2020 Biological Monitoring Data Summary

Dewey Loeffel Landfill Superfund Site

RI/FS Order for Drainageways (Index No. CERCLA 02-2013-2030)

Nassau, New York

Dear Mr. Mooney:

This letter report summarizes the fish tissue polychlorinated biphenyl (PCB) data

collected in 2020 by Arcadis US, Inc. (Arcadis) on behalf of the General Electric

Company (GE) at the Dewey Loeffel Landfill Superfund Site located in Nassau,

New York (Site). Fish tissue samples were collected from the western surface

water drainageway (the Western Drainageway) leading from the former Dewey

Loeffel Landfill (the Landfill), including the Valatie Kill and Nassau Lake. Due to

the ongoing removal action in the Northwest Drainage Ditch, Former Mead Road

Pond drainage channel, and Tributary T11A, fish samples were not collected in

those areas in 2020.1

The activities described herein were completed in general accordance with the

Phase 1 Remedial Investigation (RI) Work Plan originally submitted to the United

States Environmental Protection Agency (USEPA) on January 22, 2014, and last

revised on June 1, 2015, with revisions to the fish collection plan on July 21,

2016 and July 3, 2017.

This letter report also provides an analysis of trends in fish tissue PCB

concentrations. The fish tissue PCB data are presented in a series of tables and

figures, including box and whisker plots of wet-weight and lipid-normalized PCB

1 Although the Nassau Town Board voted in October 2018 to change the name of Tributary T11A to Little Thunder Brook, for consistency throughout site-related documents, the drainageway is referred to as Tributary T11A herein.

fish species by sampling station.

The compact disk accompanying this letter report includes the following appendices;

• Appendix A contains an updated trend evaluation of fish tissue PCB data;

• Appendix B contains box and whisker plots of wet-weight and lipid-normalized PCB concentrations for

individual species by sampling station and collection year;

• Appendix C contains copies of field notes and chain-of-custody (COC) forms for the 2020 fish

sampling; and

• Appendix D contains copies of laboratory analytical data reports for the 2020 fish tissue samples.

SUMMARY OF HISTORICAL FISH MONITORING PROGRAM

Fish tissue sampling has been conducted at the Site since the late 1970s. From 2002 through 2008, fish

sampling was conducted by NYSDEC in general accordance with the Long-Term Monitoring of PCB in

Biota of the Valatie Kill Drainage System (NYSDEC, 2002). NYSDEC led the fish sampling during this

time period, with manpower and equipment assistance by Arcadis (formerly Blasland, Bouck and Lee,

Inc.) on behalf of GE, which also funded the fish tissue laboratory analyses.

In 2008, at NYSDEC’s request, GE developed a Statement of Work (SOW) for the fish monitoring

program associated with the Western Drainageway leading from the Landfill. The SOW was originally

submitted to NYSDEC on December 22, 2008 and described a fish monitoring program for the Site to be

implemented during 2009 and 2010. NYSDEC provided comments on February 17, 2009, and GE

provided a revised SOW and responded to NYSDEC’s comments in a March 20, 2009 letter. On April 23,

2009, NYSDEC approved the revised SOW for implementation of the fish monitoring program in 2009

and 2010. GE subsequently agreed to also implement the revised SOW in 2011 and 2012. In 2013, GE

implemented the revised SOW to conduct the fish monitoring program and expanded upon the target

sample sizes for several species.

The 2014 fish monitoring was conducted in general accordance with a draft Phase 1 RI Work Plan, which

had been submitted to USEPA on January 22, 2014. Although the Phase 1 RI Work Plan had not yet

been approved, GE and USEPA agreed to proceed with the fish monitoring in 2014 as described in the

Phase 1 RI Work Plan. Similarly, the fish monitoring in 2015 was conducted in accordance with the Phase

1 RI Work Plan, last revised on June 1, 2015, which was approved by USEPA on August 6, 2015. On

June 29, 2016, GE submitted to USEPA a letter and supporting information describing the proposed fish

collection plan for 2016. Based on USEPA’s July 21, 2016 response letter, several changes from the

Phase 1 RI Work Plan were approved and implemented for 2016. On May 30, 2017, GE submitted to

USEPA a letter and supporting information describing the proposed fish collection plan for 2017. Based

on USEPA’s July 3, 2017 response letter, similar changes implemented in 2016 were also approved, and

implemented for 2017 sampling. The changes to the sampling program included the following:

• Stations 1, 2, 3, 4, and 5: fish collection was based on number of individuals observed to avoid

overfishing when limited numbers were present. If two or fewer individuals were observed per target

species over the sample area, these fish were released. If three or more individuals were observed

per target species over the sample area, these fish were retained for analysis;

• Stations 6 and 7: common shiner were removed from the monitoring program;

• Stations 7 and 10: forage-size brook trout were removed from the monitoring program; however, the

numbers of forage-size brook trout individuals observed in the field were recorded; and

• Station 11: white perch were removed from the monitoring program.

