REMEDIAL ACTION PROGRESS REPORT

MOUNT HOPE MACHINERY MECKLENBURG COUNTY, NORTH CAROLINA JULY 10, 2015

1.0 INTRODUCTION
1.1 Background
In 1989, a remedial investigation was initiated at the Mount Hope facility located at 2000
Donald Ross Road, Charlotte, North Carolina to assess a release of varsol and mineral spirits from
a permitted subgrade septic tank system. Aware Environmental, Inc. (AEI) was engaged by the
owner to evaluate the issue. This investigation revealed that both soil and groundwater were
impacted by the release. The subject property is currently vacant and offered for sale by the owner.

Remedial activities were conducted at the site between May 1992 and May 1998 to address
the impacted soil and groundwater with regulatory oversight by the North Carolina Department of
Environment and Natural Resources (NCDENR) – Groundwater Section. Remedial activities
included removal of the septic tank system and surrounding soil excavation, soil vapor extraction
(SVE), and shallow groundwater air sparging (AS) in proximity of the source area. Between
January 1996 and November 1998, quarterly groundwater sampling was conducted at the site to
evaluate groundwater remedial efforts.

After Mount Hope conducted the initial soil and groundwater remedial activities,
regulatory oversight of the release incident fell under the purview of the NCDENR Inactive
Hazardous Sites Branch (IHSB). A more recent remedial investigation conducted in 2009 and 2013
under the IHSB’s Registered Environmental Consultant (REC) Program confirmed the presence
of remaining impacted soils above the ISB Preliminary Health-Based Soil Remediation Goals
(Health-SRGs) and Protection of Groundwater SRGs (GW-SRGs). In addition, groundwater
impacts were detected above the NCAC 15A 2L Groundwater Quality Standards (2L Standards).
Mount Hope completed a Remedial Investigation for impacted site soils and submitted a Remedial
Investigation Report to the REC Program on August 6, 2010. The Remedial Investigation for

impacted groundwater was completed in 2012 and a follow-up Addendum Remedial Investigation
Report was submitted to the REC Program on September 4, 2012.

Proposed soil remedial activities were presented in AEI’s Soil Remedial Action Plan dated
August 2010. Remedial activities that were conducted included the excavation of approximately
1,105 tons of impacted soils from the former septic tank area and subsequent off-site Landfill
disposal. Confirmatory soil analytical data verified that soils were remediated to the cleanup
objectives. These soil cleanup activities and confirmatory analytical data are discussed in AEI’s
Soil Remediation Completion Report – Former Septic Tank dated November 2010.

Proposed groundwater Remedial Activities were presented in AEI’s Groundwater Remedial Action
Plan dated June 2014. Natural attenuation was selected as the remedial option for the Mount Hope
site. A discussion of the monitoring for natural attenuation is provided below.

2.0 NATURAL ATTENUATION MONITORING
With the remediation of soil and shallow groundwater impacting the source area
completed, it is anticipated that groundwater concentrations in the deeper aquifer associated with
the release at Mount Hope will naturally attenuate with time. Recent groundwater sampling has
identified five (5) compounds above 2L Standards, compounds include benzene, cis1,1-
dichloroethene (cis-DCE), tetrachloroethene (PCE), trichloroethene (TCE), and vinyl chloride
(VC). As discussed in the June 2014 Groundwater Remedial Action Plan (RAP), only cis-DCE
can be attributed to releases at the Mount Hope facility. Benzene, PCE, TCE, and VC are
considered background compounds originating from upgradient sources and not the responsibility
of Mount Hope to remediate.

During groundwater remedial action conducted in the 1990s, Mount Hope conducted
quarterly groundwater monitoring for three (3) years; therefore, monitoring for natural attenuation
began with annual groundwater sampling for the first year after the RAP approval and subsequent
years until concentrations of DCA and cis-DCE decrease to below 2L Standards.

The 2015 groundwater monitoring event included measuring water level in site wells,
collection for groundwater samples from deeper wells MW-4A, MW-11A, MW-14A, and MW-
15A and shallow wells MW-5, MW-6, and MW-13. Samples were analyzed for volatile organic
compounds (VOCs) by United States Environmental Protection Agency (USEPA) Method 8260.

2.1 Evaluation of Groundwater Flow
Prior to purging the designated monitoring wells to be sampled, static water levels were
measured in all existing monitoring wells. Monitoring well water level measurements are
summarized in Table 1. Shallow and bedrock groundwater potentiometric maps have been
constructed based on water table elevations calculated from static monitoring well water levels
measured on June 1, 2015 (Figures 2 and 3). Shallow groundwater flow is generally to the
southeast with an average horizontal gradient of 0.040 feet/foot. The deeper aquifer flow is to the
south and southeast at an approximate horizontal gradient of 0.029 feet/foot. The vertical hydraulic
gradients were calculated from measurements made on June 1, 2015 for well clusters MW-
4R/MW-4A, MW-14/MW-14A, and MW-16/MW-16A. Vertical gradients are summarized below:

Monitoring Well Cluster Gradient
(Feet/Foot) Direction
MW-4R/MW-4A 0.0335 Downward
MW-14/MW-14A 0.0088 Downward
MW-16/MW-16A -0.00001 Upward

The low vertical head gradient indicated that the groundwater flow is predominately
horizontal.

