Tamara (Tammy) Bergstrom is a Rockford resident and currently serves on the Rockford City Council. She and her husband, Herb, have lived in the City of Rockford for more than 35 years and their children attended Rockford Public Schools and Our Lady of Consolation grade school. Tammy formerly worked as a reporter for a variety of newspapers, covering Rockford and other northern Kent County municipalities. She currently serves as the marketing manager for a large regional law firm.
My family has been part of Plainfield Township since 1870. We have been fighting ground water pollution since the 1960s. Our family farm (Braman Orchards) was located adjacent to the Bell Landfill (a longtime Superfund site) and was the target of eminent domain proceedings to expand the landfill. I have been fishing the Rogue River since the 1960s and have been an environmental activist since that time. I have witnessed, first hand, the destruction of the Rogue River and the long-term rehabilitation that has occurred. Our family history resides in Plainfield Township and the resolution of this problem is a requirement for the long-term health of the community.
I am a retired professor of Medical Laboratory Science and Associate Dean of Health Professions from Grand Valley State University. I and my husband have lived near downtown Rockford for 45 years, and we raised our four children here. Our family drank Rogue River water, which we now know was contaminated with PFAS, for over 20 years. Professionally, I was a member of the American Society for Clinical Laboratory Science’s Government Affairs Committee for six years, chairing the national committee for three years. As a member of that committee, I went to Capitol Hill in Washington, D.C. annually to speak to our elected official about federal legislation and regulation that impacted medical laboratories, our patients, and our laboratory professionals. Since 2016, I have served on the Spectrum Health Institutional Biosafety Committee, which provides local oversight for research involving recombinant and synthetic nucleic acid molecules. I believe my background in Medical Technology, which includes microbiology and hematology, my advanced education in Science Studies, and my professional experiences provide me with skills to contribute to the CAG mission.

John Hart is a graduate student at Grand Valley State University pursuing a M.S. in Biology with an Aquatic Sciences emphasis. He received his B.S. in Environmental Science with a specialization in Environmental Health from Oakland University in 2021. Through both degrees, his coursework has been water-oriented, specializing in identifying pollutants in aquatic systems as well as understanding both the fate and transport and the toxicological effects of these contaminants. His undergraduate coursework was also focused on public health and safety with courses in environmental health and environmental law. His research at Oakland University and Grand Valley State University are focused on identifying surface water contaminants and distilling the results into a product that can be given to interested stakeholders. These persistent organic pollutants at the Wolverine sites are an environmental and health hazard that has impacted all organisms in Rockford and the Rogue River watershed. He hopes to use his experience and background to help distill the opinions and results of governmental agencies and independent consulting firms to concerned citizens to help restore these contaminated sites.

I got involved with the CCRR by default due to the fact that I was driving my kids to school when I noticed demolition activities occurring at the Wolverine Worldwide former plant. Though I had my own concerns regarding the demolition of the WWW tannery in 2010-2011, it was not until I attended the EPA Community Meeting on April 24, 2012, that these concerns all became shockingly real. Comments being made by the city government and other civic leaders – that Rockford is a ‘special’ community and able to navigate its own contamination issues – did not match up to the grave reality of the facts. When the public discussion turned to lead, and it seemed that even lead exposures were being downplayed, I launched up from my seat and told it how it was. “Hey, I’m Tom Konecsni and I’ve just moved from California and there are no safe levels of lead.” Shortly after this meeting, I met up with some of the members of the CCRR to discuss my concerns and to volunteer my time and abilities. Over the next seven years, I was able to contribute to the work in a variety of ways. I helped with sample collecting, attended core group meetings, located tannery workers for interviews, met with a representative from Senator Gary Peters’ office, and helped track down other possible areas of contamination. I found the work to be interesting and compelling, especially having elementary school-age children attending Valley View Elementary School and also with my home’s location now being impacted by the West Wolven Street plume. My work experience in the private sector as an Environmental Health and Safety Manager/Leader offers a unique skill set and perspective to my participation in the Wolverine CAG, and I look forward to having a substantive role in the on-going challenges of caring for the health and safety vitality of my community.

I became a member of Concerned Citizens for Responsible Remediation (CCRR) in 2010 when I lived across the street from the former Wolverine World Wide (WWW) tannery. As I worked with the group, I became increasingly concerned about potential releases of contaminants to the air, to surface water, and to groundwater. Fueled by this concern, I joined with others to request an investigation of the Site, post-demolition, by means of Citizen Preliminary Assessment Petition. I am one of 25 citizens who signed this document. I also worked to address the contamination issues from another angle—by running for Rockford City Council and subsequently being elected to this position in November 2012. As a city council member, I worked to establish an environmental a conflict resolution group involving the city of Rockford, WWW, the DEQ and CCRR. The West Michigan Environmental Action Council (WMEAC) was supportive of efforts to develop such a group, or even a CAG, if that better served the purposes of all the stakeholders. In the end, for multiple reasons, a CAG was never formed. As a member of the council, I grew more interested in law, so when I completed my city council term in 2016, I enrolled in Cooley Law School where I will complete my studies in December 2019. My hopes for the Wolverine CAG are this: that we will engage in a healthy, honest, and productive dialogue with all of the stakeholders, and that we will take action to ensure the best possible outcomes for all of those affected by the contamination issues related to the former tannery Site and the House St. dumpsite. These actions need to protect for the present and for future generations to come. The stakes here are profound.

