1.0 INTRODUCTION
1.1 Site Information
On behalf of Rockingham County, LaBella Associates, PC (LaBella) has prepared this Water Quality Monitoring Report for the Rockingham County Solid Waste Management Facility. The Facility is owned
by Rockingham County (the County) and operated by Wall Recycling, LLC (Wall) and is operating under
North Carolina Solid Waste Permit Nos. 79-01 and 79-04. The Facility is located off Shuff Road, west
of the town of Wentworth in central Rockingham County, North Carolina. The property boundary is
shown on a portion of the 7.5-minute USGS topographic map for Bethany and Southwest Eden, North
Carolina (Figure 1). The property is surrounded by rural wooded areas and farmland.
The Rockingham County Solid Waste Management Facility (the Facility) consists of two landfills, a
closed, unlined Municipal Solid Waste (MSW) landfill and an active Subtitle D MSW landfill. The closed
MSW landfill operated under Permit 79-01 and is comprised of five areas, referred to as Areas I, II, III,
IV (collectively referred to as Areas I-IV), and Area V. Areas I-IV all closed before October 9, 1993. Area
V closed after October 9, 1993. The active Subtitle D MSW landfill is comprised of four contiguous
cells, designated Phases 1, 2, 3, and 4, and is operated under Permit 79-04.
1.2 Site Geology
The Facility is located in the Piedmont physiographic province within the Milton Belt, which contains
schist and gneiss of amphibolite facies, with minor areas of granitic intrusive rock (Carpenter, 1982).
Carpenter mapped bedrock in the vicinity of the site as biotite gneiss and schist, locally interlayered
with hornblende gneiss and schist and felsic gneiss. Map patterns and outcrop information for the Milton Belt indicate that the metamorphic rock is broadly folded, with foliation of moderate to gentle
dips. Strikes for outcrops are variable, owing to the generally flat-lying nature of the geologic structure;
the regional strike is to the east-northeast (Carpenter, 1982).
Triassic diabase dikes shown in the region mapped are based on aeromagnetic surveys. Occasional
outcrops have consistent strikes of approximately 10 to 20 degrees west of north. Quaternary alluvium
is mapped in the larger drainages in the site vicinity, including Jacob’s Creek and its tributaries.
1.3 Regulatory Status
Areas I-IV (Permit 79-01) were closed before the implementation of RCRA Subtitle D requirements.
The landfill is currently monitoring groundwater following criteria outlined in Rule .0500 of the North
Carolina Solid Waste Management Regulations (NCSWMR - 15A NCAC 13B) for municipal solid waste
landfills (MSWLF) closed before October 9, 1993. Area V groundwater monitoring is completed in
accordance with NCSWMR § .1633 (Detection Monitoring Program).
The Subtitle D Landfill (Permit 79-04) groundwater monitoring program entered Assessment
Monitoring per 15A NCAC 13B .1634 in 2017; however, in a letter dated March 22, 2018, the North
Carolina Department of Environmental Quality – Solid Waste Section (NCDEQ-SWS) authorized
Rockingham County to return all the Subtitle D Area monitoring wells, except for monitoring wells
7904-MW19 and 7904-MW19R, to Detection Monitoring. Monitoring well 7904-MW19 became a performance well and monitoring well 7904-MW19R stayed in Assessment Monitoring. Surface water
monitoring is performed following NCSWMR § .0602.

2.0 FACILITY MONITORING PROGRAMS
The monitoring program at the Facility is completed as required by the NCSWMR. The current
groundwater monitoring programs for each of the landfills, surface water, and the leachate storage system are included in LaBella’s April 2021 Water Quality Monitoring Plan (WQMP). The September
2023 Monitoring Event was conducted in accordance with the April 2021 WQMP, and the monitoring
program is presented below.
2.1 Closed Landfill Areas I-IV Monitoring Program
There are nine groundwater monitoring wells associated with Areas I-IV. Monitoring well 7901-MW4A
is the upgradient background well. Monitoring wells 7901-MW6, 7901-MW7, 7901-MW12S,
7901-MW12D, 7901-MW13S, and 7901-MW13D are monitored as compliance wells. Monitoring
wells 7901-MW3A and 7901-MW8 are used to obtain groundwater levels. All wells are sampled
semiannually, except 7901-MW12S and 7901-MW12D, which are sampled biennially (beginning in
June 2001) and were not sampled during this monitoring event.
Groundwater samples are collected semiannually and analyzed for all constituents listed in 40 CFR
Part 258, Appendix I, incorporated by reference into the NCSWMR (North Carolina (NC) Appendix I) and
for 1,4-dioxane in accordance with the NCDEQ-SWS May 29, 2018 memorandum. The following table
summarizes the Areas I-IV monitoring well classifications and monitoring zones. The well locations are
shown on Drawing 1 and a summary of well construction details is included in Appendix 1.

