FISH CONTAMINANT MONITORING PROGRAM

2019 ANNUAL REPORT

A SUMMARY OF EDIBLE PORTION SAMPLING EFFORT AND ANALYTICAL RESULTS WITH RECOMMENDATIONS FOR UPDATES TO THE MICHIGAN DEPARTMENT OF HEALTH AND HUMAN SERVICES’ EAT SAFE FISH GUIDE

OCTOBER 2020

SECTION 1.0

INTRODUCTION

The Michigan Department of Environment, Great Lakes, and Energy-Water Resources Division (EGLE-WRD) has measured contaminants in over 20,000 fillet or other edible portion fish tissue samples collected since 1980. Fish contaminant analyses are limited to chemicals with high bioaccumulation potential in fish tissue. The presence of even extremely low concentrations of some bioaccumulative pollutants in surface water can result in fish tissue concentrations that pose a human or wildlife health risk. The EGLE-WRD conducts fish contaminant monitoring to address four goals:

1. The first goal is to support the development of the Michigan Department of Health and Human Services (MDHHS) Eat Safe Fish Guide. Edible portion sample results are used by the MDHHS to issue general and specific consumption advisories for sport-caught fish from Michigan’s surface waters. 2. The second goal is to support the regulation of commercial fisheries in the waters of the state. The Michigan Department of Agriculture and Rural Development (MDARD) uses edible portion monitoring results to regulate sales of the commercial catch. 3. The third goal of the fish contaminant monitoring is to identify spatial differences and temporal trends in the quality of Michigan’s surface waters. Temporal trends and spatial differences are examined by collecting whole fish, passive sampler, and caged fish samples in addition to the edible portion samples. 4. Finally, the fourth goal is to evaluate whether existing pollution prevention, regulatory, and remedial programs are effectively reducing chemical contamination in the aquatic environment. To achieve this goal, fish tissue samples are used to identify waters that are attaining or not attaining the designated uses described in Michigan’s Water Quality Standards (WQS), identify sources of pollutants, and track the effectiveness of remedial actions.

Prior to 1986, Michigan conducted fish contaminant studies on an as needed basis primarily to address specific problems. In 1986 a comprehensive plan was initiated to assess the degree of chemical contamination in fish from the surface waters of the state. EGLE uses three sampling elements to meet the goals of the monitoring program:

1. Edible portion sampling is often targeted toward sites of known or suspected contamination, sites popular with sport anglers, and sites with public access. Results from the analysis of edible portion samples are used to develop recommendations for updates to the MDHHS Eat Safe Fish Guide and to identify water bodies that are supporting and not supporting the fish consumption designated use described in the WQS. 2. Temporal trends in contaminant concentrations are assessed by analyzing whole fish samples collected every three to five years from 22 Great Lake, connecting channel, or inland water body locations. 3. Caged fish or passive water samplers are used to identify sources of bioaccumulative contaminants and to identify spatial trends in contaminant concentrations.

This report summarizes edible portion analytical results obtained since the last Fish Contaminant Monitoring Program (FCMP) annual report (Bohr, 2017), including all analytical results obtained by December 31, 2019.

Several state and federal agencies and tribal organizations assist with the EGLE-WRD fish contaminant monitoring efforts by collecting or analyzing samples and data. These include the

Michigan Department of Natural Resources-Fisheries Division (MDNR-FD), MDHHS, MDARD, United States Environmental Protection Agency (USEPA), United States Fish and Wildlife Service, Grand Traverse Band of Ottawa and Chippewa Indians, Chippewa Ottawa Resource Authority, Keweenaw Bay Indian Community, Little Traverse Bay Bands of Odawa Indians, and the Great Lakes Indian Fish and Wildlife Commission. In addition, sample collection plans and analytical results are reviewed by Michigan’s Fish and Wildlife Contaminant Advisory Committee (FAWCAC). The FAWCAC members include representatives from all Michigan agencies involved in fish and wildlife contaminant monitoring (EGLE-WRD, MDHHS, MDARD, and MDNR). The primary role of the FAWCAC is to coordinate fish and wildlife monitoring conducted by state agencies. Also, the FAWCAC reviews fish and wildlife consumption advisories proposed by state agencies in Michigan.

