1.0 QUALITY ASSURANCE/QUALITY CONTROL PLAN
1.1 Objective and Scope
The objective of this project is to provide post closure monitoring of the Southold
Landfill. The post closure monitoring program includes groundwater monitoring.
The purpose of this Quality Assurance/Quality Control (QA/QC) Plan is to develop and
describe the detailed sample collection and analytical procedures that will ensure high quality,
valid data for use during post closure monitoring.
6
P
1.2 Data Usage
4
J
The data generated from the field sampling program will be used to evaluate the
effectiveness of the landfill closure in accordance with Part 360. In addition, data will be used to
monitor health and safety of workers at the site and the health and safety of persons off-site.
1.3 Sampling Program Design and Rationale
The following presents a general discussion of the sampling to be conducted during
year 1 of post closure monitoring. ''
0 Groundwater: Four rounds of 12 groundwater samples will be collected. Each round
will consist of one sample from each of the six newly installed wells and the six
existing wells.
For a discussion of the sampling program and sample locations, see Section 4.0 of the
Manual.
a
♦1314W0314302.docMO2) 1-1
1.4 Analytical Parameters
The first round of samples will be analyzed for Baseline Parameters as defined in
6 NYCRR Part 360-2.11(c)(6) "Water Quality Analysis Table" (see Attachment A). The
subsequent rounds of sampling will be collected at three-month intervals and analyzed for
Routine Parameters as described in 6 NYCRR Part 360-2.11(c)(6) "Water Quality Analysis
Table" (see Attachment A). If turbidity of a groundwater sample is greater than 50 .NTUs, the
I
sample will be filtered for dissolved metals analyses. In such instances both filtered and
unfiltered samples will be analyzed for dissolved and total metals,respectively.
Table 1-1 presents a summary of the parameters/sample fractions to be analyzed together
with the sample location, type of sample, sample matrix, number of samples, frequency of
sample collection, type of sample container, method of sample preservation, holding time and
analytical method.
1.5 Data Quality Requirements and Assessment
Data quality requirements and assessments are provided in the 6/00 NYSDEC ASP,
which includes the detection limit for each parameter and sample matrix.Note that quantification
limits, estimated accuracy, accuracy protocol, estimate precision and precision protocol are
determined by the laboratory and will be in conformance with the requirements of the 6/00
NYSDEC ASP, where applicable. Table 1-2 presents a summary of the data quality
requirements.
i
In addition to meeting the requirements provided in the 6/00 NYSDEC ASP, the data
must also be useful in evaluating the nature and extent of contamination. Data obtained during
post closure monitoring will be compared to specific SCGs. The SCGs to be utilized include: .!
Matrix SCG.

The methods of analysis will be in accordance with the 6/00 NYSDEC ASP. Specific
analytical procedures and laboratory QA/QC descriptions are not included in this QA/QC plan, '
but will be*available upon request from the laboratory selected to perform the analyses. The
laboratory will be New York State Department of Health(NYSDOH) Environmental Laboratory
Approved Program (FLAP) certified for organic and inorganic analyses, and also USEPA CLP
certified.
1.5.1 Data Representativeness
Representative samples will be collected as follows:
• Groundwater (Monitoring Well)- Samples will be obtained after the monitoring well
has been purged of three to five well casing volumes and field measurements (pH,
conductivity, temperature and turbidity) have stabilized, or until the well is purged
dry (whichever occurs first)and allowed to recharge. Samples will be collected with a
dedicated polyethylene bailer.
• E ui ment Calibration'- Field equipment used for field measurements will be
calibrated daily before use according to the manufacturer's procedures.
• lr ui Ment Decontannation-Nonsterile sampling equipment will be deconuiminated
prior to use at each location according to the NYSDEC approved procedures
described on Section 1.8 of this QA/QC Plan.

