1 INTRODUCTION AND BACKGROUND
RPS Group, Inc. (RPS), on behalf of Chromalox, Inc. (Chromalox), has prepared this report presenting the
results of the Second 2024 Bi-Annual groundwater monitoring event conducted at Chromalox’s property located
at 2150 North Rulon White Boulevard in Ogden, Utah (the site). A site location map is included as Figure 1. On
August 29, 2011, Chromalox entered into an agreement with the Utah Department of Environmental Quality
(UDEQ) to address the identified contamination under the Voluntary Clean-up Program (VCP) of the UDEQ.
VCP number 073 was assigned to the site. As part of an approved Interim Remedial Action Plan (IRAP),
Chromalox is submitting this 2024 Second Bi-annual 2024 Groundwater Monitoring Report that documents
groundwater conditions at the site. Analytical results of this report are compared to baseline groundwater
conditions established in the 3rd Quarter 2019 groundwater monitoring event. Historical site investigations and
groundwater monitoring results have been provided in previous bi-annual reports submitted to UDEQ.

2 SITE BACKGROUND
2.1 Site Description
The site is comprised of 14.04 acres located at the northeast corner of the intersection of North Rulon White
Boulevard and W 2150 N. The site location and site layout are depicted in Figures 1 and 2, respectively.
Chromalox manufactures various industrial heating elements at the site, including tubular heating elements,
component heaters (strip and ring, cartridge, and sheet metal), immersion elements (large and small flanged,
screw plugs, and over-the-side), and system heaters (heat transfer and circulation).
2.2 Environmental Setting
A summary of the site environmental setting is provided below.
2.2.1 Hydrogeology and Groundwater Flow Elevation
Groundwater at the site has generally been encountered between approximately 7 and 28 feet below ground
surface (bgs). Permanent groundwater monitoring wells are installed at two depth ranges; shallow wells are
installed at depths between approximately 20 to 30 feet bgs and deep wells are installed at depths of
approximately 35 to 43 feet. However, it should be noted that the apparently variable depth to groundwater at
the site does not appear to reflect topography, as the elevation change noted across the entire site is only 10
feet. Rather, the previously observed variable depth to groundwater is likely the result of two factors: 1) the low
hydraulic conductivity of the native clayey soil that limits horizontal and vertical movement, and 2) the presence
of groundwater within discontinuous sand lenses in the native clayey soil. Review of logs of area potable water
supply wells surrounding the Chromalox facility indicates that these wells are completed at deep levels (i.e.,
greater than 100 feet bgs). Review of area well logs suggests that the geology in the area is mostly clay with
discontinuous sand and silt lenses over 150 feet thick.

3 GROUNDWATER MONITORING PROGRAM
RPS conducted the Second Bi-Annual 2024 groundwater monitoring event on September 10 and 11, 2024, in
accordance with the State-approved groundwater monitoring plan dated June 2019. A total of 24 site wells were
gauged for depth to water and depth to bottom 1,2. A total of 16 wells were sampled for Volatile Organic
Compounds (VOCs), 1,4-dioxane, and dissolved Resource Conservation and Recovery Act (RCRA) metals.
SVOCs and TPH are no longer required for sampling analysis and have been removed from the sampling plan
per UDEQ email sent on March 6, 2024. Please refer to the table below for analytes, methods, and media used
while sampling wells. Table 1 includes a list of all wells that were gauged/sampled.
Field activities consisting of groundwater sampling were performed by Tetra Tech of Salt Lake City, Utah. A site-
specific Health and Safety Plan developed for the site was followed by RPS and Tetra Tech personnel during
field activities.
The following tasks were completed to implement the scope of work for this groundwater monitoring event:
• Inspected each well head and noted the condition of well vault, bolts, lids, well caps and gaskets;
• Measured the static groundwater levels (water levels) in 24 site wells. The tape and probe were
decontaminated between each well to minimize the potential for cross-contamination;
• Purged and sampled the groundwater from 16 of the 24 monitoring wells using low flow sampling
techniques;
• Recorded water quality parameters such as pH, electrical conductivity (EC), temperature, dissolved oxygen
(DO), oxygen reduction potential (ORP), and turbidity using a flow-through cell at regular intervals as part of
the purging and sampling activities.
Details on these activities is presented in the next sections.

