Belmont - House Street and Other Disposal Areas

  • Belmont - House Street and Other Disposal Areas

    Map of maximum detected PFOS + PFOA concentrations in water wells within the investigation areas.

    This area consists of a former licensed disposal facility owned and operated by Wolverine near House Street and Herrington Avenue in Plainfield Township and several unregulated dump sites across three townships in northern Kent County.

    A concerned citizens group brought the former disposal location to the DEQ’s attention on 1/24/17 and the DEQ requested that Wolverine sample residential wells in response to the concerns.  Following a detection of PFAS  May 2017,  Wolverine began conducting an on-going water well sampling program in several investigation areas and has provided bottled water and whole house and point of use filters.   Wolverine is also conducting environmental investigations and waste removals at several potential dump sites as well as investigations to determine the extent of groundwater contamination. 

    The DEQ has provided oversight, conducted follow-up sampling, investigated dozens of disposal locations, and participated in two town hall and several neighborhood meetings. The DEQ has also developed a ground water criterion for the protection of drinking water for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS).  The residential and nonresidential drinking water criterion is 0.07 μg/L (70 parts per trillion) for the combined concentrations of PFOA and PFOS, which sets an official state standard for acceptable concentrations of these contaminants in ground water used for drinking water purposes. This combined criterion took effect on January 10, 2018.

    View the map of maximum detected  PFOS + PFOA concentrations in water wells within the investigation areas.  The map illustrates the maximum combined PFOS and PFOA concentration ranges detected in water well samples collected by the DEQ and Wolverine.  Please note that this map is subject to change as additional sample results are obtained. 

    The water at several Rockford Public Schools was tested per a request by the school district, and no PFAS was found.

    DEQ and local and state health officials have also been attending several small neighborhood meetings with subdivision associations to discuss concerns about their residential drinking water quality.

  • Perfluorinated compound (PFC) Detections near House Street NE and Herrington Avenue

    Wolverine is currently working closely with state and local officials to collect data from the House Street Disposal Area, and the Rockford Tannery to understand the possible presence of PFCs. Proactive measures are underway to test residential water samples for PFCs. Some residential samples have detected PFCs at levels above the U.S. EPA lifetime health advisory level of 70 parts per trillion. Wolverine is providing bottled water and certified water filtration systems to homes with PFC detections. Wolverine along with state and local environmental experts and officials are sharing testing and other information with residents of Plainfield Township and the surrounding community.
