1.0 EXECUTIVE SUMMARY

SUMMIT Engineering, Laboratory and Testing, P.C. (SUMMIT) personnel conducted a Limited
Phase II ESA of the Thomas Road Site, based on environmental concerns identified during the
completion of due diligence activities for the subject site. The reported concerns were in connection
with a former Construction and Land Clearing Debris landfill operated on the subject property.
Field work was completed by SUMMIT on July 1, 2018 and July 2, 2018.

In summary, three (3) groundwater samples were attempted to be collected from the subject site to
identify if the observed former construction and land clearing debris landfill on-site impacted the
environmental quality of the groundwater at the subject site. TMW-2 did not yield groundwater for
sampling at the time of this assessment. All collected groundwater samples were analyzed for the
presence of VOCs and Total RCRA Metals (dissolved phase).

Acetone was the only detection in the collected groundwater samples. Acetone was detected well
below the North Carolina Groundwater standards (NC 2L) and is considered a laboratory artifact.
No other detections were reported.

Based on the results of this Limited Phase II ESA, SUMMIT concludes that the identified former
construction and land clearing debris landfill has not significantly impacted the subject site at the
time of this report. Therefore, SUMMIT recommends no further assessment.

2.0 INTRODUCTION
2.1. PURPOSE

SUMMIT was retained by Century Communities, to perform a Limited Phase II ESA of the Thomas
Road Site, located at 14900 Thomas Road, Charlotte, Mecklenburg County, North Carolina
(Mecklenburg Tax IDs: 21703102 & 21703155). The Limited Phase II ESA was requested in order
to assess environmental concerns adjacent to a construction and land clearing debris landfill area
located on the subject property. The landfill was reportedly operated from 1985 to 1987 by Blythe
Industries. This report presents the results of our Limited Phase II ESA of the Thomas Road Site. .

2.2. SITE DESCRIPTION

The site is irregular in shape and was noted to be comprised of two (2) parcels (Mecklenburg Tax
IDs: 21703102 & 21703155) totaling approximately 38.75 acres in area. The subject site is
primarily undeveloped and wooded, with a vacant residential home located near Thomas Road. The
landfill area was reported by the client and identified in previous reports to be located along the
southern site boundary. The site is accessible from Thomas Road to the east of the site. Refer to the
Sampling Location Map shown in Figure 2 of Appendix I for the location of the subject property.

2.3. ASSESSMENT HISTORY

SUMMIT was provided a Phase I ESA completed by others for the subject property, dated
December 1, 2016. The report did not identify the presence of RECs in connection with the site.
The report identifies the former landfill on the site. According to their findings, sampling of four 94)
water supply wells near the site by Mecklenburg County did not identify groundwater
contamination. Test pits performed as part of a geotechnical investigation identified only landscape
debris, trash and other inert materials (brick, concrete, etc.). Since the test pits did not contain
hazardous materials and the groundwater samples did not identify contaminants, the former
construction landfill was considered a De Minimus condition at the time of the December 1, 2016
report.

No other site specific or surrounding area assessment history is known at the time of this report.

2.4. WORK PLAN OBJECTIVES

SUMMIT proposed to perform a Limited Phase II ESA according to our understanding of the most
likely potential for impact, in general accordance with ASTM E1903, and in accordance with the
USEPA Field Branches Quality System and Technical Procedures Manual. The proposed scope of
services included the installation and sampling of three (3) temporary monitoring wells in order to
assess the soil and groundwater quality adjacent to the debris area on the site. The proposed
sampling locations were placed in locations and in areas that may help identify migrating
contaminants from the area of concern. All samples collected were scheduled to be relinquished to a
NC certified laboratory for analysis. Collected groundwater samples were submitted for of Volatile
Organic Compounds by EPA method 8260 and for dissolved RCRA Metals by EPA method 6010.

3.0 PROPERTY SETTING

3.1. TOPOGRAPHIC SETTING

The United States Geological Survey (USGS) Lake Wylie topographic quadrangle map was
reviewed for this report. The elevation of the subject property ranges from approximately 740 feet
above Mean Sea Level (MSL) to 640 msl. The contour lines indicate the general direction of
downward slope to west towards an unnamed tributary of Torrence Branch. The Torrence Branch
flows southwest and enters Lake Wylie. Refer to Figure 1 in Appendix I of this report.

3.2. GEOLOGIC SETTING

The property is located in Mecklenburg County, North Carolina, which is located in the south central
Piedmont Physiographic Province. The Piedmont Province generally consists of well-rounded hills
and ridges which are dissected by a well-developed system of draws and streams. The Piedmont
Province is predominantly underlain by metamorphic rock (formed by heat, pressure and/or
chemical action) and igneous rock (formed directly from molten material) which were initially
formed during the Precambrian and Paleozoic eras. The volcanic and sedimentary rocks deposited
in the Piedmont Province during the Precambrian era were the host from the metamorphism and
were changed to gneiss and schist. The more recent Paleozoic era had periods of igneous
emplacement, with at least episodes of regional metamorphism resulting in the majority of the rock
types seen today.

The topography and relief of the Piedmont Province has developed from differential weathering of
the igneous and metamorphic rock. Ridges and hills have been developed on the more easily
weathered and erodible rock. Because of the continued chemical and physical weathering, the rocks
in the Piedmont Province are now generally covered with a mantle of soil that has weathered in
place from the parent bedrock. These soils vary in thickness and are referred to as residuum or
residual soils. The residuum is typically finer grained and has higher clay content near the surface
because of the advanced weathering. Similarly, the soils typically become coarser grained with

E:\Project Forms\Projects\4319.514 Thomas Road Site - Phase I ESA\Limited Phase II ESA\4319.514 Thomas Road Site - Phase II ESA.doc 5
increasing depth because of decreased weathering. As the weathering decreases, the residual soils
generally retain the overall appearance, texture, gradation and foliations of the parent rock.