4 GROUNDWATER SAMPLING
The field activities of this sampling event are presented in this section.
4.1 Well Head Inspection and Maintenance
Well heads were inspected prior to gauging depth to groundwater at each well. Damaged bolts, lids, well caps,
and gaskets were noted and will be repaired or replaced as needed during the subsequent groundwater
sampling event. Any significant water accumulation in the well vault is evacuated prior to opening the well cap
and sampling.
4.2 Well Head Inspection Availability
In March of 2023 in accordance with the State-approved groundwater monitoring plan dated June 2019, 38 site
wells were gauged for depth to water and depth to bottom and 29 wells were sampled for Volatile Organic
Compounds (VOCs), 1,4-dioxane, Semi-VOCs (SVOCs), and Dissolved Resource Conservation and Recovery
Act (RCRA metals, including Iron and Manganese. In June of 2023 eleven monitoring wells (GMW-1, GMW-2,
GMW-3, GMW4, GMW-7, MW-5, MW-11, MW-15, MW-21, MW-22, and GP-13) were properly plugged and
abandoned in June 2023 ahead of site improvement construction. As appropriate and in consultation with
UDEQ, the monitoring wells will be replaced following the site improvements. During the sampling event in
September 2024 monitoring well INJ-2 was scheduled to be gaged; however, the well bore was inaccessible
during the field effort because a bolt locking the protective cover had been sheard. Additionally, MW-9 and MW-
12S was unable to be located and is marked as missing. Ultimately GMW-6 was removed from the groundwater
monitoring schedule as this area is sufficiently being evaluated by (and may be duplicative of) nearby wells but
was gauged only during the September 2024 groundwater sampling event. This in turn left only 24 site wells to
be gauged for depth to water/depth to bottom and 16 wells to be sampled for Volatile Organic Compounds
(VOCs), 1,4-dioxane, and dissolved Resource Conservation and Recovery Act (RCRA) metals during the
September 2024 groundwater sampling event.
4.3 Groundwater Elevations
The wells were gauged for depth to groundwater using a calibrated Solinst electrical water interface probe.
Depths were measured to the nearest 0.01 feet and referenced to the top of each surveyed well casing. The
tape and probe were decontaminated after each measurement to minimize the potential for cross contamination.
Groundwater elevations from shallow and deep monitoring wells were utilized to create shallow and deep
groundwater potentiometric surface maps shown on Figure 3a and 3b. Previously installed deep monitoring
wells (MW-1, MW-5, MW-7, MW-8, MW-9 and GMW-5) are located near the northeast portion of the site. Deep
monitoring wells installed in 2019 (MW-12D, MW-13D and MW-14D) are nested with shallower wells in the
vicinity of AOC 4 and AOC 6. The remaining monitoring wells are shallow and distributed across the site. Figure
2 presents the locations of the monitoring wells at the site. Groundwater flow direction in both the shallow and
the deeper groundwater bearing units are somewhat variant over time but continues to indicate an overall north
to northwest flow direction. Groundwater flow direction at the site will continue to be assessed during well
gauging in any subsequent bi-annual groundwater sampling events. Groundwater elevations are summarized on
Table 1.

