Monthly Progress Report No. 68
January 1999
This report summarizes Remedial Action and Downgradient Groundwater act1v11tes for the
Geigy Chemical Corporation Site during the given period. This report is submitted in accordance
with Section XI, Paragraph 29 of the Consent Decree.
l. ACTIONS TAKEN TOW ARDS COMPLIANCE WITH THE CONSENT DECREE
Remedial Action
• Continued operation of the groundwater extraction and treatment system during the report
period.
• Conducted the monthly site inspection on January 20th to verify system performance. The
system maintained continuous unattended operation during the report period and has treated
16,806,470 gallons since start-up.
• Conducted treatment system monitoring as currently required by the Site Groundwater
Remediation Permit and O&M Manual.
• The jet pump serving well PW-4S ( one of the surficial aquifer extraction wells used for ma~s
reduction) was replaced and the well was put back into service.
• The piping on one of the two water transfer pumps in the treatment building developed a
minor leak during the monthly inspection period. As a precaution, the pump was temporarily
taken out of service until the February monthly inspection, when materials needed for piping
repair will be available. This action had no effect on the operation of the system (i.e., the two
pumps normally alternate in operation, thereby allowing one pump to be taken off line for
servicing without interrupting treatment).
Downgradient RA WP
• Continued preparation of the third event, fourth quarter 1998 downgradient area monitoring
report.
• Conducted the fourth quarterly downgradient area monitoring event, including:
• Collection of comprehensive water-level measurements from downgradient area
monitoring wells, piezometers and stream staff gauges, and select facility property wells ..
• Collection of 10 stream surface water and sediment samples along McFarland's Branch,
Ray's Mill Creek and Aberdeen Creek at the monitoring locations described in the
RAWP.
• Collection of groundwater samples from 23 of the 26 wells included in the downgradient
area monitoring network.
; • •
2. RESULTS OF SAMPLING. TESTS AND OTHER DATA

RE: System Performance Summary and
Second Quarter 1997 Analytical Results
Geigy Chemical Corporation Site
Aberdeen, North Carolina
Dear Giezelle:
AUG 111997
SUPERFUND SECTION
VIA FEDERAL EXPRESS
Please find enclosed the Site performance monitoring and system operating report, which
includes:
• groundwater extraction and treatment system performance summary (Table I);
• baseline monitoring event analytical results summary table (Table 2) and laboratory data
report (Attachment A); and
• monitoring requirements summary table (Table 3).
The system continues to perform as designed. As noted in the May 6, 1997 baseline monitoring
event analytical report, trend graphs will be developed to facilitate review of future performance
monitoring and system operating reports. An indicator compound will be selected for tracking
purposes once a minimum of four quarters of monitoring data have been obtained. Concentration
trend graphs for all pesticides on the performance standards list will be prepared for all indicator
wells as part of the five-year remedy review.
In addition to the monitoring requirements summarized in Table 3, the Companies also collected
groundwater samples from each of the seven extraction wells during the second quarter 1997
monitoring event. These samples were obtained to compare pesticide and TCE concentrations in
the extraction wells between system start-up and current conditions. Analytical results of these
• •
samples are included for information purposes. Additional extraction well samples, if any, will be
collected as needed by the Companies to assess system performance.
One copy of this letter report has been sent directly to Randy McElveen ofNCDEHNR and Tim
Eggert ofCDM. If you require additional copies of the enclosed materials, or have any questions
about this information, please contact me at [phone].

Dear Mr. Hilliard:
Attached are the Agency's comments ·on the Operation and Maintenance Manual dated February 1997. The Agency does not have any comments on the RA Report for Soils, therefore this report can be finalized.
Since the comments are not extensive, please incorporate these comments and submit a final O&M Manual no later than June 6, 1997. If you have any questions, please give me a call at 404/562-8824.

