1 INTRODUCTION AND BACKGROUND
___________________________________________________________________________________
1.1 INTRODUCTION
The Salt Lake Valley Solid Waste Management Facility (SLVSWMF or Landfill) is located at 6030 West
California Avenue (1300 South) in Salt Lake County, Salt Lake City, Utah (the Site). The Fall 2024 leachate
monitoring was performed in accordance with the Salt Lake County Health Department (SLCHD),
formerly the Salt Lake Valley Health Department, Health Regulation Number 1, and the scope of services
associated with the Salt Lake County contract #SWM12121 (dated April 16, 2021). The following report
summarizes the Fall 2024 leachate monitoring conducted at the SLVSWMF.
1.2 BACKGROUND
Monitoring and sampling of leachate within the modules located at the Active Landfill Area of the
SLVSWMF has been performed since 1993 and is currently performed on a semi-annual basis. Leachate
monitoring involves measuring levels of the leachate in the risers to inform Landfill staff regarding
leachate removal requirements and to collect data to assess potential leachate impacts to the
groundwater beneath the Landfill.
A sump and riser for measuring, sampling, and removing leachate is located at the lowest topographic
point in each of the seven in-use Landfill modules and is built such that the bottom of the sump is
approximately five feet below the module liner. A conductivity-based oil/water interface probe is then
lowered down the length of the riser, and both depth-to-leachate and total depth of the riser are
measured.
into leachate collection ponds to maintain leachate levels within the lined portion of the Landfill.
Historically, leachate levels were measured, and samples were collected from seven (7) leachate riser
sumps located in the seven (7) lined and in-use modules (i.e., one leachate riser per module) within the
SLVSWMF. The SLCHD and the Utah Department of Environmental Quality Division of Waste
Management and Radiation Control (DWMRC) were petitioned on April 23, 2009 (Kleinfelder Document:
SLC9L185) to reduce the number of leachate risers sampled during each semi-annual sampling event
from seven to two since the landfill has been designed to have a hydraulic gradient toward the middle of
the landfill (toward Modules 6 and 7). Leachate levels were proposed to be monitored in each of the
seven risers located in the Active Landfill Area as part of the requested modification to the leachate
monitoring plan. The proposed modification was subsequently approved by SLCHD in a letter dated
25000032.001A/SLC24R175245 Page 2 of 11 December 6, 2024
© 2024 Kleinfelder www.kleinfelder.com
July 15, 2009, and since that time, leachate levels have been recorded in all seven risers, while leachate
samples are only collected from the risers installed in Modules 6 and 7. The location of the leachate
risers is shown on Figure 1.

2 LEACHATE ASSESSMENT
___________________________________________________________________________________
2.1 LEACHATE MEASUREMENTS
On October 18, 2024, Kleinfelder measured leachate levels in six (6) leachate risers within Modules 1
through 7 (S-1 through S-7), excluding riser five (S-5). Leachate Riser S-5 was abandoned in 2024 and the
remaining leachate risers were shortened for easier monitoring access. See Figure 1 for the historical
location of leachate Riser 5. Free-phase hydrocarbons were not detected with the interface probe in the
six (6) leachate risers. The calculated leachate thicknesses ranged from 0.25 feet in Riser S-4 to 6.75 feet
in Riser S-2.
Table 1 presents a summary of the leachate riser inspection data, including depths from the top of the
leachate risers to the top of the leachate, the total depth of each leachate sump, and leachate thickness
in each of the sumps.
2.2 LEACHATE SAMPLING AND ANALYSIS
On October 18, 2024, Kleinfelder personnel collected samples from leachate Risers S-6 and S-7, including
a duplicate sample (DUP-1) from Riser S-6 for quality assurance purposes. Laboratory-provided leachate
sample bottles were filled from each leachate riser using a disposable bailer. Immediately following
sample collection, the sample bottles were labeled and placed on ice within the laboratory-provided
cooler. Kleinfelder recorded sampling data on Field Data Sheets, copies of which are included in
Appendix A.
The samples were transported under chain-of-custody documentation to Pace National Center for
Testing and Innovation (Pace) in Mt. Juliet, Tennessee for analysis of the compounds and constituents
listed in Table 2, as required by SLCHD Health Regulation Number 1.
2.3 LEACHATE ANALYTICAL RESULTS
The leachate samples were analyzed for organic and inorganic parameters. A copy of the laboratory
analytical report is included in Appendix B. A summary of select analytical data collected at the Landfill
since 2020 is presented in Table 3 (volatile organic compounds) and Table 4 (inorganic compounds).
Historical analytical results prior to 2020 are included in the prior reports and can be provided upon
request. A summary of the Fall 2024 analytical results is presented below.