4.4 Groundwater Purging
During purging, water quality parameters (temperature, pH, EC, turbidity, DO, and ORP) were measured and
recorded at regular intervals using a calibrated flow-through cell. Prior to initiating groundwater sampling, each
well was purged to remove the stagnant water in the tubing. This volume was calculated by adding the depth of
the pump multiplied by the tubing diameter (volume of discharge line) to the standard volume of the peristaltic
pump (estimated at 395 milliliters). Thereafter, groundwater was purged until the water quality indicator
parameters had stabilized to within five percent (%) difference between consecutive readings.
Groundwater purge and sampling field forms are included as part of Appendix B of this report.
4.5 Groundwater Sampling
After purging the wells, groundwater samples were collected from each well through dedicated tubing. Care was
taken to collect the groundwater samples at a low flow rate of approximately 250 mL/min to avoid agitating the
preservative present in the sampling bottles and to help fill the bottles without headspace, thereby minimizing off
gassing of VOCs from the samples. Samples for VOC and 1,4-dioxane analyses were collected first.
Groundwater samples were collected into laboratory-provided sample containers for each respective analysis. A
summary of the sampling and analysis analytical results are presented in Table 2.
Each sample container was labeled with the date and time of sample collection, the analyses requested, and a
unique sample name. Following labeling, the samples were kept on ice in a cooler. A total of 16 primary samples
(including two duplicate samples, discussed below) were sent under chain-of-custody to Chemtech-Ford
Laboratories in Sandy, Utah, a state-certified environmental laboratory, for analysis.
4.6 Quality Assurance and Quality Control (QA/QC)
4.6.1 Field QA/QC
Duplicate samples were collected at wells MW-20 and GMW-5 and analyzed for VOCs, 1,4-dioxane, and
dissolved RCRA metals. The duplicate samples for all methods excluding metals are generally consistent with
the parent sample. Please refer to the Data Usability Study in Appendix C for further detail regarding duplicate
samples.
4.6.2 Data Useability Study
The laboratory performed internal QA/QC tests to ensure analytical precision, accuracy, representativeness,
comparability, completeness, and sensitivity. These tests included method blanks, surrogates, laboratory control
spike and laboratory control spike duplicates, matrix spike and matrix spike duplicates, laboratory duplicates,
and initial and continuing calibration checks. A Data Usability Study shown in Appendix C outlines the laboratory
QA/QC process and was conducted for conformance to the requirements of the Quality Assurance Project Plan
(QAPP) adopted for site sampling in June 2012.

4.6.3 Decontamination Procedures
All commonly used equipment that encountered potentially contaminated groundwater was decontaminated
between sampling locations using the three-stage wash and rinse decontamination procedure (i.e., rinse
equipment with tap water, wash equipment with a non-phosphate detergent, and final rinse with distilled water).
4.7 Investigation Derived Wastes
The waste generated from the groundwater sampling field activities (decontamination water and purged
groundwater) is stored on site in an appropriately labeled, sealed, and in a covered Department of
Transportation (DOT) approved 55-gallon drum. The waste will be managed offsite at a further date.

