A Part 360 and Phase Il Hydrogeologic Investigation was conducted at the Southold
Landfill, Town of Southold, Long Island, New York in 1991 to obtain detailed hydrogeologic
information pertaining to the landfill site and to determine if the landfill is a source of groundwater
contamination. The results of this investigation are contained in a report, entitled "Part 360 and
Phase II Hydrogeologic Investigation Report, Southold Landfill, Town of Southold, Suffolk
County, New York," dated October 1991.
As a recommendation of this report, a long-term monitoring program was proposed as a
result of the data developed from the hydrogeologic investigation, and which satisfies the
requirements of the New York State Part 360 regulations for the operation and closure of the
existing landfill, and the permitting of a new landfill adjacent to the existing landfill. This report
presents the results of the most recent phase of the long-term monitoring program which was
conducted in January 1993, and a comparison to the July 1992 results, as well as any other
available sampling results.
During the period January26 through February 1, 1993, groundwater samples were
collected from 14 monitoring wells installed during the Part 360fPhase II Hydrogeologic
Investigation and two monitoring wells installed by the Suffolk County Department of Health
Services (SCDHS) at the landfill site. The locations of these 16 wells are shown in Figure 1-1.
In addition to the groundwater monitoring wells at the landfill, water samples were collected
from five private water supply wells which are located both upgradiem and downgradient from the
landfill (Figure 1-2). The groundwater and water supply samples were analyzed for the Part 360
Routine Parameters. The routine parameters list referenced throughout this report was modified to
include additional parameters based on the results of the July 1992 sampling evem.

2.0 FIELD INVESTIGATION
2.1 Monitoring Well Sa~,~pling
The depth to groundwater and total well depth was measured in all monitoring wells
comprising the long-term groundwater monitoring well network on January 26, 1993. The
measurements obtained from the wells were used to determine the groundwater level elevation and
calculate the volume of water to be purged from each well prior to sampling. Groundwater
elevations are presented in Table 2-1.
Four well volumes were purged from the monitoring wells in clusters MW-1 through
MW-7. A minimum of four field measurements for temperature, pH, specific conductance and
turbidity were obtained from the water purged from the wells. Stabilization was satisfied if three
consecutive measurements indicated that the water was representative of groundwater in the
aquifer. The measurements of the field parameters stabilized after removal of three well volumes
from wells S-68831 and S-68916.
The shallow wells in clusters MW-I through MW-7 were purged using disposable,
dedicated polyethylene bailers and polypropylene rope. The seven deep wells in the clusters, as
well as S-68831 and S-68916, were purged using a Grundfos Rediflo 2 submersible pump. As
described below, the pump was decontaminated before use on the site and between monitoring
wells to prevent introduction of contaminants from prior use and cross contamination between
monitoring wells. Samples collected from the monitoring wells were analyzed for the Part 360
Routine Parameters and additional parameters based on the results of the July 1992 sampling event.
Field measurements of turbidity from samples from the shallow wells in clusters MW-1
through MW-7 were greater than 50 NTUs immediately after purging. Samples for metals
analysis from these wells were collected approximately 24 hours after purging to allow water in
the well to clear.