Michigan’s fish contaminant data have been compiled into a large database and are available by contacting the FCMP coordinator. Summaries of contaminant data are available in staff reports (MDNR, 1986a, 1986b, and 1989; Duling, 1988; Duling and Benzie, 1989 and 1990; Saalfeld et al., 1991; Waggoner, 1992; Wood, 1993 and 1994; Wood et. al., 1995; Day and Holden, 1996; Day, 1997, 1998, 1999, and 2002; Day and Walsh, 2000 and 2001; Day et al., 2004; Day and Bohr, 2005; Bohr and Zbytowski, 2006, 2007, 2008, Bohr and VanDusen, 2009, 2011a, 2011b, and Bohr, 2015, 2016, 2017). An inventory of samples analyzed in fiscal years (FY) 2017, 2018, and 2019 is presented in Appendix A. A summary of contaminant monitoring locations and species sampled between 1980 and 2019 with fish analyzed as edible portion samples listing contaminants causing consumption advice is provided in Appendices B and C.

SECTION 2.0

METHODS

2.1 FISH COLLECTION AND EDIBLE PORTION PROCESSING

The MDNR-FD and EGLE-WRD collected the majority of the fish using standard fish sampling techniques determined to be appropriate for individual water bodies. These techniques included electrofishing, trap nets, gill nets, and trawling. In addition, private consultants and tribal organizations have collected samples for the program.

The EGLE-WRD processed fish in accordance with the Surface Water Assessment Section Procedure WRD-SWAS-004 (available upon request). Total length and weight were recorded for each fish. Fish were prepared as standard edible portions (Table 1). Each sample was individually wrapped in aluminum foil, labeled, and held frozen until analyzed.

Over 20,000 edible portion samples have been analyzed by EGLE-WRD since regular fish contaminant monitoring began in 1980. This report summarizes the analyses of all the edible portion samples in the EGLE database, with detailed emphasis on the samples of 2,105 fish of 23 species from 178 locations analyzed in FYs 2017-2019. The edible portion sampling locations, species, and number of samples analyzed in that period are listed in Appendix A. Edible portion sampling was often targeted toward sites of known or suspected contamination, sites popular with sport anglers, and sites with public access. Analytical costs were covered by State of Michigan legislative appropriations, USEPA Great Lakes Restoration Initiative grants, Natural Resource Damage Assessment funds, and Consent Agreement assessments for specific projects.

2.2 CHEMICAL ANALYSES

Analysis of the FCMP fish tissue samples was conducted by the MDHHS-Analytical Chemistry Laboratory (ACL) (previously the Michigan Department of Community Health laboratory); historically, certain analyses were conducted by the MDNR, MDARD, USEPA, or one of several contract laboratories as needed. Current and past analytical laboratories all have quality assurance programs and use peer-reviewed methods of digestion, extraction, and quantitation. Table 2 lists the standard contaminants measured in most fish tissue samples. All results are reported to EGLE as wet weight concentrations.

Prior to 2000, polychlorinated biphenyls (PCB) were reported as total Aroclors; subsequent samples were analyzed using a congener detection method with results for a total of 83 congeners either individually or as co-eluting congeners (Table 3).

Analyses of chlorinated dibenzo-p-dioxin, dibenzofuran (Table 4a), and coplanar PCB congeners (Table 4b) were performed on a subset of edible portion samples. The analysis of coplanar PCB (dioxin-like) congeners in EGLE fish samples began in 2003 and has been part of the dioxin analysis in edible portion samples since 2007. Pace Analytical Laboratories analyzed the dioxin-like congeners under a subcontract with the MDHHS-ACL between 2006 and 2011; the MDHHS-ACL began analysis of those compounds in 2012.

Mercury was measured as total mercury by thermal decomposition, amalgamation, and atomic absorption spectrometry.

Selenium samples were analyzed in selected samples by the MDHHS-ACL using techniques based on the USEPA Method 200.11.

3

Perfluorinated compounds (PFC) in fish tissue were measured by the MDHHS-ACL by Reversed Phase High Performance Liquid Chromatography Multiple Reaction Monitoring Tandem Mass Spectrometry. A total of 16 PFCs can be quantitated in edible portion samples with the method used by the MDHHS-ACL (Table 5). Five of those compounds are not generally reported out since they have not been quantitated in fish tissue.