DRAFT O&M MANUAL COMMENTS
I. Section 5.2.3, Pages 5-3 and 5-4-The two valves noted in the comment below (Dwg 86619-
I-05) should be added to the valves to be opened listed in Step 2 of this procedure.
Valves V-38 and V-56 should be added to the valves to be closed listed in Step 3 of this
procedure. ;:.-,: : .
2. Page 7-3 indicates that MW-ID and MW-15D will be monitored if mounding of groundwater
occurs as a result of the operation of the infiltration gallery. If mounding occurs at MW-I ID,
monitoring well WP-ID should also be monitored for mounding and potential movement of
contaminants to the south. Therefore, benchmark elevations of groundwater in these areas
should be established and documented for potential future reference.
3. Monitoring wells MW-30D should be included for performance standard verification sampling
in Table 7-3. Monitoring well MW-2D should be monitored for performance standard
verification at least during 5 year review periods. Any monitoring wells previously
contaminated above groundwater standards for any contaminant of concern should also be
sampled and shown to be below performance standards prior to closure and system shut
down.
4. Heptachlor and heptachlor epoxide were erroneously excluded as contaminants of concern at
the site but should be included for evaluation during the 5 year review period since they are
mobile by-products of chlordane which was found in site soil but not in groundwater since it is
not very mobile. These chemicals are toxic at low concentrations and should be evaluated
before closure and system shutdown.
5. Appendix A -Drawings 86619-I-02, 03, 05 -The valve symbols on drawing 86619-I-02 show
. a ball valve with aline through the ball and a globe valve with the ball shaded. Drawings
86619-I-03 and 86619-I-05 show two types of valves, one with a ball without a line through it
(V-34) and one with shaded inlet and outlet ports (V-37). These two valves are used in the
same service, so it is assumed that these two symbols represent the same valve type that is
assUi-ned to be a ball valve. roese symbol discrepancies should be correcied on aii ihree
drawings.
6. Appendix A -Drawings 86619-I-05 ~ A valve is shown in the discharge or effluent piping
from each parallel carbon train. Both valves need valve numbers.

ATTACHMENT 1
LIMITED ACTION ALTERNATIVE MONITORING
Monitoring points will be in accordance with the sample locations shown on Figure I.
Sample frequencies are described in the RA WP and decision tree. The need to revise
monitoring locations will be assessed during remedy review meetings.
• Groundwater samples collected during the first year (i.e., first four quarterly sampling
efforts) will be analyzed for TCL pesticides using EPA method 8081 (or current
promulgated equivalent), including heptachlor and heptachlor epoxide per
NCDEHNR' s request. Results of these sampling efforts will be reviewed with the
Agencies at the end of the .first year and used to develop a parameter list for
subsequent sampling events. Potential parameters for subsequent analyses will be
screened by calculating the geometric mean concentration of individual TCL pesticides
at each monitoring well over the four quarterly sampling events. Constituents with
mean concentrations greater than the threshold values listed in Table I will be•
reviewed with the Agencies to determine if they should be included in subsequent
groundwater monitoring events. Information used to develop the groundwater
monitoring parameter list will include the location and frequency of detects,
concentration trends, and difference between mean concentration and threshold values.
Based on all information to date, the parameter list is anticipated to be .alpha-, beta-,
delta-and gamma-BBC.
• Surface water and stream sediment samples collected during the baseline event will be
analyzed for alpha-, beta-, delta-and gamma-BBC, heptachlor, and heptachlor epoxide
using EPA method 8081 (or current promulgated equivalent). Beptachlor and/or
heptachlor epoxide will be deleted from subsequent analyses if the mean groundwater
concentrations of these constituents from the baseline event are below their associated
MCL (0.4 ug/1 and 0.2 ug/1, respectively) (see Table !).
• Confirmation samples will be collected and analyzed in the event pesticide
concentrations in a stream surface water or sediment sample exceed risk-based levels
determined to be protective of potential human or ecologic receptors.
• Supplemental monitoring of Town Well No. 2 will be coordinated with the Town of
Aberdeen during each groundwater monitoring event. Samples will be analyzed for
drinking water series pesticides using EPA methods 505 and 508.
• In the event that a supplemental sample result is found to exceed 50% of a given
drinking water standard, Town Well No. 2 will be resampled on a rush basis. If the
sample confirms pesticide levels are greater than 50% of a given drinking water
standard, supplemental sampling will increase to a monthly basis to further assist
• •
monitoring of well-head pesticide concentration trends and prevent potential
exposures through the implementation of corrective measures, where appropriate.
When two successive months of supplemental sampling indicate that the
concentrations have again dropped to below 50% of the given drinking water
standards, supplemental sampling will be cori"ducted on the same frequency as
groundwater monitoring samples.
• Visual surveillance will be conducted during each routine monitoring event to
determine if new residential wells have been installed in the· downgradient area.
• Surface water and sediment samples will be collected from McFarland's Branch,
Aberdeen Creek and Ray's Mill Creek during the initial sampling event to document
baseline conditions. Sampling in Aberdeen Creek and Ray's Mill Creek will be conducted thereafter only if trigger levels in sentinel groundwater monitoring wells
MW-32L, MW-38L and MW-39L are exceeded. Trigger levels are provided in Table
2 of Attachment I. Sentinel wells MW-32L, MW~38L, and MW-39L will be screened
across the entire saturated thickness of the aquifer.

