2.0 Site History .
. ...
S-K currently operates' hazardous materials storage facility. at 2320 Yadkin Avenue in Charlotte,
Mecklenburg County, North Carolina. The site' location is shown on'the attached Figure 1:.'The
facility performs collection, replacement; : accumulation and: storage of spent mineral spirits,
immersion cleaner, paint waste; . and dry-cleaning wastes as a service to: industrial maintenance,
automotive repair,. and,dry-cleaning businesses: Waste materials retrieved from .customers are .....
stored :in appropriate boxes, drums, :or aboveground storage: tanks (ASTs) at the: facility before
being shipped to one of S-K's -recycle centers or .disposal facilities. Where feasible, the recycled
product is returned to the: facility as ;reusable product for: distribution to customers. The facility
began operations on June 5, 1978,. -and currently maintains a Part B Resource Conservation and
Recovery Act (RCRA)permit for hazardous waste storage.
:. In the early 19809, prior to installation of the current waste mineral spirits management system, at
the facility, used mineral spirits: were placed into a 500-gallon underground storage tank -(UST)
and, then into a 10,0007gall6n capacity UST,: The 500=gallon_ UST provided in -line; solids settling
for the waste. mineral spirits prior.to-accumulation in the 10;000-gallon UST. The UST system.was ...
operated for a five-year eriod from 1980 until:itsremoval in August 1985. The waste mineral

investigation activities. SWMU-8.is the former 500-gallon waste mineral spirits settling tank and
SWMiJ-9 is the f6rmer:1.0,000-gallon waste, mineral spirits tank. Another 10,0007gallon mineral
spirits UST was located immediately adjacent to the waste I0,000-gallon tank and was used to
: store virgin mineral spirits product. The virgin mineral:spirits tank is not considered part of the .

On Ma 6 -201:1 a Groundwater- Sam lin and Analysis Plan SAP . and Corrective Measures
y. P g.... Y (, ).
Study: (CMS) were submitted for the, site.. Both submittals were. approved by NCDWM ina letter ....
dated: June 3, 2011. Periodic groundwater monitoring was initiated following the SAP approval.
The CMS recommended installation of a soil vapor extraction (SVE):system to remediate impacted
soil: and chemical:: injection to remediate impacted groundwater. Each of these remedial measures,
is discussed further below.
Injection was initially attempted using direct -'push technology in December 2011. However, the
initial in' ection was generally unsuccessful :due to the site geology and direct- ysh refusalde � ths.
J g. Y g. gY p .. p
Permanent injection wells were subsequently installed:and a second injection eventwas conducted
in March 2012: The injection fluids consisted of a mixture. of sodium persulfate (Klozur) and
hydrogen peroxide: The injection. was permitted by.NCDWR via Injection Permit WI0300181.
The results. of the injection activities were documented in the Semiannual Groundwater Monitoring
Report dated May . % 2012. Groundwater monitoring performed post- injection indicated
concentrations of VOCs and SVOCs reduced to.below Title 15A NCAC 2L .0202 Groundwater
Standards (2L Standards) within 18 months following: the injection :and remained below
2L Standards: over a three-year:time period from 2013 through 2016. Groundwater monitoring for
VOCs and SVOCs ceased after the March'2016 event since. no exceedances of 2L Standards had..
been detected for three years, which was the criteria for discontinuation.of monitoring detailed in
the approved GW SAP.:: However;" additional groundwater sampling events .for -sulfate were
performed in December 2016, March 2017, September 2017, and March 2018 at the request of the
NCDWR due to elevated sulfate concentrations associated with the persulfate injection.
An SVE pilot test was completedand proposed design specifications for the SVE :system were
-' submitted to NCDWM .for review in September 2011. The. SVE system wassubsequently
constructed and started in July 2012. The system included. extraction: of vapors from: two wells

10 Receptor Information .:
3.1 : Water Supply Wells
_I Several surveys for water: supply wells within 0.25 miles of the site have been performed, with :the
most recent survey in December 2017 as part of the RCRA permit renewal for the site. The
Mecklenburg: County on-line well information system previously reported a. private water supply
well approximately :800 feet. east of the site at 832 Woodside' Avenue. However, .on-line system
did not report this well in December 2017 and the. Charlotte -Mecklenburg Utilities .Department
- confirmed that this:.property is currently : connected to the :municipal water service. No other
�- possible water supply wells :have :been identified _ within 0.25 miles of the site. In addition,
Mecklenburg County Groundwater Well: Regulations do not allow permitting of new water supplyq.
-'' wells in: the: site vicinity. Atwater supply well location map is included as Figure 3.
a J.
- 3.2 Public Water Supply
Public water service is available, in the site, vicinity from Charlotte Mecklenburg. Utilities
-! Department.- Public water. is obtained from Lake Norman and Mountain Island Lake.: These
surface water bodies- are both located over: 5 miles northwest of the site.
- 3.3 Surface Water Bodies
q.
The: surface water body in closest proximity to the site is Little Sugar Creek, which is located :
r.
approximately 1;200 feet to the west. Little Sugar Creek is a Class C surface water body. Surface
water bodies in the site. vicinity are shown. on Figure 1.

