EXECUTIVE SUMMARY
The Harnett County Dunn-Erwin Landfill is located at NC State Road 1724/449 Daniel’s Road,
Dunn, North Carolina. The facility contains an active C&D landfill, active LCID landfill and
closed unlined MSW landfill under Solid Waste Permit #43-02. According to the 1985 North
Carolina Geological Map the landfill is situated in the Coastal Plain Physiographic Province. The
Dunn–Erwin area in Harnett County is underlain by the Cretaceous age Middendorf formation
that is primarily light gray sand, sandstone and mudstone which acts as a confining unit.

Groundwater depths historically range from 5 ft to 25 ft below ground surface (bgs) across the
facility. Groundwater generally flows west toward Stewart Creek and south to an unnamed
tributary of Stewart Creek.

After several years of phytoremediation and natural attenuation processes, the constituents
that continue to be of concern are: 1,1-dichloroethane, benzene, methylene chloride,
tetrachloroethene and vinyl chloride. Historically, 1,4-dichlorobenzene and trichloroethene
were also considered constituents of concern; however, these are proposed for removal as
constituents of concern due to lack of detected concentrations above their 2L standards.

The 2009 CAP written by C.T. Clayton proposed a phased remedial strategy. The first phase was
phytoremediation, which has been implemented and shown to be an effective and cost efficient
technology in the area near groundwater monitoring wells MW9 and MW-10. The second phase
was additional phytoremediation further from the landfill and installation of an approximately
1500 foot trench for groundwater collection and treatment installed immediately downgradient
of the landfill. This second phase has not been implemented.

The groundwater monitoring plan implemented in 2013 has been effective in tracking
constituents of concern and monitoring the overall groundwater quality at the Dunn Erwin
Facility. We propose to modify the Corrective Action to apply Monitored Natural Attenuation for
impact detected in wells MW-57, GP-28W and PZ-41s. MNA parameters will be added to these
wells We further propose to remove MW-9, MW-10 and GP-30 from the MNA parameter list,
due to lack of VOC detections from samples at these locations

1.0 INTRODUCTION
The Harnett County Dunn-Erwin Landfill is located at NC State Road 1724/449 Daniel’s Road,
Dunn, North Carolina. The facility contains an active C&D landfill, active LCID landfill and
closed unlined MSW landfill under Solid Waste Permit #43-02. A transfer station also operates
at this location under SWS permit #43-07T. The surrounding area is generally agricultural and
undeveloped land. The landfill is located approximately two miles north of the Town of Erwin. A
topographic map showing the site location is included as Figure 1.
1.1 Site Background
The facility began operation in 1978 and the former unlined MSW landfill was closed in
December 1998 and was capped in accordance with Rule 15A NCAC 13B .16927 (c)(10).
Currently, C&D waste is being placed over the closed, capped MSW landfill, in
accordance with SWS approval. A site map with aerial photo is included as Figure 2.

Harnett County retained C.T. Clayton, Sr., P.E. Inc., (C.T. Clayton) to develop their
Assessment of Corrective Measures (ACM)1 (Doc ID 6472) and Corrective Action Plan
(CAP)2 (Doc ID 8742) for the Dunn-Erwin facility.
1.2 Sampling History
Groundwater records are available as far back as 1986; however routine semi-annual
monitoring began in 1997. Available well construction details are presented in Table 1.
Historic groundwater elevations are presented in Table 2. In 2003 C.T. Clayton
performed a study to evaluate a contamination plume in the upper aquifer located west
of the active C&D over closed MSW unit. This study resulted in an additional twelve
monitoring wells installed. Additionally, pump tests were performed on MW-9 and MW-
10 in 2004. In 2008 additional sampling and organic compound (8260B) analysis was
conducted to refine the plume boundary for the ACM.

Groundwater sample analysis for the list of Appendix I parameters has been performed
semi-annually since 1997. Following corrective action implementation Appendix II
analysis was conducted on select wells. In October 2013, S+G revised the water quality
monitoring plan for the Dunn Erwin facility. This plan reduced the monitoring network to
20 locations and specified MNA parameter analysis from select well samples annually.

1.3 Aquifer Characteristics
According to the 1985 North Carolina Geological Map the landfill is situated in the
Coastal Plain Physiographic Province. The Dunn–Erwin area in Harnett County is
underlain by the cretaceous age Middendorf formation that is primarily light gray sand,
sandstone and mudstone which acts as a confining unit. The Middendorf formation was
deposited in a deltaic system and varies from 15m to over 100m thick.

