RE: Remedial Action Quarterly Progress Report
Second Quarter 2006
REC Program — DWM No. 99-SF-188
Former Pelton and Crane Facility, Charlotte, North Carolina
Dear Mr. Caulk:
In accordance with 15A NCAC 13C.0306(o), Advanced GeoServices Corp. (AGC), on behalf of
Siemens Medical Solutions USA Inca (SMS), submits this Remedial Action Quarterly Progress
Report. This report describes the activities at the Former Pelton and Crane Site (Figure 1)
between April 1, 2006 and June 30, 2006, and the activities scheduled for the upcoming three
months. A construction summary of the monitoring wells, injection wells, and piezometers are
described in Table 1. Monitoring and injection well locations are shown on Figure 2. The
laboratory data and validation reports are provided in Attachment A.
1. Activities Performed
The third process monitoring groundwater sampling event was performed
in June 2006 (i.e., 300 days post -injection). The sampling was performed
in accordance with Table 6-4 in the Groundwater Remedial Action
Engineering Design Report and the UIC permit.
Soil excavation and removal activities were performed in May and June
2006. for the Western Baghouse, North Parking Lot, Transformer, and
Unnamed Tributary areas. The progress of the soil removal as of June 30,
2006 is shown on Plate 1.
• Confirmation soil sampling was performed in accordance with the
Confirmation Sampling Plan in the Appendix H.2 of the Remedial Action
Plan, dated October 21, 2004 with the following exceptions. In the
Western Baghouse Area, the Confirmation Sampling Plan required only
:;;, • one sample per sidewall and one bottom sample for the entire area based
on the size of the area. However, AGC collected sidewall and bottom

samples at the end of each day of excavation to facilitate the
removal/restoration process. This resulted in an increased number of
confirmation samples being collected than the minimum number required.
The same approach was used in the North Parking Lot Area..
Confirmation soil sampling results for complete removal areas are shown
on Table 2.
2. Performance Evaluation
Total organic carbon (TOC) concentrations, a key indicator for evaluating
the horizontal and vertical limits of SRSTM, in the shallow groundwater
remain three orders of magnitude above the baseline conditions
(approximately 2 mg/L) within 50 feet down -gradient of the injection
wells but have continued to slowly decrease since the initial injection (see
Table 3). TOC concentration in the shallow groundwater further down -
gradient and the deep groundwater zone in the injection area remain
unchanged from the baseline conditions.
• Dissolved oxygen (DO) levels remained below 1 mg/L1 (see Table 3) in
all the monitoring wells (MW-1, MW-38, MW-40, and MW-41) near (i.e.,
within 50-feet down -gradient) the Phase I injection zone, except MW-18.
These results are consistent with the March 2006 data. The DO levels in
monitoring wells. greater than 50 feet down -gradient (i.e., MW-42, MW-
43 and MW-45) decreased back to below 1 mg/L, except for MW-44.
These concentrations are consistent with the. decrease in DO levels
observed in the up -gradient well MW-39.
The oxygen/reduction potential (ORP) was consistent with the March
2006 results and remains conducive to anaerobic biodegradation (see.
Table 3).
The pH results were consistent with the historic results (see Table 3).
Most wells in the shallow bedrock remain within the pH range considered
conducive to anaerobic biodegradation.
The monitored natural attenuation (MNA) parameters (see Tables 3 and 4)
continue to show strong evidence for biodegradation occurring in the
shallow groundwater within 50. feet down -gradient of the injection zone.
1 Dissolved oxygen levels above 1 mg/L are considered not condusive to anaerobic biodegradation of chlorinated
aliphatic hydrocarbons such as TCE.

• Trichloroethene (TCE), 1,1- Dichloroethene (11DCE), 1,2-Dichlorothene
(12DCE), and Vinyl Chloride (VC) continue to be the predominant VOCs
detected at the Site (see Table 5). The concentrations in June 2006
continue to decrease in wells MW-1 and MW-40 (25 ft down -gradient of
injection zone), wells MW-412 and MW-18 (50 ft down -gradient of
injection zone), and well MW-42 (75 ft down -gradient of injection zone).
• In summary, based on an overall assessment of the field data and
groundwater chemical data, the injection of SRSTM appears to be
promoting the biodegradation of the chlorinated aliphatic hydrocarbons in
the shallow groundwater within 50 to 75 feet down -gradient of the
injection wells. Continued monitoring will help determine the
effectiveness of the remedial system outside of the -initial injection area.
• Confirmatory soil samples collected from the individual soil removal areas
required vertical and horizontal expansion of the removal areas.
• Approximately 16 tons of hazardous soil was excavated and sent to
CycleChem's disposal facility in Lewisberry, Pennsylvania.
• Approximately 2,400 tons of non -hazardous soil was excavated and sent
to Allied Waste's Charlotte Motor Speedway landfill in Charlotte, North
Carolina.
3. Difficulties Encountered
• Due to the extended time to complete the soil removal activities. Water
from heavy rains in late June collected in the excavation areas and delayed
soil removal.
4. Corrective Actions Taken
• Two containers were mobilized to the site to temporarily store water in the
excavations (;:--10,000 gallons) until disposal could be arranged. Water
quality samples :collected indicated the water was not a characteristic
hazardous waste (see Table 6). Preliminary discussions with Charlotte
Mecklenburg Utilities, Environmental Management, System Protection
Division indicate a one-time discharge of the water to the sanitary sewer
maybe allowed.
2 TCE concentration is MW-41 have been below detection for three quarters. However, the detection limit has been
elevated due to laboratory dilutions.

5. Activities Scheduled for Upcoming Three Months
• Continue evaluation and performance of post -injection groundwater
monitoring.
Continue discussion regarding land use restrictions.
• Complete soil removal activities for the Western Baghouse Area,
Unnamed Tributary, Transformer Area and the North Parking Lot.

Detection Limit (DL) - The lowest -concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions.
U = Undetected at or below the detection limit

UJ = Undetected, detection limit is qualified as estimated
E = Concentration exceeded the instrument's calibration range, concentration reported is estimated
R = The value reported has been rejected due to the laboratory exceeding the method holding time
mg/L = milligrams per liter
µg/L = micrograms per liter
NR = not recorded due to instrument malfunction
1. VOE injection was performed in early August 2005
