Dear Mr. Rahman:
On behalf of the Town of Southold, please findenclosed one electronic copy of the following document
for your review:
Post Closure Groundwater Monitoring Program
First Semiannual Report of 2022
s petition to reduce the scope and
frequency of post-closure groundwater monitoring to semiannually for Part 360 Baseline Parameters. The
FirstSemiannual 2022 results discussed in the enclosed report are generally consistent with previous
sampling eventsand do not indicate any significant changes or deterioration in groundwater quality that
would warrant a change in the scope of the monitoring program. Therefore, the monitoring reduction
approved by NYSDEC should be continued. The next monitoring round(Second Semiannual 2022
groundwater monitoring event) is scheduled to be conducted in the fourth quarter of 2022 for Part 363
Baseline Parameters.
If you should have any questions, please do not hesitate to contact me at (516)364-9890, Ext.3058.

1.0 INTRODUCTION
The Town of Southold has retained D&B Engineers and Architects (D&B) to perform
post-closure groundwater monitoring and reporting for the closed and capped municipal solid
waste (MSW) landfill in Cutchogue, New York (i.e., the Site). The location of the Site is shown
in Figure 1-1. This report documents the results of the Semi-annual groundwater monitoring
event conducted on June 6, 2022, and describes the work performed and the results obtained. The
groundwater monitoring wells were sampled in strict conformance with the Quality
Assurance/Quality Control (QA/QC) Plan, which is part of the Post Closure Monitoring and
Maintenance Manual, dated August 2003.
In the past, groundwater sampling was performed quarterly, with three rounds analyzed
for New York Codes, Rules and Regulations (NYCRR) Part 360 Routine Parameters and one
round analyzed for 6 NYCRR Part 360 Baseline Parameters on a rotating basis. In the Spring of
2015, on behalf of the Town of Southold, D&B proposed modifications to the New York State
Department of Environmental Conservation (NYSDEC) pertaining to the sampling frequency
and analyses for the Post-Closure Groundwater Monitoring Program for the Site. The request for
these modifications was approved by the NYSDEC on July 2, 2015. Modifications to the Post-
Closure Groundwater Monitoring Program included:
A reduction in sampling frequency from quarterly to semi-annually for all well
clusters (MW-1, MW-3, MW-4, MW-5, MW-6 and MW-8); and
Groundwater analysis for 6 NYCRR Part 360 Baseline Parameters for both Semi-
annual sampling events.
This report is organized into the following sections: Section 2.0 (Sampling Procedures
and Analyses) describes the water level measurements and groundwater sampling procedures, as
well as the groundwater analyses; Section 3.0 (Groundwater Level Measurements) summarizes
the groundwater level measurements and groundwater elevations; Section 4.0 (Discussion of
Results) summarizes the key findings from this groundwater monitoring event, including

2.0 SAMPLING PROCEDURES AND ANALYSES
monitoring wells (MW-1S, MW-1D, MW-3S, MW-3D, MW-4S, MW-4D, MW-5S, MW-5D,
MW-6S, MW-6D, MW-8S and MW-8D) on June 6, 2022, as part of this Semi-annual 2022
groundwater monitoring event. A site plan showing the locations of the monitoring wells is
provided in Figure 2-1. The following sections provide a brief discussion of the procedures used
during groundwater level measurements, groundwater sampling and sample analysis.
2.1 Groundwater Level Measurement Procedures
Water level measurements were obtained from the 12 monitoring wells to determine the
volume of standing water in the well for purposes of purging, as well as for determination of
groundwater elevations and flow direction. Groundwater level measurements were obtained from
a surveyed measuring point on each well utilizing a decontaminated electronic water level
indicator to an accuracy of 0.01 foot. A discussion regarding groundwater level measurements
and groundwater flow direction is provided in Section 3.0.
2.2 Groundwater Sampling Procedures
Sampling procedures for the collection of the groundwater samples were implemented in
accordance with the protocol described in the Quality Assurance/Quality Control (QA/QC) Plan,
which is part of the Post Closure Monitoring and Maintenance Manual, dated August 2003. Field
decontamination was performed between sampling locations for non-disposable equipment.
Prior to collecting groundwater samples, the 12 monitoring wells were purged to remove
the standing water in each well. Well purging was accomplished by first measuring the static
water level in the well and then calculating the volume of standing water. A decontaminated
submersible pump and dedicated low density polyethylene tubing was used to purge the water
from the well. Decontamination of the submersible pump used for well purging was performed
in accordance with the procedure described in the QA/QC Plan.