2.2 Pump Decontamination Procedure
Decontamination of the Gmndfos Rediflo 2 pump consisted of an extemal wash with
Alconox and a brash followed by a rinse with clean water. Decontamination of the interior of the
pump consisted of pumping approximately 10 gallons of potable water through the pump. Water
for decontamination was obtained from a public water supply source at an outside hose connection
at the rear of the Town of Southold Recreation Center located in Peconic.
2.3 Private Water Supply Sampling
Samples from downgradient private water supply wells were collected from outside hose
connections at locations GW-6, GW-8 and WS-11 (Figure 1-2). The property at location GW-7 is
the subject of a bank foreclosure and was not accessible for sampling. Access to private well
GW-5 was denied by the owner at the time of sampling. Samples obtained from the water supply
wells were analyzed for Part 360 Routine Parameters.
Upgradient private supply wells WS-4, WS-6 and WS-7 were all scheduled for sampling as
part of this round, but the residence at WS-7 has since been destroyed by fire and could not be
sampled. Samples were obtained from WS-4 and WS-6 from outside hose connections and were
analyzed for Part 360 Routine Parameters.
2.4 Field Forms
Daily Field Activity Reports, Sample Infomaation Records, Water Supply Sample
Information Records, Daily Equipment Calibration Logs and Chain of Custody forms were
prepared during the sampling program and are contained in Appendix A.
2.5 D~t~ ValidationResult~
All sample data was validated to ensure that all analyses were performed in accordance with
the 1991 NYSDEC ASP. All results were IIX)percent contractually compliant. The results for
volatile organic compounds and select metals were qualified due to Quality Control (QC) criteria
falling outside control limits; however, all data is deemed usable. Data validation summaries and
data user advisory tables can be found in Appendix B along with completed data validation forms.

3.0 FINDINGS
3.1 Groundwater Flow Patterns
Groundwater contour maps were prepared from the groundwater elevations contained in
Table 2-1, and are presented in Figure 3-1 and 3-2.
3.1.1 Shallow Water Table
The water elevations measured in the shallow wells ranged from 0.78 feet to 1.04 feet higher
than water table elevations on July 22, 1992, but were approximately the same as those measured
in July of 1991. The water table contour map prepared from these measurements (Figure 3-1),
indicates a northwesterly flow of groundwater through the site reaffmning previous findings. The
groundwater gradient ranged from 1.8 x 10-4 feet of head loss per foot of horizontal distance in
the southem end of the site to 5.2 x 10-4 feet of head loss per foot of horizontal distance in the
northern end of the site. The hydraulic gradients are consistent with previous results.
3.1.2 Deep Groundwater
Water level elevations measured in the deep wells ranged from 1.03 to 0.75 higher than the
July 1992 round of measurements, but were consistent with those measured in the July 1991 round
of measurements. Well S-68831 was not included in the groundwater level measurement because
its screening interval places it far below those of the on-site deep wells. The piezometer contour
map prepared from the January 1993 level measurements (Figure 3-2) indicates a general
northwesterly flow direction and confirms all previous findings. The flow gradient ranges from
2.8 x 10.4 feet of head loss per foot of horizontal distance in the south end of the site to 4.1 x 10.4
feet of head loss per foot of horizontal distance in the south end of the site. The hydraulic
gradients are comparable to the previous findings.
The vertical hydraulic gradient at each well cluster location is shown in Table 3-1.

The vertical gradient was determined by calculating the difference in hydraulic head
between the shallow and deep wells, and dividing this figure by the distance between the water
table and the midpoint of each deep monitoring well screening interval. A slight downward
gradient of 3.4 x 10-4 ft/fI and 1.0 x 10-3 fi/ft exists at cluster MW-2 and MW-5, respectively. A
slight upward gradient of 1.0 x 10-3 ft/fI and 1.0 x 10.3 ft/ft exists at clusters MW-I and MW-4,
respectively. The vertical gradient at well clusters MW-3, MW-6 and MW-7 could not be
calculated since the difference in groundwater elevations between the shallow and deep wells at
these clusters was equal to or below 0.01 fi which is below the limit of accuracy for hand held
water level recording equipment.
The 1993 vertical gradients were consistent with those obtained during the 1992 round of
water levels indicating essentially horizontal flow conditions with little or no recharge. However,
relatively stronger downward vertical gradients of 1.4 x 10.2 ft/ft and 1.3 x 10-2 ft/ft were found
to exist at well clusters MW-2 and MW-7, respectively, in 1991. Slight downward gradients were
found throughout the site in the remaining wells in 1991, except for well clusters MW-3 and
MW-6, where a slight upward gradient was present. This indicates that, in general, the aquifer
was in a state of recharge during 1991.
3.2 Groundwamr Sa~Fling Results
3.2.1 Organic Sampling Result~
The volatile organic compounds (VOCs) detected in groundwater samples collected during
this round of monitoring are presented in Table 3-2. The analytical results for samples collected in
July 1991 and July 1992 ate also included for comparison purposes. For those wells not sampled
in July 1992 (PW004 GVS-11), PW005 (WS-4), and PW006 (WS-6), the most recent available
analytical results are included for comparison. Care should be taken when comparing the results
of these two sampling rounds since the most recent available data for WS-6 and WS-11 was
August of 1980.
VOCs detected in this round of on-site groundwater sampling include very low
concentrations of benzene, chlorobenzene, methylene chloride, 1,2 dichloroethane and vinyl
chloride. All of the above compounds have been detected previously in past groundwater
sampling events. Compounds detected previously, but not present in this round of