1.5.3 Data Completeness
The acceptability of 100% of the data is desired as a goal for this project. The
acceptability of less than 100% complete data, meeting all laboratory QA/QC protocols/
standards,will be evaluated on a case-by-case basis.
1.6 Detailed Sampling Procedures
Groundwater samples will be collected from different locations as part of the post closure
monitoring for the Southold Landfill. Sample locations will consist of monitoring wells.
Sampling procedures and equipment are described in this section. A summary of the sampling
program, including sample media, locations, depths, equipment, rationale and analytical
parameters is provided in Table 1-3. Sample collection will be performed in conformance with
i
procedures described in Section 1.6.3.
The materials involved in groundwater sampling are critical to the collection of high
quality monitoring information, particularly where the analyses of volatile, pH sensitive or
reduced chemical constituents are of interest Sterile disposable polyethylene bailers will be
utilized for this project. j
i
.There will be several steps taken after the transfer of the water sample into the sample
container that are necessary to properly complete collection activities. Once the sample is
transferred into the appropriate container, the container will be capped and, if necessary, the
outside of the container will be wiped with a clean paper towel to remove excess sampling
material. The container will not be submerged in water in an effort to clean it Rather, if
necessary, a clean paper towel moistened with distilled/deionized water will be used.
The sample container will then be properly labeled. Information such as sample number,
location, collection time and sample description will be recorded in the field logbook. Associated
forms (e.g., Chain of Custody forms) will then be completed and will stay with the sample. The
samples will be packaged in a manner that will allow the appropriate storage temperature (4°C)

♦13144W0314302.dogRO ) 1-14
Prior to packaging any samples for shipment, the sample'containers will be checked for
proper identification and compared to the field logbook for accuracy. The samples will then be
wrapped with a cushioning material and placed in a cooler (or laboratory shuttle) with a
sufficient amount of bagged ice or "blue ice" packs in order to keep the samples at 4°C until
arrival at the laboratory.
All necessary documentation required to accompany the sample during shipment will be
placed in a sealed plastic bag and taped to the underside of the cooler lid. The cooler will then be
sealed with fiber(duct)tape, and custody seals will be placed in such a manner that any opening
of the cooler prior to arrival at the laboratory can be detected.
All samples will be shipped to ensure laboratory receipt within 48 hours of sample
collection in accordance with NYSDEC requirements. The laboratory will be notified prior to the
shipment of the samples.

2. Measure the depth of water using a decontaminated water level indicator and compute
the volume of sliding water in the well.
E
3. Remove three to five times the volume of standing water from the well until field
measurements (pH, conductivity, temperature, and turbidity) stabilize, or until the
well is dry, whichever occurs first, with a submersible pump. (Turbidity must be less
than 50 NTUs prior to collection of a sample for metals analysis. Greater than
50 NTUs may require filtering of the sample or waiting a maximum of 24 hours for
the turbidity to decrease.)
4. Remove the laboratory precleaned sample containers from sample cooler, label
container with an indelible marker, fill out Sample Information Record and Chain of
Custody Form(see Section 1.9).
ti
5. Obtain a sample by using the disposable polyethylene bailer. The order to which the
samples are collected is:VOCs,metals, cyanide,and wet chemistry parameters. ?'
4 1314\A0314302_doc(R02) 1-15
I
6. If the turbidity exceeds 50 NTUs,then the well should be sampled for all constituents
except metals. The well can rest for a maximum of 24 hours until a turbidity.reading
is less than 50 NTUs,once less than 50 NTUs,the metals sample can be collected.
7. If it is determined in consultation with the NYSDEC that filtering of the sample is
necessary (i.e., through direction from NYSDEC or after waiting a maximum of
24 hours), first.collect.an unfiltered sample in a sample container, replace the cover
on the sample container and label the sample. Next, pour an appropriate amount of
the remaining sample from the bailer into a second sample container through a filter
medium(0.45 microns) to remove particulates from suspension.Replace the cover on
the sample container and label the sample. The turbidity of both the filtered and
unfiltered sample will be recorded at the time of collection.
8. Gently pour the sample into the sample.container taking care not.to spill on outside of
bottle or overfill container and replace cover on the sample container. Samples for
volatile organic analyses, will have no air space in the sample vial prior to sealing.
This is done by filling the vial such that there is a meniscus on top. Carefully, slide
the septum, Teflon side down, onto the top of the vial and cap the vial. Check for
bubbles by turning the vial upside down and-tapping it lightly. If bubbles appear,
reopen the vial, remove the septum and add more sample (or resample). Replace the
septum,recap and check for bubbles. Continue until vial is bubble-free.
9. Return sample container to sample cooler.
10. Dispose of bailer.
11. Place disposable personal protective equipment into a 55-gallon drum.
1.7 Decontamination Procedures
All field sampling equipment should be sterile and dedicated to a particular sampling
I.
point. In instances where this is not possible, a field cleaning (decontamination) procedure will
be used in order to reduce the chances of cross contamination between sample locations. A
decontamination station will be established for all field activities. This will be an area located
away from the source of contamination so as not to adversely impact the decontamination z
Procedure,but close enough to the sampling area to keep equipment handlin to a minimum.
r
♦1314\AO314302.doc(R02) 1-16
1.7.1 Field Decontamination Procedures
All nondisposable'equipment will be decontaminated at appropriate intervals (e.g., prior
to initial use, prior to moving to a new sampling location and prior to leaving the site). Different
decontamination procedures are used for various types of equipment that perform the field
activities as discussed below. When using field decontamination, it is advisable to start sampling 4
in the area of the site with the lowest contaminant probability and proceed through to the areas of
highest suspected contamination.
1.7.2 Decontamination Procedure for D
nllin
I
All equipment such as drill rigs, backhoes and other mobile equipment should receive an
initial cleaning prior to use at the site. The equipment will then be decontaminated prior to
leaving the site and each time it.returns on-site. Unless otherwise specified and approved, all
wash/rinse solutions should be collected and contained on-site. The actual fate of this material
will be determined after review of analytical data generated from samples and on-site discharge
impacts have been evaluated.
After the initial washing, cleaning may be reduced to those areas that are in close
proximity to materials being sampled. Drill rig items such as auger flights, drill rods, and drill 1
i
bits are to be cleaned in between sample locations. C
I
All decontamination generated wastes will be contained in 55-gallon drums and stored in
the designated area.
Drilling equipment will be decontaminated in the following manner:
Scrub all surfaces thoroughly with nonresidual nonionic anionic detergent (such as
alconox) and tap water using a brush to remove particulate matter or surface film.
This is necessary in order to remove any solids buildup on the back of the rig, auger
i flights, drill rods, drilling head, etc. Any loose paint chips, paint flakes and rust must
also be removed.