During the purging process, groundwater was monitored and recorded for the following
field parameters: pH, temperature, specific conductance, oxidation reduction potential (ORP),
dissolved oxygen and turbidity. When the values of the field parameters stabilized to within 10%
based on the last two readings, the turbidity of the groundwater was less than 50 Nephelometric
Turbidity Units (NTUs), and at least three well volumes had been removed, well purging was
considered complete.
In accordance with the QA/QC Plan, groundwater samples were collected using new,
dedicated, disposable polyethylene bailers and polypropylene rope. Samples for VOC analysis
were collected first, followed by inorganic parameters and leachate indicators. Each sample was
labeled with the well number, time, and date, stored in an ice-filled cooler with the chain of
custody forms, and delivered to the laboratory (Pace Analytical Services, Inc.).
Appropriate quality assurance/quality control (QA/QC) samples, which included matrix
spike and matrix spike duplicate (MS/MSD) sets and a trip blank were collected in accordance
with the QA/QC Plan.
Tables summarizing the analytical results are provided in Appendix A and are discussed
in Section 4.0. Groundwater sampling logs for this Semi-annual 2022 groundwater monitoring
event are provided in Appendix B, and the chain of custody forms are provided in Appendix C.
2.3 Sample Analyses
Groundwater samples collected during this Semi-annual 2022 groundwater monitoring
event from the 12 monitoring wells were analyzed for 6 NYCRR Part 363 Baseline Parameters.
Laboratory analyses were performed by Pace Analytical Services, Inc., located in Melville, New
York. This laboratory is approved under the New York State Department of Health
Environmental Laboratory Approval Program (ELAP) for the analyses performed.

3.0 GROUNDWATER LEVEL MEASUREMENTS
Groundwater level measurements were collected by D&B on June 6, 2022, from the 12
groundwater monitoring wells as part of this Semi-annual 2022 groundwater monitoring event.
The groundwater level measurements from the monitoring wells are summarized in Table 3-1.
As shown in Table 3-1, water table elevationhe Site
ranged from 6.99 feet above mean sea level (MSL) in well MW-1S, located on the south end of
the Site, to 4.91 feet above MSL in well MW-8S, located on the west side of the Site. Based
upon the June 6, 2022, groundwater level measurements and calculated water table elevations,
groundwater flow direction was determined to be in a north-northwesterly direction. Therefore,
well cluster MW-1 is located upgradient of the Site, and the other wells are located along the
downgradient boundary of the Site.
Potentiometric surface elevations in the deep (ells at the Site are generally
consistent with the shallow well water table elevations, except for well MW-8D, and indicate no
substantial vertical hydraulic gradient throughout the landfill site. An upward vertical hydraulic
gradient is indicated at well cluster MW-8, due to the lower water table elevation.