5 GROUNDWATER ANALYTICAL RESULTS
Groundwater samples were analyzed by Chemtech-Ford, a NELAC accredited lab by the National
Environmental Laboratory Accreditation Program (NELAP) (Utah, UT000272024-40) for the parameters
discussed in Section 3. The samples were relinquished to the laboratory with the appropriately signed chain-of-
custody forms completed at the time of sampling. Groundwater analytical testing results are summarized in
Table 2. Trend graphs for each monitoring well are presented in Appendix A. Figure 4A and 4B show the shallow
vs deep groundwater monitoring wells that includes analytical callouts. The laboratory analytical reports and the
corresponding COCs are presented in Appendix D.
5.1 VOCs
A summary of detected VOCs is presented in Table 2. Nine VOCs were detected at a concentration that
exceeded the UDEQ groundwater standard, USEPA Maximum Contaminant Level (MCL), and/or the USEPA
risk-based derived Tapwater Regional Screening Level (RSL). Concentrations of analytes in exceedance of the
aforementioned standards in the monitoring wells are discussed below:
• 1,1-DCE was reported in approximately seven monitoring wells above one or more applicable standards.
Concentrations ranged from 0.013 mg/L in monitoring well MW-14D to 57.9 mg/l in MW-14S.
• 1,1-DCA was reported in approximately five monitoring wells above one or more applicable standards.
Concentrations ranged from 0.0034 mg/L in monitoring well MW-20 duplicate sample to 3.57 mg/l in MW-
14S.
• 1,2-DCA was reported in approximately four monitoring wells above one or more applicable standards.
Concentrations ranged from 0.0008 mg/L in monitoring well MW-16 to 0.155 mg/l in MW-14S.
• 1,1,2-TCA was reported in approximately two monitoring wells above one or more applicable standards.
Concentrations ranged from 0.0023 mg/L in well MW-13S to 0.099 mg/L in well MW-14S.
• PCE was reported in approximately one monitoring well (MW-14S) at a concentration of 0.0174 mg/l, which
exceeds one or more of the applicable standards.
• TCE was reported in approximately two monitoring wells above one or more applicable standards.
Concentrations ranged from 0.0055 mg/L in well MW-13S to 0.177 mg/L in well MW-14S.
• Chloroform was reported in approximately two monitoring wells above one or more applicable standards.
Concentrations ranged from 0.0035 in well MW-13s to 0.0047 in well MW-14s.
• Naphthalene was reported in approximately one monitoring well (MW-20) at a concentration of 0.0008 mg/l,
which exceeds the RSL value.
• Vinyl Chloride (VC) was reported in seven monitoring wells above one or more applicable standards.
Concentrations ranged from 0.0008 mg/l in monitoring well MW-13D and MW-20 to 0.0093 mg/l in MW-13S.
The chlorinated VOCs in groundwater continue to remain mostly situated at the northern and eastern portions of
the site, however as shown on the analytical trend graphs in Appendix A significant reductions of chlorinated
solvents in monitoring wells MW-12D, MW-13D, and, MW-7, continue to be seen. Although GMW-1 was plugged
in June 2023, it is assumed based on historical data that this area of the site remains unimpacted. The highest
concentrations of analytes above the UDEQ Groundwater Quality Standards and USEPA RSLs and MCLs
SECOND BI-ANNUAL 2024
GROUNDWATER MONITORING REPORT
CHROMALOX
10
remain detected in the vicinity of the injection wells located near AOC 4 & AOC 6, at the northwestern portion of
the site.
5.1.1 1,4-dioxane
1,4-dioxane was reported above the applicable standards in 9 of the monitoring wells ranging from 0.0011 mg/l
in well MW-17 up to 0.462 mg/l in well MW-13S. Neither a UDEQ Groundwater Quality Standard nor an MCL
has been established for 1,4-dioxane. Analytical trend graphs for VOCs are included in Appendix A.
5.2 Dissolved Metals
During the Second Bi-Annual 2024 sampling event on September 10 and 11, 2024, RPS analyzed samples for
dissolved RCRA Metals, including dissolved iron and dissolved manganese.
5.2.1 Dissolved Metals
Two dissolved metals were reported at a concentration above the established standards. Concentrations of
analytes in exceedance of the aforementioned standards in the monitoring wells are discussed below:
•Arsenic (dissolved) was reported in approximately 9 monitoring wells above one or more established
standard. Concentrations ranged from 0.05 mg/l in monitoring well MW-14S to 0.34 mg/l in well MW-7.
•Manganese (dissolved) was reported in three monitoring wells above the RSL. Concentrations ranged from
0.454 mg/l in monitoring well GMW-5 duplicate sample to 6.24 mg/l in well MW-14S.
Concentrations of dissolved arsenic above groundwater screening criteria continue to be distributed throughout
the site. No monitoring well concentrations of Barium are above groundwater screening criteria. Manganese
detections in excess of the RSL was limited to three wells in the vicinity of AOC-2, AOC-6, and the eastern end
of the site during this monitoring period. The dissolved metals that appear in the groundwater correlate with
naturally occurring metals found in soils at and around the site, these metals are assumed to be naturally
occurring. Most metal concentrations near the treatment areas appear to be generally stable and continue to
show no significant long-term increases following remediation activities. Metal concentrations within the
treatment areas will continue to be monitored to verify any long-term influence of the injection treatments on the
release of metals to groundwater. Analytical trend graphs for dissolved metals are included in Appendix A
5.3 SVOCs
SVOCs are no longer required and have been removed from the sampling plan per UDEQ email sent on March
6, 2024, stating “We took a look at your request to remove SVOCs/PAHs from the bi-annual analyte groundwater
monitoring list. We agree that SVOCs and PAHs do not appear to be a COC for the VCP site. Please go ahead
and remove these analytes from the sampling list moving forward.”