• Steam clean(2121F).
1.7.3 Decontamination Procedure for Salapljqg E ui ment
Teflon, PVC, polyethylene, polystyrene and stainless steel sampling equipment
decontamination procedures will be the following:
i
• Wash thoroughly with nonresidual nonionic anionic detergent (such as alconox) and
clean potable tap water using a brush to remove particulate matter or surface film.
• Rinse thoroughly with tap water.
• Rinse thoroughly with distilled water.
• Rinse in a well ventilated area with methanol(pesticide grade)and air dry.
• Rinse thoroughly with distilled water and air dry.
• Wrap completely in clean aluminum foil with dull side against the equipment. For
small sampling items, such as scoops, decontamination will take place over a drum
specifically used for this purpose.
The first step, a-soap and water wash, is to remove all visible particulate matter and
residual oils and grease. This is followed by a tapwater rinse and a distiUcd/deionized water
1
rinse to remove the detergent. Next, a high purity solvent rinse is designated for trace organics
removal. Methanol has been chosen because it is not an analyte of concern in the TCL. The
solvent must be allowed to evaporate and then a final distilled/deionized water rinse is
performed. This rinse removes any residual-traces of the solvent. The aluminum wrap protects
the equipment and keeps it clean until it is used at another sampling location.

also be acceptable. This material should then be stored in such a manner so as to preserve it in
this condition. Special attention'to threaded joints may be necessary to remove cutting oil or
weld burn residues.
Materials and equipment that will be used within the monitoring well casing for the
purposes of well development and purging shall also be decontaminated.
t
The submersible pump will be decontaminated by the following procedures:
1. Place pump in a water solution of an nonionic anionic surfactant solution (such as
unscented Tide or Alconox) solution and wash the outside of the pump with a-scrub
brush.
2. Pump approximately five gallons of the wash solution through the pump.
3. Place pump in bucket of clean.water and pump out five gallons of water.
4. Wipe down the cable with deionized water and a paper towel.
5. Decontamination water will be disposed of on-site.

1.12 Control and Disposal of Contaminated Material
During -sampling of the monitoring wells, water will be generated from purging.
Specifically, all water associated-with the wells will be disposed of on-site. Decontamination w
water will also be disposed of on-site.
y
In general, soiled personal protective equipment (PPE) and disposable sampling
equipment (i.e., bailers,tongue'depressors, scoops)will be considered solid waste and contained
and disposed off-site. If hazardous waste contamination of PPE or disposable equipment is
suspected, due to elevated measurements of screening instruments, visual observations, odors or
other means, PPE and equipment will be drummed and secured on-site until a hazardous waste
determination can be made. Once a determination has been made, an approved disposal method
will be employed.