The standard MDHHS-ACL analytical method for toxaphene can identify a residue with chromatographic characteristics similar to toxaphene but does not specifically identify the residue as the pesticide toxaphene. Those results are referred to as “apparent toxaphene.” The MDHHS-ACL Limit of Quantitation (LOQ) for apparent toxaphene is 0.05 parts per million (ppm) (Table 2), which is higher than several of the MDHHS Fish Consumption Screening Values (FCSV). This means that we cannot identify fish populations with apparent toxaphene concentrations that would lead to a consumption recommendation of more than four meals per month. Recently the MDHHS-ACL has developed an analytical method (Parlar Method) that provides precise measurements of the concentrations of several toxaphene congeners (Parlars 26, 40, 41, 44, 50, and 62) as well as the toxaphene degradation products commonly referred to as Hx-Sed and Hp-Sed. Due to the higher cost of this analytical method it is used selectively on sample sets with relatively high apparent toxaphene concentrations. Toxaphene Parlars 26, 50, and 62 are the most likely of those compounds to accumulate in fish and represent about 90% of toxaphene measured in humans (MDHHS, 2009). Toxaphene results using the Parlar Method are reported here as the total of the three congeners and listed as Toxaphene Σ3PC26,50,62 (or Tox Σ3PC).

Finally, the MDHHS-ACL does not report contaminant concentrations below the quantitation level (QL), but above the detection level (DL) for mercury, selenium, or the organic parameters listed in Table 2. As a result, concentrations of these parameters that are below the QL are coded with a “K” in the FCMP database. In these cases, the “K” coded concentrations represent the MDHHS-ACL QLs. However, “K” codes assigned to dioxin, furan, and PCB congeners indicate that concentrations were below the DL while “J” or “NQ” codes indicate that concentrations were above the DL, but did not meet all of the quantitation requirements. The “J” code was used when analytical laboratory scientists decided the divergence from quantitation requirements was not significant; in these cases, the “J” coded concentrations are treated the same as uncoded results. The “NQ” coded concentrations are treated as null results.

2.3 SUMMARY STATISTICS

Total PCB concentration was estimated by summing the concentrations of the PCB congeners listed in Table 3. Individual congeners below the DL were assigned a concentration equal to zero for the purpose of calculating a total PCB concentration. Also, congener analyses that did not meet retention time criteria or were subject to analytical interference were assigned a concentration equal to zero for the purpose of calculating a total PCB concentration. If the results of an individual congener analysis did not meet all quantitation requirements (flagged “J”), then the congener was assigned a concentration equal to the estimated concentration for the purpose of calculating a total PCB concentration. If all of the congeners were below the DL, then the total PCB concentration was reported as less than the highest DL of the individual congeners (1 microgram per kilogram [part per billion (ppb)]).

Total chlordane concentration was estimated by summing the concentrations of five chlordane breakdown products: alpha-chlordane, gamma-chlordane, cis-nonachlor, trans-nonachlor, and oxychlordane. Individual compounds below the QL were assigned a concentration equal to zero for the purpose of calculating a total chlordane concentration. If all five compounds were below the QL, then the total chlordane concentration was reported as less than the QL of the individual compounds.

4

Total dichlorodiphenyl trichloroethane (DDT) concentrations were calculated by summing concentrations of the para, para’ and ortho, para’ forms of the following chemicals: DDT, dichlorodiphenyl dichloroethane (DDE), and 1,1-bis(4-chlorophenyl)-2,2-dichloroethane (DDD). Individual chemicals below the QL were assigned a concentration equal to zero for the purpose of calculating a total DDT concentration. If all six components were below the QL, then the total DDT concentration was reported as less than the lowest QL of the metabolites.

Total 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) toxic equivalents (TEQ) were calculated using the USEPA recommended toxic equivalency factors for seven dioxin, 10 dibenzofuran, and 12 dioxin-like PCB (dl-PCB) congeners (USEPA, 2010). The concentrations of individual dioxin, dibenzofuran, and dioxin-like PCB congeners in a fish sample were multiplied by toxic equivalency factors; the resulting products were summed to calculate a 2,3,7,8-TCDD TEQ concentration. Any individual congener concentrations less than the DL were assigned a value of zero for the purpose of calculating the dioxin TEQ. The MDHHS began including the 12 dioxin-like PCB congeners in the calculation of TEQ for the 2008 Fish Consumption Advisory; prior to that the TEQs were calculated using only the 17 dioxin and dibenzofuran congeners.