4.0 DISCUSSION OF RESULTS
4.1 Data Validation
Twelve groundwater samples, one matrix spike/matrix spike duplicate (MS/MSD), and
one trip blank were collected as part of the June 2022 Sampling Event performed at Town of
Southold Landfill. All samples were analyzed for the 6 NYCRR Part 363 Baseline Parameters,
including volatile organic compounds (VOCs), inorganic parameters (metals) and leachate
indicators. Sample analysis was performed in accordance with SW-846 methods. The laboratory
analyses were performed by Pace Analytical Services, LLC, Melville, New York and reported in
data package 70217263.
The data package (70217263) submitted by the analytical laboratory was validated in
accordance with NYSDEC quality assurance/quality control (QA/QC) requirements, the contract
requirements and Part 363. All samples were analyzed within the method specified holding times
except where noted below. The following requirements were outside limits and required
qualification of the data:
The following were detected in the preparation blank and qualified as non-detect
(UB): aluminum in sample MW-6S and mercury in all samples.
The %R (percent recovery) was below the QC limit in the spike and post digestive
spike for silver. Silver was qualified as an estimated limit (UJ) in all samples.
The holding times were exceeded for hexavalent chromium and was qualified as an
estimated detection limit (UJ) in all samples.
Sulfate and nitrite were detected in the method blank. Nitrite was qualified as non-
detect (UB) in samples MW-4S, MW-6D, and MW8S.
The relative percent difference (RPD) was above the QC limit in the laboratory
duplicate for total dissolved solids associated with all samples and it was qualified as
estimated (J).
The %R for total kjeldahl nitrogen, nitrate, ammonia, and chloride were below the
QC limit in the MS associated with all samples. They were qualified as estimated
(J/UJ) in all samples.

No other issues were identified with the sample results and all results are deemed valid
and usable for environmental assessment purposes as qualified above. Data Validation checklists
completed for the June 2022 Sampling Event are provided in Appendix D.
4.2 Groundwater Results
The laboratory results for this Semi-annual 2022 groundwater monitoring event are
summarized on Table A-1 through Table A-3 and presented in Appendix A. These results are
compared to the New York State Department of Environmental Conservation Ambient Water
Quality Standards and Guidance Values for Class GA groundwater (herein referred to as the
Class GA groundwater standards and guidance values). Table A-1 provides the VOC results,
Table A-2 the inorganic parameters (metals) results, and Table A-3 the leachate indicator
results. Graphs illustrating historical total volatile organic compounds (TVOC's), select inorganic
parameters and select leachate indicators for the monitoring wells are presented in Appendix E.
Field parameters measured during the groundwater purging process are presented on the
groundwater sampling logs in Appendix B. A discussion of the field parameters and each
analytical parameter group is provided below.
4.2.1 Field Parameters
A review of the field parameters collected immediately prior to collection of the
groundwater samples, provided on the groundwater sampling logs in Appendix B, indicates the
following key findings:
Conductivity values were highest in deep wells located downgradient of the Site,
including wells MW-3D, MW-4D, MW-5D, and MW-8D. The higher conductivity
values appear to be Site-related. There is no Class GA standard or guidance value for
conductivity.
Groundwater temperatures were approximately 1 to 2 degrees Celsius higher in many
of the downgradient wells, relative to the upgradient wells. The highest temperatures
were recorded in well clusters MW-3, MW-4 and MW-8. There is no Class GA
standard or guidance value for temperature.