In 2018, 2019 and 2020, the monitoring program did not include fish sampling from the Northwest

Drainage Ditch, Former Mead Road Pond drainage channel, and Tributary T11A stations, based on

supplemental sediment and soil investigations and remediation being performed under the Tributary T11A

Removal Action under Paragraph 47.f Administrative Settlement Agreement and Order on Consent for a

Removal Action (Index No. CERCLA 02-2012-2005). Therefore, trend evaluations presented in this

annual report do not include Stations 1 through 5.

Fish monitoring in 2020 targeted collection of up to 120 forage-size fish composite samples and up to 135

edible-size fish samples (as summarized in Table 1 of this report). The monitoring included six sampling

stations (identified as S6 through S12) in the Valatie Kill (including both upstream of the Tributary T11A

confluence and downstream of the Nassau Lake Dam) and Nassau Lake (see Figure 1).

SUMMARY OF 2020 FISH SAMPLING ACTIVITIES

The 2020 fish sampling activities consisted of the following:

• On June 15, 2020, Arcadis, along with Chelsea Krieg of WSP (formerly Louis Berger, representing

USEPA), performed fish tissue sampling within the Valatie Kill above Kroner Road and Area 28

(sampling station S8), at Area 28 (sampling station S9), and downstream of Area 28 (sampling station

S10). A total of 51 forage-size fish composite samples and 25 edible-size fish samples from these

three stations were collected, field processed, and retained for analysis. Insufficient numbers of fish

were collected to achieve the target number of blacknose dace samples (n=7) at sampling stations S8

and S10. Creek chub were not observed at sampling station S10 and sample target size (n=5) was

not achieved at sampling station S9. One hundred forage-sized brook trout were observed at

sampling station S10.

• On June 16, 2020, Arcadis, along with Chelsea Krieg of WSP, collected fish within the Valatie Kill

within the background location near China Hill Road (sampling station S6), downstream of Tributary

T11 confluence (sampling station S7), and downstream of Nassau Lake (sampling station S12). A

total of 54 forage-size fish composite samples and 26 edible-size fish samples from these three

stations were collected, field processed, and retained for analysis. At sampling station S12, edible

target sample sizes were not met for bullhead and white sucker and no edible-sized rock bass were

collected. Twelve forage-sized brook trout were observed at sampling station S7.

• On June 16, 2020, Arcadis collected fish within Nassau Lake (sampling station S11). A total of 66

edible-size fish were collected, field processed, and retained for analysis; all target species were

included. Targets of opportunity for Nassau Lake are white perch and American eel. White perch

were not observed, and one American eel was collected.

For the 2020 biota monitoring program, a total of 105 forage-size fish composite samples and 117 edible-

size fish samples were submitted for laboratory analysis. These samples consisted of target number of

samples for each species from each sampling station, as defined in Table 1, with the exception of those

species not observed or where target sample sizes were not met as described above. Prior to shipment,

samples were packed in coolers with ice, along with appropriate sample COC forms, and sent to Pace

Analytical, Inc. (Pace) in Green Bay, Wisconsin for analysis of PCBs and percent lipids. The laboratory

processed each sample according to the sample-specific tissue preparation method detailed on the COC

forms (included in Appendix C). For edible-size fish samples, the laboratory followed the NYSDEC

standard operating procedures for filleting, which are consistent with historical procedures utilized for the

Site. The samples were analyzed by Pace for total PCBs using USEPA Method SW-846 8082 and lipids

content using standard gravimetric analysis. One forage-size fish composite sample (20-09-048) was

submitted to Pace but was not analyzed due to laboratory error.