2.4 FISH CONSUMPTION SCREENING VALUES AND “EAT SAFE FISH” GUIDANCE DEVELOPMENT

The MDHHS is responsible for establishing, modifying, or removing sport fish consumption advisories in Michigan. The MDHHS toxicologists develop FCSVs based on a review of the best available scientific literature about the adverse health effects associated with a chemical of concern. The MDHHS has established FCSVs for mercury, total PCBs, dioxin TEQ, total DDT, one PFC (perfluorooctane sulfonate [PFOS]), selenium, and toxaphene for use in developing meal category guidance (Table 6). Supporting documentation for those FCSVs can be found online at Michigan.gov/MDHHS/0,5885,7-339-71548_54783_54784_54785-170340--,00.html.

Fish consumption guidance is developed based on an evaluation of the relationship between contaminant concentrations and screening values across all size ranges of a given species of fish taken from specific locations. Where possible, linear regression analyses of fish length versus contaminant concentrations are used to predict lengths at which the concentrations in fish species are likely to exceed screening values. When regression analysis indicates a positive slope with a correlation coefficient (R2) greater than 0.6, the MDHHS uses the regression line to estimate the contaminant concentration in fish between the minimum and maximum lengths represented in the dataset. The estimated concentration at a range of lengths is compared to the FCSV ranges.

However, contaminant concentrations and fish total length data often do not conform to the underlying assumptions of linear regression, or the line does not meet the minimum R2 required by the MDHHS. In these cases, the appropriate advisory is determined using the upper 95% confidence limit (95% UCL) on the mean concentration measured in a minimum of five fish of legal size. Fish will shrink a significant amount due to freezing; since FCMP fish are held frozen prior to being measured, those fish within ½-inch of the minimum legal size limit are considered to be legal size for the calculation of the 95% UCL.

The MDHHS prefers a dataset with a minimum of ten samples before establishing or modifying fish consumption advisories. However, best professional judgment is applied when evaluating smaller datasets. Additional details can be found in the Michigan Fish Consumption Advisory Program Guidance Document (MDHHS, 2016).

The MDHHS Eat Safe Fish Guide divides the state into five regions listing guidance for water bodies by county within those regions. The five regions include the Upper Peninsula (UP) and four quadrants in the Lower Peninsula (Figure 1). Each of the regions has a separate pamphlet style guide (available online at Michigan.gov/EatSafefFsh [Going Fishing? button]). Guidance for the Great Lakes and connecting channels that adjoin those five regions is included in the appropriate regional guides. The Web page noted above also has a Reports & Science button that provides links to the Fish Consumption Data and Recommendation sheets that were used to develop specific guidance.

SECTION 3.0

RESULTS AND DISCUSSION

This report summarizes the analytical results available by December 31, 2019, for edible portion fish samples collected primarily in 2016 through 2019. A total of 2,105 edible portion fish tissue samples collected during that time period are summarized in this report. This includes samples of 23 species from 178 locations in a total of 58 inland lakes, 18 impoundments, 21 rivers, and all of the Great Lakes and connecting channels bordering Michigan. Detailed summaries of the data used for “Eat Safe Fish” guidance are available online at Michigan.gov/EatSafeFish (Reports & Science button) or by contacting the MDHHS, Division of Environmental Health.

EGLE has conducted 1,628 edible portion fish sampling events at 679 sites in inland waters and 133 sites in Michigan waters of the Great Lakes and connecting channels between 1980 and 2019 (Tables 7 and 8). Over 20,400 edible portion samples have been analyzed to date; those results are also summarized.

3.1 General Highlights for Samples Collected and Analyzed in FYs 2017-2019

 Mercury was measurable in every sample analyzed in FYs 2017-2019 (Table 9). The highest concentrations were found in top predator species from inland lakes and impoundments.

 Several of the contaminants analyzed were either below the QL in all of the samples analyzed or measured no higher than the QL; these were aldrin, apparent toxaphene, lindane, heptachlor, heptachlorostyrene, hexachlorostyrene, nickel, pentachlorostyrene, and terphenyl (Table 9). Most of those contaminants have had concentrations near or below the QL in all samples since the start of fish contaminant monitoring in Michigan.

 Dieldrin, a breakdown product of aldrin, was quantified in fish tissue samples from 10 of 27 locations where chlorinated organic compounds were analyzed. Concentrations were very near the QL in most samples (Table 9). Overall, the annual percentage of samples with quantifiable dieldrin has decreased since the start of the FCMP. Beginning in FY 2018 the MDHHS-ACL no longer reports dieldrin results because of the extra cost involved in the analysis.