Groundwater depths historically range from 5 ft to 25 ft below ground surface (bgs)
across the facility. Groundwater generally flows west toward Stewart Creek and south
to an unnamed tributary of Stewart Creek. There are minor seasonal variations in the
flow pattern, but overall flow direction is consistent. The potentiometric surface map
showing the October 2015 groundwater surface is presented as Figure 3. Measured
groundwater velocity at the site is presented in Table 3.

There are no public water supply wells within two miles of the landfill. Harnett County
supplies water to the surrounding area from the main water line originating in Lillington,
NC. No surface water intakes are located within two miles of the Dunn-Erwin landfill
Facility.
1.4 Contamination Distribution
The constituents of concern identified in the CAP were

• benzene,
• 1,1-dichloroethane,
• 1,4-dichlorobenzene,
• methylene chloride,
• tetrachloroethene,
• trichloroethene,
• vinyl chloride
• inorganic compounds lead
and mercury.

After several years of phytoremediation and natural attenuation processes, the
constituents that continue to be of concern are: 1,1-dichloroethane, benzene, methylene
chloride, tetrachloroethene and vinyl chloride. 1,4-dichlorobenzene and trichloroethene
are have not recently been detected at concentrations above their standards set forth in
15A NCAC 2L.0100 et seq. (2L Standards). Historic VOC concentrations are presented in
Table 4.

Volatile organic compound (VOC) detections are limited to the area west (downgradient)
of the active C&D over closed MSW landfill. Reviewing groundwater quality data since
2013, MW-2 (the background/comparison well), MW-9, MW-10, MW-33, MW-56 and PZ-
41S have no VOC detections indicating natural attenuation and phytoremediation
processes have been successful at these locations. In general, recent detections are
primarily in samples from wells MW-53, MW-57 and GP-28. Please note the property
line is 1300 feet downgradient at its closest point to MW-9 and MW-10 and is 500 feet
from monitoring well GP-28.. Wetlands, which naturally polish groundwater, are located

Harnett County Dunn Erwin Landfill Corrective Action Evaluation Report
September 2016 Page 2
between GP-28 and the property line. Detections over 2L standards from the October
2015 sampling event are shown on Figure 4.

Inorganic metal analysis for mercury was only reported above the 2L in one sample from
MW-9 during the October 2014 sampling event. Lead concentrations have been
historically reported above the 2L groundwater standards in wells around the site;
however, exceedances of 2L standards have not been consistently detected in certain
wells. The haphazard nature of lead exceedances is likely related to naturally occurring
lead concentrations in the soils at the site, and tubidity in the samples which can bias
inorganic results high. Lead concentrations measured at the site are consistent with
on-site soils and National Uranium Resource Evaluation NURE database of geochemical
stream and sediment data. Historic inorganic constituents are presented in Table 5.
Available well records are provided in Appendix A.
1.5 Regulatory Status
Harnett County operates a C&D landfill over a closed, unlined MSW landfill at the Dunn-
Erwin Facility (SWS Permit No. 43-02). Dunn-Erwin has been operating under a CAP
since 2009. In 2013 Smith Gardner, Inc. (S+G) requested and was approved3 two years to
further evaluate groundwater trends at the facility and determine what next steps may
be necessary for groundwater corrective action.

2.0 CORRECTIVE ACTION SUMMARY
Phytoremediation was implemented downgradient of the unlined MSW landfill in 2010 as part of
the approved 2009 CAP strategy presented by C.T. Clayton. Currently, trees range from 3 to 5
feet in height, with trunks about two inches thick. Monitoring wells MW-9 and MW-10, located
at approximately the 250 foot compliance boundary, are positioned within the phytoremediation
zone have remained free from VOC detections over the past two years. Additionally, well GP-
30W (positioned downgradient from MW-9, MW-10 and the phytoremediation area has remained
free from VOC detections.
2.1 Aquifer Conditions
The groundwater contamination source appears to be the former unlined MSW landfill
unit under the active C&D landfill. The downgradient contamination mechanism is likely
due to precipitation that has percolated through the landfill waste, allowing VOCs to
partition from solid/liquid phases into a dissolved phase, and subsequently migrated
downwards to mix with groundwater. The 2009 CAP identified benzene, 1,1-
dichloroethane, 1,4-dichlorobenzene, methylene chloride, tetrachloroethene,
trichloroethene, vinyl chloride and the inorganic compounds mercury and lead as
constituents of concern. VOC detections have been reported in samples collected from
well locations past the 250 foot compliance boundary.
2.1.1 Physical Changes
Harnett County has continued with C&D landfill operation above the unlined
MSW. Several hundred trees were planted in the spring of 2010 covering
approximately 2.5 acres, as part of the Corrective Action remedial strategy.
2.1.2 Chemical Changes
Of the chemical constituents of concern listed above, 1,4-dichlorobenzene, and
trichlorethene, have not been detected during the past two years.

