In our ongoing commitment to provide residents confidence in their drinking water, Wolverine Worldwide has made the decision to extend its filtration program to residents in the MDEQ-defined Rogue River, Wolven Northeast, and North Childsdale Study Areas. While sources are still being identified, we remain committed to the community and to doing what we believe to be the right thing for our friends, family and neighbors.
On January 10, 2018, the State of Michigan adopted a drinking water criterion of 70 ppt combined for PFOA and PFOS, which set an official standard for acceptable concentrations of these substances in groundwater used for drinking water purposes. This is the same conservative level adopted by the EPA in May 2016, which includes a significant safety buffer and assumes continued exposure over an entire 70-year lifetime.
As a result of the state’s new criterion of 70 ppt for PFOA/PFOS, Wolverine has changed its water filtration program in the study areas, including the Rogue River, Wolven Northeast, and North Childsdale Study Areas, as follows:
- Residents who have received confirmed results with a combined detection over 70 ppt for PFOA/PFOS are eligible to receive a whole house filter. Eligible residents will be contacted by Culligan to arrange for installation. These systems use dual canister granular activated carbon adsorption, and retesting from over 500 systems installed locally has demonstrated that they effectively remove PFOA, PFOS, and other PFAS, while at the same time ensuring that these substances are not returned to the environment. Post-installation sampling and filter replacement for whole house filters is being conducted at Wolverine’s expense while additional data is collected.
- Residents who have received confirmed results with a detection of PFOA or PFOS, but at a combined level that does not exceed 70 ppt, are eligible to receive a point-of-use filter for their kitchen sink. These systems are simple to operate, certified for the removal of PFOA/PFOS, and Wolverine has successfully installed over 100 of them in area homes. Filter replacement for point-of-use filters is being conducted at Wolverine’s expense while additional data is collected.
Even though the State has determined that 70 ppt of PFOA/PFOS is an acceptable level in drinking water, Wolverine is offering point-of-use filters to residents with lower concentrations because we are committed to providing residents confidence in their drinking water, and to doing what we believe to be the right thing for our friends, family and neighbors.
We started this blog to speak directly to the community and to help keep the facts straight, and we intend to do just that. Any residents with questions are encouraged to contact Wolverine directly at (616) 866-5627 or HouseStreet@wwwinc.com.
We Are Wolverine.
In our ongoing commitment to provide residents confidence in their drinking water, Wolverine Worldwide has made the decision to extend its whole house filtration program to residents in the MDEQ-defined Jewell and Wolven Study Areas that have confirmed test results with any detection of PFOA or PFOS. While the extent of any impacted area has not been determined, and sources are still being identified, we remain committed to the community and doing what we believe to be the right thing for our friends, family and neighbors.
Residents in the Jewell and Wolven areas who have received confirmed results with a detection of PFOA or PFOS, and who are eligible to receive whole house filters, will be contacted by Culligan to arrange for installation. Wolverine Worldwide is voluntarily paying for testing, bottled water service, single-tap filters and the whole house systems.
Earlier this fall, Wolverine selected the Culligan/Calgon filtration system, which relies on dual canister granular activated carbon adsorption. This system has been demonstrated to effectively remove PFAS, and ensures that these compounds are not returned to the environment. The Culligan/Calgon filtration system has been used to treat water for PFAS in over 1,000 homes around the country.
We will continue to keep the community updated about this issue through our blog at WeAreWolverine.com.
There have been questions regarding the operation and maintenance of water filtration system operation and maintenance. We wanted to share with the community a letter that is being sent to homeowners regarding this topic.
Wolverine Worldwide has offered to provide you with a whole house filtration system (“WHF”), which will be installed at your home by Kaat’s Culligan. Specifications of the WHF can be found on Wolverine’s blog, www.WeAreWolverine.com, and details about the operations and maintenance of the WHF are included in this letter.
- The WHF components include a pre-sediment filter, two carbon canisters, a post-sediment filter, a flow meter, and a UV lamp.
- The UV lamp unit requires a GFI electrical outlet. If your installation location does not have a GFI outlet, you will be contacted by Allied or Town and Country Electric to schedule the installation. The UV lamp does not need to plugged in to run the system.
- Following installation of the WHF, approximately 200 gallons of water will be flushed through the system to check piping connections, sampling ports, and flow meter performance. Following this system flush, you may begin using your WHF system.
- Post-Installation Sampling
After your WHF is installed and flushed, Rose & Westra/GZA will contact you to schedule initial sampling for PFAS. Following initial sampling, PFAS will be sampled on the following schedule:
Annually – for homes that are non-detect for PFOA/PFOS
Semi-annually – for homes that are from 1-70 ppt of PFOA/PFOS
Quarterly – for homes that are from 71-1000 of PFOA/PFOS
Monthly – for homes that are from 1000-7,499 of PFOA/PFOS
Weekly – for homes that are 7,500 or higher for PFOA/PFOS
Results will be continuously reviewed and used to revise the recommended sampling schedule, if needed.
After your WHF is installed, certain maintenance is needed for its continued operation on the following schedule:
Every 4 months – replace the pre- and post-sediment filters
Every 12 months – quartz sleeve and UV lamp replacement.
TBD – a schedule for carbon canister replacement will be determined based on the results of post-installation sampling
- Post-installation sampling and filter replacement will be conducted at Wolverine’s expense while additional data is collected.
Homeowners in the House Street Southeast Expansion Area whose water tests positive for PFOA or PFOS are eligible for a whole house filter
Wolverine Worldwide today announced it is expanding its whole house filtration program to include all homes in the House Street Southeast Expansion Area that have confirmed test results with any detection of PFOA or PFOS.
