Carolina Concrete, Petroleum AST Incident No. 87717
11509 Reames Road
Charlotte, Mecklenburg County, North Carolina
S&ME Project No. 1354-05-687D
Dear Mr. McClain:
S&ME, Inc. (S&ME) submits this letter report of the recent groundwater sampling results
for the above referenced site. The report was prepared in general accordance with
S&ME's Proposal No. 1354-19139-08, dated February 6, 2008.
In summary, the results of the February 13 and May 12, 2008 sampling of the source area
monitor well MW-1 indicate levels of petroleum contaminants in the groundwater at
levels above the 15A NCAC 2L .0202 groundwater quality standards.
1. BACKGROUND
On November 28, 2006, S&ME submitted a Limited Comprehensive Site Assessment
(LCSA) related to the above ground diesel release at the site (Figure 1). The LCSA
included a summary of soil and groundwater assessment results performed to date, the
results of a water supply well receptor survey and recommendations for future activities.
The LCSA was submitted to Ms. Amber Lindon of the North Carolina Department of
Environment and Natural Resources (NCDENR) for her review. The results indicated
levels of one contaminant (C9-C22 Aromatics) at concentrations above the 15A NCAC
2L groundwater quality standards.
On December 5, 2006, Mr. Al Quarles of S&ME and Mr. Paul Hattenhauer of Culp
Elliott and Carpenter called Ms. Lindon to discuss the LCSA and the recommendations
presented in the LCSA. Ms. Lindon indicated that she agreed with the recommendations
of 1) abandoning three of the four monitor wells, and 2) quarterly monitoring of the
remaining monitor well (MW-1) located at the source area. The locations of the monitor

well MW-1 and the former above ground diesel storage tank are indicated on Figure 2.
Ms. Lindon approved the recommendations in a letter dated December 21, 2006, and
requested that reports of the quarterly monitoring be submitted in by June 30 and
December 31 of each year. During 2007, the regulatory oversight of non -UST petroleum
releases was transferred to the NCDENR, UST Section.
2. GROUNDWATER SAMPLING AND ANALYTICAL RESULTS
On February 13, 2008 and May 12, 2008, S&ME measured the depth to water from the
top of well casing prior to sampling with depths of 19.77 and 18.96 feet, respectively.
S&ME purged and sampled the well using a clean, disposable bailer. The sample was
submitted to Pace Analytical Services, Inc. (Pace), a state -certified laboratory, for
analysis of C9-C22 Aromatics using MADEP Method EPH/VPH.
A summary of laboratory results are provided in Table 1 and copies of the laboratory
reports are attached. The February and May 2008 concentrations of C9-C22 Aromatics
were 760 and 980 micrograms per liter (µg/L), respectively, compared to the 15A NCAC
2L .0202 groundwater quality standard of 210 µg/L.
3. CONCLUSIONS
The February and May 2008 sampling results indicate that petroleum levels continue to
exceed the 15A NCAC 2L .0202 groundwater quality standar. Thus, continued quarterly
monitoring is recommended.
If you have any questions regarding this report, or we may be of further assistance, please
call us at 704-523-4726.
Very truly yours,