2.2 Closed Landfill Area V Monitoring Program
The current groundwater monitoring network at the Closed Landfill Area V consists of one upgradient
background well (7901-MW1A) and three downgradient wells (7901-MW5, 7901-MW9, and
7901-MW11). In addition, monitoring well 7901-MW2A is used as an observation well. Note that there
are two monitoring wells designated MW11 at the Facility: one associated with Area V (Permit 7901)
and one associated with the Subtitle D Landfill (Permit 7904). The monitoring well associated with
Area V is referred to as 7901-MW11 and the monitoring well associated with Subtitle D Landfill is
referred to as 7904-MW11.
Groundwater samples are collected semiannually and analyzed for all constituents listed in NC
Appendix I and for 1,4 dioxane in accordance with the NCDEQ-SWS May 29, 2018 memorandum. Also,
monitoring wells 7901-MW9 and 7901-MW11 are monitored for detected Appendix II constituents,

mercury and tin, and monitoring well 7901-MW9 is also analyzed for dichlorodifluoromethane.
Monitoring well classification and monitoring zones are summarized below. The well locations are
shown on Drawing 1 and a summary of well construction details is included in Appendix 1.
Nature and extent well 7901-NES1 was installed in 2004 in response to exceedances observed in
several wells associated with this area and was monitored until June 2010, when monitoring of this
well was suspended. In a letter dated March 22, 2018, the NCDEQ-SWS requested Rockingham
County to resume monitoring of 7901-NES1 for Appendix I constituents and 1,4-dioxane.

Twenty-five active groundwater monitoring wells comprise the monitoring network at the Rockingham
County Subtitle D Landfill. The current compliance monitoring wells network is listed in the table below
and the approximate locations are depicted in Drawing 1. A summary of well construction details is
included in Appendix 1.
The Subtitle D Area’s monitoring wells, except for monitoring wells 7904-MW19 and 7904-MW19R,
are monitored under Detection Monitoring. Groundwater samples are collected semiannually and
analyzed for all constituents listed NC Appendix I and for 1,4-dioxane per the NCDEQ-SWS May 29,
2018 memorandum.
Monitoring well 7904-MW19R is monitored under Assessment Monitoring and samples from this
monitoring well are analyzed for the full NCSWMR Appendix II list annually (during the first semiannual
event of each year). Also, it is analyzed for the NCSWMR Appendix I list plus detected NCSWMR
Appendix II constituents during the second semiannual event of each year. It is also sampled for
1,4-dioxane following the NCDEQ-SWS May 29, 2018 memorandum during both events. In addition,
monitoring well 7904-MW19R samples are analyzed for methane, ethane, ethene, and dissolved carbon dioxide during both semiannual events. Monitoring well 7904-MW19 is a corrective action
performance well and will be sampled for the Facility’s list of constituents of concern (COC). The
current COC list includes:
• Benzene,
• 1,2-Dichloroethane,
• Vinyl Chloride,
• Arsenic, and
• Cobalt.
On March 6, and 7, 2019, monitoring wells 7904-MW20S, 7904-MW20D, 7904-MW21, and
7904-MW23 were abandoned to allow for the construction of a new cell (Phase 4). On March 11 and

12, 2019, monitoring wells 7904-MW21R and 7904-MW23R were installed as a part of the
compliance network and are monitored under Detection Monitoring.
During the summer of 2020, the Facility completed a hydrogeological study as part of the Life-of-Site
(LOS) Application for future Phases 5 through 7. The hydrogeological study included the installation of
five groundwater monitoring wells (7904-MW24 through 7904-MW28), which are now part of the
Subtitle D landfill’s monitoring network. Groundwater samples from these monitoring wells were
analyzed for all constituents listed in NC Appendix I and for 1,4-dioxane as part of the monitoring well
baseline sampling.