RESULTS

The 2020 fish tissue PCB and lipid data are provided in Table 2. PCB Aroclors were quantified by the

laboratory and results are provided in Appendix D. PCBs were detected in each of the fish tissue samples

and were quantified as Aroclor 1260. Table 2 also includes the lipid-normalized PCB values, calculated

as the wet-weight PCB concentration (in milligrams per kilogram [mg/kg], equivalent to parts per million

[ppm]) divided by the decimal fraction lipids (yielding units of ppm-lipid).

Annual average fish tissue PCB concentrations (both wet-weight and lipid-normalized) are presented in

Tables 3A to 3D, and species that were collected in 2020 are bolded. Additionally, box and whisker plots

were developed for each species by location and collection year to visualize data trends are presented in

Appendix B. Summary statistics by plot and collection year for these are provided in Attachment 1 of

Appendix B.

EVALUATION OF TEMPORAL TRENDS

Appendix A evaluates temporal trends in fish tissue PCB concentrations within the Western Drainageway,

based on over 4,800 fish tissue samples collected from 1979 through 2020. The temporal analysis

concludes the following:

• Fish tissue PCB concentrations at the Valatie Kill background (sampling station S6) at China Hill

Road (located about 1.1 miles upstream of the confluence of Tributary T11A with the Valatie Kill)

typically range from 0.0125 to 0.05 ppm (Attachment 2, Figures BKGRD-1 and -2). These

concentrations may reflect potential for fish migration from downstream areas (there are no barriers to

the upstream migration of certain fish species to the background location).

• The species/locations with complete target sample sizes throughout the monitoring period (Table 1)

are most useful for evaluating temporal trends. Data for both individual species and combined

species (grouped into either forage-size or edible-size samples) indicate that fish tissue PCB

concentrations in the Valatie Kill between Tributary T11A and Nassau Lake for all fish species

(stations S7, S8, S9, and S10) have generally declined since remediation activities were conducted in

the former Mead Road Pond area and Tributary T11A between 2001 and 2003, and in Area 28 of the

Valatie Kill (located about 0.8 miles upstream from Nassau Lake) in late 2003. Tables 3B and 3C

provide the annual summary of PCB concentrations to allow comparison of pre-remedial to post-

remedial annual arithmetic means by target species per location for both forage-size and edible fish

target species from stations S7 through S10. In all comparisons by species and location, declines are

observed. Forage-fish average (combined data for blacknose dace, creek chub, longnose dace,

white sucker) PCB concentrations in 2020 are among the lowest on record for sampling stations S7,

S8, S9, and S10 (as shown in Attachment 3, Figures VK-2, VK-4, VK-6, and VK-8). Similarly, edible

brook trout and white sucker average PCB concentrations in 2020 are among the lowest on record for

sampling stations S7, S8, S9, and S10 (as shown in Attachment 3, Figures VK-3, VK-5, and VK-7).

• PCB concentrations in 2020 are among the lowest on record for several species/location

combinations within the Valatie Kill. For example, edible size white sucker from above Area 28 [S8]

and edible size brook trout and white sucker from below Area 28 [S10] (as shown in Table 3C annual

average comparisons), blacknose dace from Valatie Kill Below Confluence with Tributary T11A [S7],

creek chub from below Area 28 [S10], longnose dace from above Area 28 [S8] and from Area 28 [S9],

and white sucker from stations S7 to S10 (as shown in Table 3B).

• Fish tissue PCB concentrations in edible fish (combined data for American eel, bluegill, bullhead,

largemouth bass, pumpkinseed, yellow perch) from Nassau Lake (station S11, located about 3 miles

downstream from the Landfill) have declined over time. PCB concentrations in 2020 are similar to

those observed in 2010 through 2019 and at far lower levels than during the prior three decades

(1980-1989; 1990-1999; 2000-2009) (as shown in Attachment 4, Figure 1). Mean fish tissue PCB

concentrations are continually decreasing for the periods from 1980 to 1989, 1990 to 1999, 2000 to

2009, and 2010 to 2019. During the last four years (2017 to 2020), mean PCB concentrations were

among the lowest on record for bullhead (brown and yellow), largemouth bass, and yellow perch (as

shown in Table 3D). Downward trends in fish tissue PCB concentrations are less dramatic over time

as concentrations approach background levels. This is evident by observations from 2016 to 2020

which indicate that while average PCBs are around 1 ppm or lower for most species, concentrations

in certain species such as bullhead and largemouth bass recently have had slower rates of decline

and may have begun to plateau.

