Soil Excavation Report
Swans Run Road Site
7501 Swans Run Road
Charlotte, Mecklenburg County, North Carolina
ECS Project No. 49:13239
April 1, 2021
1.0 PROJECT INFORMATION
The site is located at 7501 Swans Run Road in Charlotte, Mecklenburg County, North Carolina (Figures 1
and 2). ECS previously conducted residential heating oil underground storage tank (UST) removal services
at the site in July 2016 and over -excavation of the former UST area in August 2016, as reported in the UST
Closure And Initial Abatement Action Report (ECS Project No. 49-2115-A), dated September 23, 2016. Soil
samples were collected beneath the UST during removal activities and from the side walls of the over -
excavation. C9-C18 Aliphatics and C11-C22 Aromatics were detected in over -excavation soil sample EW-1
at concentrations greater than their respective Soil -to -Groundwater and Residential Maximum Soil
Contaminant Concentrations (MSCCs). The approximate area of the previous excavation and sample
locations are indicated on Figure 3. Further excavation in this direction was prevented by the presence of
the site residential structure. Additional over -excavation samples did not exhibit concentrations of
compounds of concern at greater than the laboratory method reporting limits. ECS recommended in the
above referenced report that when the site residential structure was removed from the site prior to
redevelopment that the remaining contaminated soil be excavated and removed from the site.
ECS was informed by Chelsea Building Group that the site structures had been removed from the site and
could now proceed with the additional over -excavation in the area of former soil sample location EW-1.
2.0 SCOPE OF SERVICES
The scope of services consisted of excavating the area previously inaccessible where former soil sample
EW-1 was previously collected, collecting a post excavation soil sample of the side wall, submit for
laboratory analysis, and preparation of this report. Soil excavation and sampling activities were conducted
on March 22, 2021.
3.0 SOIL EXCAVATION AND SAMPLING ACTIVITIES
On March 19, 2021, ECS personnel mobilized to the site in order to locate the previous excavation area as the
former site structures had been removed. ECS personnel utilized previous figures and a measuring wheel to
locate the approximate previous excavation area. It was noted during the initial site visit that some excavation
had already been conducted in this area for the creation of a drainage pond.
On March 22, 2021, ECS personnel met with the excavation contractor (Eddie Massey) onsite to begin
excavation activities. It was noted that the area of the previous limits of the excavation in the previous
sample EW-1 location had been excavated approximately six feet below ground surface for the creation
of the drainage pond. The excavation contractor excavated an area approximately two feet wide by
approximately an additional eight feet deep. A tracked excavator was used to complete the excavation
activities. ECS screened the soil removed from the excavation with a Photo Ionization Device (PID) for the
presence of organic vapors. The PID readings ranged from 0.0 to 0.1 parts per million. In addition, no
odors or other evidence of contaminated soil was noted. As no contaminated soil was noted in the area
of the excavation, no soil was removed for the site for disposal.
Following the excavation activities and screening of the soils, the excavation contractor assisted ECS with

the collection of a soil sample (SW-1) from the side wall of the new excavation at a depth of approximately
12 to 14 feet below original grade. The sample was placed into laboratory prepared glass containers.
After being filled, the sample containers were labeled and placed into a cooler containing ice to maintain
the samples at a temperature of approximately four degrees Celsius. The samples were transported to
Pace Analytical Services, LLC (Pace), a North Carolina certified laboratory located in Huntersville, North
Carolina to be analyzed for volatile organic compounds (VOCs) by EPA Method 8260, semi -volatile organic
compounds (SVOCs) by EPA Method 8270, and volatile and extractable petroleum hydrocarbons
(VPH/EPH) by Massachusetts Department of Environmental Protection Methods. The samples were
transported to the laboratory under chain of custody. A copy of the Chain of Custody Record is included
in Appendix A.
4.0 LABORATORY ANALYTICAL RESULTS
Review of the laboratory analytical results indicated toluene at a concentration greater than the
laboratory method reporting limit in the SW-1 soil sample, but less than its Soil -to -Groundwater,
Residential, and Commercial/Industrial MSCCs. No additional compounds were detected in the SW-1 soil
sample. The current and historical soil analytical results are summarized in Table 1. Laboratory analytical
data sheets are included in Appendix A.
5.0 CONCLUSIONS
Based on the results of the sampling conducted at the site on Mach 22, 2021, soil contamination is not
apparent in the area of the former UST at 7501 Swans Run Road location.
6.0 RECOMMENDATIONS
Based on the results of the soil excavation and sampling activities, ECS recommends the following:
• ECS recommends that a copy of this report be maintained for your records.
• ECS does not recommend additional soil sampling at this site.
• ECS recommends submitting this report, and the UST Closure and Initial Abatement Action Report
dated September 23, 2016, to the NCDEQ Mooresville Regional Office, Division of Waste
Management, UST Section for their review and determination for a status of No Further Action
for the site.
7.0 QUALIFICATIONS OF REPORT
The activities and evaluative approaches used in this assessment are consistent with those normally
employed in environmental assessment projects of this type. Our evaluation of site conditions has been
based on our understanding of the site project information and the data obtained during our field
activities. This report was prepared for the express use of Chelsea Building Group. Use of this report by
other individuals or companies implies their acceptance of the General Conditions of Service of the
original contract.

Subject: RE: [External] NCDEQ Report
Good Morning Joe,
Ron forwarded me the Swans Run Road Soil Excavation Report. I handle home heating oil usts for Mecklenburg
County. The report does not have a licensed geologist or professional engineer's seal. The soil report also
recommended that UST Closure and Initial Abatement Action Report dated September 23, 2016 be submitted for review
as well. Please email a copy of the 2016 UST Closure/Initial Abatement reports as well as a sealed/stamped copy of the
Soil Excavation Report when available for review.
Have a wonderful day,
Trudy