 Dioxin TEQ concentrations were measurable in every sample from the 16 locations where samples were analyzed for dioxin-like compounds in FYs 2017-2019 (Table 9).

3.2 General Highlights of All Comparisons with MDHHS Screening Values

The following statements are in reference to all edible portion samples analyzed between 1980 and 2019. The summarizations are based on a compilation of guidance for individual water bodies presented in Appendices B and C.

 Mercury levels in fish are elevated enough to cause some level of consumption advice in over 95% of the populations tested statewide and is a primary cause of advisories in over 72% of those populations.

 Mercury is a primary cause of fish consumption advisories for approximately 57% of the fish populations evaluated to date where both mercury and PCBs were analyzed.

7

 PCBs are a primary cause of fish consumption advisories for 43% of the fish populations evaluated to date where both mercury and PCBs were analyzed; PCBs would cause advisories for 67% of those fish populations if it was the only contaminant of concern.

 Mercury and PCBs cause equivalent consumption advisories in 9% of the fish populations evaluated to date.

 Total DDT is a primary contaminant in 1% of all fish populations sampled to date. All of those populations are in inland waters of the southern Lower Peninsula, and half are associated with the legacy contamination of the Pine River watershed in Gratiot County. In most cases where DDT is a primary cause, mercury, PCBs, or both cause advisories equivalent to the DDT advice. Total DDT would cause advisories in 24% of all fish populations tested if it was the only contaminant of concern.

 Toxaphene is a primary contaminant in three (0.5%) of the fish populations sampled to date, specifically in Glen Lake (Leelanau County) lake trout and Lake Superior siscowet and suckers. At least one other contaminant causes an equivalent advisory in the lake trout and siscowet. In addition, toxaphene would cause advisories for 4% of the fish populations sampled to date if it was the only contaminant of concern.

 Dioxin TEQ has been analyzed in 51 fish populations to date and is a primary cause of fish consumption advisories in 32 (63%) of those populations. Dioxin TEQ would cause advisories for 49 (96%) of the fish populations evaluated to date if it was the only contaminant of concern.

 PFCs were analyzed in 173 fish populations to date. PFOS is a primary cause of fish consumption advisories in 52 (30%) of those populations and would cause advisories in 102 (59%) of those populations if it was the only contaminant of concern.

 Selenium has been analyzed in 36 fish populations to date, primarily in water bodies near iron mining activity in Marquette County. Selenium is a primary cause of fish consumption advisories in two (6%) of those populations and would cause advisories in five (14%) of the populations if it was the only contaminant of concern.

3.3 Summary of Sampling and Screening Value Comparisons for Inland Waters Analyzed in FYs 2017-2019 by Region

This section discusses analytical results for mercury, total PCBs, total DDT, toxaphene (as either apparent toxaphene or Tox Σ3PC), dioxin TEQ, PFOS, and selenium assays conducted on samples collected primarily in 2016, 2017, and 2018 from inland lakes, impoundments, and rivers. These are the contaminants with screening values developed by the MDHHS. The discussion is organized into the five regions of the state used by the MDHHS in the Eat Safe Fish Guide (Figure 1).

Summaries for previously reported edible portion data are available online at www.Michigan.gov/EatSafeFish (Reports & Science button).

3.3.1 Upper Peninsula

A total of 18 fish populations comprised of nine species from 11 UP water bodies were sampled between 2016 and 2018 (Table 10). A summary of UP contaminant monitoring locations and species analyzed as edible portion samples between 1980 and 2019 is provided in Appendix B1.

Mercury was assayed in all of the UP samples analyzed for this report. Mercury exceeded MDHHS screening values in all 18 populations sampled and is the primary cause of consumption advisories in 17 of the 18 populations.

PCBs and the standard suite of halogenated organic contaminants were assayed in fish from Portage and Torch Lakes (Houghton County), Milwaukee Lake and Silver Lead Creek (Marquette County), and Massie Park Pond (Gogebic County). PCBs without the other halogenated contaminants were analyzed in samples from Big Creek (Marquette County). PCB concentrations exceeded the screening values in fish from Portage Lake, Torch Lake, and Silver Lead Creek.

Apparent toxaphene was assayed in 74 UP fish populations between 2016 and 2019; concentrations did not exceed the LOQ in 71 of those populations. Apparent toxaphene would cause advisories in three UP fish populations if it were the only contaminant of concern.

