Kent County, Kentwood, Former Keeler Brass - 32nd Street

Former Keeler Brass 32nd Street Fig 1 PFAS Site Map Oct 2019Background

Located at 2929 32nd Street, this facility was owned by Keeler Brass from the 1960s through 2016. Processes at this location included automotive parts washing and metal plating. There are two known contaminant plumes: the central plume, primarily impacted with trichloroethylene (TCE), and the western plume, primarily impacted with metals from the plating operation. The release of plating fluids (western plume) was identified at the facility in the 1980s, which initiated an immediate cleanup and groundwater investigation and response, including the installation of a groundwater remediation system. There is a tributary to Plaster Creek present along the western boundary of the facility and residential homes present to the south of the facility, therefore, groundwater collection trenches were installed to prevent contaminated groundwater from migrating offsite in those locations. 

In 2018, as part of the Industrial Pretreatment Program (IPP), the City of Grand Rapids conducted a PFAS survey. PFAS was found at elevated levels in the wastewater generated at the former Keeler Brass facility. The wastewater is pretreated groundwater derived from the remediation systems, and additional treatment has been installed to address PFAS in the wastewater.

Recent Accomplishments

  • On November 26, 2019, EGLE received a work plan which outlined a number of groundwater wells to be sampled for PFAS downgradient of the western and central plumes.

Next Steps

  • Groundwater sampling in accordance with the submitted work plan.

Residential Well Testing/Alternate Water Information

  • There are no known drinking water wells in the area.
  • Nearby residences to the south and non-residential developments to the west are on municipal water; drinking water in the area is municipal from the city of Grand Rapids.
  • The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has sampled all municipal water supplies for PFAS. View the results for the City of Grand Rapids. 

Upcoming Community Engagement

  • None scheduled at this time.
Sampling: PFOS and PFOA Only

Sampling notes

  • July 2018 data summary table provided to EGLE by the city of Grand Rapids as part of the Industrial Pretreatment Program survey.
  • Groundwater treatment system influent, intermediate (as needed), and effluent sampling was conducted, however, only groundwater influent samples have been included in this table since they represent facility groundwater concentrations.

Former Keeler Brass - 32nd Street Historical Timeline

Keeler Brass operated at the property from the 1960s through 2016.  During that time, processes included automotive parts washing and plating. There are two known contaminant plumes: the central plume, primarily impacted with trichloroethylene (TCE), and the western plume, primarily impacted with metals from the plating operation. A release of plating fluids was identified at the facility in the 1980s, which initiated a groundwater investigation and response, including the installation of a groundwater remediation system. There is a tributary to Plaster Creek present along the western boundary of the facility and residential homes present to the south of the facility, therefore, groundwater collection trenches were installed to prevent contaminated groundwater from migrating offsite in those locations. 

In 2018, as part of the Industrial Pretreatment Program, the city of Grand Rapids conducted a PFAS survey. PFAS was found at elevated concentrations in the wastewater generated at the Former Keeler Brass Facility.   The wastewater is pretreated groundwater derived from the remediation systems, and additional treatment has been installed to address PFAS in the wastewater.

  • On May 22, 2019, based on the facility’s history and established presence of a groundwater collection trench for environmental remediation, EGLE sent a letter requesting that Keeler Brass develop a work plan to assess the presence of PFAS contaminants in the groundwater.
  • On June 28, 2019, Keeler Brass’ consultant responded to EGLE’s initial inquiry with a letter, wherein they refused to conduct an additional PFAS assessment, because their previous and ongoing work to delineate and remediate the plume for metals would also address PFAS and because they were installing additional pretreatment for PFAS in the wastewater.
  • On July 24, 2019, EGLE issued a violation notice further requesting a work plan for additional investigation, and following an October 23 meeting, the company’s consultant will be submitting a PFAS groundwater investigation plan. 
  • On October 23, 2019, EGLE met with Keeler Brass’ attorney and consultant to discuss the July 24, 2019 Violation Notice and discuss, in general terms, the scope of the requested workplan.
  • On November 3, 2019, EGLE received a laboratory analytical reports that were previously on file with the city of Grand Rapids Wastewater Treatment Plant.  The reports included results of additional groundwater treatment system influent and effluent PFAS sampling conducted as a requirement for IPP permit compliance and PFAS reduction requirements.  The sampling chart has been updated to reflect the additional samples.
  • On November 8, 2019, EGLE received additional information from the Kent County Health Department further confirming the absence of water wells in the area of PFAS investigation