• Overall, fish tissue PCB concentrations have decreased over time, and generally reflect the

effectiveness of remedial activities performed for the Site. In some instances, PCB concentrations are

declining at a slower rate for certain species and stations. An example of this slower rate of decline is

whole-body fish (combined data for blacknose dace, creek chub, longnose dace, white sucker) at

station S10, where average PCB concentrations have consistently ranged from 1.6 to 1.8 ppm over the

last six years.

SUMMARY

This letter report summarizes the fish tissue sampling activities and PCB data that were collected in 2020

by Arcadis at the Site. Detailed evaluation of the 2020 PCB data (and the historical data) indicate that fish

tissue PCB levels have decreased substantially compared to earlier data.

TARGET SPECIES AND SAMPLE SIZES PER SAMPLE STATION FOR 2020

DEWEY LOEFFEL LANDFILL SUPERFUND SITE

NASSAU, NEW YORK

4. The numbers presented in this table represent both the target and the maximum number of samples per species. The minimum number of samples (either composites or individuals) will be a target of three samples for each specified species at each location for the Valatie Kill

and T11A. If target species abundance is low at location and three samples are not attainable, target species samples will be collected as available. For Nassau Lake, the target/maximum number of samples also represents the target/minimum number of samples for most

species. The exception is American eel since they are occasionally not available, are considered a target of opportunity, and will only be collected in Nassau lake as they appear while sampling for the other five species.

6. A reasonable level of effort will be expended to collect the target number of samples and will be determined in the field but generally is assumed to include two complete passes through the sampling reach. Additionally, field work (including boat launching and docking) at

Nassau Lake is generally expected to take up to one 8-hour day.

3. Fillet samples collected under this fish monitoring program have not historically included ribs and will not include ribs going forward.

Forage-Size Fish

Edible-Size Fish

1. Forage-size fish will be analyzed as whole-body composite samples, with up to 12 individuals per sample.

2. Edible-size fish will be analyzed as individual fish. Sample processing includes skin-on scales-off fillets for most fish such as brook trout, white sucker, bluegill, pumpkinseed, rock bass, yellow perch, and largemouth bass. American eel and bullhead (yellow or brown) will be

processed as skin-off fillets. Smaller edible-size fish that are too small to fillet may be analyzed as whole body minus head and viscera to meet laboratory tissue mass requirements.

5. Fish species listed with target sample sizes of NS (not sampled) indicate species that were removed from the 2016 Fish Sampling Plan. Conditional approval of these changes was made in response to Arcadis submittal for proposed 2016 Fish Sampling Plan (June 29, 2016)

by USEPA in their comment response letter dated July 21, 2016,

Technical Memorandum

Temporal Trends in Fish Tissue Samples

Dewey Loeffel Landfill

Dl_2020 Fish Sampling Report Appendix A

Technical Memorandum Temporal Trends in Fish Tissue Samples for the Western Drainageway from the Dewey Loeffel Landfill Superfund Site

1. Background

This Technical Memorandum summarizes the fish tissue polychlorinated biphenyl (PCB) data from the Western Drainageway of the former Dewey Loeffel Landfill Superfund Site (Site). This Technical Memorandum is similar to the previous Technical Memorandum included as Appendix A to the 2019 Fish Sampling Report but is updated to include the 2020 fish tissue data. This Technical Memorandum focuses on fish tissue data from the Valatie Kill and Nassau Lake and does not include data for Tributary T11A because fish tissue sampling was not conducted in Tributary T11A in 2018, 2019, and 2020. Please refer to the Technical Memorandum included as Appendix A to the 2017 Fish Sampling Report for information on fish tissue data from Tributary T11A.

Since 1979, over 4,800 fish tissue samples have been collected from the Western Drainageway, including over 3,600 samples since the completion of remedial actions in 2004. The fish tissue samples include “whole-body” samples and “edible-portion” samples (which are typically from larger fish). Samples have been collected from 12 sampling stations: five stations between the former Dewey Loeffel Landfill (the Landfill) and the confluence of Tributary T11A with the Valatie Kill; six stations within the Valatie Kill (between its confluence with Tributary T14 near China Hill Road and a location below the Nassau Lake dam and above County Route 7); and Nassau Lake. These stations are designated S1 through S12 (Attachment 1). Valatie Kill station S6 (north of its confluence with Tributary T11A) has been used to represent background conditions by the New York State Department of Environmental Control since fish monitoring started in 1979 and was included in their 2002 Long-Term Monitoring of PCB in Biota of the Valatie Kill Drainage Systemplan to represent a background condition.