Nine out of the ten downgradient monitoring wells did not exhibit any VOC
concentrations above their respective Class GA groundwater standards.
Downgradient well (MW-4D) exhibited VOC concentrations of 1,2-dichloroethane
and 1,2-dichloropropane, which exceeded their respective Class GA groundwater
standards.
In general, the VOC results for this Semi-annual 2022 groundwater monitoring event are
consistent with previous sampling events. Based on these results, the Site is not a significant
source of VOC contaminants in groundwater.
4.2.3 Inorganic Parameters (Metals)
Review of the inorganic parameter (metals) results provided on Table A-2 in
Appendix A indicates the following key findings:
Iron, magnesium, manganese, and sodium were detected above their respective Class
GA groundwater standards/guidance values in one or more wells, as follows:
- Iron was detected above the Class GA guidance value of 300 ug/l in downgradient
wells (MW-3S, MW-3D, MW-4D, MW-8S and MW-8D). Iron concentrations in
these wells ranged from 302 ug/l in deep well MW-4D to a maximum of 57,500
ug/l in shallow well MW-3S.
- Magnesium was detected above the Class GA guidance value of 35,000 ug/l in
deep downgradient well MW-4D, at a concentration of 50,200 ug/l. At each well
cluster, higher magnesium concentrations were detected in the deep well.
- Manganese was detected above the Class GA groundwater standard of 300 ug/l in
all downgradient wells, with the exception of MW-5S. Manganese concentrations
in the wells which exceeded the groundwater standard, ranged from 526 ug/l in
deep well MW-6D to a maximum of 5,340 ug/l in deep well MW-3S.
- Sodium was detected above the Class GA groundwater standard of 20,000 ug/l in
five (5) downgradient wells (MW-3S, MW-3D, MW-4D, MW-5D and MW-8D).
Sodium concentrations which exceeded the groundwater standard in the
downgradient wells ranged from 36,300 ug/l in shallow well MW-3S to a
maximum of 152,000 ug/l in deep well MW-4D. At each downgradient well
cluster, higher sodium concentrations were detected in the deep well, which
suggests that the detected sodium concentrations may be partly associated with
naturally saline groundwater conditions at depth.

In general, the inorganic parameter results for this Semi-annual 2022 groundwater
monitoring event are consistent with previous sampling events and are indicative of limited
leachate impacts, typical of a closed MSW landfill. Groundwater in the North Fork of Long
Island is also naturally saline at depth, which may contribute to the higher concentrations of
some inorganic parameters observed in the deep wells.
4.2.4 Leachate Indicators
Review of the leachate indicator results provided on Table A-3 in Appendix A indicates
the following key findings:
Ammonia, color, nitrate and total dissolved solids were detected above their
respective Class GA groundwater standards in one or more wells, as follows:
- Ammonia was detected above the Class GA groundwater standard of 2 mg/l in 6
downgradient monitoring wells (MW-3S, MW-3D, MW-4D, MW-5D, MW-8S
and MW-8D). Ammonia concentrations in these wells ranged from 4.5 mg/l in
shallow well MW-3S to a maximum of 37.2 mg/l in deep well MW-5D.
- Color was detected above the Class GA groundwater standard of 15 APHA in
downgradient wells (MW-3S, MW-3D, MW-4D, MW-5D, MW-6S, MW-8S and
MW-8D). Color ranged from 20 APHA in well MW-4D to a maximum of 600
APHA in well MW-8S.
- Nitrate was detected above the Class GA groundwater standard of 10 mg/l in
downgradient well MW-4S, at a concentration of 13 mg/l.
- Total dissolved solids were detected above the Class GA groundwater standard of
500 mg/l in downgradient deep wells MW-4D and MW-5D, at concentrations of
1,200 mg/l and 519 mg/l, respectively.
In general, the leachate indicator results for this Semi-annual 2022 groundwater
monitoring event are consistent with previous sampling events and are indicative of limited
leachate impacts, typical of a closed MSW landfill.

5.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the results of this Semi-annual 2022 groundwater monitoring event, D&B
concludes the following:
Water level elevations, horizontal and vertical hydraulic gradients, and groundwater
flow directions are consistent with previous results and local/regional hydrogeologic
conditions.
In general, groundwater quality is consistent with previous sample results and are
indicative of limited downgradient leachate impacts.
A portion of the elevated metal concentrations detected in downgradient deep wells
may be related, in part, to naturally saline groundwater conditions at depth.
The results discussed in this report are generally consistent with previous sampling events
and do not indicate any significant changes or deterioration in groundwater quality that would
warrant a change in the scope of the monitoring program. Therefore, it is recommended that
Semi-annual groundwater monitoring continue consistent with the NYSDEC approved petition.
The next monitoring round (Second Semi-annual 2022 groundwater monitoring event) is
scheduled to be conducted in November of 2022 for Part 363 Baseline Parameters.
