OCP Case #2005-0834-FR
Dear Mr. Richmond,
Groundwater & Environmental Services, Inc. (GES), on behalf of Carroll Independent Fuel Company
(Carroll), respectfully submits this MW-18S Replacement Well Installation Report for the recent well
installation at 11791 Fingerboard Road, Monrovia, Maryland (Site). This summary report is being
provided per the Maryland Department of the Environment Oil Control Program (MDE-OCP) request
from the Monitoring Well Replacement Work Plan Approval letter dated December 12, 2014.
The monitoring well, named MW-18S-R, was installed on January 27, 2015. The well was installed with
the intention of it being a replacement for existing monitoring well, MW-18S, due to the anomalous water
quality, geochemical, and other analytical parameters observed at monitoring well MW-18S since it’s
installation in November 2010. The methodologies and results of the well installation, development, and
sampling activities are described below, along with recommendations for the future use of monitoring
wells MW-18S and MW-18S-R.
Well Installation
On January 23, 2015, a MISS Utility public utility markout request (ticket #15036014) was completed in
preparation for scheduled drilling activities. A second request (ticket #15038939) by GES was completed
on January 26, 2014 for the same location. On January 27, 2015, drilling activities initiated when Allied
Environmental Services (Allied), a Maryland-licensed driller, performed a “soft dig” for the first 5 feet
(ft) below grade surface (bgs) (i.e., utilizing air knifing techniques) as a precaution to avoid underground
utility disturbance. Encountered lithology within the first 5 ft of the subsurface included red-orange silt
and weathered rock, as anticipated by previous records of soil borings in the area. Cuttings throughout air
knifing and subsequent drilling activities were field screened for volatile organic compounds (VOCs)
with a calibrated photoionization detector (PID). Cuttings within the first 5 ft during utility clearance
digging elicited no elevated PID response.
A Drilltech D25 Air Rotary rig utilizing an 8-inch drill bit was positioned over the pre-cleared hole and
drilling was initiated. Cutting descriptions and screen values began at 5 ft bgs and were subsequently
collected at 5 ft intervals to 70 ft bgs. PID values ranged from 0.0 to 1.5 parts per million (ppm). Cuttings
were noted as red-orange and moist between 5 to 53 ft bgs and changed color to grey-green at 53 to 70 ft
bgs. The driller estimation of top-of-competent rock, based on soil cutting color change and penetration