Tobyn has lived in Plainfield township her whole life, save 1 year that she was a 4th grade teacher in Kansas. She married her husband in 2014. She is a mother to 2 boys, one born in 2016 and the other in 2020. A majority of the time she worked as a teacher but now stays home with her children and 2 dogs. Tobyn loves staying at home in the house that was purchased in 2012 to start a life. However, her sanctuary was tarnished by the fact that 20 times the EPA limit of PFAS was found in the drinking well there in 2017. Since then, she has felt the need to take up a torch of advocacy work and spreading awareness of why and how PFAS is toxic. She has spoken to Representatives and Senators at both State and Federal levels. She has done a lot of work with the media and has attended conferences and panels regarding PFAS. She joined the CAG in February of 2022 to help her community and keep the work going to address this home-town as well as global issue.

Woverine Tannery PFAS Frequently Asked Questions

In short, a CAG (community advisory group) is a group of experts and local residents formed with the help of the EPA to facilitate communication between the EPA and communities affected by contamination and subsequent efforts. 

From the EPA: A Community Advisory Group (CAG) is made up of representatives of diverse community interests. A CAG is designed to serve as the focal point for the exchange of information among the local community and EPA, the State regulatory agency, and other pertinent Federal agencies involved in cleanup of the Superfund site. Its purpose is to provide a public forum for community members to present and discuss their needs and concerns related to the Superfund decision-making process. A CAG can assist EPA in making better decisions on how to clean up a site. It offers EPA a unique opportunity to hear-and seriously consider-community preferences for site cleanup and remediation. However, the existence of a CAG does not eliminate the need for the Agency to keep the community informed about plans and decisions throughout the Superfund process.

The Wolverine CAG serves in this role for the ongoing cleanup of contamination stemming from Wolverine World Wide’s operations in the Rockford and Plainfield areas.

Wolverine World Wide operated a tannery in downtown Rockford for decades. Operations at that site and waste dumping in the surrounding area contaminated soil and water with high levels of volatile organic compounds, semi-volatile organic compounds, metals, ammonia and cyanide. Surface water and groundwater (including residential wells) near the tannery and dump sites were contaminatedwith high levels of PFAS (up to 490,000 parts per trillion), according to Michigan’s Department of Environment, Great Lakes, and Energy (EGLE). 

Much of this contamination was uncovered by a group of citizens concerned over the tannery demolition in 2010-2011.

The House St. site is being equipped with an impermeable cap. Contamination around the Tannery site has been mapped and the shallow contaminated soil (contaminated soil at 3 or fewer feet from the surface) is being excavated and disposed of. Sections of the soil have been excavated down to a 16 foot depth due to lead and/or chromium contamination. These excavations are the final step in the EPA emergency response actions, which will be followed by a long term remediative process. The municipal water supply is run through granular activated carbon (GAC), filtering PFAS levels to trace amounts.

PFAS, poly-and perflouroalkyl substances, are a large group of manufactured chemicals used for their waterproofing, non-stick and firefighting abilities. From World War II to the present day, they’ve been manufactured and used in non-stick pans (e.g. Teflon), popular waterproof technology (e.g. Scotchgard, Gore-Tex) and firefighting foams used on military bases and airports, according to Grand Valley State University. In high concentrations, some PFAS have been connected to health problems for humans.

PFOA, PFOS, PFNA about 3,000 others are some of the specific chemicals that fit under the PFAS umbrellas.

PFAS are often called “forever chemicals” because they stay in the environment and bodies for years. Many PFAS will not break down in the environment or bodies, but collect in places in the body, causing problems. Because of this process, called bioaccumulation, PFAS concentrations are prone to increase in bodies over time, according to the US EPA.

PFAS have dispersed throughout the environment and are found in nearly every human in the United States. People can be exposed to PFAS through products treated with PFAS, food grown in contaminated soil or irrigated with contaminated water, contaminated drinking water and other sources.



According to a study of people exposed to PFOA in the Ohio River Valley, there is a probable link between PFOA exposure and high cholesterol, ulcerative colitis, thyroid disease, testicular cancer, kidney cancer and pregnancy induced hypertension. The EPA reports there are less clear links between certain PFAS and negative effects on birth weight and immune systems.



It could. Grand Valley State lists several substances that have important and measurable effects at similar levels. Read about it here.

If your water is contaminated with PFAS, there are in-home filters that can help. EGLE says a filter must meet NSF P473 standards. Read more from EGLE’s in-home filtration fact sheet under “Certified Filtration Systems.”




The Food and Drug Administration conducted a PFAS sampling study in 2019, which showed the the PFAS of most concern (PFOS and PFOA) were detected only in seafood, though other PFAS were identified in more foods. Seafood can have high levels of PFAS due to a process called bioaccumulation. Read more in Michigan’s PFAS Action Respsone Team’s (MPART) summary or in the FDA report itself.

Unfortunately the most viable remediation strategy is to excavate the contaminated soil and take it elsewhere for incineration, or take it elsewhere to stabilize the contaminants with minerals, resins, or other amendments. There are other technologies in development, but they face significant challenges preventing them from being used on a wide scale. Read more about these technologies in the Interstate Technology Regulatory Council fact sheet.