Samples from well locations inside and downgradient of the phytoremediation
area have reduced VOC detections from above 2L to primarily non-detect and
non-quantifiable concentrations. Well locations MW-53 and MW-57 are located
at approximately the 250 foot compliance boundary. GP-28 is located
approximately 485 feet downgradient from the edge of waste and is located
approximately 500 feet from the property line.
2.2 Plume Characteristics
2.2.1 Physical Changes

Harnett County Dunn Erwin Landfill Corrective Action Evaluation Report
September 2016 Page 4
Reported detections remain inside the property boundary. GP-28 is located over
one thousand feet from the closest property boundary. No detections in surface
water features around the facility indicate local drainage features remain free
from impact.

Constituents of concern are primarily reported in samples from MW-53, MW-57
and GP-28. Concentrations remain primarily stable or are slightly decreasing.
This plume area has decreased since the 2009 CAP.
2.2.2 Chemical Changes
Biochlor is an EPA screening tool, designed to simulate natural attenuation of
chlorinated solvents. Biochlor models were created for the plume area outside
of the phytoremediation zone (MW-53 and GP-28). Other wells were not analyzed
with Biochlor due to decreased concentrations of constituents of concern.

The Biochlor models were run using the maximum and minimum
biotransformation to determine the potential degradation range. Biochlor
results are presented in Appendix B. These results indicate biotransformation is
occurring at the site.

Harnett County Dunn Erwin Landfill Corrective Action Evaluation Report
September 2016 Page 5
3.0 CORRECTIVE ACTION PLAN UPDATES
The 2009 CAP proposed a phased remedial strategy. The first phase was phytoremediation,
which has been implemented and shown to be an effective and cost efficient technology in the
MW9 and MW-10 area. The proposed second phase of the CAP included additional
phytoremediation further downgradient of the landfill and installation of an approximately 1500
foot trench located at the toe of the landfill for groundwater collection and treatment. The
proposed second phase has not been implemented.

A number of factors were reviewed to evaluate the site’s corrective action, including:.

• Groundwater contamination exists at relatively low concentrations (ppb range).
• Based on Biochlor modeling, natural attenuation is already occurring at the site.
• Phytoremediation has been effective in the removal of VOCs from groundwater in the
vicinity of MW-9 and MW-10.

Remediation of relatively low-level contamination in the 100ppb or less range can be difficult,
expensive and may not be achievable by conventional methods. A multi-phase approach
provides the best opportunities for success.
3.1 Modifications to Selected Remedy

Due to the success of phytoremediation in the downgradient area surrounding wells
MW-9 and MW-10, maintenance on the existing phytoremediation area will continue.
This will include mowing between tree rows and observations of tree leaves and overall
tree health. The data collected during the past two years suggests options other than
the second phase strategies originally proposed in the 2009 CAP should be considered.
These are discussed in more detail below.

VOCs have been detected in the unconfined aquifer monitored by MW-57, MW-53, PZ-
41S, and GP-28 at concentrations that exceed 2L or Groundwater Protection Standards.
These wells are located downgradient of the closed MSW landfill and GP-28W is
downgradient of the phytoremediation area. Although the phytoremediation area
appears to be having a positive effect on groundwater quality, the leading edge of the
plume may be beyond its influence. Due to the significant distance to the property line
(>500 feet) we believe natural attenuation is the most appropriate remedial strategy for
impacted groundwater in this area. There are significant wetlands between the
impacted wells and the property line. Wetland plants and soils have been used for
cleaning impacted water (including leachate) at a variety of facilities. Due to the location
of these wetlands, we believe natural attenuation will be effective in treating impacted
water in this area. Modifications to the monitoring network and parameters are
discussed below.

Harnett County Dunn Erwin Landfill Corrective Action Evaluation Report
September 2016 Page 6

3.2 Modifications to Monitoring Parameters and Schedule
We propose to add existing monitoring well PZ-47s to the monitoring network as a
“Sentinel Well”. This well is located downgradient of GP-28W and MW-57 and will
monitor closer to the property line in this area. Currently groundwater samples from
MNA monitoring wells (MW-2, MW-9, MW-10, GP-30W and MW-53) are analyzed semi-
annually for Appendix I VOCs and metals plus mercury, with annual analysis for
alkalinity, sulfide, TOC, dissolved methane, iron, chloride, nitrate, dissolved oxygen (DO)
and oxygen reduction potential (ORP).

We propose to remove MW-9, MW-10 and GP-30W from the MNA parameter list and
replace them with MW-57 and PZ-47s. There will be no other changes to the
groundwater monitoring program at this time. The proposed monitoring network and
analysis is summarized below.