6 SUMMARY AND FUTURE ACTIVITIES
On September 10 and 11, 2024, RPS conducted the Second Bi-Annual 2024 groundwater monitoring event that
included gauging of 24 monitoring wells and sampling of 16 of the 24 monitoring wells at the site.
6.1 Summary
Based on the analytical results from all the sampling events, concentrations of the chlorinated VOCs appear to
continue to fluctuate somewhat over time, but generally maintain concentrations in the same order of magnitude
in each of the monitoring wells. The highest concentrations detected were still reported in the vicinity of AOC 4
and AOC 6. The following conclusion and recommendations are based on the results of the current and overall
groundwater monitoring program:
• Groundwater flow direction is somewhat variant over time but continues to indicate an overall north to
northwest flow direction.
• Due to past injection activities, the groundwater conditions in the injection wells are not considered to be
representative of average groundwater conditions at the site. As such, on March 2, 2023, UDEQ approved
of the removal of injection wells INJ-2 through INJ-9 from the groundwater monitoring schedule in favor or
relying on data collected from nearby wells. Additionally, monitoring well GMW-6 was removed from the
groundwater monitoring schedule as this area is sufficiently being evaluated by (and may be duplicative of)
nearby wells.
• Analytical parameter concentrations for the monitoring wells were generally consistent with the previous
quarter’s sampling event with a mixture of increases and decreases in concentrations of regulated
constituents. 1,4-Dioxane concentrations are more widely distributed, but the highest levels are still located
in these AOCs.
• Elevated VOCs are also still being detected along the eastern property boundary in monitoring wells (MW-
16, and MW-20) and appears to be related to an unknown source area.
6.2 Future Activities
The next sampling event (March 2025) will be performed in accordance with UDEQ agreements and the State-
approved June 2019 groundwater monitoring plan. As UDEQ is aware, Chromalox is currently making site
improvements. Development activities include the construction of a 100,000 square foot building to the east of
the existing facility, affecting several existing monitoring wells. As such, and at the request of UDEQ, RPS has
overseen the proper decommissioning of nine monitoring wells in order to eliminate the potential conduit for
pollution to reach the groundwater. New monitoring wells, where warranted, will be installed following the
completion of site development activities.

Data Usability Study

Data Quality Usability Summary
Groundwater Sampling Event September 2024
Chromalox, Inc., Ogden, Utah
VCP 073

One data package from CHEMTECH-FORD was reviewed for the analysis of groundwater samples
collected between September 10, 2024, and September 11, 2024, at the Chromalox facility in Ogden,
Utah. Data was reviewed for conformance to the requirements of the Quality Assurance Project Plan
(QAPP) adopted for site sampling in June 2012. Please refer to Appendix E for the March 2024 analytical
reports.
The data package reviewed was conducted by CHEMTECH-FORD, Sandy, Utah. CHEMTECH-FORD is
NELAC accredited by National Environmental Laboratory Accreditation Program (NELAP) (Utah,
UT000272024-40).
Intended Use of Data: To provide current data on concentrations of chemicals of concern (COCs) in
groundwater at the affected property.

Project Objectives: The project objectives were to obtain laboratory analysis of COCs in groundwater at
quantitation limits below the applicable Utah Department of Environmental Quality (UDEQ) voluntary
cleanup program, EPA’s Regional Screening Levels or MCLs and in accordance with quality
assurance/quality control requirements of UDEQ.

