1.0 BACKGROUND

The Dewey Loeffel Landfill Superfund Site is located in southern Rensselaer County, New

York, approximately four miles northeast of the village of Nassau. From 1952 until 1968, the

Site was used for the disposal of an estimated 46,000 tons of waste materials generated by

several Capital District companies including General Electric (GE), Bendix Corporation

(now Honeywell International, Inc. [Honeywell]) and Schenectady Chemicals (now SI Group,

Inc. [SI]). The waste included industrial solvents, waste oils, polychlorinated biphenyls

(PCBs), scrap materials, sludge and solids. Volatile organic compounds and other hazardous

substances have seeped out of the landfill and contaminated the groundwater. PCBs have

also moved downstream, causing contamination of sediment in and near Nassau Lake.

In 1968, the State of New York ordered the operator to stop discharges from the disposal

facility and perform cleanup work. From 1980 until the site was added to the federal

Superfund list in March 2011, numerous investigations and cleanup actions were performed

at the Site under the New York State Department of Environmental Conservation’s

(NYSDEC’s) Superfund program. These activities included, but were not limited to, the

installation of a clay cap and soil/bentonite clay slurry wall at the landfill, the removal of

drums and storage tanks, the installation and operation of a bedrock groundwater recovery

well system, monitoring and maintenance of residential well treatment systems, disposal off-

site of extracted contaminated groundwater and leachate and removal of contaminated

sediments.

In a letter dated January 13, 2009, the State of New York requested that EPA place the site on

the federal Superfund National Priorities List (NPL). In March 2011, the Dewey Loeffel

Landfill was added to the NPL. Shortly thereafter, the EPA began gathering landfill and

groundwater data as part of an Initial Supplemental Site Investigation (ISSI).

In October 2011, the EPA’s Removal Program took over the operation and maintenance of

the groundwater extraction and the leachate collection system. In April 2012 the EPA

reached an agreement to perform a removal action at the Site with two of the parties

responsible for the contamination, GE and SI. This agreement required that the companies

take over the collection and the removal of contaminated groundwater and leachate. As part

of the agreement, the companies would also construct a treatment plant adjacent to the

landfill to treat the contaminated groundwater and leachate. GE and SI took over “pump and

truck operations” and the operation and maintenance of the groundwater extraction and

leachate collection system in August 2012. The construction of the treatment plant was

completed in November 2013 with EPA oversight during startup of the plant.

On September 30, 2013, EPA and GE finalized an agreement which requires GE to perform a

Remedial Investigation/Feasibility Study (RI/FS) for the landfill and groundwater

components of the Site. On October 30, 2013, the EPA and GE finalized an agreement

which requires GE to perform the RI/FS for the drainage ways (surface waters and sediments)

4

component of the Site. Together the two agreements will result in a comprehensive RI/FS for

the Site.

During public availability sessions held in March 2014, EPA committed to collecting

samples near the site and in Kinderhook Lake. For this specific site activity, EPA Region 2

Emergency and Remedial Response Division (ERRD) requested that EPA Region 2 Division

of Environmental Science and Assessment, Hazardous Waste Support Branch-Superfund

Support Team (DESA/HWSB/SST) collect and analyze approximately ten water and nine

sediment samples. Samples were collected in May 2014 at locations above (north) and below

(south) of the water treatment plant on the Valatie Kill, on the Valatie Kill between Nassau

Lake and Kinderhook Lake, and in Kinderhook Lake.

2.0 SAMPLING PROCEDURES

The sampling procedures were in accordance with the guidelines set forth in the Uniform

Federal Policy (UFP) Quality Assurance Project Plan (QAPP) which is located in Appendix

B.

3.0 DESCRIPTION OF EVENTS

On May 19 and 20, 2014, two EPA Region 2 DESA/HWSB/SST members and the EPA

Remedial Project Manager collected a total of ten surface water and nine sediment samples from

the Valatie Kill and Kinderhook Lake in the vicinity of the Dewey Loeffel Landfill in Nassau,

Rensselaer County, NY. The total of ten (10) surface water and nine (9) sediment samples were

collected and submitted to the laboratory for analysis. One field duplicate sample was collected

for each matrix. The surface water samples were collected directly from the water body with the

sample bottle and the sediment samples were collected using a disposable scoop or a reusable

decontaminated sample coring device depending on the depth of the water.

The sample location identification “DLL” indicates the site name Dewey Loeffel Landfill, the

“SW” prefix indicates surface water and the “SED” prefix indicates a sediment sample. The

“BG” prefix on two samples indicates samples collected from background locations.

Analyses of all samples submitted for metals parameters were performed by EPA Contract

Laboratory Program (CLP) laboratory Chemtech by the analytical procedure listed below in

Table 1. All samples submitted for organic analyses were performed by EPA Contract

Laboratory Program (CLP) laboratory KAP Technologies by the analytical procedure listed

below in Table 1. Samples collected for the analysis of ammonia, Total Suspended Solids,

Total Dissolved Solids, 5 Day Biological Oxygen Demand (BOD), Chemical Oxygen

Demand (COD), oil and grease, and total phosphorus were analyzed by the EPA Region 2

DESA Lab in Edison, New Jersey by the SOPs listed in Table 1 below. The analyses of pH,

temperature, specific conductance, Dissolved Oxygen, and Oxygen Reduction Potential were

5

performed in the field at the time of sample collection also by SOPs provided in Table 1

below.

