvents (EPA 1998). Overall contaminant
concentrations of highly chlorinated VOCs have been decreasing. Fall 2014 MNA sampling data
were evaluated using EPA's NINA screening tool, screening values indicate that there is strong
information to suggest natural attenuation is occurring in all four MNA performance wells.
BIOCHLOR modeling has been presented showing natural attenuation through sequential 1 St
order decay.
MNA Sampling will continue for one more round of baseline sampling conducted in conjunction
with site -wide semi-annual compliance monitoring. BIOCHLOR models will be further
calibrated with future analytical results.

acceptor used by microbes.
Nitrate
EPA 353.2
Used as an electron acceptor by denitrifying
bacteria if oxygen is depleted.
Iron (II)
EPA 6010
Indicator of iron reducing bacteria.
Sulfate
EPA 300.0
Used as electron acceptor. Provide evidence of
sulfate reducing bacteria.
Sulfide
Field meter
Daughter product of sulfate reduction. May not be
SM 4500 S D
detected even if sulfate -reducing bacteria are
active because it can react with various
oxygenated chemical species and metals.
Methane, ethane,
Bubble Strip Sampler
Provide evidence of complete dechlorination of
ethene
AM 20 GAX
chlorinated ethenes, and ethanes. Methane also
indicates activity of methanogenic bacteria.
Oxidation
Field meter
Influences and is influenced by the nature of