PFCs were assayed in samples from Big Creek and Silver Lead Creek due to their proximity to the former K.I. Sawyer Air Force Base. PFOS concentrations exceeded the screening values in fish from Silver Lead Creek.

Selenium was assayed in five UP fish populations including largemouth and smallmouth bass from Kingston Lake (Alger County), bluegill and largemouth bass from Milwaukee Lake (Marquette County), and largemouth bass from Shakey Lakes (Menominee County). Selenium concentrations did not exceed MDHHS screening values in those populations.

Dioxin TEQ was not assayed in the samples collected from the UP between 2016 and 2018.

3.3.2 Northwest Lower Peninsula (NWLP)

Six populations comprised of four species from five water bodies in the NWLP were sampled between 2016 and 2018 (Table 10). A summary of NWLP contaminant monitoring locations and species analyzed as edible portion samples between 1980 and 2019 is provided in Appendix B2.

Mercury was assayed in the six NWLP populations and concentrations exceeded MDHHS screening values in all six. Mercury is the primary cause of consumption advisories in all six populations.

PCBs and the standard suite of halogenated organic contaminants were assayed in fish from Portage and Manistee Lakes (Manistee County). PCBs without the other halogenated contaminants were analyzed in brown trout from the Hersey River (Osceola County). PCB concentrations exceeded MDHHS screening values in Manistee Lake black crappie and Portage Lake largemouth bass.

Apparent toxaphene was assayed in 55 NWLP fish populations between 2016 and 2019. Toxaphene is a primary contaminant causing consumption advisories in one population (Glen Lake [Leelanau County] lake trout) and a secondary contaminant in three other NWLP

fish populations. Apparent toxaphene concentrations did not exceed the LOQ in 51 of the NWLP datasets.

PFCs were analyzed in largemouth bass from Manistee Lake. PFOS concentrations did not exceed MDHHS screening values.

Dioxin TEQ and selenium were not assayed in the samples collected from the NWLP between 2016 and 2018.

3.3.3 Northeast Lower Peninsula (NELP)

Seventeen fish populations comprised of 11 species from eight water bodies in the NELP were sampled between 2016 and 2018 (Table 10). A summary of NELP contaminant monitoring locations and species analyzed as edible portion samples between 1980 and 2019 is provided in Appendix B3.

Mercury was assayed in all 17 NELP fish populations sampled and concentrations exceeded MDHHS screening values in all populations except for bluegill and pumpkinseed from Lake Margrethe (Crawford County).

PCBs and the standard suite of halogenated organic contaminants were assayed in six NELP fish populations including brown trout from the Au Sable River near Grayling (Crawford County), smallmouth bass from the Au Sable at Oscoda (Iosco County), northern pike from Mullett Lake (Cheboygan County), northern pike and walleye from Lake Winyah (Alpena County), and walleye from Van Etten Lake (Iosco County). PCB concentrations in the Au Sable River brown trout exceeded MDHHS screening values.

Apparent toxaphene was assayed in 33 NELP fish populations between 2016 and 2019; concentrations did not exceed the LOQ in any of those datasets.

PFCs were assayed in 14 of the NELP fish populations. PFOS concentrations exceeded MDHHS screening values in Au Sable River (at Oscoda) smallmouth bass, Lake Margrethe bluegill, pumpkinseed, and largemouth bass, and Van Etten Lake black crappie, largemouth bass, northern pike, smallmouth bass, and walleye.

Dioxin TEQ and selenium were not assayed in NELP fish populations between 2016 and 2018.

3.3.4 Southwest Lower Peninsula (SWLP)

A total of 83 fish populations comprised of 16 species from 42 SWLP water bodies were sampled between 2016 and 2019 (Table 10). A summary of SWLP contaminant monitoring locations and species analyzed as edible portion samples between 1980 and 2019 is provided in Appendix B4.

Mercury was assayed in all of the SWLP fish populations sampled between 2016 and 2019 and is a primary cause of consumption advice in 64% of those populations. Mercury would cause consumption advisories in 88% of the SWLP fish populations sampled if it was the only contaminant of concern.

Total PCBs were assayed in 39 of the SWLP fish populations sampled between 2016 and 2019. PCBs are a primary cause of consumption advice in 8 (20%) of the populations sampled and would cause a consumption advisory in 23 (59%) of the fish populations if it was the only contaminant of concern.

