Inspection Summary:
Met with Nick Miller,Arcadis G&M of North Carolina, Inc.(ARCADIS) and Todd Mixon, subcontractor for ARCADIS. Walked
the site and discussed the remediation system. According to Mr. Miller, the system operated very well. The only problem
was freezing of lines during cold weather. The inspection reflects compliance with the permit. The system was run twice:
Phase I: November 11, 2019 to February 27, 2020
Phase II: June 22, 2020 to September 24, 2020
Review of the data indicated the system was effective in removing dissolved phase concentrations of benezene and
napthalene to concentrations below the NCAC 2L Standards in three monitoring wells where there were previous 2L
exceedances. The influent and effluent data also indicated the system reduced volatile constituents to concentrations below
the laboratory detection limits.