1.16 Corrective Action
r
A NYSDOH ELAP and CLP certified laboratory shall meet the requirements for
corrective action protocols, including sample "clean up"to attempt to eliminate/mitigate "matrix

The 6/00 NYSDEC ASP protocols include both mandatory and optional sample cleanup
and extraction methods. Florisil column cleanup is required for the pesticide/PCB fraction of
both soil and water samples. There are several optional cleanup and extraction methods noted in
the 6/00 NYSDEC ASP protocol. These include: Silica gel column cleanup, acid-base partition,
steam distillation and sulfuric acid cleanup for PCB analysis.
It should be noted, that if these optional cleanup and extraction methods are requested by
NYSDEC, holding time requirements should not be exceeded due to negligence of the
I
laboratory. However, subsequent to selection of the analytical laboratory for this project, a
meeting will be scheduled among representatives of the NYSDEC, the Town and the laboratory
to discuss these issues and establish procedures to ensure good and timely communications
among all parties.

1.17 Trip Blanks (Travel Blanks)
The primary purpose of this type of blank is to detect additional sources of contamination
that might potentially influence contaminant values reported in actual samples both
quantitatively and qualitatively. The following have been identified as potential sources of
contamination:
♦13141A0314302.doc(R02) 1-27
I
• Laboratory reagent water
• sample containers
• Cross contamination in shipment
• Ambient air or contact with analytical instrumentation during preparation and
analysis at the laboratory
• Laboratory reagents used in analytical procedures
A trip blank consists of a set of 40 ml sample vials filled at the laboratory with laboratory
dernonstrated analyte free water. Trip blanks should be handled, transported and analyzed in the
same manner as the samples acquired that day, except that the sample containers themselves are
not opened in the field. Rather, they just travel with the sample cooler. Trip blanks must
accompany samples "at a rate of one per shipment. The temperature of the trip blanks must be
maintained at 4°C while on-site and during shipment. Trip blanks must return to the laboratory
with the same set of bottles they accompanied in the field.
The purpose of a trip blank is to control sample bottle preparation and blank water quality
as well as sample handling. Thus,the trip blank travels to the site with the empty sample bottles
and back from the site with the collected samples in an effort to simulate sample handling
conditions. Contaminated trip blanks may indicate inadequate bottle cleaning or blank water of
questionable quality. Trip blanks are implemented only when collecting water samples, and
analyzed for volatile organic compounds only(i.e.,baseline sampling).

1.19 Matrix Spikes/Matrix Spike Duplicates and Spiked Blanks
Matrix spike (MS), matrix spike duplicates (MSD), and matrix spike blanks (MSB)
samples are quality control procedures, consistent with 6/00 NYSDEC ASP specifications, used
by the laboratory as part of its internal QA/QC program. The MS and MSD are aliquots of a
designated sample (water or soil), which are spiked with known quantities of specified
compounds. They are used to evaluate the matrix effect of the sample upon the analytical
methodology as well as to determine the precision of the analytical method used. A MSB is an
aliquot of analyte-free water,prepared in the laboratory, and spiked with the same solution used-
to spike the MS and MSD. The MSB is subjected to the same analytical procedure as the
MS/MSD and used to indicate the appropriateness of the spiking solution by calculating the

spike compound recoveries. The procedure and frequency regarding the MS, MSD and MSB are
defined in the 6/00 NYSDEC ASP. Site specific MS and MSDs should be collected at a
frequency of one per 20 samples or every 7 days (one for each sample delivery group), for each
sample matrix collected (Le.,water, soil, etc:). The laboratory is required to analyze an MSB at
o:
the same frequency as the MS/MSD.
1.20 Method Blanks
A method blank is an aliquot of laboratory water or soil, which is spiked with the same G
i
internal and surrogate compounds as the samples. Its purpose is to define and.determine the level
of laboratory background contamination. Frequency, procedure and maximum laboratory
containment concentration limits are specified in the 6/00 NYSDEC ASP as follows:
The laboratory shall prepare and analyze one laboratory reagent blank(method blank) for
each group of samples of a similar matrix (for water or soil samples), extracted by a similar
method (separatory funnel, continuous liquid extraction or sonication) and a similar
concentration level(for volatile and semivolatile soil samples only)for the following, whichever
is most frequent:
r
Each case of field samples received,or

i
0 Each 20 samples in a case, including matrix spikes and reanalyses,or
a Each 7 calendar day period during which field samples in a case were received (said
period beginning with the receipt of the first sample in that sample delivery group), or
o Whenever samples are extracted.
Volatile analysis requires one method blank for each 12-hour time period when volatile
target compounds are analyzed.