sampling, include chloroform, 1,2 dichloroethene, 1,2 dichloropropane, 1,2 dichlorobenzene, 1,4
dichlorobenzene and bromodichloromethane. Of the VOCs detected in on-site groundwater
samples collected as part of this investigation, only benzene, 1,2 dichloroethane and vinyl chloride
were found at levels only slightly exceeding New York State Class GA groundwater standards.
Figure 3-3 illustrates those organic compounds exceeding NYSDEC groundwater standards during
this round of sampling.
Methylene chloride, which was detected in on-site wells MW-4S (2.8 ug/1), MW-5S
(2.7ug/l) and S-68831 (1.5ug/1), was also present within two trip blanks at similar
concentrations. Since methylene chloride in a common laboratory contaminant it is not considered
as a groundwater contaminant.
Benzene, which was not detected in the July 1991 round of sampling, but was found in
monitoring well MW-5D in July 1992 (1.5 ug/1) and Januaxy 1993 (1.2 ug/l), was also found to be
present in upgradient monitoring well MW-ID at a concentration of 1.6 ug/1. The reason for the
detection of this compound, first in MW-5D and now in MW-ID, is unknown at this time and will
be evaluated further as more data becomes available as part of the long-term monitoring program.
Benzene was found to no longer be present in wells MW-2S and MW-3S where it was detected
during the July 1992 round of sampling. Vinyl chloride was also found at monitoring well
MW-5D at concentration of 4.6 ug/1, which exceeds the standard of 2 ug/l. However, the level of
vinyl chloride was lower than that detected in July of 1992 (17 ug/l). Since vinyl chloride was not
found to be present in any other well both on and off-site, its detection at MW-5D cannot be fully
explained at this time. However, the detection of this compound in 1992 and the decline in
concentration since the last time MW-5D was sampled may indicate a limited "slug" of
contaminated groundwater passing through the area of MW-5D. A possible source of this
contamination could be the commercial properties located upgradient of this well and immediately
adjacent to the landfill along Cox Lane. These properties include a commercial landscaping
company, a cement company, and a company that handles refrigeration units.
1,2-Dichloroethane was found in well MW-6D at a concentration of 16 ug/1 exceeding the
NYSDEC standard of 5 ug/l. Although not detected in the July 1992 round of sampling, 1,2
dichloroethane was present at an elevated concentration of 12ug/l in July of 1991. This
compound has also been found in low concentrations (below NYSDEC standards) in well MW-4D
and MW-5D. MW-6D is located downgradient of the former scavenger waste lagoons.
1,2-Dichloroethene was found previously at concentrations contravening the standard but was not
present in this most recent round of sampling.