3.0 SEPTEMBER 2023 MONITORING EVENT
3.1 Field Work
LaBella personnel visited the Facility on September 25-29, 2023, and October 3, 2023 (September 2023 Monitoring Event) to obtain water levels to the nearest 0.01-foot, purge, and sample monitoring
wells in the compliance network at Areas I-IV, Area V, and Subtitle D Landfills.
Four surface water monitoring points and one leachate monitoring point were also sampled during the
September 2023 Monitoring Event. In addition, depth-to-water measurements were obtained at
monitoring wells 7901-MW3A, 7904-MW8, 7904-MW9, and 7904-MW22, which are not part of the
compliance network.
Monitoring wells were purged and sampled using disposable bailers or a 12-volt submersible pump
during the September 2023 Monitoring Event. Monitoring wells 7904-MW24, 7904-MW25,
7904-MW26, 7904-MW27, and 7904-MW28, were purged following minimal drawdown (low-flow)
groundwater sampling procedures. The 12-volt submersible pump was decontaminated with Alconox
liquid detergent and deionized water after each monitoring well that required the use of the pump and
an equipment blank was collected and analyzed.
Measurements of temperature, pH, specific conductivity, dissolved oxygen, oxidation-reduction
potential, and turbidity were recorded before purging, after each purge volume, and during sampling.
Copies of the groundwater sampling logs are included in Appendix 2. Prior to sampling, laboratory-
supplied containers were prepared with the following information:
• Monitoring well number (completed by field personnel);
• Date and time of sample collection (completed by field personnel);
• Initials of sampling personnel (completed by field personnel);
• Project name and number (completed by the laboratory),
• Chemical preservative (completed by the laboratory); and
• Requested chemical analysis (completed by the laboratory).
During the monitoring event, groundwater samples from each sampled monitoring well were collected
directly from the bailers or from the pump discharge tubing and transferred to the provided laboratory
containers within 24 hours of the final purge volume. Immediately after collection, the samples were
placed in a laboratory-provided cooler and chilled on ice.
Surface water samples 7904-SMP1 through 7904-SMP4 were collected directly from streamflow by
lowering the prepared sample containers into the stream. Care was taken not to overflow the sample
containers (which could lead to preservative loss) and to avoid sampling-induced turbidity. At the time
of sampling, surface water was also measured for temperature, pH, specific conductivity, dissolved
oxygen, oxidation-reduction potential, and turbidity. Copies of the surface water sampling logs are
included in Appendix 2. After collection, the samples were placed in a laboratory-provided cooler and
chilled on ice.
Leachate samples were collected from the leachate lagoon by lowering a disposable bailer into the
lagoon and then dispensing the leachate into laboratory-prepared sample containers. The prepared

sample containers were then placed in a cooler and chilled on ice. At the time of sampling, leachate
was measured for temperature, pH, specific conductivity, dissolved oxygen, oxidation-reduction
potential, and turbidity.
3.2 Laboratory Analysis and Quality Control
The collected groundwater, surface water, and leachate samples were submitted to Eurofins
Environmental Testing (Eurofins) of Cary, North Carolina under chain-of-custody control for analysis.
LaBella requested a Level II data report for the final laboratory reports. According to the laboratory’s
sample condition and verification reports, the samples were received by the laboratory on October 3,
2023, in good condition, properly preserved, and within analysis hold times.
An equipment blank was collected by LaBella personnel as part of the monitoring event. To collect the
equipment blank, laboratory-provided deionized water was run through the decontaminated 12-volt
submersible pump, and the samples were collected directly from the pump discharge tubing. A field
blank was collected using laboratory-supplied distilled water exposed to the sampling environment
during the September 2023 Monitoring Event. A trip blank was also prepared by the laboratory to
accompany the volatile sampling containers during shipment. The equipment blank and field blank
were analyzed for NC Appendix I constituents, mercury, methane, ethane, ethene, dissolved carbon
dioxide, tin, trichlorofluoromethane, and 1,4-dioxane, while the trip blank was analyzed for NC
Appendix I volatile organic compounds, trichlorofluoromethane, and 1,4-dioxane.
Upon receipt of complete laboratory data packages on October 17, 2023, LaBella personnel reviewed
the data for the following:
• General typographical errors,
• correct analyses performed and within method specified hold times,
• biased data results based on Surrogate Recoveries, Matrix Spike, Matrix Spike
Duplicate, and Laboratory Control Samples,
• blank-qualified data (B-flags),
• detections above the Method Reporting Limits (MRL),
• exceedances of 15A NCAC 2L.0202 (NC2L) Groundwater Standards,
• exceedances of approved background values,
• exceedances of 15A NCAC 2B (NC2B) Surface Water Standards or In-stream
Target Values (ISTV), and/or
• detections that are above historical levels.
Copies of the laboratory analytical packages, including their respective chains of custody, are included
in Appendix 2.