Currently, there are 16 monitoring wells at the Southold Landfill which are used to
on#or groundwater quality. These wells are grouped in pairs, with one well being shallow and
11ed across the water table, and the other well being screened deep just above the clay unit
,fit.underlies the landfill, with the exception of 5-68916, which is screened below the water
Viable at 103 feet, and 5-68831, which is screened below the clay unit at 190 feet. Depending on
hccatioll and ground surface elevation, the water table wells vary in depth from 27 to 77 feet
,elow ground surface (bgs) with the average depth being approximately 55 feet, and the deep
ells (exclusive of 5-68831) vary in depth from 85 feet to 150 feet bgs with the average depth
beiOg about 130 feet. The locations of these wells are shown on Drawing 2.
The existing monitoring wells are constructed with 2-inch diameter PVC casing and
stainless steel screens with locking steel protective surface casings. Screen lengths for the
'Shallow wells are 20 feet, and screen lengths for the deep wells are 10 feet. These wells,
exclusive of S-68831 and S-68916, are constructed in accordance with Part 360 requirements.
(5-68831 and S-68916 were constructed by the Suffolk County Department of Health Services in
the early 198Os and the construction details are not known.)
As part of closure construction, ten groundwater monitoring wells at five locations will
need to be abandoned since they are located in areas that will be graded and capped or where
C maintenance access roads are planned to be constructed. These wells are MW-2S and 213; MW-
3S and 3D; MW-6S and 6D; MW-7S and 713; and 5-68831 and S-68916. Well abandonment
will be in accordance-with Part 360 procedures contained in 360-2.11(a)(8)(vi). After the cap
I
and maintenance roads are constructed,six of the ten monitoring wells will be replaced with new
wells at approximately the same locations as the abandoned wells and constructed in accordance
with Part 360-2.11(a)(8).
Monitoring wells MW-2S and 2D will not be replaced since well clusters MW-4 and
MW-5 will effectively monitor groundwater quality downgradient of the MW-2 cluster, and
♦1314%G0820801.DOC(R02)
9-1
f
monitoring wells MW-7S and 7D will not be replaced since they are located upgradient of the
area of waste and historically have shown Iittle/background contamination. Locations of the
replacement wells are shown on Drawing 3.
Each new groundwater monitoring well will be constructed in a drilled borehole
approximately 8 inches in diameter. Drilling will be performed with hollow stem augers. The
wells will be constructed of a 2-inch diameter Schedule 304 stainless steel screen and threaded,
flush joint Schedule 40 PVC casing. Ten feet of stainless steel wire wrapped screen with 0.02-
inch openings will be installed in each deep borehole, and 20-foot screens will be installed. in
each shallow borehole, 5 feet above the water table and 15 feet below. The PVC riser will
extend from the top of the screen to 21/2,feet above ground surface and will be contained in a steel
protective casing with a locking cover.
The annulus of the borehole in the area of the screen will be sand-packed to a height of 2
feet above the screened interval with No. 1 Grade clean silica sand. A finer grained No. 00 sand
pack material (100 percent passing the No. 30 sieve and less than 2 percent passing the No. 200
sieve), 6 inches in thickness, will be placed on top of the sand pack between the sand and the
bentonite seal. A 3-foot seal of bentonite pellets or slurry will be placed immediately above the
k
filter material and 6 inches of No. 00 Grade silica sand pack will be placed above the bentonite
seal. The remaining annulus will be grouted to the surface with cement/bentonite grout. The
bentonite will be tested and/or warranteed to be free or organic and inorganic contaminants. All
material placed in the annulus of the borehole will be installed using a tremie pipe.
A 4-inch diameter protective outer steel surface casing with locking cover and a surface
cement pad will be installed around each well casing/riser. An illustration of well construction is
provided on Drawing 6.