Numerous figures have been developed that illustrate the trends in fish tissue data collected through 2020. These figures, which are included as attachments to this Technical Memorandum, present fish tissue PCB concentrations in two ways: as total “wet-weight” PCBs, and as “lipid-normalized” PCBs that adjusts the detected total PCB concentration based on the amount of lipid (fat) measured in the sample.

Total PCBs are calculated as the sum of detected Aroclors. Fish tissue PCBs have historically been characterized as Aroclor 1260, with infrequent identification of other Aroclors. From 2005 to 2020 only 80 out of 3,691 fish tissue samples (2.2%) have detections besides Aroclor 1260 (14 samples [0.40%] detected Aroclor 1248 and 66 samples [1.9%] detected Aroclor 1254). Most recently PCBs in two yellow perch from Nassau Lake collected in 2018 included Aroclor 1248. The percent contribution of Aroclor 1248 towards the total PCB concentration has ranged from 0 to 8%, with an average of 1.2%. The percent contribution of Aroclor 1254 toward the total PCB concentration has ranged from 0 to 33%, with an average of 11%.

The Technical Memorandum figures show PCB concentrations over time, using both individual species and all combined species for each station. Grouping of the data allows additional interpretation of potential temporal trends for individual locations or species. The figures display fish tissue PCB concentrations in a series of data plots. The box and whisker plots show individual sample results, outliers (mild and extreme), and various percentiles (90th, 75th, 50th, 25th and 10th). Summary statistics for the plots for this appendix are detailed by plot for each collection year within Attachment 5.

2. Assessment of Temporal Trends in PCB Concentrations in Fish Tissue Samples Collected in the Valatie Kill and Nassau Lake

This section describes the temporal trends in fish tissue PCB concentrations for two general areas: 1) the Valatie Kill between Tributary T11A and Nassau Lake (stations S7 through S10) (Attachment 3); and 2) Nassau Lake (station S11) (Attachment 4). Data from background station S6 on the Valatie Kill upstream from Tributary T11A are provided in Attachment 2.

Overall, fish tissue PCB concentrations have declined over time throughout the Valatie Kill drainage system, and post-remedial PCB concentrations are lower than pre-remedial PCB concentrations. Ongoing post-remediation declines in fish tissue PCB concentrations are also evident for many species and locations. Some species have shown a slower rate of decline in recent years and fish tissue PCB concentration in these species may be plateauing.

Fish tissue data reflect a gradient in PCB concentrations. PCB concentrations tend to be higher in Tributary T11A (about 0.2 to 0.5 miles downstream from the Landfill) compared to the Valatie Kill (beginning about 0.5 miles downstream from the Landfill) and Nassau Lake (about 3 miles downstream from the Landfill). In addition, PCBs have been detected in fish from the background location (station S6, located on the Valatie Kill about 1.1 miles upstream of the confluence of Tributary T11A with the Valatie Kill). These background concentrations may reflect potential for fish migration from downstream areas (there are no barriers to the upstream migration of some fish species to the background sampling location).

2.1 Valatie Kill between Tributary T11A and Nassau Lake (Stations S7, S8, S9 and S10) – see Figures in Attachments 2 and 3

Data from the Valatie Kill background station S6 at China Hill Road (1.1 miles upstream of the confluence of T11A with the Valatie Kill) show that fish tissue PCBs are above detection limits. These concentrations may reflect potential for some fish species to migrate from downstream areas. The presence of PCBs at concentrations well above detection limits (i.e., typically 0.0125 to 0.050 ppm from 2009 to present) in fish tissue samples at station S6, as reflected in edible-portion and whole-body samples, is illustrated in Figures BKGRD-1 and BKGRD-2 in Attachment 1. These data indicate a relatively consistent pattern, as 2020 PCB data are within the range of detected concentrations observed over the last six years (i.e., 2014 to current), with the overall mean for edible species of 0.25 ppm and whole body of 0.42 ppm.