2.2 Monitoring Well Sampling and Analysis
On June 1, 2015, groundwater samples were collected for laboratory analysis from
designated monitoring wells.

Based upon measured monitoring well water levels, monitoring well depths, and known
casing diameters, the number of gallons of standing water in each monitoring well was calculated
to determine the required purge volume. Each monitoring well to be sampled was purged of
approximately three (3) static monitoring well casing volumes or until the monitoring well was
purged of all water. Monitoring well purging was performed using either an electric stainless steel
submersible pump (in monitoring wells MW-4A, MW-5, MW-11A, MW-14A, and MW-15A) or
dedicated bottom-loading bailers (in monitoring wells MW-6 and MW-13) attached to new nylon
cord. Groundwater samples were collected from monitoring wells MW-4A, MW-5, MW-11A,
MW-14A, and MW-15A using the submersible pump following each monitoring well evacuation.
Groundwater samples were collected from monitoring wells MW-6 and MW-13 using dedicated
bailers. Samples were carefully transferred from the sampling equipment into laboratory supplied
40 mL Volatile Organic Analysis (VOA) vials that were immediately placed in an insulated cooler
with ice following their collection. Monitoring well development, purging and sampling methods
were performed in accordance with the approved Standard Procedures/Technical Methods
included in Attachment B of AEI’s June 2014 Groundwater Remedial Action Plan.

2.3 Groundwater Analytical Results
GTA contracted Shealy Environmental Services in West Columbia South Carolina to
complete the required analysis for the 2015 sampling event. The groundwater samples were placed
in clean laboratory-provided containers, placed in a chilled cooler, and couriered to the laboratory
under chain of custody documentation to be analyzed for volatile organic compounds (VOCs) by
USEPA method 8260. A tabulated summary of the groundwater analytical results for the June
2015 monitoring event is presented in Table 2. Laboratory analytical reports and chain of custody
records are included in Attachment A. Historical groundwater analytical results from March 2009
to the present are presented in Table 3.

In the June 1, 2015 sampling event, five (5) target compounds were identified in monitoring
well samples at concentrations above the North Carolina Department of Environment and Natural
Resources (NCDENR) 15A NCAC 2L Groundwater Quality Standards (GQS) or interim standards
(2L Standards); compounds included benzene, Cis-DCE, PCE, TCE, and VC.

Analytical results from samples obtained from deeper off-site well MW-14A detected
concentrations of benzene at 1.20 µg/L, 1,1-DCA at 5.50 µg/L, 1,1-DCE at 3.30 µg/L, cis-DCE at
68.00 µg/L, methyl tert-butyl ether (MTBE) at 0.62 µg/L, methylene chloride at 0.52 µg/L, PCE

benzene, PCE, TCE and VC were detected at concentrations exceeding their respective 2L
standards of 1.00 µg/L, 0.70 µg/L, 3.00 µg/L, and 0.03 µg/L respectively.

Analytical results from samples obtained from deeper off-site well MW-15 detected
concentrations of 1,1-DCA at 2.60 µg/L, 1,1-DCE at 0.83 µg/L, cis-DCE at 30.00 µg/L, PCE at
1.10 µg/L, toluene at 0.90 µg/L, and TCE at 0.65 µg/L. Of the VOCs detected PCE was detected
at a concentrations exceeding its 2L standard of 0.70 µg/L.

3.0 SUMMARY
A comparison of the 2015 annual groundwater monitoring results with historical data for
the same monitoring wells shows that benzene continues to be detected in the deeper monitoring
wells above the 2L Standards while the shallow wells remain below the 2L Standard. This data
continues to suggest that benzene impacts may have originated from an up gradient off-site source.
With the exception of MW-13, cis-DCE concentrations have fallen below the 2L Standard of 70
µg/L. MW-13, which is located south east of the site (off-site) is suspected to be impacted by off-
site sources flowing toward the subject site. PCE and TCE concentrations detected in samples
obtained during this sampling event are also believed to be influenced by off-site sources. The VC
detected is believed to be the result of degradation of the compounds identified during the sampling
event and provide support that on-going natural attenuation is occurring at the site.

Mount Hope will conduct the 2016 annual groundwater monitoring event in the 3rd quarter of 2016.