• The Site groundwater flow and transport models need to be refined.
• Groundwater concentration and mass reduction trends will be graphically evaluated
following the procedures described in Section H.4.1 _ of the RA WP.
Stream Surface Water/Sediment
• Surface water and sediments in Aberdeen Creek and Ray's Mill Creek will be
resampled if groundwater concentrations in the sentinel wells exceed trigger levels.
Monitoring data will be compared against risk-based levels determined to be
protective for long-term exposures. In the event transient increases in pesticide

POST ATTAINMENT REMEDY REVIEW
• Post-attainment monitoring data will be reviewed with the Agencies following
verification that groundwater performance standards have been achieved.
• Post-attainment monitoring will be conducted independently in the Upper and Lower
Black Creek aquifers for a minimum consecutive period of five years.
• Attainment of groundwater performance standards will be verified by conducting a
one-tailed t-test at the 95 percent confidence level between the average observed '
concentration at a given well and the groundwater performance standard.
• Monitoring of the Upper and/or Lower Black Creek aquifers may be independently
terminated.

RE: Comments on Operation and Maintenance (O&M) Manual
Geigy Chemical Corporation Site
NCD 981 927 502
Aberdeen, Moore County, NC
Dear Ms. Bennett:
The Operation and Maintenance ( O&M) Manual 'dated February 1997, for the Groundwater
Remedial Action Systems Operations for the Geigy Chemical Corporation Site, located in Aberdeen,
North Carolina has been received and reviewed by the North Carolina Superfund Section. The
following comments are offered by the North Carolina Superfund Section.
The O&M Manual appears to be fairly thorough and is therefore sufficient for the proposed work
with the following exceptions/considerations.
1. Page 7-3 indicates that MW-ID and MW-lSD will be monitored if mounding of
groundwater occurs as a result of the operation of the infiltration gallery. If
mounding occurs at MW-11D, monitoring well WP-ID should also be monitored for
mounding and potential ~ovement of contaminants to the south. Therefore,
benchmark elevations of groundwater in these areas should be established and
documented for potential future reference.
2. Monitoring wells MW-30D should be included for performance standard verification
sampling in Table 7-3. Monitoring well WP-2D should be monitored for performance
standard verification at least during 5 year review periods. Any monitoring wells
previously contaminated above groundwater standards for any contaminant of
. concern should also be sampled prior to closure and system shut down.
3. Heptachlor and heptachlor epoxide were erroneously excluded as contaminants of
concern at the site but should be included for evaluation during the 5 year review
period since they are mobile by-products of chlordane which was found in site soil
but not in groundwater since it is not very mobile. These chemicals are toxic at low