3.3. HYDROLOGIC SETTING

Based on a review of the United States Geological Survey (USGS) Lake Wylie topographic
quadrangle map, the inferred groundwater flow direction based on topography appears to be to the
west towards the unnamed tributary of Torrence Branch. Refer to Figure 1 in Appendix I for a
topographic map for the subject property.

4.0 SUMMARY OF FIELD ACTIVITIES

4.1. DRILLING ACTIVITES AND METHODS

On July 1, 2018, SUMMIT personnel conducted the temporary monitoring well installation scope
of the Limited Phase II ESA. The proposed temporary monitoring well (TMW) locations were
placed in locations and in areas that may help identify migrating contaminants from the identified
dump area on-site. The locations of the TMW locations can be viewed on the attached Sampling
Location Map, Figure 2, in appendix I.

SUMMIT utilized a CME Hollow Stem Auger drill rig to complete the soil borings and TMW
installation. At each location, a boring was advanced to 50 feet below ground surface (bgs) or
refusal. At termination depths, the TMWs were constructed within the HSA drill string. The TMWs
were constructed with solid riser and 20 feet of 2-inch Schedule 40 PVC 0.01-inch slotted well
screen encased in #3 filter sand from the base of the boring to approximately 2 feet above the well
screen. A 2 feet hydrated bentonite seal was pace on top of the well filter sand pack.

Each boring typically encountered tan/orange fine to medium grained sandy silts. Soil cuttings
generated during TMW installation were spread on-site.

TMW-1 was completed to at total depth of 48 ft bgs. TMW-2 was completed to a total depth of 40 ft
bgs. TMW-3 was completed to a total depth of 42.5 ft bgs.

Groundwater was encountered in TMW-1 and TMW-3. Depth to water (DTW) ranged from 47.5 ft
bgs to 42 ft bgs in the TMWs 24 hours after installation. Due to low groundwater yields, the TMWs
were not developed at the time of installation.

Upon completion of the drilling activities, the drilling equipment was decontaminated by the well
driller by use of a steam cleaner or Alconox and tap water wash, tap water rinse, isopropanol rinse
(sampling equipment), and deionized water rinse. Decontamination of the drilling equipment was

performed prior to starting drilling activities, and upon the completion of drilling activities at each
boring/well location.

4.2. SAMPLING

Groundwater was sampled from the installed TMWs on July 2, 2018, following a minimum 24 hour
equilibrium period after well installation. Groundwater was not encountered in TMW-2 at the time
of sampling.

Samples were collected utilizing new disposable bailers. Groundwater samples were containerized
in laboratory provided vials and containers, placed on ice and transported to the laboratory for
analysis. All groundwater samples were analyzed for Volatile Organic Compounds by EPA method
8260 and for RCRA Metals by EPA method 6010. Based on the turbid status of the groundwater
collected from TMW-2 and TMW-3, SUMMIT collected RCRA Metals in lab provided
unpreserved vials for the analysis of Dissolved RCRA Metals. Dissolved metal analysis utilizes
filtration to removed suspended sediment from a groundwater specimen in order to analyze only the
dissolved phase RCRA Metals. The dissolved metal analysis was chosen in order to prevent false
positives that may result from analysis of sediment laden samples.

4.3. PACKING AND SHIPMENT

Upon securing the samples in laboratory provided containers, the vial and jar lids were tightly
fastened, and the jars encapsulated in shock-resistant plastic bags. The samples and ice were double-
bagged in large plastic bags, tied off with rubber bands, and packed into a cooler. The samples were
delivered to Shealy Environmental Services, Inc, in West Columbia, SC. The vials and jars used for
the collection of the samples at this site were prepared by Shealy, and were pre-labeled and
contained analyte-appropriate preservatives. A listing of the preservatives in the sample containers
utilized for the collection of the samples at this site are cataloged in the Chain-Of-Custody record,
attached in Appendix III of this report. The secured samples were relinquished to laboratory on July
3, 2018 for laboratory analysis.

5.0 SUMMARY OF LABORATORY ANALYSIS

All samples were relinquished to Shealy Environmental Services on July 3, 2018 for the prescribe
analysis. Table 1.0 in Appendix II of this report summarizes all detections. The analytical detections
are summarized below:

• Acetone was detected in groundwater collected from TMW-1 at a concentration of 24 ug/L,
below the North Carolina Groundwater Standard of 6,000 ug/L.

No other detections were identified in the laboratory analysis.

6.0 FINDINGS & CONCLUSIONS

In summary, three (3) groundwater samples were attempted to be collected from the subject site to
identify if the observed former construction and land clearing debris landfill on-site impacted the
environmental quality of the groundwater at the subject site. TMW-2 did not yield groundwater for
sampling at the time of this assessment. All collected groundwater samples were analyzed for the
presence of VOCs and Total RCRA Metals (dissolved phase).

Acetone was the only detection in the collected groundwater samples. Acetone was detected well
below the North Carolina Groundwater standards (NC 2L) and is considered a laboratory artifact.
No other detections were reported.

Based on the results of this Limited Phase II ESA, SUMMIT concludes that the identified former
construction and land clearing debris landfill has not significantly impacted the subject site at the
time of this report. Therefore, SUMMIT recommends no further assessment.
