Du-Wel Metals On-Site Monitoring Well Sampling ResultsBackground

The former Du-Wel Metals Products (Du-Wel) site, located at 520 Heywood Street, operated a manufacturing facility on a 7.9-acre property from 1957 until 2002. Operations included electroplating, buffing and polishing of aluminum and zinc die casts, and then limited machining and warehousing before it closed in 2002. The building was then demolished and removed. From 1987 to 2002, Du-Wel conducted soil and groundwater investigations and soil corrective actions with the oversight of the Michigan Department of Environment, Great Lakes, and Energy (EGLE). From 2002 to present, EGLE has been conducting investigation and remediation activities for contaminants other than PFAS compounds, such as chlorinated solvents, at the site.

Recent Accomplishments

  • On May 10, 2019, EGLE began sampling residential wells, with 82 wells sampled through June 12, 2019.

Next StepsDu-Wel Metals Residential Well PFAS Sampling Map

  • Based on groundwater monitoring well results, EGLE will immediately begin sampling residential drinking water wells from residents who are within or very close to the current chlorinated solvent plume. These residences are currently being monitored for volatile organic compounds (VOCs).

Residential Well Testing/Alternate Water Information

  • EGLE has sampled all municipal water supplies for PFAS. The municipal supply results were Non-Detect for all PFAS. The Hartford Public School system uses municipal water. View the results for the city of Hartford.
  • Residential well testing will begin on May 10, 2019, for the residential wells located in the study area.
  • Bottled water is available at the local fire department to residents living in the study area who are waiting for their test results or installation of filters.  

Upcoming Community Engagement

  • None planned at this time.

Du-Wel Metals Historical Timeline

The former Du-Wel Metals Products (Du-Wel) operated a manufacturing facility on the property from 1957 until 2002, which included electroplating from approximately 1957 to 1986, during which wastewater was discharged to settling lagoons and a surface impoundment.  It conducted buffing and polishing of aluminum and zinc die casts between 1987 and 1992.  It then used the property for limited machining and warehousing between 1992 and 2001.  During 2002, the operation closed, and the manufacturing building was demolished and removed.

From 1987 through 2002, Du-Wel conducted soil and groundwater investigations and soil corrective actions at the site with the oversight of Department of Environment, Great Lakes, and Energy (EGLE), Waste and Hazardous Materials Division under the United States Resource Conservation and Recovery Act (RCRA). Some contaminated soil and plating wastes from several hot spots and lagoons were excavated in 1991 and 1992. By November 2002, a Voluntary Corrective Action Agreement under RCRA was signed and became effective. Under this agreement, Du-Wel completed an investigation and submitted a report; however, the full degree and extent of the groundwater contamination was not determined.

In 2003, Iverness Metal Castings Group, the parent company of Du-Wel, was acquired by Atchinson Casting Corporation, which later filed for bankruptcy under Chapter 7 of the United States Bankruptcy Code.  No work has been conducted at the property by the owner since 2003.  The property has since tax-reverted to Van Buren County.

The Du-Wel Metal Products facility includes much of the city in an area of residential, commercial, industrial, and agricultural land uses. A tributary to the Paw Paw River is immediately to the west of the site.  The city of Hartford has a municipal water supply that serves a finite number of residents.

  • On April 9, 2019, EGLE expanded its ongoing investigation into groundwater contamination at the former Du-Wel Metals site to include PFAS. EGLE collected 19 samples from groundwater monitoring wells on-site due to historical plating operations at the site.
  • On May 7, 2019, EGLE received the results from the groundwater sampling. The highest result on the property was 8,713.2 ppt PFOS+PFOA, and 8,808.3 ppt Total Tested PFAS. 
  • On May 7, 2019, EGLE received the results from the groundwater sampling. The highest result on the property was 8,713.2 ppt PFOS+PFOA, and 8,808.3 ppt Total Tested PFAS.
  • On May 15, 2019,  6:00 pm – 8:00 pm, EGLE hosted a Public Meeting at the Hartford Federated/Bible Church located at 65418 Red Arrow Highway in Hartford. MDHHS was in attendance and also gave a presentation.
