RE: Report of Soil Assessment – Leachate Release - May 2024
City of Albemarle Landfill
Permit #8401-MSWLF-1999/8401-CDLF-1997
City of Albemarle
FID 1883155

Dear Mr. Preslar:

The Solid Waste Section (Section) has reviewed the Report of Soil Assessment – Leachate Release
May 2024 (FID 1883149) submitted on behalf of The City of Albemarle by Bunnell Lammons
Engineering, Inc. (BLE). The soil assessment was conducted in accordance with the plan approved
by the Section on May 14th, 2024.

At the conclusion of the force main relocation project, it was returned to service and
approximately 30 gallons of leachate flowed from the top of the manhole into a 4’ by 7’ trench.
Leachate was removed using a vacuum truck and impacted soil was also removed and disposed
of at the landfill. BLE collected a background soil sample (SA-4) from the spoils pile generated by
the trench excavation. A compliance soil sample (SA-6) was collected from the bottom of the
trench after impacted soil was removed. The soil samples were analyzed for: Appendix I
constituents, 1,4-dioxane, total phosphorus, sulfate, nitrate, and pH. Analytical results were
compared to the Preliminary Soil Remediation Goals (PSRGs). There were no reported detections
of volatile organic compounds or 1,4-dioxane in either soil sample. Total arsenic and total

chromium exceeded the PSRGs at similar concentrations in both soil samples. There were no
additional metal constituents reported at concentrations exceeding the PSRGs. Based on the
assessment results, BLE concluded that the remaining soil in the area of concern was not
impacted by the leachate release.

The Section agrees with BLE’s, conclusion and additional assessment related to the leachate
release in not required. Please contact me at 919-707-8288 or [e-mail] if you have
any questions or concerns regarding this correspondence. Thank you in advance for your
cooperation in this matter.

Sincerely,