4.0 HYDROGEOLOGY
Depth to groundwater was measured in each monitoring well at the site before purging. The
groundwater elevation at each well was calculated relative to the surveyed measuring point (top of casing) for each monitoring well. Table 1 summarizes the groundwater elevations.
Groundwater elevation contours were interpreted from water level data obtained during the
September 2023 Monitoring Event and a potentiometric surface map was created. Based on LaBella’s
interpretation, the groundwater flow paths across the Facility appear to converge on the streams that
bisect the site and border it to the west-northwest. Groundwater flow beneath the closed Area I-IV
Landfills is predominantly to the south. Groundwater flow beneath the closed Area V landfill is
predominantly to the southwest. Conversely, groundwater flow beneath the Subtitle D Area Landfill is
radial from the southeast to the northwest and west. Both groundwater flows (Area I-V) and Subtitle
D) appears to converge in the northwest corner of the Facility. The potentiometric surface contours
for groundwater are shown in Drawing 1.
Horizontal groundwater gradients were estimated based on the September 2023 groundwater
contours. Groundwater gradients were estimated from groundwater flow arrow segments that
intersect potentiometric surface contours (see Drawing 1). These gradients are summarized in
Table 2. The horizontal gradients were calculated as approximately 0.045 for Closed Areas I-IV, 0.042
for Closed Area V, and 0.039 for the Subtitle D area.
The average hydraulic conductivity (K) estimates from individual well slug tests (CDM, 1996; JOYCE,
2007; LaBella, 2021) were used to estimate average linear groundwater flow velocities. Effective
porosity was estimated at 0.20 for saprolite and 0.05 for fractured bedrock (CDM, 1996). Linear
groundwater flow velocities for wells screened in saprolite were computed using the following modified
Darcy equation:
V = Ki/n,
Where;
V = average linear velocity (feet/day),
K = hydraulic conductivity (ft/day),
i = horizontal hydraulic gradient, and
n = effective porosity.
As shown in Table 2, the linear groundwater flow velocity estimates are approximately 0.29 ft/day in
Areas I-IV, 0.34 ft/day in Area V, and 0.029 ft/day in the Subtitle D area. These ranges are consistent
with previously estimated values (CDM, 1996; JOYCE, 2007; LaBella, 2021).
The linear velocity equation and resulting rates make the simplified assumptions of a homogeneous
and isotropic aquifer. Site boring logs indicate that saprolite sampled at the site often exhibited
remnant foliation and other parent rock textures. These characteristics can impact locally anisotropic
groundwater flow directions. The saprolite and bedrock are hydraulically connected, but effective
porosity typically declines markedly downward into underlying fractured bedrock (Harned, 1989).

5.0 DATA ANALYSIS AND STATISTICAL RESULTS
Analytical results from the September 2023 Monitoring Event were received on October 17, 2023,
from Eurofins. The analytical reports are included in Appendix 2.
Statistical comparisons of baseline monitoring data to compliance groundwater data are optional
[NCSWMR .1632(g), (h), and (i)] for the Detection Monitoring wells at the Area V and Subtitle D
Landfills. Statistical methods used to evaluate the data from Area V Landfill and Subtitle D Landfill
are discussed in the following sections, if needed. This is done to compare the results of the current
monitoring event to background data. For the September 2023 Monitoring Event, the laboratory
analytical results were compared directly to the NC2L standard, or previously approved background
values; therefore, statistical calculations were not required.
5.1 Analytical Results and Comparisons to Standards
5.1.1 Permit 79-01
5.1.1.1 Closed Landfill Areas I-V Detections
The constituents listed in Table 3 were detected at concentrations above the method detection limit
(MDL) during the September 2023 Monitoring Event. Detections above the approved background
concentration, or NC2L Standard are shown in Table 4.
The historical inorganic and organic analytical results for Areas I-IV are included in Table A3-1
(Appendix 3). The September 2023 Monitoring Event field parameters are summarized in Table 5.
The analytical results as reported by the laboratory, the laboratory quality assurance/quality control
information, and the chains of custody are included in Appendix 2.
The Facility has an approved Alternate Source Demonstration (ASD) for cobalt and arsenic, with an
addendum dated August 30, 2018, which established a cobalt background concentration of 34.6
micrograms per liter (µg/L) and an arsenic background concentration of 14.08 µg/L; therefore, these
concentrations are used as the groundwater protection standards for cobalt and arsenic, respectively.
5.1.1.2 Closed Landfill Areas I-V Exceedances
After comparing the detected constituents to their respective background concentration or NC2L
standard, it was determined that the following parameters were in exceedance of their respective
standard:
• 1,4-Dichlorobenzene (7901-MW9)
• 1,4-Dioxane and Benzene (7901-MW6, 7901-MW7, 7901-MW9)
• Tetrachloroethene (7901-MW11)
• Vinyl Chloride (7901-MW6, 7901-MW9)
Detections above the background concentration or NC2L are shown in Table 4.