10

Total DDT was assayed in 38 of the SWLP fish populations sampled between 2016 and 2019 and was a primary cause of consumption advice only in bluegill, largemouth bass, and smallmouth bass from the St. Louis Impoundment of the Pine River (Gratiot County). DDT would also cause a consumption advisory in carp from the Grand River downstream of Webber Dam if it was the only contaminant of concern.

Apparent toxaphene was assayed in 38 SWLP fish populations between 2016 and 2019; concentrations exceeded MDHHS screening values in one population (Muskegon Lake largemouth bass). Concentrations were below the LOQ in all other datasets.

Dioxin TEQ was assayed in six SWLP fish populations sampled between 2016 and 2019 and is the primary cause of consumption advice for carp from the Kalamazoo River between the Marshall Dam and Morrow Dam (Calhoun and Kalamazoo Counties). Dioxin TEQ concentrations in rock bass and white sucker from the Chippewa River at Mt. Pleasant (Isabella County) did not exceed MDHHS screening values.

PFCs were assayed in 69 fish populations from 34 water bodies sampled between 2016 and 2019. PFOS is the primary contaminant causing consumption advice in 18 (26%) of those populations and would cause a consumption advisory in 34 (49%) of the fish populations if it was the only contaminant of concern.

Selenium was not assayed in samples collected from SWLP water bodies between 2016 and 2019.

3.3.5 Southeast Lower Peninsula (SELP)

A total of 55 fish populations comprised of ten species from 28 SELP water bodies were sampled between 2016 and 2019 (Table 10). A summary of SELP contaminant monitoring locations and species analyzed as edible portion samples between 1980 and 2019 is provided in Appendix B5.

Mercury was assayed in all of the SELP fish populations sampled between 2016 and 2019 and is a primary cause of consumption advice in 24 (44%) of those populations. Mercury would cause consumption advisories in 43 (78%) of the SELP fish populations sampled if it was the only contaminant of concern.

Total PCBs were assayed in 26 of the SELP fish populations sampled between 2016 and 2019. PCBs are a primary cause of consumption advice in four (15%) of the fish populations sampled and would cause advisories in 13 (50%) of the populations if it was the only contaminant of concern.

Total DDT was assayed in 26 of the SELP fish populations sampled between 2016 and 2019 and was not a primary cause of consumption advice in any of the sample sets. Total DDT would cause consumption advisories in one (4%) of the SELP fish populations sampled if it was the only contaminant of concern.

Apparent toxaphene was assayed in 26 SELP fish populations between 2016 and 2019; concentrations did not exceed the LOQ in any of those datasets.

PFCs were assayed in 53 SELP fish populations between 2016 and 2019. PFOS was a primary cause of consumption advisories in 24 (45%) of the populations sampled and would cause advisories in 36 (68%) of the populations sampled if it was the only contaminant of concern.

11

Dioxin TEQ and selenium were not assayed in SELP fish populations sampled between 2016 and 2019.

3.4 Summary of Sampling and Screening Value Comparisons for the Great Lakes and Connecting Channels Analyzed in FYs 2017-2019

This section discusses analytical results for mercury, total PCBs, total DDT, toxaphene (as either apparent toxaphene or Tox Σ3PC), dioxin TEQ, PFOS, and selenium assays conducted on samples collected in 2016, 2017, and 2018 from the Great Lakes and connecting channels and analyzed in FYs 2017-2019. These are the contaminants with screening values developed by the MDHHS.

3.4.1 Lake Superior

Edible portion samples of four populations comprised of four species from a total of five Lake Superior locations were collected in 2016 and 2018 (Table 11). Lake whitefish were collected from three areas in 2016 (off Grand Marais in eastern Lake Superior, off Marquette in central Lake Superior, and off 10-Mile Point west of the Keweenaw Peninsula), rainbow smelt were collected in 2016 from the Elm River (northeast of Ontonagon), and northern pike and walleye were collected in 2018 from Huron Bay (east of Keweenaw Bay). A summary of Lake Superior species analyzed as edible portion samples between 1980 and 2019 is provided in Appendix C.

Mercury was assayed in all samples and concentrations in all four populations exceeded MDHHS screening values. Mercury is the primary contaminant causing consumption advisories in Lake Superior northern pike, rainbow smelt, and northern pike, and is a secondary contaminant in lake whitefish.

Total PCB was assayed in all four Lake Superior populations and is a secondary cause of consumption advice for walleye and lake whitefish. PCB concentrations in the northern pike and rainbow smelt did not exceed MDHHS screening values.