aluminum,
calcium,
copper,
lead,
manganese,
selenium, and
zinc.
As shown in Table 4, the reported concentrations of metals in the samples collected during the Fall 2024
leachate monitoring event are similar to historical concentrations of metals reported in samples
collected from the leachate in Risers S-6 and S-7.
2.3.3 Other Compounds
The laboratory reported concentrations above the laboratory RDL of the following compounds in one or
both leachate samples submitted for laboratory analysis:
alkalinity as ,
ammonia as nitrogen,
bicarbonate as ,

total organic carbon (TOC), and
total organic halides (TOX).
Highly soluble minerals and other compounds without an established Solid Waste Groundwater Quality
Protection Standards (SWGQPS) are included in the leachate analysis to assess whether the leachate
held within the lined Landfill area is entering groundwater beneath the Landfill. The laboratory reported
concentrations of nitrate, nitrite, and sulfate generally greater than those in the historical dataset for
25000032.001A/SLC24R175245 Page 7 of 11 December 6, 2024
© 2024 Kleinfelder www.kleinfelder.com
the leachate collected from Riser S-6. The laboratory also reported concentrations of alkalinity as
CaCO3, ammonia as nitrogen, bicarbonate as CaHCO3, COD, nitrate as nitrogen, sulfate, and TKN, and
TOC generally greater than those in the historical dataset for the leachate collected from Riser S-7.
Current and historical laboratory results are shown in Table 4.
2.4 QUALITY CONTROL
As part of internal quality assurance and quality control (QA/QC), a trip blank and duplicate
sample were submitted for laboratory analysis. Additionally, Pace performed internal QA/QC, including
method blank (MB), matrix spike/matrix spike duplicate (MS/MSD), and laboratory control sample (LCS)
in the laboratory analytical report (Appendix B). The
following list summarizes the QA/QC results:
Qualifiers were listed in the laboratory report L1790878 with sample IDs: S- 7 and S- 6.
In the sample DUP-1, lead, zinc, benzene, 1,4-dichlorobenzene, ethylbenzene, toluene, and total
an estimate.
In the sample DUP-1, toluene-recovery
limits have been exceeded and the values are outside the upper control limits.
In the sample S-6, total phenol, benzene, carbon disulfide, 1,4-dichlorobenzene, 1,2-
indicating that the reported value of the analyte is an estimate.
In the sample S-6, S-7, and DUP-1, bromomethane, trans-1,4-dichloro-2-butene, iodomethane,
2- the associated batch QC
was outside the established quality control range for precision.
In the sample S-6, S-7, and DUP-
sample was received past the holding time expiration.
In the sample S-7, sulfate, aluminum, calcium, copper, lead, manganese, selenium, zinc,
acetone, carbon disulfide, carbon tetrachloride, 1,1-dichloroethane, 1,2-dichloroethene, and
1,2-he reported value of
the analyte is an estimate.
25000032.001A/SLC24R175245 Page 8 of 11 December 6, 2024
© 2024 Kleinfelder www.kleinfelder.com
One trip blank was kept with the S-6, S-7, and DUP-1 sample containers during sampling activities and in
transit to Pace. The trip blank was analyzed for VOCs to check for cross contamination of the leachate
samples. No VOCs were reported by the laboratory above their respective RDLs in the trip blank.
Surrogate compounds are substances intentionally added by the laboratory in known quantities to
determine the analytical stability and possible sample matrix effects. Surrogate compounds are chosen
for their rareness in the environment and their similarity to the target analytes in the method. Surrogate
recoveries were also within the established laboratory limits.
The MS/MSD results indicate acceptable recoveries, with most compounds within acceptable percent
recovery limits and relative percent difference (RPD) limits, designated by the laboratory. The LCS/LCSD
results indicate acceptable recoveries, with most compounds within percent recovery limits and RPD
limits, designated by the laboratory.
To assess data quality, a duplicate was collected from S-6 (sample ID DUP-1) and submitted to the
laboratory for analysis of the analytes listed on Table 2. A summary indicating the RPDs between the
primary and duplicate sample is provided as Table 5. The calculated RPDs were within the United States
EPA) precision guideline of 20% for aqueous samples (EPA, 2002) for
all analytes, except for manganese and calcium. Due to the high turbidity generated by use of the bailer,
and the variability of the leachate, some exceptions to the precision guideline are to be expected and
have been observed historically.
In general, the data reported by the laboratory is considered valid and usable.

3 CONCLUSIONS
___________________________________________________________________________________
Kleinfelder measured leachate levels in leachate Risers S-1 through S-7, excluding S-5, and collected
samples from the leachate risers located within Module 6 and Module 7 on October 18, 2024.
The calculated leachate thicknesses ranged from 0.25 feet in Riser S-4 to 6.75 feet in Riser S-2.
Kleinfelder compared the results of the Fall 2024 L
network, and although several inorganic compounds were identified in both the leachate samples and
the groundwater samples collected, no VOCs or analytes with SWGQPS were detected in the down
gradient groundwater monitoring wells in the Active Landfill at concentrations exceeding their
respective SWGQPS or RDL. Therefore, it does not appear that leachate located within the Landfill liner
is leaking to the local groundwater.
The next leachate monitoring event is scheduled for Spring 2025.

= Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations
should be considered minimum values.
= The sample was recieved past or too close to holding time expiration.
= The sample matrix interfered with the ability to make any accurate determination; spike value is
low.
= The same analyte is found in the associated blank.
= The associated batch QC was outside the established quality control range for accuracy.
= Analytical holding time was exceeded.
= The blank depletion was greater than the recommended maximum epletion of 0.2 mg/L.
= Test replicates show more than 30% difference betweeen high and low value.
= The associated batch QC was outsie the lower control limits; associated data has a potential negative
bias.
Dissolved Oxygen (mg/L)
= The identification of the analyte is acceptable; the reported value is an estimate.