Samples Evaluated: A total of approximately 19 samples were reviewed as part of this DUS. The samples
have been collected over the course of the 2nd round 2024 Bi-Annual GW Monitoring Investigation
(September 2024) and include approximately:
• 16 groundwater samples from monitoring wells
• 2 duplicates from groundwater samples
• 1 Trip blank

Table D-1 lists the client sample identifications for each laboratory report (field identifications) cross-
referenced to laboratory sample identifications, date sampled, and media sampled.

Chain-of-Custody, Sample Preservation and Holding Times: Samples were evaluated for agreement
with the Chain-of-Custody (COC). The field identifications on the COC were cross-referenced to laboratory
identifications and corresponding QC data. All samples were received in the appropriate containers and in
good condition and met the laboratory’s acceptance criteria for temperature. The samples were received in
good condition and properly preserved on ice.
The contract laboratory correctly conducted analyses for chemicals on the COC. Samples were extracted
and analysed within specified holding times.

Analytical Results: Analytical results for the listed samples are reported on microgram per liter and
milligram per liter basis. Non-detected results are reported as the value of the sample quantitation limit
(SQL). Qualified data are reported in Table D-2 and D-3. All anomalies were discussed in the case narrative
and QC data summaries associated with each data package.

Accuracy - Accuracy is the degree of mutual agreement between an individual measurement and a
reference accepted as a true value. Accuracy can be assessed using MS/MSD, lab control
samples (LCS), calibration standard, laboratory, field blanks and spiked environmental
samples. When reviewing the analytical data packages the following observations are made:

• Calibrations: A few of the LCS were flagged with E, the analyte concentration exceeds the upper
limit of the calibration range of the instrument established by the initial calibration (ICAL). None of
the project samples were qualified regarding calibrations.

• Surrogate Recovery Data: As mentioned above, a minor number of analytes in the associated
data package LCSs recovered outside of laboratory recovery standards.

• Internal Standards: Internal standards were not reported in any of the data packages, and it
appears they were within acceptable limits.

• Matrix Spike (MS)/Matrix Spike Duplicate (MSD): As mentioned above, a minor number of
analytes in the associated data package LCSs were outside of MS/MSD laboratory control limits
for percent recovery.

• Method Quantitation Limits: Method quantitation limit data met acceptance limits.

• Interference Check Standard: Interference check standard recoveries were determined
acceptable by the laboratory.

• Field Procedures: Groundwater samples were collected in accordance with RPS SOPs and
approved scopes of work.

Data was reviewed and validated as described in the QAPP and the results of the review/validation are
discussed in this DUS. The following laboratory submittals were examined:

• Sample Summary: A review of the sample summary portion of each report revealed that each
sample was properly logged in and the requested methods and analyte groupings were noted.

• Case Narrative: The case narrative of each of the sample reporting packages note that the
samples were properly received within temperature and holding times. No exceptions to quality
control were noted and no exception reports were provided.

The above review was followed by an evaluation of whether or not the Data Quality Objectives (DQOs)
were met. The DQOs are as follows:

Precision - Precision is a measure of the reproducibility (mutual agreement) of individual measurement
under a similar set of conditions. The overall data precision of a sampling event has a sampling and an
analytical component and will be assessed by replicate measurements of field and laboratory duplicate
samples. The routine comparison of precision is measured by the relative percent difference (RPD)
between duplicate sample measurements. Field duplicates access the precision for the field sample
collection and management system. Laboratory duplicates or matrix spike/matrix spike duplicate (MS/MSD)
samples are used to evaluate laboratory precision.

• Field Duplicate Data: Field duplicate precision comparisons and calculations were performed for
four groundwater samples and the associated duplicates. Duplicates are blind to the laboratory.
• FDUP-001 (9/10/2024) is a duplicate sample to MW-20; and
• FDUP-002 (9/11/2024) is a duplicate sample to GMW-5.