5.1.2 Permit 79-04
5.1.2.1 Subtitle D Landfill Detections
The constituents listed in Table 3 were detected above the MDL in groundwater during the September
2023 Monitoring Event for the Subtitle D Landfill. Detections in compliance wells 7904-MW24, 7904-
MW25, 7904-MW26, 7904-MW27, and 7904-MW28 represent baseline concentrations. The Facility
has an approved ASD for arsenic and cobalt, with an addendum dated August 30, 2018, which
established background concentrations of 14.08 µg/L and 34.6 µg/L, respectively.
The historical inorganic and organic analytical results for the Subtitle D Landfill are summarized in
Table A3-3 (Appendix 3). Field parameters for the September 2023 Monitoring Event are summarized
in Table 5. The analytical results, as reported by the laboratory, the laboratory quality
assurance/quality control information, and the chains of custody are included in Appendix 2.
5.1.2.2 Subtitle D Landfill Exceedances
Of the detections listed in Table 3, the only constituents with confirmed exceedances of their
respective background concentrations or NC2L standards include:
• Arsenic (7904-MW17D)
• Cobalt (7904-MW19 and 7904-MW19R)
• Vinyl chloride (7904-MW5D)
The analytical report for the monitoring event is included in Appendix 2.
The above analytes were detected above their respective NC2L standards or their approved
background concentrations; however, the results are consistent with historical data.
Groundwater remediation consisting of landfill gas extraction is ongoing to reduce cobalt levels in
7904-MW19 and 7904-MW19R to background levels. During the partial closure of Phases 1 to 3 of
the Subtitle D landfill, which disrupted the operation of the remedial system, an increase in cobalt
concentration was observed (see Table A3-3). After the restart of the operation of the remedial system,
a reduction of cobalt concentrations is expected. Detections above the NC2L or background are shown
in Table 4.
5.1.3 Surface Water
There were no inorganic constituents detected at quantified concentrations above NC2B or ISTV
standards during the September 2023 Monitoring Event. Beryllium (in 7904-SMP4) was the only
organic constituent detected above its NC2B standard in any of the surface water monitoring points.
Note that estimated concentrations below the MRL are not considered exceedances of the standard,
even if the estimated value is higher than the standard. Table 3 includes the constituents detected in
surface water above the MDL during the September 2023 Monitoring Event. The historical inorganic
and organic analytical results for surface water are summarized in Table A3-4 (Appendix 3). Field
parameters for the September 2023 Monitoring Event are summarized in Table 5. The analytical
results as reported by the laboratory, the laboratory quality assurance/quality control information and the chains of custody are included in Appendix 2.