resistance, was determined to be approximately 53 ft bgs. A boring log, which summarizes observed
lithology and PID screening levels, is attached as Appendix A.
MW-18S-R was cased through approximately 25 ft of weathered rock. The well was screened from 25 ft
bgs to 70 ft bgs. Little to no water was generated during drilling activities for the well. The annular
space between the casing and the surrounding weathered rock lithology had sand placed from 70 ft bgs up
to 22 ft bgs. Bentonite was placed from 22 ft bgs up to 9 ft bgs. Finally, a bentonite and cement grout
mixture was placed from 9 ft bgs up to approximately 1 ft bgs and allowed to harden. A well completion
report is included in Appendix B. The drilling cutting disposal manifest is attached as Appendix C.
On January 29, 2015, monitoring wells MW-18S-R and MW-18S were developed by Allied. Both wells
were developed by the surge and pump method. Approximately 40 gallons of groundwater was purged
from MW-18S-R, and 50 gallons was purged from MW-18S. The groundwater disposal manifest is
attached as Appendix D. Please note the disposal manifest includes an additional drum from the routine
quarterly groundwater sampling activities.
Groundwater Sampling
Groundwater samples were collected on February 12, 2015 from MW-18S-R and MW-18S and were
submitted for analysis of full suite VOCs with fuel oxygenates and naphthalene via EPA Method 8260,
total petroleum hydrocarbon – gasoline range organics (TPH-GRO) via EPA Method 8015B, total
chromium and total lead via EPA Method 200.8, dissolved chromium and dissolved lead via EPA Method
200.8, and hexavalent chromium via EPA Method 218.7.
The sample at MW-18S-R demonstrated MTBE a concentration of 470 micrograms per liter (µg/L). The
methyl-tert-butyl ether (MTBE) concentration at MW-18S was 27 μg/L. At MW-18S-R, the TPH-GRO
concentration was determined to be 400 µg/L, and at MW-18S the concentration was 63 µg/L. A
summary of the groundwater analytical results for VOCs and TPH is presented as Table 1.
The MW-18S-R sample had a total chromium concentration of 3.9 µg/L and a total lead concentration of
15 µg/L, and the concentration at MW-18S was 24 µg/L for total chromium and 2.9 µg/L for total lead.
The sample at MW-18S-R demonstrated a non-detect for dissolved chromium and dissolved lead, and the
sample at MW-18S demonstrated a concentration of 20 µg/L for dissolved chromium and 0.78 µg/L for
dissolved lead. At MW-18S-R, hexavalent chromium was determined at a concentration of 0.087 µg/L,
and at MW-18S the concentration for hexavalent chromium was determined to be 20 µg/L. The results of
MW18S-R and MW-18S do not correlate with each other. However, the results of MW-18S-R do
correlate with the surrounding wells, such as MW-7, MW-8, MW-13, MW-15D, and MW-18D. A
summary of the groundwater analytical results for metals parameters is presented as Table 2.
Groundwater analytical reports and associated Chains of Custody are attached as Appendix E.
Field Parameters
A YSI 600XL was used to collect down well water quality and geochemical readings at MW-18S-R and
MW-18S on February 12, 2015. The down well pH reading was 5.69 at MW-18S-R and 15.43 at MW18S. The reading for conductivity was 675 microsiemens per centimeter (µS/cm) at MW-18S-R and
5,633 µS/cm at MW-18S. The oxidation reduction potential (ORP) was 121.5 millivolts (mV) at MW18S-R and -57.6 mV at MW-18S. The field parameter values measured from MW-18S are anomalous
compared with other monitoring wells in the area such as MW-7, MW-8, MW-13, MW-15D, and MW-

18D, while the field parameter values from MW-18S-R align with the field parameters readings from the
surrounding wells. A summary of the field parameters is presented as Table 3.
Soil Sampling
Two soil samples were collected on February 12, 2015 from MW-18S-R at 65 ft bgs and 70 ft bgs. MW18S-R(65’) and MW-18S-R(70’) were submitted for analysis of VOCs via EPA Method 8260, total lead,
total iron, and total chromium via EPA 6010, hexavalent chromium via EPA Method 7190A, pH via EPA
Method 9045, and ORP via ASTM D1498.
The soil sample collected at 65 ft bgs for MW-18S-R(65’) demonstrated a concentration of MTBE of 11
micrograms per kilogram (µg/kg) and a concentration of tert-butyl alcohol (TBA) of 66 µg/kg. MW-18SR(65’) had detections of total chromium of 14.7 mg/kg, of total iron of 27,300 mg/kg, and of total lead of
18.0 mg/kg and hexavalent chromium was non-detect. The lab derived ORP at MW-18S-R (65’) was 363
mV and the pH was 6.18. The soil sample collected at 70 ft bgs, MW-18S-R(70’), had detections of
MTBE of 10 µg/kg and a concentration of TBA of 70 µg/kg. MW-18S-R(70’) had a total chromium
concentration of 15.2 mg/kg, a total iron concentration of 32,500 mg/kg, a total lead concentration of 4.10
mg/kg and hexavalent chromium was non-detect. The lab derived ORP at MW-18S-R(70’) was 376 mV,
and the pH was 6.62. Summaries of the soil analytical results are presented as Table 4 and Table 5.
The soil analytical report and associated Chain of Custody is attached as Appendix F.
Conclusions
As described in the Monitoring Well MW-18S Replacement Work Plan, MW-18S-R was installed in
order to replace MW-18S, which has shown atypical results for a number of monitoring parameters.
Based on the water quality, geochemical, and analytical parameters that were collected, MW-18S-R has a
strong correlation with the surrounding wells, whereas MW-18S has particularly high pH, high
conductivity, low ORP, and high levels of metals. This suggests that MW-18S is an anomalous well that
has a poor hydraulic connection to the aquifer. In addition, it suggests that the levels of hexavalent
chromium observed at MW-18S don’t exist outside of the immediate vicinity of MW-18S. MW-18S is
not a representative well.
As agreed to between Carroll and the MDE during the Oct 2014 meeting to discuss Carroll’s dispute of
the MDE’s request to continue sampling all monitoring for metals, Carroll will collect one additional
round of metals samples from select monitoring and potable wells (including MW-18S and MW-18S-R)
during the 2Q 2015 sampling event. If the water quality, geochemical, and analytical parameters continue
to suggest MW-18S is not representative of the aquifer conditions, GES recommends abandoning MW18S and conducting future sampling in this area of the site at monitoring well MW-18S-R instead.
Routine sampling at MW-18S-R (and all other monitoring wells) beyond the 2Q 2015 will include VOCs
and TPH-GRO.
We appreciate the continued guidance of the MDE-OCP on this project. If you have any questions or
would like additional information, please contact the undersigned at 800-220-3606, extension 3726 or
3717, respectively, or Herb Meade at 410-261-5450.
Sincerely,

parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg) or one gram per million grams. For
aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight
very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas.

Dry weight
basis
Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
concentration to approximate the value present in a similar sample without moisture. All other results are reported on an
as-received basis.
Laboratory Data Qualifiers:
B - Analyte detected in the blank
C - Result confirmed by reanalysis
E - Concentration exceeds the calibration range
J (or G, I, X) - estimated value ≥ the Method Detection Limit (MDL or DL) and the < Limit of Quantitation (LOQ or RL)
P - Concentration difference between the primary and confirmation column >40%. The lower result is reported.
U - Analyte was not detected at the value indicated
V - Concentration difference between the primary and confirmation column >100%. The reporting limit is raised due to this disparity
and evident interference…
Additional Organic and Inorganic CLP qualifiers may be used with Form 1 reports as defined by the CLP methods.
Qualifiers specific to Dioxin/Furans and PCB Congeners are detailed on the individual Analysis Report.
Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, ISO17025) unless
otherwise noted under the individual analysis.
Measurement uncertainty values, as applicable, are available upon request.
Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the
collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be
meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held
responsible for sample integrity, however, unless sampling has been performed by a member of our staff.
This report shall not be reproduced except in full, without the written approval of the laboratory.
Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as “analyze immediately” are not performed within
15 minutes.

ppm
parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg) or one gram per million grams. For
aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight
very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas.
ppb
parts per billion
Dry weight
basis
Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
concentration to approximate the value present in a similar sample without moisture. All other results are reported on an
as-received basis.
Laboratory Data Qualifiers:
B - Analyte detected in the blank
C - Result confirmed by reanalysis
E - Concentration exceeds the calibration range
J (or G, I, X) - estimated value ≥ the Method Detection Limit (MDL or DL) and the < Limit of Quantitation (LOQ or RL)
P - Concentration difference between the primary and confirmation column >40%. The lower result is reported.
U - Analyte was not detected at the value indicated
V - Concentration difference between the primary and confirmation column >100%. The reporting limit is raised due to this disparity
and evident interference…
Additional Organic and Inorganic CLP qualifiers may be used with Form 1 reports as defined by the CLP methods.
Qualifiers specific to Dioxin/Furans and PCB Congeners are detailed on the individual Analysis Report.
Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, ISO17025) unless
otherwise noted under the individual analysis.
Measurement uncertainty values, as applicable, are available upon request.
Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the
collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be
meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held
responsible for sample integrity, however, unless sampling has been performed by a member of our staff.
This report shall not be reproduced except in full, without the written approval of the laboratory.
Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as “analyze immediately” are not performed within
15 minutes.