Tetrachioroethane was the only VOC detected in private wells sampled as part of this
investigatinn. Tetrachluroethane was present in upgradient well PW006 (WS-6) at a low
concentration of 2.6 ug/1 which is below the NYSDEC standard of 5.0 ug/1 and was also detected
in 1992 (2 ug/1). Since this well is upgradient of the landfill and tetrachioroethene was not
detected in any other on-site or off-site well, the landfill is not the source of this contaminant.
Further smnpling of this well is part of the long-term monitoring program and will be further
evaluated as more data becomes available.
1,2-Dichioropropane had been detected previously in private wells PW004 (WS-II),
PW005 (WS-4) and PW006 (WS-6) at concentrations exceeding NYSDEC standards. These
samples were collected in August 1980 (PW004 and PW006) and September 12, 1989 (PW-005).
This indicates that at one time 1,2-dichloropropane, an insecticide, was more prevalent than it is
today and is no longer of concern.
3.2.2 Inorganic Sampling Results
The inorganic constituents detected in groundwater samples are listed in Table 3-3. Iron,
manganese, magnesium and sodium were the metals found to exceed New York State
standards/guidelines for Class GA groundwater in a number of samples collected during the 1991,
1992, and most recent rounds of sampling. Cyanide was previously found during the 1992
sampling program at a concentration of 110 ug/1 at monitoring well MW-2D which contravenes
the NYSDEC standard of 100 ug/1. It was suspected at that time that this detection of cyanide may
be due to matrix interference and would need to be confLrmed. Cyanide was not detected during
this round of sampling. Figure 3-4 illustrates those constituents exceeding NYSDEC groundwater
standards and includes leachate parameters discussed in Section 3.2.3 of this report.
In general, the levels of contamination with respect to groundwater standards have
decreased since the July 1992 round of sampling. No metals were found to exceed NYSDEC
groundwater standards or guidelines in both wells at well cluster MW-1 and at monitoring well
MW-5S. Concentrations have remained relatively the same at well clusters MW-2 and MW-6 and
at individual wells MW-3D, MW-5D and MW-7D. Iron concentrations in monitoring well
MW-3S have decreased from 2110 ug/1 to 498 ug/1. Manganese has decreased in well MW-4D
from 1540 ug/l to 425 ug/l although ixon levels have doubled to 61 ug/1. Both kon and manganese

have increased in monitoring well MW-7S when compared to the July 1992 round of sampling but
ate still far below those levels found during the July 1991 round of sampling. The smnpling
results for both wells S-68916 and S-68831 have remained the same except for an increase of [ton
concentrations in S-68916 from 6530 ug/l to 17,100 ug/l. Conversely, the concentration of iron
has decreased in S-68831 to a level below NYSDEC groundwater standards.
Sampling results for the private wells are also included in Table 3-3 and are compared to
results from December4, 1990, which were obtained by the United States Environmental
Protection Agency, and results from the July 1992 round of sampling. The metals found to
contravene standards during this sampling phase were iron, copper and sodium. Iron was found in
private well PW001 (GW-8) at a concentration of 1,150ug/l. Previous results indicated the
presence of this metal at 8,210 ug/l. Copper was found in private well PW002 (GW-6) at a
concentration of 241 ug/1 and was detected previously at a similar concentration of 268 ug/1.
Sodium and zinc were detected above NYSDEC standards in well PW003 (OW-5) during previous
rounds of sampling but were well below the standard during the 1992 round as well as this round.
Copper was found at concentrations of 758 ug/1 in downgradient private well PW004 (WS-11).
No other metals were found at elevated concentrations within these wells. Iron was found at an
elevated concentration of 743 ug/l in upgradient private supply well PW005 (WS-4) which is
consistent with previous findings. Sodium was also found at levels exceeding NYSDEC
groundwater standards at this well as well as adjacent upgradient well PW006 (WS-6). Again,
these results are consistent with previous findings. In both cases sodium was found at levels only
slightly above standards. These elevated metal levels may be atlxibutable to piping in the
residences and are not related to contaminants detected at the landiVfll.
3.2.3 Leachate Parameter Sampling Results
Leachate parameters found to contravene NYSDEC Class GA groundwater standards as part
of this sampling round include ammonia, chloride, nitrate and phenol. These constituents were
also found during the July 1991 as well as the July 1992 sampling events. In addition, hexavalent
chromium and boron found in isolated samples during the 1992 investigation were not detected
during this investigation. The sample results are presented in Table 3-4. Leachate parameters
exceeding NYSDEC groundwater standards were included in Figure 3-4.