The EPA Region 2 DESA Lab samples were hand delivered for analysis on Wednesday May

21, 2014 and the samples analyzed by the CLP laboratories were delivered via UPS overnight

mail on May 21, 2014 under tracking numbers: 1Z 061 547 21 1000 549 2 (Chemtech) and

1Z 061 547 21 1000 546 5, 1Z 061 547 21 1000 547 4, 1Z 061 547 21 1000 545 6, 1Z 061

547 21 1000 550 9, and 1Z 061 547 1000 552 7 (KAP). The sample details, Chain of

Custody Records and shipment information can be found in the Trip Report located in

Appendix E.

The samples submitted for analysis were analyzed according to following methodologies:

4.0 RESULTS

Quality Assurance/Quality Control

Two pairs of blind field duplicate samples were collected for field quality control purposes:

one surface water pair (SW-02/SW-22) and one sediment pair (SED-06/SED-66). According

to EPA Quality Control criteria, aqueous duplicate pairs should have a relative percent

difference (RPD) of 30% or less and solid/sediment samples an RPD of 50% or less.

Duplicate precision was achieved for all parameters analyzed for both the aqueous and

sediment samples collected (i.e., RPD for aqueous duplicate pair was less than 30% and RPD

for sediment duplicate pair was less than 50%).

The organic data was validated by U.S. EPA DESA personnel according to U.S.

EPA/DESA/HWSS standard operating procedures (SOPs) HW-35 (Rev. 2) Semivolatile Data

Validation, HW-33 (Rev. 3) Low Medium Volatiles Data Validation, HW-36 (Rev. 4)

Pesticide Data Validation, and HW-37 (Rev. 3) Polychlorinated Biphenyl (PCB) Aroclor

Data Validation.

The inorganic data were validated according to SOP Numbers HW-2b (Rev. 15) ICP-MS

Data Validation and HW-2c (Rev.15) Mercury and Cyanide Validation. The water quality

parameters data are validated by the U.S. EPA Region 2 DESA Lab staff.

During the validation process, some of the results are estimated with a “J” qualifier for a

number of reasons explained in the Data Assessment Reports located in Appendix C.

Aqueous Samples

Ten (10) surface water samples (including one field duplicate sample) were collected from

select areas of the Valatie Kill and Kinderhook Lake. The aqueous samples were collected

from the same locations as the sediment samples (with the exception of SW-02 where no

sediment sample was collected) and analyzed for the same parameters listed in Table 1

above. The sample locations can be found on the site maps located in Appendix A of this

report.

The aqueous sample results reported for the inorganic metals parameters are at concentrations

commensurate with those same parameters detected in each aqueous background sample

collected. The sole organic parameter detected is Bis(2-ethylhexyl)phthalate, which is a

common laboratory contaminant inherent to plastic materials. All other compounds were

non-detect in the surface water. The compound 1,4-dioxane was not detected in surface water

samples.

Water quality parameters which were analyzed on-site are presented below:

Sediment Samples

Nine (9) sediment samples (including one field duplicate sample) were collected from select

areas of the Valatie Kill and Kinderhook Lake. The sediment samples were collected from

the same locations as the aqueous samples (with the exception of SW-02 where no sediment

sample was collected) and analyzed for the same parameters listed in Table 1 above.

Metals in Sediment Results

The metals in sediment results are presented as tables in Section 6 below. Similar to the

aqueous samples, results reported for the inorganic metals parameters in sediment samples

are commensurate with the concentrations reported in each background sample. Regarding

mercury analyses, no concentrations are detected above the laboratory’s Reporting Limit,

which initially was 0.2 ug/l and re-analyzed with a lower Reporting Limit of 0.05 ug/l. For

both sets of analyses, the laboratory’s detection limit is 0.0079 ug/l. Although the Holding

Time has been exceeded for the mercury re-analyses, any low concentrations present would

likely have been reported as estimated, below the reporting limit, since the laboratory’s

detection limit approaches an order of magnitude lower than the Reporting Limit of 0.05

ug/L.

Organics in Sediment Results

The organics in sediment results are presented as tables in Section 6 below. As stated above,

phthalate contamination is common and often results from the use of plastic materials. Low

level concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) were detected in sediment

samples SED-06 and SED-07, but were not detected in sediment samples upgradient of those

8

samples or near the Dewey site. The compound 1,4-dioxane was not detected in sediment

samples.

Low levels of pesticides were detected in a number of samples. Concentrations of Methoxychlor

reported in sediment samples are also detected in each background sample collected. Low

concentrations of DDE and DDD were detected in only 1 sample downgradient of the site, SED-

07. DDT was detected in SED-01 and SED-07, but not in the samples located between these two

locations. Lindane was found at a very low level in the background sediment sample, BGSED-01,

but not in the downgradient samples.

Three sediment samples located above Kinderhook Lake, SED-01,SED-03 and SED-04 report

low concentrations of the PCB Aroclor 1260. No PCBs were detected in samples collected within

Kinderhook Lake.

5.0 CONCLUSION:

Surface water and sediment samples were analyzed according to the methodologies presented

in Table 1 above. All sample results from the May 19-21, 2014 sampling event are presented

in Appendix C and summarized in the tables present in Section 6 below. Based on this data

and the information contained in this report, Kinderhook Lake does not appear to be impacted

by the contamination from the Dewey Loeffel Landfill site. However, as part of the RI/FS at

the Dewey Loeffel Landfill site some additional sediment samples will be collected below

Nassau Lake in the Valatie Kill. In addition, surface water samples will also be collected

from the Valatie Kill after direct discharge from the Dewey Loeffel Water treatment plant

begins. Past land use would indicate that pesticides were commonly used in the area and low-

level detections in sediments are not unexpected. PAH detections in two sediment samples

are also lower than typical background levels in the state and considered to likely be due to

recreational activities (marine structures, boating, etc.). PAH’s were not found in samples

taken from the Valatie Kill before it enters Kinderhook Lake.
