Subject: Soil Stockpile Sampling Analytical Results
Site: Almont Shipping II
19 & 41 Harnett Street, Wilmington, North Carolina (New Hanover County
Parcels No. R04716-001-026-000 & R04712-002-001-000)
NCBP No. 23080-19-065
Dear Ms. Goodwin:
On behalf of Wilmington Waterfront Property Owner, LLC (the Prospective Developer [PD]),
Geosyntec Consultants of NC, P.C. (Geosyntec) is providing this data package to present the
analytical results for soil stockpile sampling located on the 41 Harnett Street portion of the Almont
Shipping II Brownfields Property (NCBP No. 23080-19-065). The soil stockpile was generated
during development of the paved parking lot located on the 19 Harnett Street property. This soil
needs to be relocated to accommodate soil and groundwater testing and future redevelopment. A
27 March 2020 Work Plan for Stockpile Sampling and Relocation was approved by North Carolina
Department of Environmental Quality (NCDEQ) on 30 March 2020. The sampling was performed
in accordance with the Work Plan on 7 April 2020.
Two composite samples, each consisting of five (5) aliquots from five (5) separate soil borings,
were collected and analyzed for semi -volatile organic compounds (SVOCs) by EPA Method 8270,
organochlorine pesticides by EPA Method 8081, the eight (8) Resource Conservation and
Recovery Action (RCRA) metals by EPA Method 6010 and 7471, and hexavalent chromium by
EPA Method 7199. Two grab samples from two of the aliquots was also analyzed for volatile
organic compounds (VOCs) by EPA Method 8260. Aliquot locations are shown on Figure 1. The
results (detections only) are shown in the attached Table 1. The laboratory analytical report, which
includes a trip blank for VOCs and Level `B" Quality Control (QC), is provided in Attachment
A.
Only one metal (arsenic) and two polynuclear aromatic hydrocarbons (PAHs) were detected above
a default direct exposure NCDEQ Preliminary Soil Remediation Goals (PSRG). The detected
concentrations are consistent with typical background and/or anthropogenic levels in urban soils.
To further assess the risk to exposure to these soils, Geosyntec used the NCDEQ Risk Calculator
(NCDEQ, December 2019) to evaluate cumulative cancer and non -cancer risks to human health

using the collected analytical data. The risk evaluation was conducted in general accordance with
the Revised Technical Guidance for Risk -Based Environmental Remediation of Sites (Risk -Based
Guidance) (NCDEQ, 2020). The maximum detected concentration from each chemical from the
2020 sampling event was input into the calculator as a conservative measure and per the Risk -
Based Guidance. The results of the screening do not indicate unacceptable cumulative health
effects (cancer and non -cancer) for the receptors considered, including residential. The direct
output from the NCDEQ Risk Calculator results is presented in Attachment B.
Geosyntec will notify NCDEQ when another Brownfields site or facility is identified for relocation
of the soil stockpile. The export location will be approved, in writing, by NCDEQ prior to soil
relocation. We look forward to your review of these results. Please do not hesitate to contact
Kaitlyn Rhonehouse (910-726-3652 or [e-mail]) if you have any questions.
Sincerely,

2. U indicates analyte was not detected above the method detection limit
3. J indicates an estimated value
4. Analyte detections are identified in bold
5. Analytes that were not detected (i.e. concentrations that were below the laboratory Method Detection Limit [MDLJ), but
exceeded a PSRG are identified in italics
6. mg/kg indicates milligrams per kilogram
7. NA indicates PSRG not established
8. Only analytes detected in one or more samples are included in this table; PAHs and metal concentrations are believed to be
consistent with naturally occuring background and/or anthropogenic concentrations. Refer to the Risk Calculator output related to
the overall risk evaluation for detected constituents.

10. If multiple screening criteria are exceeded, the highlight corresponds to the highest value screening
criteria exceedance
11. Chlordane is calculated as the summation of alpha -Chlordane and gamma -Chlordane.
12. Assumed chromium (1I1) equals to total chromium detection for conservative reason, because chromium (VI)
is non -detect.