Phenol, found to contravene NYSDEC standards in all wells sampled in July 1991 was
undetected in all on-site wells sampled as part of this sampling round, except for monitoring well
MW-3D and MW-IS where it was found at a concentration of 0.03 mg/1 and 0.02mg/1,
respectively. Phenol was found to contravene the NYSDEC standards in private well PW001
(GW-8) but the concentration of 0.01 mg/1 is below the New York State Department of Health
(NYSDOH) drinking water standard of 0.050 mg/l. This indicates a possible trend toward
decreash~g concentrations of phenol throughout the site.
Ammonia was found to exceed NYSDEC Class GA groundwater standards of 2 mg/l at
monitoring wells MW-2S, MW-2D, MW-3S, MW-3D, MW-4D, MW-6S and MW-6D. The
results are consistent with previous findings. Ammonia was undetected in downgradient wells
lVIW-4S, MW-SS and MW-SD, indicating an attenuation of the plume as it moves off-site.
Chloride, although not toxic, is a good leachate indicator since its presence corresponds closely
with areas of elevated metal concentrations, as well as elevated ammonia concentrations. Chloride
concentrations are generally unchanged since the last sampling round.
In July 1992, hexavalent chromium was found in well MW-7S at a level of 0.06 rog/1 and in
well S-68831 at a concentration of 0.09 mg/1, which slightly exceeded the NYSDEC standard of
0.05 mg/l. Hexavalent chromium was not analyzed in the 1991 round of sampling. Hexavalent
chrominln was detected in this round in wells MW-6S, MW-6D and PW001 (GW-8) although at
levels below NYSDEC standards.
Boron, which was found at elevated levels during previous sampling rounds, was not
detected at levels exceeding NYSDEC standards during this round. Nitrate was detected during
this round of sampling at levels exceeding NYSDEC groundwater standards in on-site well
MW-7D and private well PW004 (WS-11) at concentrations of 13mg/1 and 14.7mg/l,
respectively. Nitrate was also found in a sample of decontamination water (DW-I) collected from
the recreation center at a concentration of 12.4 mg/l. The presence of nitrate in downgradient well
PW004 (WS-I1) is consistent with previous fmdings where it was found at a concentration of
10.5 mg/l in downgradient private supply well PW002 (GW-6).
Since nitrate was not found to be present at elevated levels in any wells located immediately
downgradient of the landfill, the presence of nitrate in the sample cannot be attributed to the
landfill, but most likely due to agricultural practices (fertilizer usage).

4.0 CONCLUSIONS
In general, the analytical results obtained for the second phase of the long-term groundwater
monitoring program conducted in January 1993 show lower levels of contamination compared
with those collected in July 1992 and one yea~ earlier in July 1991. The presence of vinyl
chloride, benzene and 1,2 dichloroethane at levels slightly exceeding the NYSDEC Class GA
groundwater standards at limited locations at the Southold landfill will be addressed further as part
of the long-term monitoring plan. Further rounds of groundwater sampling are necessary to
identify any possible long-term trends which cannot be established based on three sets of
analytical data. VOCs were not detected in any downgradient private water supply wells sampled
as part of this investigation, but tetrachloroethene was detected in trace levels in upgradiem private
well PW006 (WS-6) and is not attributable to the landfill and is likely due to residential use and
disposal in an on-site sanitary system.
The general distribution and concentration of metals throughout the site appear to be lower
as compared to the July 1992 and July 1991 sampling events. Cyanide, which was detected in
well MW-2D in July 1992, was not found to be present in any well sampled as part of this
sampling event. Metals detected above the NYSDEC Class GA groundwater standards in private
wells sampled as part of this investigation were the same as previous investigations and include
iron, copper and sodium. Copper was not found in elevated concentrations in the landfill
monitoring wells. Therefore, the elevated levels of metals in the private water supply well
samples are not attributable to the landfill. The source of copper in the private water supply
samples could be from the copper piping.
The leachate parameter sample results obtained as part of this investigation, were also
generally lower compared to those obtained during the July 1991 and July 1992 sampling rounds.
Concentrations of phenol continue to show a decrease in concentrations throughout the site.
However, phenol was detected in downgradient private well PW001 (GW-8) at a level of
0.01 mg/1. Phenol had not been detected previously in this or any other private supply well. Since
the levels of phenol have shown to be steadily decreasing throughout the site and was found in
elevated concentrations both up and downgradient of the landfill, the presence of this compound
cannot be readily attributed to the landfill.