5.1.4 Leachate
Table 3 includes the constituents detected in the leachate sample 7904-LMP1 above the MDL during
the September 2023 Monitoring Event. The historical inorganic and organic analytical results for the
leachate lagoon are summarized in Table A3-5 (Appendix 3). The results, as reported by the laboratory,
the laboratory quality assurance/quality control information, and the chains of custody record are
included in Appendix 2.
5.2 Statistical Results
No new statistical analyses were conducted for this event.
6.0 CONCLUSIONS
6.1 Permit 79-01 - Closed Areas I-V
The only constituents reported above NC2L standards were:
• 1,4-Dichlorobenzene (7901-MW9)
• 1,4-Dioxane and Benzene (7901-MW6, 7901-MW7, 7901-MW9)
• Tetrachloroethene (7901-MW11)
• Vinyl chloride (7901-MW6, 7901-MW9)
These exceedances are generally consistent with historical results.
In general, the historical data for Areas I-IV indicate decreasing trends over time and it appears that
the constituent impact area is limited and is not migrating off-site. This is evident in Chart A4-1
(Appendix 4), as the trend lines for tetrachloroethene, vinyl chloride, and benzene have a negative
slope.
The analytical results for Area V are consistent with historical results, and a review of the historical
data suggests a slightly decreasing trend in the benzene and tetrachloroethene concentrations over
time. These trends are evident in Chart A4-2 (Appendix 4). Based on the analytical results, the
interpretation of the September 2023 Monitoring Event data in comparison to historical trends, and hydrology and site conditions, Permit 79-01 Closed Areas I-IV and Closed Area V will continue to be
monitored as outlined in Title 15A NCAC 13B .0500 and .1633, respectively, and the approved WQMP.
6.2 Subtitle D Area
The constituents reported above their respective NC2L standard for the Subtitle D Area are:
• Arsenic (7904-MW17D)
• Cobalt; (7904-MW19 and 7904-MW19R)
• Vinyl Chloride (7904-MW5D)
The Facility has an approved ASD (August 30, 2018) for cobalt and arsenic, which established a cobalt
background concentration of 34.6 µg/L and an arsenic background concentration of 14.08 µg/L;
therefore, these concentrations are used as the groundwater protection standards for cobalt and
arsenic, respectively.

Though the concentrations of arsenic in 7904-MW17D (32.4 µg/L) and cobalt in 7904-MW19 (141
µg/L), and 7904-MW19R (169 µg/L) are greater than the site background concentrations, the results
are consistent with historical data. As shown in Chart A4-3, arsenic concentrations appear to fluctuate seasonally in monitoring well 7904-MW17D.
Based on the analytical results from the September 2023 Monitoring Event, the interpretation of the
data in comparison to historical trends, hydrology, and site conditions, the Subtitle D Landfill will
continue to be monitored as outlined in Title 15A NCAC 13B .1633 and the approved WQMP.

DL = Laboratory detection limit. MW = Groundwater monitoring well. QL = Quantiation limit J = Estimated value between DL and SWSL. B = Blank qualified detections. ND = Not detected above laboratory reporting limit (October 1996 - June 2006). Not detected above the laboratory detection limit (December 2006 - Present). '--- = Not Sampled and/or Not Reported. NI = Not Installed. An NI designation indicates the well was not installed, exterior well construction not complete, not developed, or prior to background sampling. NC 2L = North Carolina 2L Groundwater Standard. GWPS = Groundwater Protection Standard. Bold values are above the NC 2L Groundwater Standard or Groundwater Protection Standard (GWPS). When the NC 2L Standard has not been established, the GWPS will substitute. { } = When Method Blank concentrations are higher than Trip or Field (Equipment) Blank concentrations and there are multiple Method Blanks for a sample set, use the brackets to assign Method Blank data to specific data sets.Additional Parameters for LFG Impact monitoringRockingham County Solid Waste Management FacilityPermit Nos. 79-01 and 79-04 Page 24 of 24 LaBella Associates

All concentrations are in µg/L.
MW = groundwater monitoring well
ND = not detected above laboratory reporting limit (September 1993 - June 2006). Not detected above the laboratory detection limit (December 2006 - Present).
QL = Quantation limit
DL = laboratory detection limit
NA = Not available.
J = estimated value between DL and RL
* constituent is on NC Appendix II list and not on NC Appendix I list
NC 2L = North Carolina 2L Groundwater Standard.
GWPS = Groundwater Protection Standard.
Bold values are above the NC 2L Standards or Groundwater Protection Standards (GWPS).
When NC 2L Groundwater Standard has not been established, the GWPS will be used.
Values in parenthesis next to a value are results of a duplicate sample.
B = Blank qualified detections.
--- = Monitoring well not monitored or not monitored for specific constituent.
NR = Not reported.
NI = Not installed.
NS = Not sampled.
{ } = When Method Blank concentrations are higher than Trip or Field (Equipment) Blank concentrations and there are multiple Method Blanks for a sample set, use the brackets to assign Method Blank data to specific data
sets.