Fish tissue PCB concentrations in the Valatie Kill between Tributary T11A and Nassau Lake (stations S7, S8, S9 and S10) have declined since remediation activities were conducted in the Western Drainageway upstream of the Valatie Kill (2001-2003) and in Area 28 of the Valatie Kill (2003-2004). The Valatie Kill is about 0.5 miles downstream from the Landfill while Area 28 is about 0.8 miles upstream from Nassau Lake. The overall decline in fish tissue PCB concentrations in the Valatie Kill immediately below the confluence of Tributary T11A (station S7) and the three stations located immediately above, at, and immediately below Area 28 (stationsS8, S9 and S10, respectively) is evident from both wet-weight and lipid-normalized PCB data for whole-body and edible-portion samples. For the last several years PCBs in individual species at some of these stations are among the lowest concentrations ever detected. The decline in fish tissue PCB concentrations in the Valatie Kill is illustrated in several of the figures included in Attachment 3, as discussed further below. Additional species-specific plots useful for further evaluating trends in Valatie Kill fish are provided in Appendix B. Summary statistics for these species-specific plots are detailed by plot for each collection year within Attachment 1 of Appendix B.

Edible-Portion Sample Data

o PCB data for edible-portion fish tissue samples for all species combined from stations S7, S8, S9 and S10 are presented in Figures VK-1, VK-3, VK-5 and VK-7, respectively. Although there is variability among years and stations (and between wet-weight and lipid-normalized data), these figures generally show an overall decrease in PCB concentrations over time. The decrease is most evident from the review of edible-portion fish tissue samples collected from 2011 to 2020 which indicate decreases in PCB concentrations from early post-remedial conditions (i.e., 2005 to 2006).

3


Whole-Body Sample Data

o PCB data for whole-body fish tissue samples for all species combined from stations S7, S8, S9 and S10 are presented in Figures VK-2, VK-4, VK-6 and VK-8, respectively. These plots also show an overall decrease in PCBs over time at most of these stations. The decrease is most evident from the review of the whole-body fish tissue samples collected from 2015 to 2020, which indicate decreases in PCB concentrations from early post-remedial conditions (i.e., 2005 to 2006).

Overall, both edible-portion and whole-body fish tissue PCB concentrations have decreased over time. These decreases generally reflect the effectiveness of remedial activities performed for the Site. In some instances, PCB concentrations are declining at a slower rate for certain species and stations. An example of this slower rate of decline is whole-body fish at station S10, where the average PCB concentrations have consistently ranged from 1.6 to 1.8 ppm over the last six years.

2.2 Nassau Lake (Station S11) – see Figures in Attachment 4

Fish tissue PCB concentrations in edible-size fish from Nassau Lake (station S11) have declined over time, and PCB concentrations in 2020 are similar to those observed in 2010-2019 and at far lower levels than during the prior three decades (1980-1989, 1990-1999, 2000-2009). The decline in fish tissue PCB concentrations in Nassau Lake is evident from both wet-weight and lipid-normalized data from edible-portion samples (which are the only types of fish tissue samples collected in Nassau Lake). The decrease is shown in the figures presented in Attachment 4, as discussed further below.

o All of the samples collected from Nassau Lake are edible-portion tissue samples from larger, edible-size fish. It is important to consider that the larger fish are several years old and PCB body burdens may not reflect current conditions. As such, trends in PCB concentrations in the larger edible-size fish may lag compared to small (younger) fish.

o Several species have been collected from Nassau Lake, including sunfish (bluegill and pumpkinseed), yellow perch, largemouth bass, bullhead (brown and yellow) and American eel. PCB concentrations vary significantly among these species, depending on factors such as trophic level, lipid content and size or age of the individual fish. Therefore, species-specific plots are useful for further evaluating trends in Nassau Lake fish (see Appendix B).

o PCB data for all combined species from Nassau Lake reveal considerable year-to-year variability, but show an overall decrease in PCBs over time (Figure NL-1). The overall decrease is particularly evident in the fact that the highest detected concentrations between 2016 and 2020 are much lower than many of the historic maximum detected concentrations, and often represent a decrease of 50% or more compared to historic maximum detected concentrations.

As noted previously, uncertainty exists in the background contribution to PCB levels; which may potentially reduce or slow thedecline of PCB concentrations in Nassau Lake fish. This is evident by observations from 2016 to 2020 which indicate that while average PCBs are around 1 ppm or lower for most species, certain species like bullhead and largemouth bass may have had slower rates of decline during this period and may have begun to reach a plateau.