Hexavalent chromium, which was not analyzed for in July 1991, was detected at levels
slightly exceeding the NYSDEC standard of 0.05 mg/1 in wells MW-7S (0.06 mg/1) and S-68831
(0.09 mg/1) during the July 1992 sampling event. These are considered isolated occurrences since
this round of sampling has shown them not to be present above NYSDEC standards. The only
routine parameter to exceed NYSDEC standards in the private wells was nitrate, which was found
in well PW004 (WS-I1) at a concentration of 14.7 mg/1. On-site nitrate levels were significantly
below NYSDEC standards, indicating no impact from the landfill. The likely source of this nitrate
contamination could be fertilizers or on-site sewage disposal. Nitrate was found previously in
private well PW002 (GW-6) at a concentration of 10.5 mg/1 but was below NYSDEC standards
during this round of sampling.
In summary, the groundwater quality at the Southold landfill appears to have hnproved
slightly during the January 1993 sampling event, and there continues to be no impact off-site on
private water supply wells downgradient from the landfill.

5.0 RECOMMENDATIONS
The results of the 1993 Groundwater Quality Assessment Report generally confirm the
fmdings of the Part 360/Phase II Hydrogeologic Report, as well as previous investigations. The
findings indicate that a weak plume is emanating from the landfill but is limited in that the plume
has not caused any observable impacts to nearby downgradient groundwater quality in off-site
private water supply wells. The 16 on-site monitoring wells, in addition to the downgradient and
newly incorporated upgradient private water supply wells, provide an adequate and comprehensive
monitor'mg network. Therefore, continued, long-term, semiannual sampling of the monitoring
network is recommended to fulfill the Part 360 landfill operation, closure and expansion
requirements.
The Part 360 requirements call for all environmental monitoring points not previously
sampled to be analyzed for two rounds of sampling. The first round of sampling as part of the
Part 360/Phase Ill Hydrogeologic Investigation was performed for Part 360 Baseline Parameters.
The sampling program, which is the subject of this report, comprises the first round of sampling as
part of the long-term monitoring plan (July 1992), which was performed for Baseline Parameters
and this, the second round of sampling which was performed for a modified list of Routine
Parmneters as recommended in the July 1992 Groundwater Assessment Report. The existing data
base for these three rounds of baseline sampling is considered sufficient so that the next round of
sampling will be performed for Baseline Parameters as described in Section5.0 of the
Part 360/Phase II July 1992 Groundwater Assessment Report. Since the 1992 round of sampling
showed elevated levels of contaminants not previously detected, it was recommended that the list
of selected routine parameters be modified to include those compounds not previously detected at
levels exceeding NYSDEC groundwater standards. Since hexavalent chromium was detected in
elevated concentrations during the July 1992 round of sampling and is not part of the original list
of Baseline Parameters, it is recommended that this constituent be added to the baseline list.
Based on the results of this round of sampling, no modifications to the routine list are deemed
necessary at this time, but may become necessary in the future as conditions change.
It was recommended in the July 1992 report that the sampling frequency of the long-term
monitoring parameters be semiannually, with one sampling event being for Baseline Parameters
and one for modified Routine Parameters on an alternating basis. Therefore the next round of
sampling will be in July 1993 and consist of the Baseline Parameters shown in Table 5-1. Table
5-1 also shows the recommended list of Routine Parameters proposed for the subsequent
semiannual round of sampling.