All duplicate sets, most analytes where below the detection limits and the results or SQLs were mostly
identical with their matching sample, excluding metals. Analytes detected were deemed acceptable and
passed the RPD% criteria (Table D-2).

One analyte in groundwater duplicate set (MW-20) FDup-001 did not meet the threshold of being
acceptable because the calculated RPD% was greater than 50%. The failures mostly come from volatile
organic compounds (VOCs). These failures appear to be the result of:
• The inherent uncertainty of creating field duplicate groundwater samples.
• A detected value but below the reporting limit, therefore, result is an estimated concentration.
• An estimated low due to low recovery of CCV.
• An estimated low due to low recovery of LCS.

The laboratory did not mention precision issues in the laboratory package narratives and the field duplicate
samples had showed accurate reproducibility. Therefore, it is judged that precision is within acceptable
limits for the sampling event.

Representativeness - Representativeness expresses the degree to which sample data accurately and
precisely describe the characteristics of a population of samples, parameter variations at a sampling point,
on environmental conditions they intend to represent. Representativeness is a qualitative parameter that
is primarily concerned with the proper design of the sampling program and will be ensured using established
field and laboratory procedures and their consistent application.
• There were no unexpected COCs detected. Conversely, except for accounting for known
contaminant degradation and natural attenuation, there were no COCs that are typically in
the groundwater at the site and were absent.

Comparability – Comparability is a qualitative parameter expressing the confidence that one data set is
comparable with another. Sample data will be comparable for similar samples collected under like
conditions. This goal is achieved using standard techniques to collect and analyze representative samples
and reporting analytical results with appropriate units.
• The data is considered comparable to past sample results in the same monitoring wells and
collected under the same conditions. There were no unexpected COCs detected.
Conversely, except for accounting for known contaminant degradation and natural
attenuation, there were no COCs that are typically in the groundwater at the site and were
absent.

Completeness - Completeness is a measure of the amount of valid data obtained from a measurement
system compared with the amount that was expected to be obtained under normal conditions. To be
considered complete, the data set must contain all analytical results and data specified for the project.
• The sampling effort is considered 100% complete and all samples expected and validated
were delivered.

Sensitivity - Sensitivity is expressed in the form of the method detection limit (MDL) or quantitation limit for
the analytical method selected. Quantitation limits, however, reflect the influences of the sample matrix on
method sensitivity and are typically higher than detection limits. Quantitation limits indicate the amount of
material needed to produce an instrument response that can be routinely identified and reliably quantified.
For the purposes of site characterization, concentrations may be detected at or below laboratory
quantitation limits for some methods; therefore, laboratory will provide results to the sensitivity of the MDL
with appropriate data qualifiers. The reporting limits (RL) are the level to which data are reported
administratively for a specific test method and/or sample. The laboratory maintains RLs higher than MDLs.
The RL is considered the same as sample quantitation limit (SQL). ECS Lab Sciences QAM summarizes
DLs and RLs for various parameters. All RL or MDLs must at a minimum meet the RSL or MCL screening
levels for the evaluation.
• The reported analytical data in the laboratory data package is considered sensitive in that
both the MDLs and RLs is lower than the corresponding RSL or MCL.

Summary: The results of supporting quality control analyses (QC) were summarized on the Laboratory
Review Checklists (LRCs), Exception Reports (ERs), and in the case narratives, all of which were included
in this review. The groundwater data was determined usable for the purpose of determining COC
concentrations at the affected property.
Except as previously noted, the LRCs, associated ERs, and reportable data included in this review are
included with each laboratory report of the Chromalox 2024 Bi-Annual Groundwater Monitoring Reports.

Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
Flag Descriptions
E = The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate (CLP
E-flag).
J = Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J-Flag).
J-High = Estimated High due to high recovery of LCS or CCV
J-High-C = Analyte estimated high based on CCV recovery
J-LOW-C = Estimated low due to low recovery of CCV
J-LOW-L = Estimated low due to low recovery of LCS