4.0 Geolo:gy-and Hydrogeology
: 4.1: Site Geology:
According to the _Geologic Map of North Carolina, the site is located in'the Charlotte Belt of the
Piedmont Physiographic Province in south-centralNorth Carolina: The Piedmont area is underlain
by. a complex of metamorphic and igneous rocks covered by a veneer of unconsolidated sediments..
and: residual soils . derived from the .underlying rocks.. Specifically, the site is underlain : by
metamorphosed.: granitic bedrock : _which is inegacrystic, well foliated, and locally contains
hornblende.
- Based on soils encountered during recent and historical drilling operations, subsurface soils consist
primarily of silt with varying amounts of clay. and sand. Likely fill material was encountered in
the:area of the former UST pit, although.the exact depth of fill was difficult to discern. The'
:
transition from :unconsolidated soils -to c o mpetent bedrock is gradual and the depth: of refusal is
largely dependent on the type of drilling rig utilized.' During historical drilling operations, bedrock
refusal was encountered'at depths ranging from 8 feet below ground surface(ft bgs) to greater than
25 ft bgs... The. depth to bedrock generally increases from north to south across the site, which is
likely, reflective of grading conducted during:construction of the: on -site facility.
4.2 Site Hydrogeology _:
Nine 'Monitoring. wells were installed at the site during prior assessment activities. With the..
exception of.well MW-2D, the site monitoring wells are set''in unconsolidated soil ''partially
weathered rock, or shallow fractured bedrock, which are interconnected and can:reasonablybe
considered part. of the same aquifer zone. Well . MW=2D is a Type III well set in the deeper
competent bedrock aquifer zone. Well construction details are. summarized in Table 1. -
The depth to: groundwater measured in the monitoring well network historically ranges from
7.89 to 21.30 ft bgs, with typical depths on: the order of 15 to 20 ft bgs. Depth to groundwater data
are summarized, in Table 2. Based on historical depth to water measurements, the direction of

groundwater flow across. the site is towards .the north with soiree: variability, to the: north-northeast
and north-northwest. A groundwater elevation contour map based on the latest site -wide gauging
event is included: as Figure 5. Based on a review of Historical- groundwater elevation data, the
horizontal hydraulic gradient across the site ranges :from 0.01 to 0:04: feet per foot (ft/ft)' with an

5.0 Recent Assessment Activities
a _..
This section documents soil sampling performed in December 2017 and March 2018, which was ..
not documented: in prior reports submitted for .the -site. On December l8, 2017, one soil: boring
was, advanced at the location of prior soil, boring B-6. A core, drill -was used to :core through the
concrete at the grouri surface then the boring.was advanced using a decontaminated hand auger.
Two soil samples were .collected from the boring at depths of.5 and 10 ft bgs.. The samples were
collected in laboratory supplied containers; :placed in an ice -filled cooler, then submitted to Pace
_.
Analytical, Services, LLC -.(Puce). The samples were analyzed:: for total . VOCs: by
EPA Method 8260, _,total,: SVOCs by -,EPA, Method 8270, Synthetic Precipitation Leaching
Procedure: (SPLP) VOCs by EPA Method 8260, and SPLP SVOCs by EPA Method 8270. ...
The laboratory results for the December 2017 soil: sampling indicated elevated detection limits
which undermined the usefulness of the data:: The results also indicated some data flag s related: to
quality control _samples which suggested concerns:regardingthe validity of the data (analyte
recovery in laboratory control sample outside quality control limits, matrix spike.rec.overy outside
laboratory control limits; matrix spike recovery exceeded quality control limits; and surrogate
recovery outside laboratory. control limits). Therefore',: another soil sampling event wm.performed
on March 26, 2018.. Sampling locations :and methodology for the March 2018: sampling event
were similar: to the December 2017 sampling event, except samples were submitted to
Test -America Laboratories, Inc. (Test America) for laboratory: analysis.
H&H reviewed the Test America laboratory report to confirm the data quality. Concentrations. of..
methylene chloride were detected in both the laboratory method blank and the SPLP samples. As
such; the methylene chloride detections should be considered suspect. Some other data flags were
reported,. but- these flags do notsignificantly impact the data :presented in this report. The
sw
laboratory analytical reports for the December 2017 and March 2018 soil sampling results are .. .
included in Appendix B.
Comparison of the March 2018 soil sampling results to historical results indicates increases in
concentrations for some constituents. H&H .attributes the increases to inhorriogeneity in

contamination does not pose a risk in the:future. S-K owns the. site property and'is agreeable: to
filing of LURs on the deed for the property.
Following concurrence from NCDWM and: NCDWR.re'garding the data .presented in this report;
H&H recommends drafting: of a LUR document 'and associated survey: plat, completion of public
. .
notification activities;, and filing of the LUR:document and survey plat with the register of deeds.
Upon completion of these activities, H&H recommends that NCDEQ issue no further action. status

Note: The 2L Standards are shown for convenience. However, if the 2L Standards are the target groundwater concentration at the POE they
must be manually entered in column F. This is to allow for situations where the target groundwater concentration at the POE may be values other
than 2L Standards (vapor intrusion screening levels for example).
